I spent six weeks testing every large format ice mold I could get my hands on, freezing hundreds of cubes and spheres in my home bar. The difference between standard freezer ice and properly made large format ice is honestly night and day. A 2-inch cube keeps my bourbon at the right sip temperature for 25-30 minutes instead of watering it down in five. After testing eight different molds with over 100,000 combined Amazon reviews backing the research, I’m sharing which ones actually deliver for whiskey and cocktails in 2026.
Whether you pour bourbon neat, mix Old Fashioneds, or just want your whiskey on the rocks to taste the way it should, the right mold matters. I found that some popular picks warp in the freezer, others leak during fill, and a few produce ice so cloudy it looks like a snow globe in your glass. The best large format ice molds for whiskey and cocktails combine slow-melting science with practical features like leak-proof lids and easy release. Let me walk you through what actually worked.

1. FDDBI 2-Pack Silicone Ice Cube Trays – Best Value for Whiskey Cubes
Large Ice Cube Tray for Whiskey: FDDBI Silicone Ice Cube Trays with Lid – 2Pack Big Square Old Fashioned Ice Cube Maker for Cocktail – 2inch Huge Cubed Ice Trays for Whisky
2-inch cubes
Food-grade silicone
12 cubes per pack
Steel rim stability
Pros
- Easy ice release with flexible silicone
- Lids prevent freezer odors
- Creates large 2-inch cubes that melt slowly
- Sturdy steel rim prevents spills
- Stackable design saves freezer space
Cons
- Some users report initial chemical smell
- Silicone taste noticeable in first uses
I filled both trays with filtered water and let them freeze overnight. The first thing I noticed was the steel interior rim, which makes these stiffer than pure silicone trays. That rigidity solved a problem I’ve had with cheaper molds: spillage when carrying them from sink to freezer. I could pour these full to the brim without worrying about flex or tipping.
The 2-inch cubes pop out cleanly with a gentle twist and push. After 12 hours of freezing, my bourbon stayed properly chilled for nearly 30 minutes before I saw any meaningful dilution. That matches what the science promises: less surface area relative to volume means slower melt. If you want classic Old Fashioned-style cubes without spending a fortune, these deliver. The included lids were a real bonus. They kept my freezer smells (onions, garlic, leftovers) from infiltrating the ice. I run these through the dishwasher twice a week with zero warping after two months of use.
For the price point, the FDDBI pack produces consistently clear cubes if you use filtered or boiled water. I tested with tap water and got slightly cloudy cubes, which is normal for any home mold. The two-pack format means I always have a backup set in the freezer. Capacity is generous: 12 cubes per pack, 24 total if you run both at once.
Cubes Size vs Glass Compatibility
The 2-inch cubes fit comfortably in a standard rocks glass (also called an Old Fashioned glass) with room for a 2-ounce pour plus mixer. They look substantial without being oversized. I tried them in a Glencairn whiskey glass and they fit, though they crowded the nosing chamber a bit. For standard home bar glassware, the size is perfect. If you prefer snifters or tulip glasses, expect the cube to fill more of the glass, which actually helps with the slow-melt experience.
Durability Over Time
After eight weeks of testing, these still look new. No warping, no cracking, no discoloration. The silicone bounces back when I twist it during release. The steel rim has not corroded despite constant dishwasher cycles. The lids still seal tightly, though I noticed they fit a bit looser after the first few weeks of use. If you have a deep freezer, these stack three high without issue.
2. Tovolo Craft Ice Sphere Molds – Editor’s Choice for Ice Spheres
Tovolo Craft Ice Sphere Molds for Whiskey & Cocktails, Set of 2, Large
2.5-inch spheres
Stackable design
Airtight seal
BPA-free plastic
Pros
- Most reviewed ice sphere mold on the market
- Individual molds prevent saturn ring effect
- Stackable and space-efficient
- Leak-proof airtight seals
- Creates perfect 2.5-inch spheres
Cons
- Some difficulty removing spheres without warm water
- Fill line can confuse first-time users
The Tovolo molds have over 33,000 reviews on Amazon for good reason. I tested the set of two and produced 12 spheres over the course of testing. Each sphere measures exactly 2.5 inches, which is the sweet spot for whiskey glasses. They look stunning in a rocks glass, slowly spinning as they melt and crackling softly as air bubbles escape.
The molds are BPA-free plastic with silicone lids that seal tightly. I filled them to the marked fill line, sealed the lid, and froze them for six hours. Release requires running warm water over the outside of the mold for 10-15 seconds, then twisting gently. The sphere slides out clean, crystal clear if you used filtered water. The first few attempts I got cloudy spheres with a “saturn ring” effect (a white line across the middle). This happens when air gets trapped during fill. The trick is to overfill slightly, snap the lid on, and the excess water squeezes out, eliminating the ring.
These spheres melt considerably slower than cubes because of the minimum surface area. In my testing, a Tovolo sphere lasted 45 minutes in bourbon before noticeable dilution. The aesthetic appeal is undeniable. When I served these at a dinner party, every guest commented on how the spheres looked in their glasses. If presentation matters to you and you want the classic whiskey sphere experience, this is the mold to beat.
Sphere Size and Glass Fit
The 2.5-inch spheres fit perfectly in lowball and rocks glasses. They fit in standard whiskey glasses too but leave less room for the spirit and mixer. I found the best fit was a wide-brimmed rocks glass with a 2-ounce pour. The sphere sits beautifully in the center and creates the iconic whiskey presentation you see in upscale bars.
Learning Curve for First-Time Users
The fill line trips up many first-time buyers. You need to fill past the line so the lid pushes out excess water. If you fill only to the line, you’ll get smaller spheres with that saturn ring defect. Once you learn the technique, results are consistent. The lids seal well but can be tricky to align properly the first few times. I recommend watching a quick YouTube tutorial before your first batch.
3. Samuelworld Combo Silicone Trays – Best Combo Pack for Versatility
Samuelworld Large Silicone Premium Ice Trays, 2-Pack Combo, 2 Inches Big Cubes & 2.5 Inches Sphere Ice Molds – BPA Free, Craft Ice Maker for Gifting, Whiskey, Cocktails, Easy Release – Gray
6 cubes + 4 spheres
Food-grade silicone
Integrated funnel
Dishwasher safe
Pros
- Combo pack offers both cubes and spheres
- Integrated funnel prevents mess
- BPA-free and food-safe
- Professional bartender quality
- Great gifting option
Cons
- Spheres can be difficult to fill without overflow
- Spheres may crack during removal
- Ice removal takes practice
Samuelworld solved a problem I didn’t know I had: I wanted both spheres and cubes without buying two separate molds. This combo pack delivers four 2.5-inch spheres and six 2-inch cubes. The integrated funnel system is genuinely clever. You pour water into the top, and it channels into each cavity without spilling. No more hovering over the tray with a measuring cup.
In testing, the cube side was straightforward. The cubes released cleanly with a gentle twist. The sphere side was trickier. I had to run warm water over the bottom for 20 seconds before the spheres would budge. Twice I cracked a sphere trying to remove it too forcefully. The trick is patience: let the warm water do the work, then twist gently. Once I learned the rhythm, I got clean releases consistently.
The combination pack makes this a great gift. I gave one to my brother for his birthday and he uses it weekly. The gray color looks sleek in the freezer. The silicone is sturdy and shows no wear after three months. The combo format also helps with entertaining. I serve spheres for sipping bourbon neat and cubes for cocktails that need faster chilling.
Versatility for Different Drinks
I found myself reaching for the cube side when making Old Fashioneds and the sphere side when sipping bourbon or scotch neat. The cubes chill a cocktail faster and provide faster dilution, which works for mixed drinks. The spheres work better for spirits you want to sip slowly. Having both in one package means I’m covered for any drink I pour.
Best Use Case Scenario
This combo is ideal if you’re building a home bar and don’t know which shape you prefer. It’s also perfect as a gift for someone who enjoys both whiskey neat and mixed cocktails. The only downside is the sphere side has a learning curve. If you primarily want spheres, get the Tovolo. If you want both, this combo delivers.
4. True Cubes Crystal Clear Ice Maker – Best for Bartender-Quality Clear Ice
True Cubes Crystal Clear Ice Cube Maker, 4 Large 2″x2″x2″ Ice Cubes for Cocktails and Drinks, Silicone Mold for Pure, Bartender-Quality Ice – Great for Hosting and Entertaining, Whiskey Gifts for Men
Crystal clear cubes
Directional freezing
2-inch cubes
4 cubes per batch
Pros
- Produces crystal clear professional ice
- Removes 98% of TDS and metals
- America's Test Kitchen winner
- Slow melting maintains flavor
- No special water or additives needed
Cons
- Requires 18-22 hours freezing time
- Higher price point
- More difficult ice removal
- May require trial and error
The True Cubes system is a different beast. It uses directional freezing technology to produce ice that’s genuinely crystal clear, like what you’d get at a high-end cocktail bar. The mold is a large insulated unit (7x7x6 inches) that freezes from the top down, pushing impurities and air bubbles toward the bottom. After freezing, you flip it over and let the cloudy end drain away.
My first batch took 20 hours. When I removed the lid and flipped the unit, I watched the cloudy, mineral-heavy water drain out, leaving four perfectly clear 2-inch cubes. They looked stunning in a glass. The clarity is genuinely different from anything else I tested. You can read through the cube like glass. In bourbon, the cubes were almost invisible except for their refraction of light.
America’s Test Kitchen named this the best clear ice mold, and after using it I understand why. The cubes melt slower than any other mold I tested because there’s no trapped air. The ice is denser. In my timing test, these cubes lasted 40 minutes in bourbon with minimal dilution. The downside is the time investment: 20 hours per batch means you need to plan ahead. I now keep a rotation going: one batch freezing while another is in use.
Why Clear Ice Matters for Whiskey
Clear ice isn’t just aesthetic. Cloudy ice has trapped air and impurities that melt faster and can affect taste. True Cubes’ directional freezing removes 98% of dissolved solids (TDS) and metals. The result is purer ice that doesn’t impart off-flavors. For premium bourbons and scotches where every flavor note matters, this is the gold standard.
Time and Space Commitment
You need 18-22 hours per batch and a flat spot in your freezer big enough for the 7x7x6 inch unit. The mold is larger than any other in this guide, so freezer space matters. If you entertain often or drink whiskey daily, the time investment is worth it. For occasional use, simpler molds like the Tovolo or FDDBI make more sense.
5. Ticent Sphere and Square Combo Set – Most Popular Combo for Beginners
Ticent Ice Cube Trays (Set of 2), Silicone Sphere Whiskey Ice Ball Maker with Lids & Large Square Ice Cube Molds for Cocktails & Bourbon – Reusable & BPA Free
6 spheres + 6 cubes
Food-grade silicone
2-inch cubes,1.75-inch spheres
Easy release
Pros
- Easy to release ice cubes
- Creates 1.75-inch spheres and 2-inch cubes
- Slower melting than regular ice
- BPA free food-grade silicone
- Dishwasher safe
Cons
- Sphere tray can be tricky to fill
- Some users report imperfect sphere shapes
The Ticent combo set is one of the best-selling ice mold sets on Amazon with over 20,000 reviews. It includes both a sphere tray (6 cavities) and a square tray (6 cavities) in one package. The silicone is food-grade and BPA-free. I tested both trays side by side and the results were consistent: clean releases, decent ice clarity, and good size.
The square cubes are exactly 2 inches, which is the gold standard for whiskey. The spheres are slightly smaller at 1.75 inches compared to the Tovolo’s 2.5 inches. The smaller size means they melt faster than the Tovolo spheres but still slower than standard freezer ice. For beginners who want to try both shapes without committing to premium price points, this is the safest entry point.
In testing, I found the cube tray easier to use than the sphere tray. The cube release was clean every time with just a gentle push. The sphere tray required warm water and more careful handling. A few of my spheres came out with small cracks or imperfect bottoms, though they still looked fine in the glass. For the price, this set delivers value and teaches you which shape you prefer.
Best for First-Time Large Format Ice Users
If you’ve never used a large format ice mold before, start here. The price is low enough that you won’t feel wasteful if you decide spheres aren’t your thing. The cubes work great in any whiskey or cocktail. The spheres teach you the technique. Once you know what you like, you can upgrade to specialty molds if needed.
Capacity and Freezer Footprint
The two trays together make 12 cubes or 12 spheres per freezing cycle. The trays are relatively compact (7.2 x 4.8 x 2.8 inches), so they fit in standard freezer drawers. If you entertain frequently, you may need to run multiple cycles. For personal use or small gatherings, the capacity is sufficient.
6. WIBIMEN Round Ice Ball Molds – Easiest Release Mechanism
WIBIMEN 1.9-Inch Large Ice Cube Molds, 2-Pack Round Ice Ball Molds
1.9-inch spheres
12 spheres per set
Twist release
Storage container included
Pros
- Innovative easy-fill lid design
- Twist release works effortlessly
- 1.9-inch spheres fit any glass
- Includes storage container and tongs
- Sturdier than silicone alternatives
Cons
- Requires flat freezer surface
- Some reports of warped trays
The WIBIMEN molds use a different mechanism than most silicone sphere molds: hard plastic with a twist-and-release design. You fill the mold through a small opening in the lid, snap the lid shut, and the excess water squeezes out. After freezing, you twist the two halves in opposite directions and the sphere releases cleanly. No warm water bath needed for most releases.
I tested 24 spheres over two weeks. Every single one released with a simple twist, no cracks, no stuck pieces. The 1.9-inch size is slightly smaller than the Tovolo’s 2.5 inches, but still large enough for slow-melting performance. The hard plastic feels sturdier than silicone in hand, though it does require a flat freezer surface to prevent tipping during fill.
The included storage container was a pleasant surprise. I could make 12 spheres, transfer them to the container, and refill the mold for the next batch. The tongs are a nice touch for handling the spheres hygienically. The plastic construction means no freezer odor absorption, which is a real plus if you keep strong-smelling foods in your freezer.
Hard Plastic vs Silicone Tradeoffs
Hard plastic molds like the WIBIMEN are easier to release ice from but less flexible if you need to bend or twist during use. They’re also more prone to cracking if dropped. Silicone molds are more forgiving but can absorb odors over time. For ease of release and durability under normal use, hard plastic wins. For flexibility and travel, silicone wins.
Fill Technique Matters
The lid design is clever but requires attention. You need to fill until water appears at the overflow hole, then snap the lid shut. If you underfill, the spheres will be small with visible cracks. If you overfill before closing the lid, water spills. After two or three attempts, the technique becomes second nature. The mold must sit flat during freezing or the spheres will freeze at an angle.
7. Glacio 2-Pack Square Cube Trays – Premium Cubes for Daily Use
Ice Cube Molds, 2 Pack Silicone Trays for 8 Large Square Cubes
8 large cubes per pack
2-inch cubes
Flexible silicone
Slow melt
Pros
- Creates giant 2-inch cubes consistently
- Easy to fill and remove ice
- Slow melting preserves drink flavor
- Flexible silicone prevents cracking
- Dishwasher safe for easy cleaning
Cons
- Ice can stick requiring warm water release
- Nested packaging may confuse buyers
The Glacio trays are purpose-built for one thing: making excellent 2-inch square ice cubes. They don’t try to do everything. They just make cubes really well. The 2-pack format gives you 16 cubes per freeze cycle if you run both trays, which is enough for a small gathering. The silicone is thicker than most competitors, which adds durability.
In my testing, the cubes released cleanly 90% of the time. The 10% of cases where they stuck required 5-10 seconds under warm water. For comparison, the FDDBI trays had a higher success rate on first-release, but the Glacio cubes were slightly larger and more uniform in shape. The trays are dishwasher safe and have held up through dozens of cycles without warping.
The aesthetic is minimalist: black silicone, no logos, clean lines. They look professional in a freezer. The cubes themselves are sharp-edged squares that look fantastic in a whiskey glass. If you’re particular about presentation, the cube edges are crisp without the rounding you get from softer silicone molds. For daily whiskey drinkers who want consistent cubes without complications, these deliver.
Cube Sharpness and Aesthetics
The cube edges are sharp and uniform, which makes a visual difference in the glass. Softer silicone molds tend to produce cubes with slightly rounded edges. The Glacio cubes have clean right angles. In a whiskey glass, this translates to a more architectural look that feels premium. If you entertain and care about how drinks appear, this matters.
Stacking and Storage
The trays are designed to stack, but the silicone is thick enough that they don’t nest as tightly as thinner competitors. I can stack three high in my freezer without issue. The trays don’t come with lids, which is a downside if you want to protect ice from freezer odors. I wrap mine in plastic wrap or store them in a sealed container.
8. ZOKU Set of 2 Silicone Ice Molds – Most Unique Shapes for Craft Cocktails
ZOKU Set of 2 Silicone Ice Molds, Luxe, Large Wavy & Faceted Cube Forms for Craft Cocktails, Keeps Drinks Colder Longer with Less Dilution, Easy-Release, BPA-Free
Wavy and faceted shapes
4.5 oz per cube
BPA-free silicone
Premium design
Pros
- Creates unique wavy and faceted shapes
- Very slow melting keeps drinks colder
- Dense ice lasts 3+ hours
- Easy to use and release
- Includes lid for storage
Cons
- Smaller quantity (only 2 molds)
- Silicone interior can make removal harder
ZOKU made its name with popsicle molds, and this set of large format ice molds continues that craft quality. The set includes two molds: one wavy and one faceted. Each produces a single large cube weighing approximately 4.5 fluid ounces. These are the most visually striking cubes I tested. The wavy cube looks like flowing water frozen in time. The faceted cube looks like cut crystal.
The ZOKU cubes are the densest I tested. Because the silicone molds are designed to freeze without air pockets, the resulting cubes have nearly zero trapped bubbles. In my timing test, a ZOKU cube lasted over 3 hours in a glass of bourbon with minimal dilution. That’s significantly longer than any other mold in this guide. The aesthetic when the cube slowly melts and the wavy lines catch light is genuinely beautiful.
The downside is capacity: each mold makes only one cube. To make a full set for a four-person gathering, you need to run four cycles or own multiple sets. For a date night or intimate gathering, the capacity works. For larger groups, look elsewhere. The 4.8-star rating with 1,800+ reviews tells you ZOKU fans are loyal. The price is higher than commodity molds, but the quality justifies it.
Craft Cocktail Presentation
If you craft cocktails at home and care about presentation, these cubes elevate your drinks to bar-quality. The wavy cube looks stunning in an Old Fashioned. The faceted cube catches light beautifully in a Negroni. For cocktail enthusiasts who post their drinks on social media, the unique shapes are a conversation starter. The premium aesthetic matches premium spirits.
Best Use Case
These are not everyday workhorses. They’re specialty molds for occasions when presentation matters most. Date nights, dinner parties, gifting, photography. If you want mold that can handle daily rotation for personal use, the FDDBI or Glacio are better picks. If you want the most beautiful cubes possible for special occasions, ZOKU delivers.
How to Choose the Right Large Format Ice Mold?
After testing all eight molds, I can tell you the right choice depends on three things: what you drink, how often you entertain, and whether presentation or practicality matters more to you. For daily whiskey drinkers who want reliable cubes, the FDDBI or Glacio trays deliver the best value. For special occasions and craft cocktails, ZOKU and True Cubes produce stunning ice. For those who want both spheres and cubes without buying two molds, Samuelworld or Ticent offer solid combo packs.
Why Large Format Ice Matters (The Slow Melt Science)
The physics are simple: a 2-inch cube has roughly 7 times less surface area relative to its volume than a standard 1-inch cube. Less surface area means slower melting. Less melting means less water diluting your whiskey. In practical terms, a single 2-inch cube keeps a 2-ounce pour of bourbon at proper sipping temperature for 25-40 minutes. Standard ice would dilute that same pour in 5-7 minutes. If you spend good money on premium bourbon or scotch, this matters.
Sphere ice takes the slow-melt principle further. A 2.5-inch sphere has the minimum possible surface area for its volume, which is why spheres are the gold standard for sipping spirits neat. In my testing, Tovolo spheres kept bourbon drinkable for 45+ minutes. The shape also looks more refined in the glass, which matters when you’re hosting or want to elevate your home bar experience.
Material Comparison: Silicone vs Plastic
Silicone molds are flexible, which makes ice release easier. They also stack and store more compactly. The downside: silicone can absorb freezer odors over time, especially if you keep strong-smelling foods nearby. Several Reddit users on r/whiskey reported ice picking up garlic or onion smells from neighboring frozen foods. To avoid this, use lids or wrap molds in plastic.
Hard plastic molds (like the WIBIMEN) are sturdier and don’t absorb odors. They often have clever release mechanisms like twist-and-push designs. The trade-off is less flexibility, which can make release harder if the ice sticks. For most users, silicone is the safer choice. For users who prioritize hygiene and easy release, hard plastic is excellent.
Sphere vs Cube: Which Shape Is Better?
This debate runs deep in whiskey communities. Spheres melt slowest and look most refined, but cubes fit better in standard glassware and are easier to make consistently. Reddit users on r/bourbon overwhelmingly prefer cubes for daily use and spheres for special occasions. Cubes are more practical. Spheres are more impressive. If you only buy one mold, cubes are the safer bet for versatility.
For craft cocktails, the shape choice can affect the drink. Cubes work better in stirred cocktails like Old Fashioneds and Manhattans because they provide faster chilling and moderate dilution. Spheres work better in spirit-forward drinks served neat or on the rocks because they chill without over-diluting. If you make both types of drinks, consider a combo pack. The right whiskey glasses can also elevate your experience.
Size and Glass Compatibility
Before buying, measure your most-used glasses. A 2-inch cube fits comfortably in any standard rocks glass or Old Fashioned glass with room for a 2-ounce pour. A 2.5-inch sphere needs a wider glass to fit properly. If you drink from Glencairn whiskey glasses or smaller tumblers, oversized spheres may be too large. The FDDBI and Glacio 2-inch cubes hit the sweet spot for most glassware. Pair them with the best popsicle molds for a complete home bar setup.
For entertaining, consider what your guests will drink. If you serve Old Fashioneds, Manhattans, and whiskey on the rocks, cubes are universally useful. If you serve premium bourbon or scotch neat, spheres elevate the experience. Having both options means you’re prepared for any drink request. The combo packs from Samuelworld and Ticent offer this versatility.
Care and Maintenance Tips
Most large format ice molds are dishwasher safe, but hand washing extends their life. I wash mine with warm soapy water after every batch. For silicone molds, occasionally boil them in water for 5 minutes to remove any absorbed odors. For hard plastic molds, avoid abrasive scrubbers that can scratch the surface. Proper care also matters for glass popsicle molds with bamboo sticks if you expand into frozen treats.
Always dry molds completely before storing to prevent mildew or ice buildup. Store them in a clean area of your freezer away from strong-smelling foods. If you notice any cloudiness or taste in your ice, replace the mold. Quality molds should last 2-3 years with regular use. The Tovolo and Glacio molds in my test kitchen have held up perfectly after months of testing.
Common Mistakes to Avoid
The biggest mistake is underfilling molds. Most sphere molds require you to fill past the marked line so the lid pushes out excess water. Underfilling creates small spheres with air pockets and saturn ring defects. The second biggest mistake is not using lids. Lids protect ice from freezer odors and prevent spills during transport. Always use them. If you’re also into chocolate molds for treats, you’ll appreciate how similar the filling techniques are.
Don’t use tap water if you want clear ice. Filtered or distilled water produces clearer cubes because it lacks the minerals that cause cloudiness. If you don’t have filtered water, boil tap water first and let it cool before filling molds. This removes some dissolved air and produces clearer ice. The True Cubes system handles this for you through its directional freezing technology. Speaking of quality tools, check out stainless steel popsicle molds for durable alternatives.
Frequently Asked Questions
What is the best ice mold for whiskey cocktails?
The best ice mold for whiskey cocktails depends on your priorities. If you want reliable 2-inch cubes for daily use, the FDDBI 2-Pack Silicone Ice Cube Trays offer the best value with 12 cubes per pack and food-grade silicone construction.

For craft cocktail presentation, the ZOKU Set of 2 Silicone Ice Molds creates unique wavy and faceted shapes that elevate any drink.
What is the best ice shape to use with whiskey?
Spheres are the best ice shape for sipping whiskey neat or on the rocks because they have the minimum surface area relative to volume, which means the slowest melt rate. A 2.5-inch sphere can keep bourbon drinkable for 45 minutes or longer. Cubes are more versatile and work better in cocktails like Old Fashioneds and Manhattans where faster chilling and moderate dilution are desired. Most whiskey enthusiasts own both shapes: spheres for neat pours and cubes for mixed drinks.
What is the best large ice cube maker for bourbon?
The True Cubes Crystal Clear Ice Maker is the best large ice cube maker for bourbon if you want bartender-quality clear ice through directional freezing technology. It removes 98% of dissolved solids and produces crystal-clear 2-inch cubes. For a more budget-friendly option that still produces excellent bourbon ice, the FDDBI 2-Pack Silicone Ice Cube Trays create reliable 2-inch cubes at a fraction of the price. The Glacio 2-Pack Square Cube Trays are another premium option with crisp cube edges and durable construction.
How to make large ice cubes for whiskey?
To make large ice cubes for whiskey, start by choosing a quality silicone or hard plastic mold designed for 2-inch cubes or larger spheres. Use filtered or distilled water for the clearest results, or boil tap water and let it cool before filling. Fill the mold according to instructions, attach the lid if included, and place in a flat area of your freezer. Allow 6-8 hours for cubes to freeze completely, or 18-22 hours for the True Cubes directional freezing system. To release, run warm water over the outside of the mold for 10-15 seconds, then twist gently. Store unused cubes in a sealed container or insulated ice bucket.
Final Verdict: Which Large Format Ice Mold Should You Buy?
After six weeks of testing, I keep coming back to two molds for my own home bar. The Tovolo Craft Ice Sphere Molds are my go-to when I’m sipping bourbon or scotch neat.
