Reddit reviews True Cubes Clear Ice Cube Tray: 4-cube tray

This is already done by another company in a small form that fits perfectly in an OF glass. True Cubes is the name, and it's fantastic.https://amazon.com/True-Cubes-Clear-Cube-Tray/dp/B07422QWCP/ref=sr_1_4?keywords=ice+cube+maker+clear&qid=1558703786&s=gateway&sr=8-4

Looks goofy as hell, but works like a charm. On mobile, so please excuse editing.

I have been struggling to make clear ice...would be so proud to serve an old fashioned with quality ice at my home bar!!!

Came across this, read some reviews and I think I'm gonna try this...

If link fails, it's called TRUE CUBES CKEAR ICE CUBE TRAY on Amazon. $39.99

That looks awesome! I really do feel that clear ice makes for a better cocktail taste as well as obviously the look of it. The way most of us make "craft" cocktails, its a detail that can be overlooked, but well worth the extra effort.

I got the below linked TrueCubes clear ice tray system and it works really well. Same concept (open cooler/keep the top/dispose the bottom) but they use a pair silicone inserts instead of having to cut at the end. It only makes 4 2"x2" cubes at a time but I just keep making them until I fill a large ziplock bag then I am good for a while. I have had it for a couple years and have used it countless times. Holds up really well.

I'm my experience it's not minerals that make ice cloudy. Of course, dissolved substances can affect the quality and appearance of your ice but almost all the cloudiness is from air bubbles.

I have a couple different ice cube trays that are specifically made to make clear ice (they are ungodly expensive, like $40 to make one ice cube) this "true cubes" 4 ice cube tray https://amzn.to/2llib82 and the "peak" single ice cube tray https://amzn.to/2mUKU49. Both work on approximately the same principles, which I will try to explain as I understand them. I think it is helpful to link them because you can go see pictures of how they work.

They are both insulated large containers, with side insulation and bottom insulation (closed cell foam, I think). Then they have a mold you insert and a top mold with some holes. The clear ice forms on top. The middle ice in the mold below the top is just waste ice.

I believe the principles are as follows:

(1) If you freeze water quickly dissolved air and bubbles will make it cloudy. Therefore they are insulated so it takes like 12 hours to 24 hours to make one ice cube, very slowly.

(2) If you freeze water together in one block it will include air bubbles inevitably - so both these models have the ice "separated" halfway through by a porous divider so that the bottom of the ice is kept separate for the top. The top part is the clear part. The air bubbles move down somehow - I am honestly not 100% understanding the physics here since while ice is less dense than water, air bubbles are definitely less dense than ice. But when I take apart the mold the bottom part always has some air bubbles in it.


You still have you use pretty clean/pure water and some people say they have to boil as well. However, boiling water on its own is not enough to get clear ice - you have to freeze it in a special way.

FWIW if you are interested in the kits the peak ice maker is slightly harder to use/assemble and more expensive since it makes only one ice cube, but I feel it makes a better clear ice cube. That could be my own bias though because since it is more annoying I feel it must be worth the effort. Both are fine.

Or you could just buy a "good enough" gizmo on Amazon for $40 to make clear ice cubes. It's basically a smaller easier to use version of the beer cooler hack. https://www.amazon.com/dp/B07422QWCP/ref=psdc_2469549011_t1_B075DLBHBJ
