Coldwave Beverage Chiller

Chills Drinks Fast

Coldwave is an instant drink chiller—and we mean instant. This clever pitcher is Made in the USA and will transform freshly brewed (and piping hot) coffee to icy cold in under two minutes. And it does it without diluting the flavor.

Founder David Dussault was looking for a way to avoid the watered-down flavor of his iced coffee.
So he created this pitcher and insert system to cool drinks down without affecting taste.

Keep the insert in the freezer, then place it in the pitcher full of beer, wine, or even carbonated drinks for an instant cool down. The chambers in the insert are made from high-density plastic tubes filled with (chemical-free) filtered water. It works similarly to an ice pack—but this plastic is BPA-free and dishwasher safe. Now that hot cup of coffee or tea can be iced—and just as tasty—in no time.

    Hello to The Grommet. I'm Dave Dussault, inventor of the Coldwave, a universal beverage chiller that makes a great iced coffee—super fresh. I'm happy to answer any questions you may have!

    hi- what is the capacity of the Chiller (with the insert in)?

    @Stephen It holds 16 oz with the insert in

    @Ariel

    Very easy to wash. I just give it a quick rinse. It's also dishwasher safe, if you want to give it a deep cleaning.

    Can you put beer in it.

    @TOBY The quick answer is yes!

    There is more to explain regarding carbonation. It can get affected. Some people are good as is. I like my beer with a good amount of carbonation. If I use it for a light beer, like an Amstel Light, it's good to use as is. If I use it for a heavy IPA, then I do the "water step" first. I cool down room temperature water, for about 10 seconds. It takes the initial hard chill off. And then it's gentle with the carbonation. You don't have to redo that step if you do more than one beer in a row.

    Can you clarify the dimensions of both the pitcher, and the of the insert I will place in the freezer? i believe the specs on the site are wrong (they show 12oz capacity and 5.5" x 5.5" x 6.25")

    @Dan The capacity is 16 oz. I'll grab a tape measure right now to double check everything... The dimensions 5.5" x 5.5" x 6.25" tall are of the pitcher, rounded up, including the handle. The insert is 4.25" x 4.25" x 6" tall. The base isn't square. It has two short sides that are 2.25" long.

    @David Thanks much for the quick response - wanted to be sure it would fit easily in our often overstuffed freezer :)

    Do you think you might be able to make a version with half of the tubes allowing for more carrying capacity?

  • David

    @Jonathan The quick answer is absolutely.

    I'm an engineer. I work with designers. It's all about trade-offs. The trade-off for more capacity is either time or size. If it cools in the same time, you need to increase the size to fit more beverage, make it taller for instance. If you want to take tubes out, the size can stay the same, and then the cooling is slower.

    I'm working on a whole line of spin-off Coldwaves, that you will hopefully see someday on the Grommet. One is a WineWave. It's basically like your question - less tubes, more volume. You'll be able to fit a whole bottle of wine. The cooling time is TBD because it's just on paper, but I'm thinking 5 minutes...

    What is the expected temperature change? You say cooling, but how is that defined? Also, how many cycles or uses before you need to refreeze?

  • David

    @Mark The temperature changes from boiling hot (like fresh coffee or tea) to iced cold (like a cold fridge) in 2 minutes.

    It's pretty cold after 1 minute. Some people just do 1 minute. You'd probably use ice after 1 minute, but it doesn't melt much at all. After 2 minutes, you don't need ice. If you let it go longer, it will approach 32 F but not freeze.

    It has the thermal capacity for 2 hot cycles or 6 room temperature cycles.

    Hi Dave - after i use this, do i have to freeze it overnight before i can use it again?

  • David

    @Doug Hi Doug. After one use, if you put the insert in the freezer, it will be ready to use in 1-2 hours.

    The time varies based on the freezer air flow and temperature. Also, if you put the insert in the pitcher, and then put them nested in the freezer, then the refreeze time is about double.

    This quick refreeze option can come in handy when a group shows up with cold beverages that aren't cold yet.

    Does the liquid (coffee, wine, etc.) freeze onto the chilling insert itself?

  • David
    David – Special Guest
    6/16/2017 3:29 PM

    @Sarah Nope. The insert is filled with purified water, so the beverage will approach 32 degrees but won't freeze.

    Love the sound of this, but I have used insulated plastic drinking glasses that I kept in freezer to keep cold. After a year the plastic got brittle, broke and all the gel insulation in the wall leaked and made a mess and rendered the glass unusable Can that happen here?

    @Bernice I believe there is a zero chance of the plastic cracking, or as close to zero as an engineer can be.

    This was one of the factors that went into choosing the plastic - HDPE (high density polyethylene). I did my own research, my own testing, and consulted a number of polymer chemists. I also went with my experience. HDPE is the same material used for the blue gel ice packs, which I've had in my freezer for forever. It's also the same material used for milk bottles.

    We made the first batch of Coldwaves a year and a half ago at this point, and we use them every day. I know with 100% certainty that they last that long. I'm very confident that they will last much longer.
