I thought I had a genius idea about wine too but just realized it's in their ad too lol. But yah it's been great for coffee and the one time I needed to chill a glass of wine fast. I've only ever needed to do one coffee at a time so I guess it wouldn't be useful for multiple cups but it's perfect for just me ðŸ˜

I prefer iced coffee over hot anytime of the year.
This is the easiest and fastest method of preparing iced coffee without being watered down that I have ever tried. I have tried many ways, including refrigerator iced coffee (brewed in fridge), k-cups sold specifically to make iced coffee, and just letting the coffee cook on porch in winter lol. None of these are convenient or quick, and the k-cups taste watered down.
Now, I usually use regular k-cups, brew, and then pour immediately in the chiller. While I wait a couple minutes to cool, I prepare add ice to my glass. Usually by the time I get my glass of ice ready, coffee is about done in chiller. I just pour in my glass of ice, and bam, done!! I rinse the chiller out and put it back in the freezer. I only take the chiller apart and replace the water inside once every week or two. This is quick and has worked fine for me. Not sure if it is specified to replace water or when, but since the water inside doesn't touch the coffee, it doesn't need to be done often at all. I mainly replace the water just in case some is lost to evaporation after awhile.

I suggest that if you use a j-cup, you brew into a cup with a pouring lip. I use a glass measuring cup for this purpose. When I used a regular coffee cup, I spilled some pouring into the chiller every time. That was an easy fix, and if your pouring from a coffee carafe, that will not be an issue. Buy it! I have used this everyday since purchase months ago, and it is still working great.

Once I discovered this, I can't go back. I got my first one as a gift and it changed my ice coffee routine. I think I went over the max line one time and the other plastic did crack. So had to repurchase right away. As long as you fill under the max line, these will last. If you like cold drinks, this is a must!

I bought a Hyperchiller for office coffee - summer in Alabama average 10,000 degrees, so hot coffee seems like a waste. After using it a couple of times, I can understand the hype, but I also noticed more than a few things that merit improvement.

Hyperchiller works as advertised-sort of. I won't get into the minutia of why this isn't an iced coffee maker, as I'm sure other reviewers have noted. This isn't a replacement for a Toddy or French press or bean bag or however you prefer to make cold brew coffee-rather, this is something that takes a hotter beverage and makes it colder, and in that regard it works really, really well. If I pour coffee fresh from brewing into the fully-frozen Hyperchiller and let it sit for a minute, the coffee comes out pretty cool. Not freezing cold- hot coffee poured into this is never going to be an iceless experience- but cool enough that I can add ice and milk and not water my drink down. For drinks that are often room temperature and chilled with ice- wine and whiskey come to mind- I think the Hyperchiller can chill them down to that ice cold level, but for near-boiling liquids? Nah. That has more to do with science than any design flaw, though, so I'm fine with it.

Something I'm not fine with it the pouring mechanism. I understand the wider you make the opening the more likely you'll lose temperature and have worse results, but the lid is designed with an angled slot sort of design that's very shallow and awkward to fill, at least with a coffee carafe. Even taking a paper cup and making a sort of funnel the pour the coffee in always results in a puddle of coffee around the base of the Hyperchiller. I'll probably bring in a small measuring cup next week to see how that works, but the fact that it's immediately awkward to pour something in means it will end up being a bad user experience. Why not design the lid with gasket-sealed pouring spouts like travel mugs? You open one, dump your liquid in, close it, and it automatically seals. Make the caps the diameter of a quarter and you have a foolproof pouring mechanism. Sure, it adds more to R&D, but it's worth it.

Getting the chilled coffee into the cup is a better experience, but not without some quirks as well, namely the lid vents, which are meant to help with freezing/refreezing so the water doesn't stress the steel. The way the pouring spout is designed, you have to almost invert the Hyperchiller to get everything out, which will cause any melted water to pour out of the vent holes as well. There's more than likely a better way to design either the spout or the vents to prevent this.

All in all, Hyperchiller is good, but it could be great. There are some design flaws that don't put it in a design museum, but the intentions are there. Hopefully, they'll absorb all the feedback we're leaving and make an even better Model 2.

Product works really well in quickly chilling hot coffee. I have a nespresso and it cools my hot coffee and espressos quickly without diluting it. I wish it would fit underneath the Nespresso machine to brew directly into the chiller but otherwise, I love it! If I'm just using it for one coffee, I just rinse it out and put it right back in the freezer so clean up is easy!
