Does beer cool down faster in a can than a bottle? Does the cardboard 6 packer make a difference in how long it takes to cool down?
To answer these questions, I used the 4 channel temperature logger that I built a few years ago, a beer bottle, an aluminum can, a cardboard 6 pack holder, and our house fridge.
The short answer is that the difference in the time to cool from 24C to 10C for liquid in a can or a bottle was insignificant. Sort of surprisingly putting the bottle and can in the cardboard 6 pack holder added 50% to the cooldown time. A little more surprising was that the temperature in the fridge varies over a wider range than I was expecting.
