Cooling fins on beer bottles

 Cool beer bottles more quickly

This addresses the problem of only having warm beer and wanting to drink one as soon as possible.

Adding ridges to the bottles (or increasing the surface area in other ways) would mean less waiting. I'm not sure if Coca Cola was going for something similar with their glass bottles.

Lowering the fridge temperature could help too, but putting beer in the freezer kills the bubbles.

       Hmmm is this true though? There are two issues here, one is getting coldness to flow from the cooler into the glass, and the second is to get the coldness to flow from the glass into the beer. There are those high tech wine cooler things that apply large amounts of low-grade coldness to the surface of the glass, I think if the cooler has higher thermal conductivity than the glass, then the coldness will flow pretty quickly from the cooler into the glass, and I am not sure adding fins will help with that process.   

       The problem of transferring the coldness from the glass into the bottle is different. Is it the same actual pieces of cold, or is it like a substitution? i.e. does coldness flow like water, or does it propogate like waves? Anyway, we are limited here by the thermal conductivity of beer. Fins on the inside of the bottle would increase the surface area of the beer, but if you are concerned about too much coldness affecting the bubbles, I think a funny shaped bottle interior would similarly affect the flavour.

       I'm with [poc] on this and, besides, cooling fins would snap off in transit. A better option is probably a bottle-sized metal sleeve with fins that can be slid over the bottle to be cooled.

       The fins will tend to equalize temperature, and it's a bigger problem that beer warms up when not refrigerated. So what you need is a container with heat transfer sleeves into which you can place beer in the refrigerator and then take it out still in the original can or bottle.   

       On this note I imagine a separate beer-only refrigerator consisting only of a dozen beer sleeves, each with an individually controlled cooling loop to optimize cooling time without freezing the beer (or soda)

       //a separate beer-only refrigerator consisting only of a dozen beer sleeves, each with an individually controlled cooling loop to optimize cooling time without freezing the beer// Yes and these are commercially made and used in some off-licenses at point of sale.

       I keep a sealed food container in the freezer for this purpose. Aluminium can at room temp into ~1l water- antifreeze mix (saturated salt soln. also works down to -23C). Give it a good spin. Drinkable in a count of 100. Too long still. One day I'll have a huge copper block machined.
