    By the time there's any condensate to wipe off the glass, hasn't the damage (i.e. heat from condensation) already been done? That's what warms the glass and its contents, not the water remaining on the side. So wiping it off won't prevent the warming.

      For the most part, but I expect the droplets of water increase the surface area of your cold beer container, thereby accelerating the warming process.

      You're right. Water has a high heat of vaporization. The amount of energy required to vaporize a given amount of water is close to 5 times the amount of energy that would be required to heat that same amount of water from 0 C to 100 C.

      So think of it as being a bit like taking the amount of water in the condensate, heating that to 500 C* and adding it to your beer. (* heating to that temperature without vaporizing)

      Your reflexive disdain is outdated. Lots of craft brewers are going to cans, at least here in Colorado. Much easier to take camping, lighter, probably cheaper and just as easy to recycle. Also, unlike even brown glass, and much better than pale glass, a can won't let *any* light through, so the beer is less likely to skunk.

      This is true. You will taste much more of the beer when you drink it slightly warmer. Also the reason why the supermarket bulk beer contains phrases such as "drink ice cold!!" -- you can't taste how crappy it is.

      American craft beers are also quite influential in Scandinavia, among both beer drinkers and as an influence on the local brewing scene. Brooklyn Brewery is popular enough that they're opening a brewery in Stockholm to fill local demand without having to ship the beer.

      Actually what I think is happening is probably the opposite of evaporative cooling. When you sweat for example, it makes you cold because as the water molecules are evaporating into a gas, it takes heat energy with it.

      Now condensation on the other hand results in the opposite. The heat from the water molecule is then put into the system (i.e. the glass of beer) so the water molecule sticks to it because it no longer has the energy it needed to remain in its gas form.

      In which case, wiping the condensation off doesn't reduce the temperature. In fact, it might actually be counterproductive because that water is no longer there to evaporate again, resulting in the cooling effect.

      Because they aren't as expensive to make and reasonably easily replicated by someone else who will sell it cheaper?

      Take your $500 bottle of scotch. It's probably aged for 25 or 30 years. So if I decided to make a competitor it would take me 25 years from when I started to bring it to market. And on every one of those 25 years I'd have to decide "I won't sell it all this year and make some money to pay the bills, I'll instead age it some more".

      Though I suspect the real answer is that wine and whiskey snobbery are off the charts. A $500 bottle of wine is quite possibly nicer than a $25 bottle of wine - it's not $475 nicer though. Wine just happens to be a luxury good that people use to show off wealth and hence the wealthy will spend a lot of money on it just so that everyone knows they have a lot of money. Beer doesn't have that status and hence people won't pay such ridiculous sums for it.

      That doesn't mean that "premium" beer isn't much better than "non-premium" beer. In fact it's a great thing for people who happen to like "premium" beers.

    The condensation pays a latent heat penalty, warming the beer when the beer is super cold. But conversely the evaporation pays back the latent heat penalty at some higher temperature. Where the equilibrium point is I'm not sure.

    But there is an easy solution to this problem: mist the outside of your beer glass with cold water. This will tie up all the condensation nucleation sites without paying the latent heat penalty.
