The serious beer geek will like this passage:
But changing attitudes—and habits—isn’t going to be easy. Most draft systems are built to operate at 38 degrees. Fiddling with the temperature can affect carbonation and raise the risk of contaminated lines. Bars dedicated to the cause of good beer drinking (like Washington D.C.’s ChurchKey, which I’ve written about previously) can operate different draft lines at different temperatures, but it requires substantial investment in equipment, training, and maintenance.I'll admit I like a cold beer, but I also appreciate it as it warms up. I like higher alcohol beers, in particular Belgian beers, at warmer temperatures.
