At last a beer expert answers the age old question of whether beer should be served in a frozen mug. We keep a few beer glasses in the freezer but don't always use them. So is this good or bad?
The question in St. Louis Magazine went to beer guy, George Reisch and he said, "Imbibers who favor super-cold beer are "more after the refreshment aspect". But just like with wine flavor is affected by serving temperature, i.e., more characteristics and nuances of cold beverages become apparent at less cold temperatures.
In other words, icy cold beer loses some of its taste, but if you're after beer to cool off with after cutting grass, nuances aren't what you're looking for. If you're mainly drinking beer with dinner or for taste as you would with the micro brews, don't use a frosted glass.
Oh, and, the lighter lagers are best for those hot and sweaty times.
