Scientists may have finally solved a problem that has plagued beer drinkers for ages: Insufficient foam resiliency.
As any beer drinker can tell you, a tall glass of lager without a white, foamy head on top just doesn't look right. And even if you start out with one, it can dissipate fast. And that's just sad.
Now, microbiologists have identified the specific gene in yeast responsible for a beer's head and they say this discovery can lead to stronger, longer lasting, more aesthetically pleasing foam on your favorite brews.
The soaring drone of a full bagpipe and drum corps greeted thousands of people who marched into a Denver arena for the Great American Beer Festival this past weekend. The martial music seemed a fitting way to prepare the crowd to test their palates, and their fortitude, against 2,700 different beers made by some of the best breweries in the United States.
