In 1982, only 50 breweries operated in the U.S. Just a mere six microbrews were open for business.

How times change. Now there are over 3,400 breweries, with new labels appearing almost daily. That doesn’t include the thousands of home brewers who try recipes in brew systems set up in their garages or man-caves or who join “libation associations” of fellow hopheads.

“Beeroisseurs” converge at brew fests to see what new beers familiar labels have developed, sample the offerings from new labels, and pick the brains of brew masters and each other.
