The craft beer scene is a far different animal today than it was in the late 1970s. That might seem like an obvious statement, but think about how much different things were when Ken Grossman started Sierra Nevada Brewing Company. There were no labs to buy yeast from, no catalogs of different hop verities to choose from and no other craft breweries to buy used equipment from. All of the equipment they used to start Sierra Nevada was made from scrap metal and old dairy farm equipment. Fast forward thirty-five years later and Sierra Nevada is one the largest craft breweries in the country and producing over a million barrels of beer each year.
