Craft beer is sweeping the nation and changing the beverage industry. Parts of the farming industry have also undergone some major changes thanks to the surge in popularity of small-batch brews. Craft beer uses more key ingredients per batch than their large, national competitors. According to a report from the U.S. Department of Agriculture, the average craft beer uses 3-7 times as much malt per barrel as a mass market beer. In addition to malt, which comes from barley, the demand for hops to brew IPAs has increased dramatically.
