How to tell a nanobrewery from a microbrewery. 

As part of this month’s feature on craft brewing in Kansas City, here’s a breakdown of the types of breweries, by size and mission.

Nanobrewery // No official definition exists for nanobreweries as an industry standard. A nanobrewery, such as Green Room Burgers & Beer in Westport, is commonly defined by the size of its brewing system—typically one to four barrels in production capacity—rather than annual volume of beer produced.

Brewpub  // A restaurant-brewery that sells 25 percent or more of its beer on site. The beer is brewed primarily for sale in the restaurant and bar. Local examples include 75th Street Brewery and McCoy’s Public House.

Microbrewery  // The Brewers Association defines a microbrewery—Kansas City Bier Company or Torn Label Brewing, for example—as one that produces fewer than 15,000 barrels of beer annually with 75 percent or more of its beer sold off-site.

Regional craft brewery  // Boulevard Brewing Co. falls into the regional craft brewer category, where annual beer production of traditional and innovative beer styles runs between 15,000 and 6 million barrels.
