Many home breweries are mere steps away from being commercial nanobreweries. Five-gallon home breweries can be made into nanobreweries, although a working capacity of at least 10 gallons (37.9 L) is recommended. Fifty-five gallon kettles can be used for larger nanobreweries that have a working capacity of one US barrel (about 31.5 gallons).

If you have plans to start a commercial nanobrewery or even a production brewery with a bottling line, it can be smart to use a large homebrew rig as the initial commercial system. And, when it’s approved, it will magically become a nanobrewery. It is true that nanobreweries often can’t produce enough beer to turn a profit that one can live off, and you won’t be distributing pallets of beer far and wide, but you can expand later and fulfill those dreams, or be happy brewing great local beer on your cool nanobrewery system!
