If you have a 5.0-gallon (19-L) brewery, but want to generate 15 gallons (57 L) of beer quickly — perhaps for a party — here’s one way to do it. Normally, this would require three separate brew days. However, with the method I described here, you can do it in two brew days — and only have to make one yeast starter.

The drawbacks are that the two brew days need to be back to back, all 15 gallons (57 L) will be of the same kind of beer, and the beer can’t be over 13 °Plato (OG 1.052). Also, you will want to consume the beer fairly quickly (within a couple months), as it will go stale faster than normal homebrew. This method is best for generating 15 gallons (57 L) of beer for a party.
