Extract to All-Grain

Five-gallon (19-L) batches have long been the standard for homebrewers, but there are some real advantages to brewing smaller all-grain batches. Whether as your primary system or to use as a “pilot” system, brewing batches of a gallon (3.8 L) or so requires little space and encourages experimentation with minimal risk.

Homebrewers have been known to fret over their brewhouse efficiency numbers. Make sure you know the differences, the variables involved, and how to troubleshoot.
