Homebrewing

Homebrewing typically refers to the brewing of beer on a very small scale, as a hobby.

A typical batch of homebrewed beer is 5 gallons in size (roughly enough for 2 cases - or 48 12-ounce bottles - of beer), and is produced by boiling malt extract and hops together in a large kettle, then cooling the mixture - called wort - and adding yeast for fermenting.

Advanced homebrewers often prefer to brew "all-grain" batches of beer, by mashing the grain themselves to produce the malt starches needed by the yeast. Such techniques allow a greater control over the final quality of the beer than malt extract brewing.
