Measuring specific gravity & calculating alchol content

Most homebrewers want to know the alcohol content of their beer, and taking specific gravity (SG) readings is the key to being able to calculate it.

Brew in a bag

BIAB is the easiest and usually cheapest way to make an all-grain beer. It is growing in popularity because it is simpler and quicker than other methods of all-grain brewing and requires only one vessel, meaning it needs less investment and less room.

Whirlpooling

If you're an all-grain or partial mash brewer, after the boil there will be a large amount of coagulated proteins and hops in the wort that you need to separate before transferring the wort to the fermenter or cooling cube.
