While waiting for his brew pot to heat up to 150 degrees, Sam Fogel pours roasted barley seeds into a grain bag, made of a fine mesh like cheesecloth.
The grain bag steeps like tea for 20 minutes and the temperature must stay about 150 degrees. After the grain bag comes out, the brew is called “wort."
After bringing the wort to a boil, Fogel adds syrupy malt extract.
Fogel uses prepackaged hops for this recipe because he is going for a German-style lager. The hops are added to the boiling wort.
The wort must be cooled quickly and then poured into the 5-gallon fermenter.
A hydrometer can be used to help calculate the alcohol content.
After the yeast goes in, the lid and airlock are secured. Let the fermentation begin!
