A 10 minute crash course in brewing beer.
Note: most strains of yeast require temperatures between around 68-74 degrees. If you can't keep your beer temperature in that range, you risk the yeast not behaving normally. Some lager yeasts thrive in a much lower temperature, and some belgian strains need the heat cranked up into the 80s, but most standard styles need to be kept within that range.
You Brew You strongly recommends using Wyeast brand liquid yeast. It's by far the easiest and most convenient option. If you're using dry yeast, skip to 3b.Much like Franzia bags at college parties (so I’m told), Wyeast bags first require a good slap. Feel the bag and locate the inner pouch, give it a good smack (or two), shake it up and listen to make sure it’s started fizzing. Then set the bag aside and watch as it expands over the next few hours. By the time you’re ready to the yeast the bag will have ballooned up and be ready to go.
