Y is for Yeast
Yeast. That magical organism. The one that turns sugar-water into something that in this country only those over 21 years of age can drink.
But not all yeast is created equal. The yeast you use for baking bread won’t give you the beer you expect, though fermentation may occur. And, perhaps more surprisingly, the yeast that is used to brew a lager is not the same as a yeast that makes a good ale. And if you have a high gravity wort, you’ll need a totally different type of yeast. And let’s not get into what you might need for wine or champagne.
Brewing yeasts are all different strains of the yeast Saccharomyces cerevisiae. Some strains are better at fermentation under cooler conditions are are used for brewing lagers. Others like the heat and are used to make ales.
And you can do crazy things, like use an ale yeast at cool temperatures, or a lager yeast at warm temperatures, and you’ll get totally different tasting beers.
Each yeast strain imparts a different character to the beer it ferments. Go stand in the yeast section of your local home brewing shop to see the possibilities!
I’m participating in the April A to Z Blogging Challenge. The goal is to write a post prompted by a letter of the alphabet on each day of April (except Sunday). My theme this year is brewing. Visit my other A to Z posts by clicking here.
