Yeast was ignored for the longest time until Louis Pasteur laid the smack down with his scientific research to prove that fermentation in beer was the role of yeast in beer…

In 1516 the famous Reinheitsgebot or Bavarian Beer Purity Law restricted the ingredients of beer to malt, hops and water…

By 1860, when Louis Pasteur proved that yeast was fermenting the beer and adding fresh yeast would prevent many diseases in beer, then the Reinheitsgebot law was amended to include yeast in the ingredients.

Now, what’s needed for brewers to know about yeast is the different types of yeast available and when to use each one.

The different types is an easy topic to cover, which one to use not so much…

The first distinction I will make when it comes to yeast is separating ale yeast and lager yeasts. The most common distinction made by most brewers is that ale yeast are top fermenting and lager yeast are bottom fermenting. That is true for the most part, but some ale yeast is bottom fermenting.

What really separate ale yeast from lager yeast is that lager yeast will ferment a sugar known as raffinose and that’s what really separates the different species of yeast.

The next way to categorize yeast is whether it’s dry yeast or liquid yeast.

Liquid yeast has proved to be superior to dry yeast in many aspects so I will not cover dry yeast in great depth. The way dry yeast is processed it reduces the quality of the yeast, not to mention there are not nearly as many different strains of yeasts compared to liquid yeast strains.

Simply stated, using liquid yeast is like growing organic ingredients and using them while they are most fresh.

There are two main companies that provide most strains of yeast, whitelabs and wyeast.

Eventhough they have several yeast strains which are supposed to be the same strain, there is a bit of difference because of the way the yeast is cultured and kept.

In fact, once you use the yeast to brew a beer and wish to re-use it, the yeast will develop to a new type of strain on its own. So if you buy a weizen strain from these two companies you’ll notice a slight difference even though they share many characteristics. With that being said, here’s a list of some of the most popular home brewing strains and I’ll be posting more resources over time…

      Hey Jorge, If you were brewing several different ales, from a blonde to a amber to a porter and wanted to use just one yeast for all, which yeast would you choose ?

      • Jorge

        It’s really up to your preference… if you want a clean American style blonde, porter and amber then try Wyeast 1056 or WLP 001… if you want something more fruity, then try Wyeast 1272 or WLP060…
