How do I choose the best brewer’s yeast for beer?

Hops, which are combined with brewer’s yeast to make beer.

Brewer’s yeast for beer helps convert sugars into alcohol during the brewing process. There are many different varieties of brewer’s yeast available, each of which imparts different characteristics to beer. When choosing a brewer’s yeast for beer, you need to consider the type of beer you are making as it will be influenced by the type of yeast fermentation, the flavors the yeast imparts, the level of flocculation of the yeast and its attenuation ability. .

Yeasts with different fermentation characteristics make different types of beer. Top fermenting yeasts, for example, are those that tend to foam on the surface of the liquid during fermentation before settling. This type of brewer’s yeast usually produces ales, wheat beers and stouts. Bottom-fermenting yeasts are those that do not form a superior foam during fermentation. Brewers use this type of yeast for lagers, including Pilsners, Dortmunders and Bocks.

You should also choose a brewer’s yeast for beer based on the flavor characteristics you want to impart to the finished product. Different strains of yeast impart different flavors. Strains intended for American beers, for example, tend to produce a cleaner, slightly fruity flavor, while English beer strains tend to produce a more malty and sweeter end product. Yeast by-products provide the flavor variety and produce flavors that range from fruity to spicy to medicinal. Think about what flavors you want your beer to have and which flavors you want to avoid when choosing your yeast.

Flocculation is the ability of yeast to agglomerate and settle in beer. The type of brewer’s yeast you choose should again have flocculating qualities suited to that particular style of beer. Yeasts have this characteristic with low, medium and high capacity. Ales, for example, generally include medium to high flocculating yeasts, while lagers tend to incorporate low to medium-capacity strains.

Attenuation is the conversion of sugar to alcohol. This characteristic affects the final gravity of the beer. The lower the attenuation capacity of the yeast, the greater the gravity and the sweeter the end product. Yeast strains come in low, medium and high for this trait. The best way to choose a brewer’s yeast suitable for beer is to buy a kit, as this will include the proper yeast for that type of beer; otherwise, speak to a local brewer – hands-on experience often provides the best advice.
