Fermentis W34-70 Saflager Dry Ale Yeast Brick - 500g
There are two types of yeasts used in making beer: ale and lager yeasts. Lager yeasts are bottom fermenters. This means that the yeast prefers to ferment starting at the bottom. The final flavour of the beer depends on the temperature the lager yeast is fermented as well as the type of lager yeast used. Lager yeasts grow less rapidly compared to ale yeasts and since the former is a bottom yeast, it produces less surface foam. As for floaties, it is a common occurrence in brewing beer especially when it is not pasteurized or filtered.
Dry lager yeast also ferments at lower temperatures compared to ale yeasts. They ferment at temperatures less than 400F to produce brews that have some ester and fruity taste in them. It can be used to create a myriad variety of beers such as lager and pilsner styles. It is packaged as a 500-gram yeast brick, perfect for making large batches of ale beer. This is especially so if the brew is adapted to casks and cylindro-conical tank fermenters.
This famous yeast strain from Weihenstephan in Germany is used world-wide within the brewing industry. Thanks to its technological properties, this strain has become the most popular strain for lager brewing and is used by industrial breweries and brewing groups around the globe.
