These lager strains have been carefully cultivated and selected to meet the unique demands of lager production, offering a wide spectrum of flavors and aromas, making them indispensable tools for brewers. Whether you are a seasoned brewmaster or a novice homebrewer, Fermentis lager strains are a key ingredient in achieving the finest and most consistent lager beers.

SafLager™ W34-70

The strong & robust lager yeast, ideal for neutral beers

This famous brewer’s yeast strain from Weihenstephan in Germany is used world-wide within the brewing industry. SafLager™ W-34/70 allows the brewing of beers with a good balance of floral and fruity aromas and gives clean Flavors and high drinkable beers.

SafLager™ S-189

A great yeast for elegant lagers with floral notes

Originating from the Hürlimann brewery in Switzerland. This lager yeast strain’s profile allows to brew fairly neutral flavor beers with a high drinkability. Depending on the conditions, it tends to present noticeable herbal and floral notes to lager beers.

SafLager™ S-23

The solution for fruity and hoppy lagers

Bottom fermenting brewer’s yeast originating from Berlin in Germany. SafLager S-23 recommended for the production of fruitier and more estery lagers. Its profile gives beers with a good length on the palate.

SafBrew LD 20

An All-In-1™ yeast & enzyme blend for lower carb* dry Lager beers

SafBrew™ LD-20 is the perfect choice for the production of very dry and neutral lager beers with reduced residual sugars. SafBrew™ LD-20 is made of both active dry yeast and enzymes and allows the production of beers containing the same level of alcohol with a reduction of up to 20% of carbohydrates including dextrins.

Applied research conducted by Fermentis

To help brewers choose the best yeast for their beers, we started a program called Make Your Choice (the MYC Program) a few years ago. The aim of the program is to guide and inform our customers about the benefits of our yeasts, especially the flavor expressions. It all began with Baseline Flavor & Aromas, a sensory study conducted in a standard condition that mapped the position and representations of all of our beer yeast according to three important fermentation flavor profiles: their fruity, spicy or neutral characters. The second step of the MYC Program consisted of a deeper characterization of each yeast under different fermentation conditions.

With broader technical and organoleptic information, we provide brewers all they need to know about the SafLager™ W-34/70 fermentation behavior and its detailed sensory expression. This is refined information that supports the best and right choice for lager fermentation, in which we evaluate how the parameters (such as wort density, fermentation temperature and pitching rate) could change the neutral fermentation profile of this specific yeast. From the various studied conditions (six are represented below), we obtained a matrix that help us characterize what happens when we change a specific variable.
