Temperature Range: 60-70F, 15-22C
Alcohol Tolerance: 10% ABV

WYeast 1968 - London ESB Ale
This extremely flocculent yeast produces distinctly malty beers. Attenuation levels are typically less than most other yeast strains making for a slightly sweeter finish. Ales produced with this strain tend to be fairly fruity. Fruitiness will increase with higher fermentation temperatures (70-74F, 21-23C). Diacetyl production is noticeable and a thorough rest is necessary. Yeast traps trub easily and autolysis during storage is accelaerated. A very good cask conditioned ale strain due to rapid and complete flocculation. Brilliantly bright beers are easily achieved without any filtration.
Flocculation: Very High
Attenuation: 67-71%
Temperature Range: 64-72F, 18-22C
Alcohol Tolerance: 10% ABV

WY2206 - Bavarian Lager
Used by many German breweries to produce rich, full-bodied malty beers. Good choce for Bocks and Dopplebocks. Benefits from diacetyl rest at 58°F(14°C) for 24 hours after fermentation is complete.
Flocculation: medium-high
Attenuation: 73-77%
Temperature Range: 46-58° F (8-14° C)
Alcohol Tolerance: approximately 9% ABV

WY2247 - European Lager

Alc. Tolerance 10% ABV
Flocculation low
Attenuation 73-77%
Temp. Range 46-56°F

WYeast 2278  -  Czech Pils
Classic pilsner strain from the home of pilsners for a dry, but malty finish. The perfect choice for pilsners and all malt beers. Sulfur produced during fermentation can be reduced with warmer fermentation temperatures (58°F) and will dissipate with conditioning.
Flocculation: Medium-High
Attenuation: 70-74%
Temperature Range: 50-58F, 10-14C
Alcohol Tolerance: 9% ABV

WYeast 2308  -  Munich Lager
A unique strain, capable of producing fine lagers. Very smooth, well-rounded and full-bodied. Benefits from temperature rise for diacetyl rest at the end of primary fermentation.
Flocculation: medium
Attenuation: 70-74%
Temperature Range: 48-56° F (9-13° C)
Alcohol Tolerance: approximately 9% ABV

WYeast 3068  -  Weihenstephan Weizen
Classic German wheat beer yeast, used by more German brewers than any other strain. Dominated by banana ester production, phenols and clove-like characteristics. Extremely attenuative yeast, which produces a tart, refreshing finish. Yeast remains in suspension readily with proteinacous wheat malt. Sometimes used in conjunction with lager yeast and kraeusened to finish the beer and improve the overall dryness. High CO2 levels, typically at 2.7 - 3.2 volumes is desirable for best presentation. This strain is a true top cropping yeast requiring full fermenter headspace of 33%. Increasing pitch rates will reduce ester production. Alcohol tolerance: approximately 10% ABV
Flocculation: low
Attenuation: 73-77%
Temperature Range: 64-75° F (18-24° C)
Alcohol Tolerance: approximately 10% ABV

WY3522 - Belgian Ardennes
One of many great beer yeast to produce classic Belgian ales. Phenolics develop with increased fermentation temperatures, mild fruitiness and complex spicy character.
Flocculation: high
Attenuation: 72-76%
Temperature Range: 65-85° F
Alcohol Tolerance: approximately 12% ABV

WY3739 - Flanders Golden ale
This well balanced strain from northern Belgium will produce moderate levels of both fruity esters and spicy phenols while finishing dry with a hint of malt. A robust and versatile strain that performs nicely in a broad range of Belgian styles.
Alc. Tolerance 12% ABV
Flocculation medium-low
Attenuation 74-78%
Temperature Range 64-80°F

WYeast 3787  -  Trappist High Gravity
Produces intense esters and phenolic characteristics with complex fruitiness. Does not produce significant amount of iso-amyl acetate (banana esters) or bubble gum esters typical of many yeast of this style. Phenol and ester production are influenced by fermentation temperatures. Phenols tend to dissipate as beer matures. This type of yeast benefits from incremental feeding of sugars during fermentation, making suitable conditions for doubles and triples to ferment to dryness. True top cropping yeast with a broad temperature range.
Flocculation: Medium-High
Attenuation: 74-78%
Temperature Range: 64-78F, 18-25C
Alcohol Tolerance: 12% ABV

WYeast 3944  - Belgian Witbier
Produces a complex flavor profile with a spicy phenolic character and low ester production. Phenols tend to dominate other flavors and dissipate with age. Ferments fairly dry with a finish that compliments malted and unmalted wheat and oats. Sometimes used in conjunction with lactic acid bacteria to produces a sharper finish. This strain is a true top cropping yeast requiring full fermenter headspace.
Flocculation: Medium-Low
Attenuation: 72-76%
Temperature Range: 62-75F, 16-24C
Alcohol Tolerance: 12% ABV
