GY016 : ALTSTADT ALE
Attenuation Medium Gravity* 77% – 81%
Attenuation High Gravity* 51% – 54% (6.7% – 7.3% ABV)
Temperature Range† 55˚F – 68˚F
Description: An ale yeast that ferments at cold temperatures and produces a lager like ale style with a hint of fruity esters. Leaves a slight residual maltiness perfect for traditional Kölsch and Alt styles.
Representative Styles: Kölsch, California Common, Altbier, Biere De Garde, Cream Ale
* Attenuation was measured after 8 days with Ale yeast at 70˚F and Lager yeast at 50˚F. Medium Gravity is 14˚ – 16˚Plato. High Gravity is 23˚- 25˚Plato.
† The working temperature range represents the range at which fermentation for a given strain produces a typical attenuation- not necessarily the ideal temperature for your particular beer style. As a rule of thumb, start ale yeast fermentation at 68˚ – 72˚F and then lower or raise temp as desired. Lager Yeast are typically fermented at 45˚ – 58˚F. If desired, Lager Yeast can be given a “hot start” at 65-68˚F and then lowered to the primary temperature after active fermentation begins (10-20hrs).
