A strain for the traditional top-fermenting style from Düsseldorf. Alt was considered the "old" style from before the advent of bottom-fermenting lager yeasts. This top cropping yeast strain from Germany with clean flavor profile and broad fermentation range. Beers mature rapidly, even when cold fermentation is used. Low or no detectable diacetyl.

*NOTE:*During summer months, we include complimentary ice packs with all liquid yeast orders. However, it is difficult to guarantee that the ice packs will stay frozen given transit times and particularly hot temperatures. For this reason, we recommend ordering dry yeast during summer months.
