Like many companies that wrangle our microbial friends, White Labs has temporary or “seasonal” offerings. Called “Vault Strains,” these microorganisms are released for a short while, then back in the vault for another million years! (Or however many years White Labs decides.)
About this strain they write:
A Swiss-style lager yeast that with proper care can be used to produce lagers over 11% ABV. Sulfur and diacetyl production is minimal.
WLP885 Zurich Lager Yeast is POF+, this strain will contribute phenolic characteristics to finished products.
