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:
This northern European lager strain emphasizes clean and crisp characteristics. Malt flavors tend to be secondary, promoting clean drinkability. It is ideal for Vienna, schwarzbier or American-style lagers.
