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 yeast helps to produce a malty, yet balanced traditional Munich-style lager. Clean and a strong fermentor, it’s great for a variety of lager styles ranging from helles to rauchbier.
