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 produces a beer that is malty and well balanced. Expect toasty flavors with malt-driven esters. Highly flocculent and a good choice for English-style pale ales, brown ales, and milds.
