I picked "1" to appease the beer gods.
And I'm hoisting a Stone IPA as a sacrifice to their goodwill.
But I'm on batch #49, and none have been infected (knock, knock).
The "1" I claimed was a yeast harvest that grew a skin of mold, though. Poured almost a liter of thick slurry down the drain. Thought (briefly) about skimming the mold and using it anyway, but decided it wasn't worth the risk. (Was just WLP001, easily replaced)
