What's the best way to store bottle dregs in preparation of a sour ale? Can you store it in a flask with aluminum foil covering the top like a starter? Should you use a rubber stopper with airlock? I was thinking just throwing a bit of wort from a batch before hoping but boiling it for a bit, then cooling, and then throwing in dregs. Good? Bad? What's the best way to store it? I'm guessing I'll store the dregs in whatever container for about a months to two.
Thanks!
