Notes

Shooting for 22 IBU (as per copying KCBC's Zoktoberfest, my fav), so adjust if necessary for competition as the bitterness is a little more assertive.

Medium (ish) body mash temp 150f. Batch sparge at 168f.

First batch: Fermented with 2nd gen 34/70 (built up with starter) at 51f. Initially chilled to 49f (mid 60s with the chiller and then in the firm tank for a few hrs to get it to 49f). Pitched at 49f, let free rise to ferm temp. Started D-rest at around 60-70% attenuation (about 5 days) raising the temp about 4F every 12 hours to 68f. let sit above 65f for 3 days. Cold crashed gradually to reduce suckback. Fined with gelatin at 35f. Packaged 24 hours later (could have used some extra time, still a bit hazy at the beginning).

Thinking of trying Omega Okboberfest lager yeast next time.

This is the best beer I've ever brewed.
