All this talk about Oktoberfest / Festbier motivated me to brew up 10 gallons.
Here is the grain bill for this Festbier:
16 lbs Weyermann floor malted Bohemian Pils
4 lbs Ireks Vienna
4 lbs Ireks Munich
The OG came in at 1.071, Brix 17.2
My recipe calculator predicted OG of 1.056.
Triple step infusion mash, with a 30 minute rest at 122, 20 minutes at 148, 20 minutes at 156, and mash out at 170.
Any idea what happened?
