after the last 4 or 5 brews they all have a common off flavor. Best described as "cereal" or "grain like" I just cant places it, all have been varying styles with malts from different maltsters and different yeasts. I tried to narrow it down by doing a simple SMaSH and it still has the same flavor. I've been over my notes and haven't found a single variable that is repeated that would cause this sort of off flavor. Differing grain crushes, different mash temps, cooling lengths, fermentations temps, fermentation time. Nothing sticks out and says AH-HA. anyone have any ideas? BIAB method, the only real change is I upgraded to a Spike CF 10.
