Well, we're going to need to know WHAT the off taste is like before we can tell you waht caused it. Walk us through your process and recipe, as detailed as you can be. For off flavors I immediately go to fermentation temps, recipe, steeping temps, pitching rate, and water, in that order.
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I own!
