Just checked on my Abdij after exactly 1 week in the FV. It had an OG of 1068 (I think I added a bit to much water, maybe about 10 litres instead of 9, but I added a bit more sugar than Brewferm specified to get it as close to the 1.070 target OG), and it's now down to about 1.012, having been at a near-constant 20 degrees C. In the trial jar it looks a little fizzy, so I'm porbably going to leave it at least one more week at 20 degrees, maybe two, to make sure it's finished. Had a cheeky little taste from the trial jar and...wow! I'd drink it all right now! How I'm going to last 6 months of conditioning is beyond me. A real test of patience and self-discipline!
In the meantime, I'm anxious to get my next brew going, so here is my question. I have two demijohns sitting doing nothing, so can I transfer the Abdij into them, with airlocks to finish the fermentation, and get my next brew going in my main FV? If so, should I transfer a little of the trub from the FV into the demijohns, or should I avoid that at all costs? Or could I leave the trub in the FV and start my next brew on top of it?
