Hi All, Onto my second ever batch, first one being a lager and tasting ok. This time trying a Coopers Pale ale. I use an internal heater (fish tank style) to moderate my temp at around 22 degrees. On my first brew I only left it in the barrel for around a week before bottling, it appeared all fermentation had ceased (no bubbling). Since jumping on the forums I have noticed most advice suggests that I leave it in the barrel for closer to 2-3 weeks? Is this correct? And if so, do I leave the heater on at the same temp the whole time or after it stops bubbling do I turn the heater off and just let it sit. Cheers.
