The best method I’ve found so far for balancing quality, cost, space required, etc. has been the Brew-in-a-Bag method. I’m finding it’s tough with high-gravity beers, around 1.060 OG is where I’ve topped out. The following video from BrewingTV is full of good info. BrewingTV stopped making videos but if you’re interested in homebrewing their YouTube channel is an incredible resource.
