Did my first double brew day, making two batches back to back. Took about four hours and went without a hitch. Of course, I made the same recipe because I like it and want..no need some more.
This got me to 100 gallons for the calendar year!! Just had to pat myself on the back. Thanks to the forum I've kept interest in the hobby long enough to make more than 3 batches and give it up for three+ years.
