I actually brewed every night for a week after work once just to see if I could do it along with the 50Gal of brew needing to get trucked to NJ for an event (which was a smash hit with my beer!).
I was brewing the same 2 beers that week..2 10Gal batches of an IPA and 3 10 Gal of my house blonde.
It was a LOONG week. I got home about 5:30pm and was brewing until around 11pm. After post-brew clean-up, I was in bed by 1am. It was certainly a learning experience and by Friday nights brew session, I was dead on my feet but I had an absolute blast doing it as my family and neighbors all came over to help..it became sort of a "thing" in the neighborhood that week. lol
It also gave me the confidence that if I ever did go pro on a small scale level, I could brew 2-3 times a week after work without a problem.
