I've brewed 80 or 85 gallons. I don't have my notes here, but I've brewed 14 batches. Two were 10 gallons for sure... There might have been one more ten gallon batch. The plan was to brew 30 batches this year, but I took 2 1/2 months off in the spring to get some graduate school work completed. I did my best to get back on pace in July, but we will come up short. I will be shooting for 25 now.
