He said "a 15 barrel brewery can turn out 30000 barrels a year". That would be 2000 batches per year, 5.5 batches per day working every day. I think he must have misspoken and meant 3000 barrels, which would be 200 batches per year. He then said a 3 bbl system can produce 750 barrels per year which would be 250 batches per year. That would be 5 batches per week.
