You can produce 1000 beers a day with this setup.
Lets see, 340 ml bottle x 1000 = 340 litres/day
Yesterday I ran my 30 gallon kettle with a batch and got 80 litres finished, so I'd need to run about 4 batches a day to get my 1000 beers a day... so if you were to run 8 batches a day with his gear...
Maybe they're 1000 really, really small beers.
