Rough math but I think that is about 100 12 ounce bottles. I would say that sometimes happens for me but I average about half that in a month.
Yeah, that's about what it is. For me that's two 10G batches a month. I don't drink it all myself and there is a little waste and it's usually closer to 15G a month for me, but some months the beer runs out a lot faster than I expect. Either my 11year old has started drinking or I had more than I thought.
