I understand that a 15 bbl system is a benchmark for the break even point.
With that you would obviously need the sales to support that. There should also be a plan for expansion in the event that the brewery sales increase beyond normal production levels.
This is a silly idea. While you can't run a less-than-15 bbl production brewery forever you can certainly start smaller and increase the size as possible. Seven barrels seems like a nice number for in house (non production) and I've seen a multitude of 10 bbl breweries make it just fine as production breweries. All of those 10 bbl brewers (who are now big breweries) would advise against starting with the smaller system, but they don't recognize that they would have never made it with the increased costs of the larger systems. Otherwise I agree with everything you said. cheers, j
