Picking a brewhouse size is the decision that shapes every other choice in your brewery — cellar count, floor space, labor, and how fast you can grow. Buy too small and you'll be double-brewing seven days a week; buy too big and you've tied up capital in capacity you can't fill. Here's how to think it through before you shop for a used system.
Start with realistic annual volume
Work backwards from how much beer you actually expect to sell in years one and two — not your best-case dream number. Your brewhouse size sets the batch, and your fermentation tanks set how many batches you can have working at once.
- 7 BBL — great for a taproom-focused brewpub or a brand still finding its footing. Flexible for small batches and one-offs, but it becomes a grind once demand is steady.
- 15 BBL — the workhorse of American craft. Enough output for taproom plus modest distribution, without an industrial footprint.
- 30 BBL — for brands with real distribution or aggressive growth plans. Fewer brew days per barrel, but a bigger up-front and space commitment.
The brewhouse sets your batch size; the cellar sets your output. A 15 BBL brewhouse with ten fermenters out-produces a 30 BBL brewhouse with two.
Match the cellar to the brewhouse
A common mistake is buying a large brewhouse and starving it of fermentation. Each brew fills a fermenter for one to three weeks. If you want to brew several times a week, you need enough tanks to hold that beer through fermentation and conditioning. Plan tank count around your turns, not just your brewhouse.
If you're unsure how many tanks you need, our guide on inspecting and buying used fermenters pairs well with this one, and the catalog shows what sizes are in stock right now.
Where used equipment gives you an edge
Buying used lets you right-size affordably — and re-size later. Because used tanks and brewhouses hold their value, a brewery that buys a 15 BBL system used can often sell it on and step up to 30 BBL as demand grows, without the punishing depreciation of new gear. That flexibility is a quiet superpower for a growing brand.
