Frequently Asked Questions

Q: What is the brewhouse capacity needed for packaging 5000 barrels of beer annually?

A: To package 5000 barrels (BBLs) per year, a brewhouse capacity of around 10-15 BBL is recommended, assuming 1-2 brews per day on average to account for fermentation, filtering, storage and packaging time. So a 10 BBL or 15 BBL system could support 5000 BBL annual packaged output.

Q: What size boiler system is needed to power a 5BBL brewhouse?

A: A good benchmark is a 20 bhp (boiler horsepower) steam boiler system for powering the mash tuns, brew kettles and other heating operations of a 5 BBL brewhouse. This provides sufficient steam pressure and flow rates to quickly heat water and wort while matching the brewhouse capacity.

Q: How much floor space should I budget for a new 5 BBL brewhouse and associated utilities?

A: Ideally plan for 1500 – 2500 square feet for the 5 BBL brewhouse system including boiler room, glycol tanks, fermentation tanks and packaging area. This allows comfortable space for operations, cleaning and maintenance access around all vessels.

Q: What is the difference between 2-vessel, 3-vessel and 4-vessel brewhouse configurations?

A: 2-vessel are the simplest, with just a combined mash/lauter tun and brewkettle. 3-vessel separates the mash tun and lauter tun for greater efficiency and flexibility. 4-vessel keeps these separate and adds a whirlpool tank for settling out trub post-boil prior to fermentation. Additional vessels can be added like hop back or water deaeration unit for further complexity in multi-vessel configurations.

Q: Should I choose fully automated or manual operation for 5BBL?

A: Automated operation can improve consistency and reduce direct labor requirements but costs more upfront. For maximum flexibility at start, many brewers recommend getting semi-automated equipment that only uses automation for critical boiling stage but keeps affordability for small scale. This also develops firsthand experience before adding more automation down the road.

Q: What are the options for financing new or used brewhouse equipment purchases?

A: Beyond self-funding, options like equipment leasing, SBA small business loans and craft brewery specific financing from companies like Encore Finance group allow spreading out the capital investment over longer terms. Used equipment bought from other breweries also reduces initial purchase costs but may incur higher lifetime maintenance charges.
