7 BBL Brewhouse Brewing Process

Figure 1 depicts the typical brewing process stages occurring within 7 BBL brewhouse equipment:

Milling – The whole malted barley grains are cracked open by roller mills to access starch.

Mashing – The milled grain is mixed with hot water in the mash tun and held at 150-155°F to convert starch into fermentable sugar.

Lautering – The sugar rich wort is drained from the grains in the lauter tun and sparged to extract more.

Boiling – The wort moves to the brew kettle and boils for 60-90 minutes with hop additions.

Whirlpooling – The hot wort spins to settle out hops and proteins after boiling.

Cooling – The clear wort passes through a plate heat exchanger to quickly drop temperature.

Fermenting – Yeast is added to cooled wort in fermenters and beer is produced.

Maturing – Beer clarifies and flavors meld during 1-4 weeks of cold storage.

Packaging – Finished beer moves to serving tanks, kegs, or cans.

Automated systems handle transferring liquids, turning equipment on and off, monitoring times and temperatures. Brewers oversee the process via touchscreen interfaces.

Additional FAQs About 7 BBL Brewhouse Systems

1) What brewhouse configuration is best at the 7 BBL scale: 2-vessel or 3-vessel?

• For most brewpubs/taprooms, a 2-vessel (MLT + Kettle/Whirlpool combo) balances capex and throughput. If you plan 2–3 turns/day regularly or high wheat/adjunct recipes, a 3-vessel (Mash, Lauter, Kettle/Whirlpool) improves lauter speed and repeatability.

2) How should I size hot and cold liquor tanks for a 7 BBL brewhouse?

• Commonly HLT = 1.2–1.5× brewhouse size (per turn) and CLT sized for at least a double knockout, adjusted for groundwater temperature and glycol capacity. This avoids chilling bottlenecks and supports multi-turn days.

3) What utilities are often underestimated when installing 7 BBL Brewhouse Systems?

• Steam demand (boiler HP and venting), electrical service for pumps/elements/VFDs, floor drains and trenching slope, make-up water conditioning (softening/RO), and adequate glycol tonnage with insulated headers.

4) Which QA instruments deliver the best ROI at this size?

• Handheld or inline DO at brite/pack, calibrated pH/temperature probes, density/ABV meter, dissolved CO2 meter, and a microscope/hemocytometer for yeast management. These tighten consistency and reduce returns.

5) What realistic annual output can a 7 BBL system support?

• With 1–2 brewers and moderate automation, 500–1,000 bbl/year is typical. Hitting the upper end requires good cellar capacity, CLT/knockout performance, and tight scheduling.
