Some Quick Brewery Stats:
Here at CRBC we run a fully electric 2BBL brewing system built by Stout Tanks out of Portland, OR. It’s a standard 3-vessel brewery setup with a HLT (Hot Liquor Tank), Mash Tun, and Boil Kettle – with both the HLT and BK powered by three 5500-watt stainless steel elements…each! That makes for a bit of power (about 16,500 watts at full power) helping to heat water, but when you’re trying to bring 80Gal of wort to a boil you want that kind of power!
HLT & Mash
80-Gal Capacity each (to the brim)
x3 5500-Watt Elements in HLT
HERMS Recirculation System in HLT
Mash Tun holds about ~170lbs of grain & water at max capacity (using 1.8qts per lb ratios)
HERMS output in Mash Tun also acts as the Sparge Arm during run-off.
90-Gal Capacity (to the brim)
x3 5500-Watt Elements
Runs a constant whirlpool during boil (through tangential inlet)
Typical boil size is ~78-Gal to keep enough space for foam & boil-over protection
Designed & Built by Colorado Brewing Systems in Ft. Collins
x3 PID Temperate Readouts/Controls for the vessels
x2 Pump controls – HERMS Pump & Secondary Brewery Pump
Interlocked System – Meaning only heating one vessel (BK or HLT) at a time
From a malt & hops standpoint, we use only British base malt (Maris Otter, Golden Promise, etc.) in all of our brews – and for our hops we use many of the classic English hops (East Kent Goldings, Challenger, Fuggles, Northdown, etc.) to keep the flavor profile authentic. We do still play with other malts, hops, sugars and such to create new and interesting flavors in our beers, but the focus is always a malt-first mindset with a balanced, easy drinking pint as the end result.
Fermentors & The Brite Tank
At the moment we have x3 2-BBL Glycol-Jacketed Conical Fermentors (from Stout Tanks) to handle our our fermentations. The Glycol Jacket control system was also built by Colorado Brewing Systems, and has the capacity to run 5 individual units or zones. The glycol system is a custom built circuit system put together by our head brewer and powered by a Perlick Power-Pak. The glycol itself stays at ~24F to help maintain proper cooling for our fermentors – especially critical during our warm Colorado summers.
The Brite Tank lives in our walk-in cooler and is a single-walled Brite with a capacity of 68-Gal (to the brim – which is never reached for carbonation physics reasons). We utilize this tank to handle all our carbonation for the finished beer, as well as the fining/clarifying of the beer. The carbonation stone inside the tank has the beer fully carbonated within 24-hours, but we like to the give the clarifying process at least 48-hours before racking off to the final kegs.
Kegs & Taps
All of our beer is served from 1/2-BBL stainless steel kegs at the moment. Our taps you see behind the bar in the taproom run through the wall and directly into the walk-in cooler – making for a nice short beer-line run with far fewer temperature issues/fluctuations. Each tap is also individually controlled by its own CO2 Pressure Regulator, so we can adjust for different styles on each line.
If you’re in visiting the Taproom and have other questions regarding our brewery system, please feel free to ask one of our bartenders and they’ll be happy to answer!
