I cold crash the beer first and sometimes transfer it to a clean fermenter which now becomes a bright tank. Within 24 hours the beer reaches 37° using either a cooler or ice bath. By adding CO2 to the tank slowly, just a couple pounds at a time you allow for a quicker and more efficient absorption of CO2. Here's a trick I learned from Rande Reed, head brewer for Snoqualmie Falls Brewing. Most small brewers don't have access to a Zahm meter or a good way to test the CO2 volume. By slowly bringing the pressure to 15 lbs on the tank and holding it there, I am able to achieve 2.5 volumes of CO2 very consistently. 15 psi was the number that was determined after testing using Rande's method on his 7 bbl bright tanks and applying it to the 1/2 bbl Sabco vessels. Introduce the CO2 slowly, reaching 15 psi and then slowly purging CO2 from the top as it is entering the bottom, I am able to precisely carbonate 7 bbl of beer in a few hours. When taking this to a 1/2 bbl level, keep the CO2 pressure at 5 psi rather than allowing the top to bleed it all out. All beer can be carbonated correctly and ready to keg within 24 hours. Cheers, SteveTwo options are available. The coupler thread option includes the gasket for the threaded nut. The tri-clamp option does not include a 1/2" tri-clamp gasket or clamp.
The Dirty Gauge was invented by Steve Acord at Dirty Bucket Brewing Company in Woodinville, WA. This brilliant product accurately reads pressure during the carbonation process. You can attach the Dirty Gauge directly to the top of your Sabco Fermenter. Use this in conjunction with our carbonation stone and speed up the process considerably. Here is a summary from the inventor, Steve Acord:
Brewer hose with tri-clamp fittings included. Don't purchase them all separately like some sort of fool. This hose is 5 feet long and allows you to make a quick, sanitary connection between tri-clamp components. We pre-assemble everything for you with brewer hose, tri-clamp ferrules, stainless steel hose clamps, tri-clamps and gaskets. You'll save money by buying these components as a kit.
