Midwest Supplies

Do you already have a homebrew draft system? If so, use this "High Pressure" yeast to ferment lager beer in one week - at room temp! Ferment at room temperature (62-68F) under 1.0 bar (14.7 PSI) of pressure until final gravity is obtained, generally in one week. Lager the beer at 35F, 15 PSI, for 3-5 days, to condition. Sulfur production is strong first 2 days, then disappears by day 5. Do not need to carbonate, since beer is held under pressure at 1 bar entire time.

Kegging system required to use this yeast! Midwest recommends fermenting in a 5 gallon soda keg with a Ball Lock Adjustable Pressure Relief Valve (without an airlock) to keep the internal pressure at ~14.7 PSI. Adding Fermcap-S will help keep krausen down in the tighter space. Monitor and adjust the pressure in the keg to ~14.7 PSI (check the variable pressure relief valve gauge) 1-2 times daily. Keeping an eye on it will prevent excessive pressure build-up and overcarbonated beer. The Ball Lock Adjustable Pressure Valve without Gauge may also be used to bleed off excess pressure from fermentation. You will need to find the specific internal pressure with a CO2 tank regulator or Bleeder Valve Assembly (does not have variable pressure relief valve).
