Only had roughly 4 gallons of RO water on brew day by accident. I topped the RO water off with roughly 1 gallon Meijer drinking water and .75 gallon of distilled water. To finish the water volume I topped up to 8.25 with RV filtered tap water from Bentley’s BrewerLee. PH was measured at 5.45 after the start of the 144° mash rest Calcium carbonate was added after mashing in. The recipe was for CRHC Group Brew Day at my house. I asked AI to put together a Doppelbock recipe with a list of ingredients I had on hand. AI had me coming in at 1.076-1.078 but I realized 1.058 by hydrometer and 1.056 by tilt. I let the fermenter sit over night til the next day and transferred to the rounder and added pure oxygen for 60 seconds. Pitched yeast at roughly 66°F and slowly dropped the temp to 49° over the next several hours. Fermentation Schedule: 49° F ~days 0-4 51° F - days 5-10 54° F - days 11-14 60° F - days 15-18 diacetyl rest Closed transfer to keg, then start lagering at 12 lbs CO2, at <40° F for 4-8 weeks
