It was a nice day today, and my NYE beers went way too fast, so I bumped up my inventory and did 2 (5 gallon) batches of beer this afternoon. (Oatmeal Stout and a Guinness Clone)… I used my conical fermenter for the Oatmeal stout and my old glass carboy for the Guinness. My question is about the 2ed fermation of the Guinness… I do not have another 5 gallon glass container, so (as done before) I was planning to keg it out of the primary, and let the keg sit for 2 weeks… so should that be under the standard 15-20 psi to force carbonate? Should that be under for less in case there are some fermentables still in there? Should I vent it?
