I am some what new to home brewing. Not the drinking part, just the brewing. I started with the Mr. Beer kit years ago, & now have upgraded to bigger & better. I have a easy ?. I did my primary fermentation in a pale, & have now tranfered it in to a cornelius keg. I flushed it with co2 before the transfer. now the ?. Do i charge the keg with co2 for the secondary fermentation as it sits, & if so what psi is good. Thanks.
