I thought I would mention this especially with BJ just getting back into brewing. There was a "low oxygen" movement that started around 8-9 years ago and the bottom line is that we want to keep O2 away from our wort during the process as much as possible. The guys who came up with it were very rigid and were very scientific with their information. Most brewers don't get into this level of detail. I tried to adopt some of these things and I still do some of it including purging the keg with CO2 from the fermentation and doing closed-loop transfers from fermenter-to-keg. There are some other things too. One thing was to dose your strike water with yeast and sugar prior to heating your water. The yeast would use up the O2 in the water in as little as 20 minutes so you're starting with water that's as low in O2 as it can be (not sure of the levels). I've been doing this for years now. When I made the Vienna Lager I just posted a pic of, I was in a bit of a hurry so I skipped the yeast+sugar idea and I made a note. This Vienna Lager came out EXCELLENT and when I checked my notes I saw that it was the first batch I had made without the yeast+sugar. I think I have made another FOUR batches without the Y+S and I'm happy to skip that step going forward since it seems it wasn't doing anything for me.
