Hey guys, I’ve decided that I want to purge oxygen out of my beer when I dry hop and transfer. I don’t keg, so I don’t have CO2 tanks/pressure valves, etc… I was thinking about buying one of those Co2 “guns”, armed with cartridges ($25 at the LHBS). However, after talking to the LHBS guy, he suggested adding a little bit of DME (boiled in water and cooled) to the beer, effectively using all O2 and adding to my Co2 blanket.
The logic seems solid to me, any experience?
Just add the hops. The nucleation sites and agitation will knock some CO2 out of solution and purge the headspace.
That seems a lot simpler, yet contrary to some of the stuff I’ve read. However, I’m going to do that right now (Heck, I’ve been doing it for 10 years)…
What about dry hopping before transfer? As long as there is living yeast in the beer the oxygen will be consumed by the yeast.
