- Oxidation is my #1 enemy, but that beer still goes down smooth if I throw some grapefruit juice in the glass with it.
- Kegging in a one gallon keg is easy and lets me drink my beer almost immediately. I also seem to get a lot less oxidation this way.
If you're looking for fairly extreme oxygen protection, you can do what I do (
if you have a fermenter with a spigot, this wouldn't work with most racking canes) which is to:
- purge a keg, and fill it with a few psi of CO2
- rig a gas ball lock to a few feet of tubing that can fit inside the neck of an airlock - not the S-type
- rig a liquid ball lock to tubing which will fit onto your spigot
- hook up both connectors at the same time, so they're both CO2 purged (I partially engage each so I can do them one at a time, that works too)
- place the gas tube into the neck of your fermenter, which, of course, is virtually oxygen-free, and the liquid tube onto your spigot, and gravity rack (though an inline transfer pump would also be fine)
The beer flowing into your keg will push the CO2 in the keg through the tubing and into your fermenter, blanketing your beer, meaning you have a virtually flawless transfer. This is essentially a closed transfer, but it's not conducted under pressure, and I doubt purging the tubing would be so crucial if you had a larger volume of beer to work with, so I figured I'd call it out as opposed to just saying "do a closed transfer."
Or, ferment in a keg with a spunding valve, and transfer under pressure! I'm nervous about getting kegs that dirty, or rather I don't like to deep-clean kegs often and I feel like you'd have to if fermenting in them, but that's probably a marginally better option if you're willing to do it.
If you knew all this, my apologies, and hey, someone probably didn't!
