requirements re oxygen vs growth. It ain't much.
- Andrew, thanks for that info about the air pumps.

- I use an airstone running off an oxy-acetylene welding torch, to introduce
oxygen to the wood-aging process, and sometimes for boosting the yeast-
It may not be the most efficient way, but I already HAVE the oxyacetylene
gear, and it's within a torch-hose length of my brewing area.
Works great for me.
