What do you all use out there for "oxygenating" the brew prior to adding the yeast in the FV?
Do you just shake it all up to get it all frothy or do you pump oxygen / air through it?
I'm interested as, until now, I have been just agitating the wort as you do, but now I am thinking of getting some oxygen - in a small cylinder - to bubble through the wort.
I have thought of using a fish tank bubbler with a suitable brass "stone" to do the job but the the question of sanitation arises. The air is drawn through the base of the pump with just a simple felt filter, which could be sanitised before use of course, but would this be enough to avoid any infection?
Oxygen gas comes in several forms of course, from the small canisters on Amazon that seem to have only a few puffs in them (5L or 10L) to larger bottles used for welding kits (these are not for Medical use- as stated on the canisters) to the various sizes of Medical quality Oxygen cylinders and bottles. The later ones seem to have restrictions on the purchase here (maybe that is a UK thing, I don't know) and they are expensive to not only buy but to cobble together the other necessary parts such as regulators to adjust the flow etc.
Any recommendations as to the best way to go - this may help others out there with similar intentions.
