Has anyone done any side by side bench tests to compare the effects of oxygen during primary fermentation of meads? It's my understanding that yeast need oxygen during the first few days (at least) of fermentation, though beyond that it seems to be very much a matter of opinion. There is the 1/3 sugar break theory, which resonates with me, though my own method, at present, involves stirring all the way to the 2/3 sugar break, when I transfer to secondary. Now, I'm talking about a vigorous stirring, as opposed to a gentle stir or a mere punching down.
Am I perhaps overdoing the stirring/oxygenation? Would I be better served stopping the vigorous stirring at the 1/3 break? If it has any bearing, I am referring to the fermentation of pretty high gravity (14-15% abv) cysers and melomels, which are very well fed. They are turning out pretty well, but they could always be better, I suppose! Thanks -
