Current practice is to stir a couple times a day. I actually stir rather vigorously, releasing CO2 and incorporating oxygen, hopefully.So, the yeast neeeds oxygen in the first stage..... should the primary fermentation be stired everyday? This need for oxygen rules out using jugs with narrow necks for the primary fermentation; is that correct?
Rules out jugs? Not necessarily. I don't really know how much oxygen yeast need. I believe it's mostly needed while they're multiplying. Many wine makers over the years went straight to an airlocked vessel with, apparently, no problems. Personally, I know the open (but cloth covered) vessel works so I'll continue to do that until I have reason not to.
