I have never made wine from a kit. I would assume the directions are going to be the way you should prepare it. I have never oxygenated any of my wines I have done. Of course I start out with some wines in a bucket and for the first 5 days or so I mix it every day so that does introduce some oxygen, but really I'm trying to mix the fruit around. I have also done wine from just store bought juice, put it in a larger carboy then the amount I'm brewing, and threw an airlock on it and it has had no problems. If the directions dont call for oxygenating, I personally wouldn't do it.
