I am aware, as I am sure you are, that the generally accepted advice is to use a bottle filler and fill from the bottom up to avoid injecting oxygen. Nevertheless, I always bottle from the spigot--guess I am just lazy. I tilt the bottle and let the wine run down the side of the bottle and avoid most bubbles and vigorous aeration. The last bottle or so are filled using a funnel and get a lot of aeration. I haven't been able to discern any negative effects using my non-standard procedures. I am not encouraging you to do the same, just letting you know what my somewhat limited experience has been.
