Thank you to John and L. Paul!

L. Paul: I don't understand your logic that a quality wine with a screw top doesn't need decanting. As for the perspective of the decanter's top, I don't have the issue that you mentioned for this particular photo though I have experienced it with at least one other photo that we discussed; the "lower" rim of the decanter is clearly behind the pour and the "upper" rim is clearly in front of it to my eyes. And by the way, the residual wine left in the decanter is never wasted; I drink the wine directly from the decanter.
