Yet again I've chosen one of those topics which could go on for weeks and plenty of people will have an opinion.
Ages ago we did a class with a big manufacturer of magnificent glasses and it involved tasting exactly the same wine out of a whole heap of different receptacles, and yep you'd be amazed how different it is.
Now this company was saying this glass was designed and should be used for that variety of wine, you need to do the course to draw your own conclusion.
However I firmly believe wine tastes better out of glass, yep airlines I know, but hey the wine you get in economy speaks for itself, even in a plastic cup.
