It's often the same with white wine. Red wine, on the other hand, is often served too warm.
So, then, it's OK to put an ice cube in red wine, but not in white wine? I'm just trying to understand the etiquette here.
Story time ... (I have a million of 'em) ... I was at a party at Domaine Chandon, a maker of sparkling wines. It was a hot August afternoon. Robert Mondavi just happened to be at the same party. He had his minions/groupies all around him so I just ignored him. But I noticed that when a bucket of ice passed his way he grabbed a handful of the cold stuff and dropped into his red wine. All the groupies went silent, their mouths wide open as they gazed in horror at what their leader, their God, just performed. Mondavi looks up at them and says "... on hot days I like my wine like this." Ever since then I drink wine how it best tastes to me.
