I once saw something I'd like to try in regards to wine tasting--I think it was at a vineyard tour on Fine Living TV. To help taste the wine, they had pieces of something sweet, something salty, something tart, and something bitter. The only one I can remember is apple. It doesn't have to be from this particular episode, but does anyone know how this is done? It's not really about getting foods that "go" with wine, but how to train your pallate to taste the different nuances of how different tastes can effect wine. I want to try this--any ideas?
