How do you taste wine? reds to white ?

[Thomas]

It matters. The rule is lighter to heavier to dessert, which often means white to red, but not necessarily always.

Think of it this way: if you bombard your taste buds with heavy, complicated tastes before lighter ones, you will have overpowered the buds and made the light tastes relatively undistinguishable. As for dessert wines: dessert always comes last, thanks to all that sugar.
