Vin blanc
White wine glasses vary enormously in size and shape, from the delicately tapered Champagne flute, to the wide and shallow glasses used to drink Chardonnay. Different shaped glasses are used to accentuate the unique characteristics of different styles of wine. Wide-mouthed glasses function similarly to red wine glasses discussed above, promoting rapid oxidation which alters the flavor of the wine. White wines which are best served slightly oxidized are generally full-flavored wines, such as oaked chardonnay. For lighter, fresher styles of white wine, oxidation is less desirable as it is seen to mask the delicate nuances of the wine. To preserve a crisp, clean flavor, many white wine glasses will have a smaller mouth, which reduces surface area and in turn, the rate of oxidization. In the case of sparkling wine, such as Champagne or Asti, an even smaller mouth is used to keep the wine sparkling longer in the glass.
