Generally, people sip slowly on dessert wines, and a 2oz pour is a normal serving size. To enhance the flavors and aromas of dessert wines, serve them in specialized port or sherry glasses. This style of dessert wine glass has a small, compact shape with a long stem and tapered rim. Ideally, you want to serve your dessert wines in crystal glasses, as the glassware refracts light and enhances the color of your wine. Serve sparkling dessert wine in a flute.
