When serving your guests wine, it is important to serve it in a white wine glass rather than in wine glasses that are made for red wines. Typically, white wines are seen as having lighter, fruiter flavors and require a tulip shaped glass with a narrowing rim in order to release the bouquet, or aroma of the grapes. If the glass’ bowl is too wide, too much oxygen will reach the wine and make it taste bland.
The narrow bowl on white wine glasses also helps maintain the proper serving temperature. White wines are meant to be served around 38 to 50 °F to properly release the flavors of different varietals such as chardonnay, white Zinfandel and Sauvignon blanc. If your whites are stored at room temperature, the easiest way to achieve the proper serving temperature is to put the bottles in the refrigerator for about two hours before serving. Many wine experts recommend a wine glass with a narrower bowl and rim for young and crisp white wine in order to direct the sweet flavors of the wine to the front of the tongue then to the side of the tongue for more sensitivity to the acidity in the wine. While fuller bodied and more mature white wines are typically served in a glass with a wider body and opening, but the wine glass is still designed to be narrower than that of red wines. The lips of these wine glasses tend to curve inward, rather than outward like glasses for younger whites in order to let the more complex aromas of mature wine fully bloom in the glass.
White wine glasses also come with or without a stem. Although stemless glasses are a growing trend in fine dining restaurants, wine enthusiasts generally recommend that you only use a stemmed glass, and never hold the glass by the bowl, because this will warm up your wine.
