How to Determine if Wine is Sweet or Dry. Wine is mysterious and unpredictable. Although these qualities have created an enormous worldwide fan club, it does make an initial tasting a bit of a challenge. Use these tips--and your senses--to determine if a wine is dry, sweet or somewhere in the middle.
Know the basics. Dry wine is au natural--just the natural fermenting of a grape. Sweet wine, on the other hand, is fortified with additives that stop the sugar in the grapes from turning completely to alcohol. Therefore, sweet wines taste more honeyed because they have a higher level of sugar, while dry wines are less candied because the grape has been allowed to fully ferment.
Consider the type of wine you are tasting. Sauternes, Chablis and Riesling are considered dry white wines, while Claret, Burgundy and Chianti are considered the driest of the reds. On the other hand, Port, sherry, Muscat and Tokay are considered to be the sweetest wines on the market. Well-known varieties such as cabernet sauvignon, merlot and chardonnay can be sweet or dry, depending on the type of grape growth, additive and region.
Smell the wine. By sticking your face into the wine glass, you can pick up the "nose" of the wine. This will help you determine if the wine is sweet or dry. If you pick up scents of sugar, fruit or honeysuckle, you are probably dealing with a sweet wine. However, if you detect herbs, spices, wood or yeast, you have a drier wine. Be careful--some wines can carry scents of trickery, such as chocolate and citrus, which offer no indication as to whether the wine will be dry or sweet.
Taste the wine. Your best indicator as to whether a wine is dry or sweet is your tongue. Sip wine, let it rest on your tongue, swirl it around in your mouth, then swallow and wait for an aftertaste. A dry wine usually has a stronger taste on the tongue, but a clean finish. The taste of a sweet wine, on the other hand, tends to linger in your mouth for a moment after you have swallowed the liquid.
Utilize the tasting notes. It is sometimes difficult to determine the flavors in a wine. A wine that is supposed to be very dry may taste quite sweet on your tongue. Notes can help you discern among the many flavors. For example, reading about "hints of lemon and honey," may help you better pinpoint specific flavors that you didn't know you were looking for.
