Red wine and white wine have health benefits, though red wine is arguably better for you. It is filled with antibiotics and can help curb your cholesterol and lower your blood pressure.
Wine is made through the fermentation of grapes or other types of fruit; around 99.9 percent of the world's wine is made from grapes. The process involves harvesting the grapes, crushing them, fermenting them, allowing the wine to age and then bottling it.
White wine has 25 calories per 1 ounce serving on average. The number of calories varies depending on the amount of sugar. The more sugar a wine contains, the more calories it has.
The calories in white wine come from alcohol and sugar, with alcohol containing nearly twice the calories. Alcohol has 7 calories per gram, while sugar and simple carbohydrates contain only 4 calories per gram.
Red wine contains more sugar than white wine. Red wine has 1.5 grams of sugar in every glass while white wine contains just 1 gram of sugar per glass.
A dry white wine is one that has been fermented to the point where most of its sugar is turned to alcohol. White wine can be fermented with its skin if it's from a pale-skinned grape, such as Pinot Blanc, or without its skin if it's from a dark-skinned grape.
Sauvignon blanc, pinot gris and pinot blanc are examples of dry white wines. Each of these wines is bottled in both the United States and abroad.
Alcohol triggers many wine-induced headaches, particularly migraines, according to the American Headache Society. Another culprit may be chemicals like histamines, tyramine and sulfites that are present in both white and red wines.
While drinking alcohol in excess may hurt your health, drinking red wine in moderation has many health benefits. A glass of red wine can protect against certain types of cancer, slow memory loss, fight weight gain and prevent cavities, according to Everyday Health.
A 4-ounce glass of white wine has about 100 calories, according to About.com. In general, 1 ounce has 25 calories, but white wines that are sweet or designed for desserts may have higher caloric counts.
