It is my understanding that regulations in the U.S.do not require/allow wine producers
to represent the nutritional information on wine out of concern that such may
promote consumption.
When asked, we are always hesitant to answer as we have never incurred the cost
to have any of our products analysized.
Accordingly, there's no way for us to represent to customers the exact nutritional analysis of a specific
wine.
Since the question is sometimes asked, we have taken the liberty - using information from the U.S. Department of Agriculture and other
web sources - of putting together a set of nutritional analyses based on typical wines. We think they'll give you a general idea of what to expect from a glass of your favorite red, white and dessert wines. Please note that specific bottles may vary. Even slightly sweet wines, for example, like White Zinfandel or many Rieslings, will carry more calories from sugar and more carbohydrates than the fully dry red and white wines listed. Wines stronger than usual in alcohol content, like a Chardonnay or Zinfandel at 13.5 percent or more, will also contain a few more calories than the average examples shown.
These charts are presented in the familiar U.S. nutritional-analysis format. We hope you'll find them interesting and useful.
A few obvious observations are that wines that are sweeter, as well as those that have a higher alcohol content will have more calories that the average ones.
Since most wines are made from fruits including grapes, the nutritional value presented in the tables will vary based on the alcohol content and the residual
sugar in the wine, both of which are usually available from the winery. On our site you can refer to our wine page and click on a specific wine to obtain these values.
A simple approach to determine the calorie content of a 5 ounce glass of wine that contains 10 percent alcohol is: 5 ounces x 10 percent x 1.6 = calories. Therefore the calculation is 5 x 10 x 1.6 equals 80 calories in this particular glass of wine.
The number of additional calories in a glass of wine from residual sugar are calculated as follows:.
Residual sugar at 2g/L means 2g/L = 0.002 grams per mL.
Example: A 5 oz. glass = 30mL/oz. x 5 oz. = 150 mL.
0.002 x 150mL glass = 0.3 grams.
0.3 grams x 4 calories per gram = 1.2 calories per 5 ounce glass.
