Personally, I have not read the South Beach Diet. Nevertheless, the assumption is that you get to drink a lot of wine due to all the dancing, walking, swimming, and biking around Miami's South Beach...thereby, lots of wine and activity will help you to lose weight! That works for me!
The good news is if you do count carbohydrates, wine is naturally low in carbs. Yes, that is even according to the government's "low-carb" criteria, where the wine must have lower than 7 grams in a 5oz serving. Most Champagnes and dry wines will easily make that classification.
In the situation where wines come with slightly higher carbohydrate content (more than 7 grams), the government approved the use of the terms "reduced carbohydrate" and "lower carbohydrate" (as well as similar terms). These can be used on labels or advertising as long as the term is used as part of a statement that specifies the number of carbohydrates per serving size, and compares that number with the number of carbohydrates in another specified product made by that producer.
The carbohydrates in wine are due mainly to the alcohol content, as there are only small amounts of fruits and other sugars. Analyzing a 5-oz. glass of typical dry wine (ex. Chardonnay, Merlot, Zinfandel, or Sauvignon Blanc), you may be pleasantly surprised has only around 1.5 grams per serving...Hurrah for wine!
In summary, the US government is allowing winemakers to show off and advertise its low-carb status. With the huge low-carb marketing successes, as example Michelob Ultra, expect to see more wine producers labeling and branding their wines in a similar manner.
