"Better for you" wines are the hot trend of 2021. The moniker for these health-marketed wines hasn't yet been universally agreed upon, and Nielsen doesn't yet track this as a category. But big wine companies and big grocery chains are buying into the idea, and there will be several significant launches in the months to come.
Broadly speaking, this new category of "better for you" wines shares two characteristics. First, they are lower in alcohol, through mechanical means of alcohol reduction. Second, they have zero residual sugar. Thus a naturally low-alcohol German Riesling made from organic grapes and natural yeast would not qualify if it has RS, while a wine that has been stripped to its component parts and reassembled at 10% alcohol would.
