"You Really Love a Smooth Grenache"
Good news here if you think dandelion greens are more compelling when paired with a strong drink. A study published in the American Journal of Clinical Nutrition found that red wine's polyphenols—those compounds whose heart-healthy benefits you've heard so much about—also have prebiotic potential. Just one glass (9 ounces) of red wine daily for a month meaningfully boosted drinkers' ratios of good-to-bad gut bacteria (compared with alcohol-free and polyphenol-free gin-drinking controls). A caveat: The benefit doesn't apply to sweet dessert wines, which presumably feed the wrong microbiota.
