They're the perfect wine for sipping in the day, at a picnic or at a poolside barbecue. Rosé happens when the skins of red grapes touch wine for only a short time. Where some red wines ferment for weeks at a time on red grape skins, rosé wines are stained red for just a few hours. The primary flavors of rosé wine are red fruit, flowers, citrus, and melon, with a pleasant crunchy green flavor on the finish similar to celery or rhubarb. Of course, depending on the type of grape the rosé wine is made with will greatly vary the flavor.
