Non-serious, but fun - and perfect chilled on a night where the temperature is still in the 30s - is Lambrusco Rosso. I never thought I'd hear myself say that. But this partially fermented grape must, still spritzy and sweet, reminds me of a winery during vintage time. There's a haunting grape-skin green leafiness underneath the sweet raspberryish fruit. The acidity and greenness that would make this a mean, tart wine if it were fermented to dryness, help counter the sweetness nicely, resulting in a refreshing, fruity drink that's low (4%) in alcohol. Cheap, too, at £1.58 from Asda.
