It\u2019s summer, and it\u2019s hot. You\u2019re thirsty, and your mouth is dry.\r\nWhat you really need is a wine that promises more of the same\u2014one loaded up with astringent tannins and/or mouth-puckering acidity, both of which will make your mouth feel even drier, right?\r\nAbsolutely not.\r\nAside from water, think about other hot-weather thirst-quenchers, like the ubiquitous gin and tonic, lemonade and sweet tea in the American South, sangria on the Iberian Peninsula and Thai iced tea (made with sugar and condensed milk).\u00a0\r\nThe commonality shared by all these beverages? They\u2019re sweet.\r\nSo are the fruits for which summer is famous. From strawberries, cherries and apricots through to blueberries, peaches, raspberries and beyond, the season\u2019s bounty is built on sugar.\r\nOf course, what makes all of these wonders palatable is not just the sugar they contain, but the natural balance of acidity they also provide when picked at just the right moment and coddled until serving time.\u00a0\r\nWhen properly made, that same balance of sugar and acid is precisely what makes sweet wines so appealing when temperatures soar. Just seek out wines with crisp acidity, modest alcohol levels and minimal tannin.\r\nRieslings often fit the profile, whether kabinett or sp\u00e4tlese from Germany or off-dry or semisweet Rieslings from Washington or New York. Moscato d\u2019Asti from Italy adds a bit of fizz to liven things up even further and maxes out at only 5.5% abv. Demi-sec or moelleux Vouvray, from the Loire Valley, is another top candidate.\r\nBecause of their sweetness and acidity, all of these can be served quite cold and still make a favorable impression on the palate, a plus when they might be standing in ice buckets or hiding in coolers. As an added bonus, all are generally reasonably priced.\r\nSo don\u2019t go crazy and pull out a magnum of 2001 Ch\u00e2teau d\u2019Yquem to chug by the pool just yet. (Or, if you are, give me a chance to get there first.)\r\nBut do consider including some sweetness in your summertime drinks. Your palate will thank you for it.\u00a0\r\n\r\n\r\n\r\n\r\n3 European Summer Refreshers\r\nAugust Kesseler 2012 R Riesling Kabinett (Pfalz); $18\r\nRipe peaches and tangerines backed by crushed stone and just-right sweetness create an invigorating wine.\r\nMarenco 2013 Scrapona\u00a0(Moscato d\u2019Asti); $16\r\nHints of honey impart a delicate sweetness to this semi-sparkling wine that\u2019s redolent of peaches, citrus and spice.\r\nEric Bordelet NV Poir\u00e9 Granit; $30\r\nThis profound, off-dry sparkling pear cider from Normandy comes from biodynamically farmed, 300-year-old trees.\r\nManaging Editor Joe Czerwinski\u2019s first wine was cold and sweet\u2014Weber\u2019s Zeller Schwarze Katz straight from the fridge\u2014and it made\u00a0him a sweet-wine\u00a0lover for life.
