Bright colors are in this summer, and Vacu Vin has just what you need to dress up your unfinished bottles of wine. Their reusable vacuum seal corks come in a cheerful color palette ($8.50 to $10 for a 3-pack). The company suggests using them to “label” your wine: turquoise for whites, pink for roses, and purple for reds. Pop in the stopper, remove the excess air with the Wine Saver vacuum pump ($9.99 to $12.95 with one gray stopper) to reduce oxidation, and you’ll have a few more days to enjoy that bottle. Savor a glass or two of wine with your dinner on the patio, and save the rest for another night.
