How we tested
Champagne savers promise to keep champagne and sparkling wine fresh for anywhere from three days to a few months (a week would be plenty to us). We tested six savers ($4.44 to $35.00) by pouring a glass and a half from each bottle of sparkling wine, sealing them with the savers, and storing them in the refrigerator. We tasted them daily against a freshly opened bottle, one we sealed with just plastic wrap and an elastic band, and a bottle we left entirely open. The open bottle was barely effervescent after a day, as were the contents of the bottle sealed with one product with an exceptionally poor seal. Three of the savers—as well as the plastic wrap—kept the wine reasonably drinkable for two days, though their contents were not as boisterously bubbly as the fresh bottles. By day three, the wine was tannic and flat. Only one model really impressed us. Its easy-to-use, airtight seal kept the contents just as bubbly and fresh-tasting as a new bottle for two days and perfectly acceptable for a third. In a separate test where we didn’t open the bottle daily, the wine stayed fresh for a week. If you love bubbly but don’t want to drink a whole bottle in one sitting, this bargain saver is the best option on the market.
