How we tested
An ice bucket keeps wine cool for the duration of a meal and can even chill a room-temperature bottle. But we found three innovative wine chillers priced from $25 to $50. Could they beat the bucket? The Corkcicle, a cork-capped prefrozen plastic tube inserted in the bottle, kept Chablis that we prechilled in the refrigerator below 50 degrees for only 20 minutes. The Ravi Instant Wine Refresher, a freezer-gel cartridge that fits on the mouth of the bottle, made pouring slow and awkward and lost its cooling ability after only 25 minutes. That left us with our winner, a glass carafe with a stainless steel insert that holds ice, which kept the wine below 50 degrees for 90 minutes. It was also the only device able to chill a room-temperature bottle, dropping it to 50 degrees in 15 minutes.
