Those who like to travel in style should check out the Wine Steward Supremo from Pek wards off the effects of aging – for your wine, at least – by filling unfinished bottles with argon gas to reduce the wine’s contact with oxygen. Because argon is heavier than air, when you remove the bottle from the Wine Steward and cork it, the air stays out. Unlike some anti-oxidation systems, the Supremo also has controls to keep your bottle at just the right temperature. It’s available in silver or black. ($199)
