1. Pulltap's Corkscrew ($10)
This compact, inexpensive, and durable wine key remains "the gold standard of bottle openers," says Tyler Lauletta at Business Insider. Note the double hinge, and the slender worm with a Teflon coating. It can be trusted with bottles that cost $20 or $800. Just keep an extra on hand. Buy it at Amazon.
2. Private Preserve ($11)
For most wine drinkers, there's no better way to preserve opened wine than a spray of Private Preserve. The mixture of inert heavy gases blankets the wine to prevent oxidation. Each use costs just 8 cents, and a can will last most drinkers two years. Buy it at Amazon.
3. Coravin Model Eight ($300)
This "ingenious" device lets you taste a fine wine before you even open the bottle. A slim needle pierces the cork, and the wine that's poured is replaced with argon gas to preserve the remainder. "For rare and valuable old wines, it's worth the price," says Paul Gregutt at Wine Enthusiast. Buy it at Amazon.
4. Plum Wine Dispenser ($1,499)
At last, a countertop appliance that "pours the perfect glass at the touch of a button," says Katie Kelly Bell at Forbes. The Plum holds two bottles, each chilled to optimum temperature based on label data. Like the Coravin, it uses a needle to extract a serving and preserve the rest. Buy it at Plum.
5. Corkcicle Canteen ($33)
Corkcicle's triple-insulated, stainless-steel canteen will keep any beverage cold for 25 hours. The 25-oz size is just right for a 750 ml bottle of white or rosé — and "perfect for a glass-free zone, or when you're miles away from a refrigerator," says Wine Enthusiast. Buy it at Amazon.
