How To Store Open Bottles: What Not to Do

Storing open bottles is easiest when you follow a clear order of steps. Most of the work is measuring carefully. Let's look at what makes storing open bottles work, and what you can skip.
Before you start
The key point is that keep a minor note on the label with the opening date, especially for vermouth and liqueurs. Store alcohol where children cannot reach it, ideally in a cabinet that closes or locks. Check the bottle for cloudiness, odd smells or sediment before pouring, and when in doubt, taste a modest amount before mixing it into a drink for guests.
Step by step
Most distilled spirits, such as whiskey, gin, rum, vodka and tequila, are very stable once opened. The high alcohol content protects them from spoiling, and a bottle can stay good for years if it is stored correctly. Still, air, light and heat slowly change the flavor, so a few habits help preserve what you paid for.
What to check
Store bottles upright, not on their side. Spirits with high alcohol can slowly damage cork stoppers if they are in constant contact, causing them to crumble or taint the contents. Keep the cap or cork tight after each pour, and choose a cool, dark place such as a cabinet or a closet, away from the stove, a sunny window or a heating vent.
Serving
Oxygen is the main concern for bottles that are nearly empty. When a bottle is down to a quarter or less, the large air space can gradually dull the aroma over many months. If you are saving a special bottle, transfer the remaining spirit into a smaller, clean glass bottle with a tight seal, or use a little inert gas product designed for wine and spirits.
None of this needs to be exact to the drop; taste and adjust to your liking.
Cleaning up
Put simply, some products need different treatment. Vermouth, aperitif wines and sherries should be refrigerated after opening and finished within weeks. Cream liqueurs also belong in the refrigerator and should be used by the date on the label. Fruit liqueurs and bitters are stable in a cabinet but keep best when capped tightly and kept out of the sun.
Fresh citrus does more for a cocktail than an expensive bottle.
Practical tips
Some practical points to keep in mind:
- Measure with a jigger rather than free-pouring.
- Never drink and drive; plan a ride home.
- Store vermouth in the fridge once opened.
- Chill your glasses before serving.
The bottom line
The best drink is the one you will make again. Take it one drink at a time. Each one teaches you a little more about balance.
Frequently asked questions
Do I need expensive bottles?
No. For storing open bottles, a solid mid-range bottle and good technique beat a pricey bottle used carelessly.
Can I make it ahead for guests?
Many stirred drinks can be batched and chilled in advance; add citrus drinks closer to serving.
What tools do I really need?
A jigger, a shaker or mixing glass, a strainer and a bar spoon cover almost every recipe.
Is there a non-alcoholic version?
Often yes. Keep the same balance of sweet, sour and bitter, and use tea, juice or soda as the base.
