Can vodka evaporate in a sealed bottle?
Keep the bottle sealed for as long as you can. An unopened bottle of vodka can be stored indefinitely. Because of this, you should wait to open a bottle until you're actually ready to start drinking it. The alcohol in the vodka starts to slowly evaporate once the seal is broken and the bottle is opened.
Both the water and the alcohol in wine are subject to evaporation, and typically the alcohol will evaporate somewhat faster than the water does. But it really depends on a lot of different variables, including the temperature, the airflow and how much of the liquid's surface area is exposed to air.
- If the cork is sealed well, the whisky should not evaporate. However, natural cork is organic, and can be damaged or even be deteriorated by prolonged contact with the whisky if the bottle is stored laying down, it can also dry out (although in full sealed bottles this is rather rare).
- Overindulging will almost always lead to unpleasant symptoms. But it sounds like you're wondering if a wine spoils as it gets older, and the answer is no. The alcohol acts as a preservative. Even on the rare chance that a wine has turned to vinegar, it would be unpleasant to drink, but not dangerous.
- After being added to food that then is baked or simmered for 15 minutes, 40 percent of the alcohol will be retained. After cooking for an hour, only about 25 percent will remain, but even after 2.5 hours of cooking, five percent of the alcohol will still be there.

- So that means for every hour you are not drinking, .015 of the alcohol in your body is being metabolized and disappearing from your body (thanks to David J. Hanson, Ph.D. for this information). So, if your BAC was 0.08 (legally impaired), it would take about 5.33 hours for the alcohol to be eliminated from your body.
- Second, most experts agree that if you have less than half the bottle left, you should finish it within 1-2 years. If you have a quarter left, finish it within 3-4 months. The oxygen in the air oxidizes the whisky, which can impact the flavor. Alternatively, you can always use wine preservers like Private Preserve.
- In general, distilled spirits are quite hardy. Unopened bottles of whiskey can last for generations. An unopened ten or 12 year old Scotch or rye should be good as new (assuming it has been handled properly, not subject to extreme temperatures, etc.).
