how long can whiskey keep
Unlike wine, whisky does not mature in the bottle. So even if you keep a 12 year old bottle for 100 years, it will always remain a 12 year old whisky. As long as the bottle is kept out of direct sunlight, the Scotch Whisky will neither improve nor deteriorate, even if it is opened. Whisky that is stored at very low temperatures can become cloudy, but the cloudiness should disappear when the whisky is returned to room temperature.
