for whisky/whiskey and other high proof alcohols, make sure they are stored top up. The high proof will eat through a cork (high end booze). For screw tops, make sure to tighten the cap. For wine, it needs to be stored on it's side in a cool, dark, solid(without vibration) place. Anything with a proof of 40 or higher (20% alcohol) can be stored for the duration of your lifetime.
