How long does open/unopened liquor stay good??

Have bottles of liquor and liquour, some open and other not opened. Also have unopened wine.|||Liquor will last you for how ever you would want it to last you. Beer opened will last you about a few days not opened about a couple years.|||LIQUOUR WILL BE GOOD INDEFINATELY OPENED OR NOT.....LIQUOR IS THE SAME ..UNOPENED BEER HAS A SHELF LIFE OF ABOUT 3-5 YEARS IF STORED PROPERLY IN A COOL ENVIRONMENT. UNOPENED WINE STORED PROPERLY HAS A SHELF LIFE OF 1-3 YEARS. FRUIT WINES MUST BE DRUNK WITH IN ONE YEAR.
