#4. Hard liquor
Whipping up some penne alla vodka and a pitcher of cocktails? Distilled spirits —vodka, rum, whiskey, gin, tequila and the like — don’t spoil, even after opening. The taste and aroma may fade gradually, but it’ll take ages before you notice. Keep it fresh: Store in cool, dark area, away from direct heat or sunlight. Keep bottle tightly closed when not in use.
