Store in a cool, dark place at 50-55 degrees, (do not fluctuate temperature, keep constant). Wine turns/oxidizes at 75 degrees. Store horizontally to keep the cork moist and prevent it from drying out. Keep still. Try not to move the wine bottles once stored. Dark green bottles are preferable.
Store upright to minimize oxidation between beer and bottle cap, and so unfiltered beer sediment stays on bottom. Like wine, it is recommended to find a cool, dark place with a temperature of 50-55 degrees. Most beers have an expiration date and are not recommended for aging, except for those heftier beers that are ripe for maturation, such as: vintage beers, barleywines, imperial stouts, Belgian strong ales, lambics, and old ales…
Store upright. The theory is that lids are less reliable and can leak. A bottle of vodka will not go bad due to its alcohol content.
Not if bottles are stored in a cool, dark place (*more on storage later). Direct sunlight and fluorescent or UV lighting will speed the oxidation process. The darker the tint of glass, the more light diffused, helping to protect the liquid within.
Clear bottles are popular with white wine producers, however, most red wine worldwide is still bottled in green glass. Beer is typically stored in green or brown bottles, as well as clear. Liquor comes in a myriad of colors, mostly due to Marketing.
