Question: why are you supposed to drink red wine warm?
Answer: Fuller-bodied, tannic wines like Bordeaux and Napa Cabernet Sauvignon taste better warmer, so keep them to 45 minutes in the fridge. Red wine that's too cold tastes dull, but when too warm, it's flabby and alcoholic. ... Lighter, fruitier wines work best colder, between 45°F and 50°F, or two hours in the fridge.
