There comes a point in every life when you are adult enough (or rich enough) to buy more wine than you can drink all at once. About the same time you discover the wine shop gives you a decent discount for buying by the dozen. At this point you'll need something to store your wine, something stylish and stackable. Stylish so that it's joy to gloat over your wine hoard. Stackable so that you can keep buying more wine (and still keep it in your tiny NYC apartment).
Wine Stack wine rack from Umbra. Buy it from Umbra ($25) or Amazon ($18.73).
