The practice of opening a bottle of wine an hour before enjoying it to let it breathe amuses many wine experts. “How much air can get into the bottle?” asks Amy Reiley, author and wine expert. “Really you just give your arm a rest after before you drink it.” Letting a wine breathe in its own bottle won’t help improve the wine’s palatability. What the wine may need is more oxygen in order to age a big, young red. “To have contact with O2, more surface area has to be in contact with the wine. A decanter has the widest possible surface area. It is less vertical and spreads out horizontally. The O2 permeates the outer skin of the wine as thin as an inch, aiding it along, opening up the wine,” says Tyler Wesslund, wine director of Canoe in Atlanta.
