Dear Dr. Vinny,
Once you open a vintage—or, for that matter, a non-vintage—Port, how long can you expect it to last?
—Koen L., Woodbury, Conn.
Oxidation begins the moment you pop a cork on any bottle of wine. Keeping the leftovers in the refrigerator, in the smallest possible container (to reduce the surface area that’s exposed to air), will help slow the process down, but all wines will begin to deteriorate after a day or two. It’s true that the higher alcohol and residual sugar of Port will help protect against degradation, so you can expect it to last closer to a week or so, and in some magical cases, even longer than that.
