How do you store tawny port?

Tawny port should be stored upright in a cool, dark place, ideally between 55-65°F (13-18°C). Once opened, it can be kept for several weeks to a few months, thanks to its oxidative aging process. It's best to seal the bottle tightly and refrigerate it to maintain its quality for as long as possible. Avoid exposure to light and temperature fluctuations to preserve its flavor.
