Port is a fortified wine that originates from the Douro Valley in Portugal. It is typically a sweet, red wine, although there are also white and rosé varieties available. Port wine is produced by adding a neutral grape spirit, known as aguardente, to partially fermented grape juice, which stops the fermentation process and leaves behind residual sugars, resulting in a sweet and rich wine. Port is known for its deep, complex flavors, often featuring notes of dried fruits, nuts, spices, and chocolate. It is commonly enjoyed as a dessert wine or paired with cheeses, nuts, and chocolate-based desserts.
