Reserve Port Wine is produced from selected grapes of high quality, and can be either white or red. In general, they stay in the wood for seven years and are then bottled. These wines must be treated in the same way as the standard ones, that is, they do not age in the bottle (therefore, it must always be kept upright) and after opening it can be consumed within a period not exceeding six months. Reservations have the particularity that they can be drunk either as an aperitif or as dessert wine. If you choose to drink before meals, it is advisable to serve it fresh, even if it is a red reserve.
