There are many styles of port wine, but four are the most important.
- The white, which can be dry or semisweet.
- Among the reds, the most common is the ruby, a young wine that owes its name to its color.
- There is also the tawny, aged in wood for many years (not less than six) where by oxidation becomes a dark amber color.
- Finally, the vintage, the wine that has given its reputation to Porto, which comes from an exceptional crop, which is bottled young, unfiltered, to maintain all its structure and fruity characteristics.
