Here is a list of most (not all) of the different types of port:
-White Port
-Ruby Port
-Young Tawny Port
-Aged Tawny Port
-Vintage Character Port
-Late Bottled Vintage Port
-Traditional Late Bottled Vintage Port
-Vintage Port
Most styles fall into two broad categories: Bottle aged or Cask aged. Because doing the tiniest thing different will result in a different taste of wine, the two Port processes greatly dictate the flavorful outcome. While Bottle aged Ports generally behave like wine on Botox, keeping their color and their fruitiness well into maturity, Cask aged Ports lose flavor quickly. They are ready to drink right away.
