The different types of Port can be divided into 2 types: bottle types and barrel types. Ruby Port matures in bottle, is mostly fruit dominated and often dark, deep red in color. Tawny Port matures in the barrel, is wood dominated and therefore has a more brownish color. White Port and recently also Rosé Port are exceptions here.
For the Tawny, after these 2 years the Port is put into smaller barrels to get more contact with oxygen and continues to mature in barrel for up to 7 years and is then bottled.
Late Bottled Vintage Port is a Ruby type that is bottled after 4 to 6 years of aging in large casks.
Rosé Port is made from blue grapes. The very short contact with the skin gives it its pink colour. Rosé Port is kept in steel vats.
