Quinta do Crasto grows its grapes with techniques that are strongly ecologically based, and they don’t use any products or substances that aren’t certified, this fully respecting the environment and roots of their vines. The Late Bottled Vintage Port is made from a single vintage that is bottled after approximately 4 to 6 years of maturation in large Portuguese oak vats. Several grape varieties are used to produce this magnificent wine, harvested from vines that are over 60 years old.
