This Port is aged for 4 to 6 years in large old oak vats (as opposed to Vintage Ports, which age for 2-3 years). LBV Ports fill the gap between Ruby and Vintage Ports, as Rubies should be drunk quite young and a Vintage Port may need 15 to 20 years to open up and show its splendor. This led to the creation of a Port in the 1960s which would undergo 4 to 6 years of aging in large vats before being bottled, resulting in a wine of a Vintage Port style with its deep color and concentration of fruit but with a more mature character due to the extended aging period in wood.
