One of the country’s greatest treasures is The Portland Vase. This antique Roman amphora in translucent dark cobalt blue and opaque white cameo glass was bought in 1784 by the Duchess of Portland. The British Museum purchased the vase in 1945 after a long loan from the family’s collection. This treasure is a rich golden ale brewed using Calypso hops which give both zesty high-notes and a black-peppery finish.
