Churchill’s LBV is a field blend of many varieties such as Touriga Nacional, Tinta Roriz, Tinto Cão, Tinta Barroca, Touriga Franca and Tinta Francisca. It’s fermented in granite lagares until reaching 98 g/L of residual sugar, at which point it’s fortified with neutral grape spirit to 19.5% alcohol. It spends four years aging in wood. Bottled unfiltered— while it will not throw as much sediment as a vintage port, decanting is recommended.
