An OCULUS was first used by the Romans in buildings like the Pantheon – a window in a dome or wall to the outside. At Mission Hill, our oculus provides the only natural light into our underground barrel cellar, blasted out of volcanic rock that is otherwise hidden from the world. Our complex Oculus Bordeaux-style wine is the result of meticulous selection in the vineyard estate with grapes that have been specifically nurtured for this rare wine.
