This weekâ€™s Wine Word of the Week is ullage.
Official definition from Jancis Robinsonâ€™s The Oxford Companion to Wine:
Ullage, which derives from the French ouillage, has had a variety of meanings and uses in the English-speaking wine trade. It can mean the process of evaporation of wine held in wooden containers such as a barrel. The head space left in the container is also called the ullage, or â€˜ullage spaceâ€™, and the wine in that state is said to be â€˜on ullageâ€™. The word ullage is also used for any space in a stoppered wine bottle not occupied by wine. And ullage is also used as a verb so that a bottle or barrel not entirely full is said to be â€˜ullagedâ€™.
Laymanâ€™s terms from Kori:
Ullage is most commonly known as the space between the wine and the cork in a bottle of wine. Too much ullage increases the danger of oxidation.
