Refers to the small air space in a wine bottle or barrel. Excessive air in the bottle increases the speed of oxidation.

Umami
Although there is no direct English translation, umami is essentially the fifth taste. Discovered and noted by Chinese gourmets more than 1,200 years ago, the concept is fairly new to western scientists and gourmets alike. Mushrooms, consommés, long-cooked meats, cured meats, shrimp, dried tomatoes and soy sauce all contain umami. This taste tends to bring out tannins or the oaky character in wines.
