Vinesugar : Wine Glossary and Terminology

Wine Glossary Terms: U

ullage: This French term - pronounced "ull-idge" in English - refers to the air space in the neck of an unopened bottle of wine. This air bubble will be entirely within the neck of a normal bottle, but older bottles that have lost some of their contents may be described as having a "mid-shoulder fill" or even "low shoulder fill."
umami: About a century ago, Japanese scientist dubbed the term "umami" - it is the fifth tasting sense beyond sweet, sour, bitter, & salty. It is the "savory" sensation found in foods like: oysters, tomatoes, and mushrooms. This sense puts its emphasis on tannins - wines to appeal to this sense would be mature reds (soft tannins) and certain white wines (those without oak influence).
