The reform included some liberalisation of the regulations surrounding the EU table wine category. Like today, these varied in quality from common table wine to valuable vintages. Ice wine usually has a slightly lower alcohol content than regular table wine. It is also starting to gain popularity as a table wine component in China. Some marketing terms, such as "light" and "table wine", must follow TTB guidelines. Most EU countries have a national classification called "table wine" in the country's official language. Wines which do not meet this requirement may only be marketed as table wine. The fraction of national production classified as table wine varies dramatically from country to country. Table wine includes the designations "Deutscher Wein" (previously Tafelwein) and "Landwein".
