Winemaker Joey Tensley describes oxidative and reductive styles of winemaking. The role of oxygen via micro-oxygenation in wines is discussed as well as the use of sulphur in the vineyard. At the end, Joey talks about whether or not micro-oxygenation in the winery might affect the ageability of red wines. Flimed at www.flickingerwines.com.
