Some basics

Hi Gone, and welcome to the Wine Board. A dry wine is one in which all the sugar has been fermented into alcohol. When some of the sugar is left over, it is known as residual sugar or RS. Exactly when a wine becomes sweet is in the taste of the beholder. Conventional wisdom pegs it around 3% RS. Some grapes such as riesling produce fine wines along the whole spectrum from dry to sweet with interesting stops along the way.
