Red wine is made predominantly from dark grapes and takes its colour by leaching it from the skins during the wine making process.  The longer the skins are kept in contact with the juice, the deeper the resulting colour.  The contact with the grape skins and sometimes the stalks and seeds are what gives the wine tannin.  During the fermentation process, the temperature also has a large part to play.  The higher the temperature, the more colour and tannin is imparted into the wine.  We aim to offer you great examples of as many grape varieties as possible.
