Trentodoc is a sparkling wine produced by the Classic Method, or Metodo Classico, and made only with Trentino grapes. After harvesting by hand, its winemaking process begins, one that has been passed down from generations, guided by passion and led by technology. It takes time and daily work for months or years before a Trentodoc is ready. One of the key parts of making a Trentodoc classic method wine is the secondary fermentation of the base wine, which takes place in the bottle.
