The Cantina Sociale di Trento Trentino sparkling wine is excellent: Zell Trento Doc Metodo Classico.
The Chardonnay grapes, carefully selected and harvested by hand in small crates are grown exclusively in the Zell area, a small district of Trento at an altitude of 500 m ASL on the slopes of Mount Calisio.
Like all Trento Doc sparkling wine two fermentation processes are needed, the second of which is done in the bottle. It remains on the lees for at least 28 months before being disgorged.
