The Terre d'autunno vineyard mainly grows Merlot. Half of the vines grow on the hill terraces at Monticello and Lumino and half in recent settlements on the plain at Lumino. The winemaking process is carried out separately for each of the vineyards’ areas of cultivation. The gneiss soil is acidic and the climate is somewhat fresher compared to the Sopraceneri towards Locarno. This gives the grapes more time to ripen and allows them to develop their character in the temperature fluctuations of day and night. All slopes are vinified separately.
The Terre d'autunno winery is the only winery in Switzerland that handles every step of the winemaking process itself, from vine growing to barrel making to vinification. The barrels are built from local oak trees, which makes Terre d'autunno wines completely regional.
