Wine Denomination from Veneto
Montello Colli Asolani DOC is a wine denomination located in the Veneto region of northeastern Italy, officially recognized in 1977. The zone covers hills stretching between the Montello ridge and the Asolo hills (Colli Asolani), an area with a long viticultural tradition dating back to Roman times. The denomination encompasses a diverse range of wine styles, from still reds and whites to sparkling Prosecco-based wines, reflecting the agricultural variety of the territory.
The production zone falls within the province of Treviso, in the Veneto region, covering a series of gentle hills and morainic elevations between the towns of Montello and Asolo. The terrain is largely of glacial and alluvial origin, shaped by ancient glacial activity that left behind a mosaic of soils ranging from gravelly morainic deposits on the Montello ridge to clay-rich soils on the Asolani hills. The area sits at altitudes generally between 100 and 350 meters above sea level, with slopes that favor good drainage and sun exposure.
The denomination permits several grape varieties depending on the wine style. Red wines are primarily based on Cabernet Franc, Cabernet Sauvignon, and Merlot, often blended together or vinified as varietal wines. White and sparkling wines in the denomination are predominantly produced from Glera, the principal grape of Prosecco, along with permitted additions of Verdiso, Bianchetta Trevigiana, Perera, and Chardonnay.
Vineyards must be trained using traditional systems suited to the hillside terrain, with planting densities and yield limits set by the production regulations. Red wines typically undergo maceration with the skins to extract color and tannins, followed by aging in barrels, though the extent of oak aging varies by producer and style. Sparkling wines in the denomination are generally produced using the Charmat method (secondary fermentation in pressurized tanks), which is standard for Prosecco-style wines in the Veneto.
The red wines of Montello Colli Asolani tend toward a medium-to-full body with dark fruit notes such as blackcurrant and plum, supported by herbaceous undertones typical of Cabernet varieties and the rounded texture contributed by Merlot. With some age, the tannins soften and secondary aromas of leather, tobacco, and dried herbs can emerge. The sparkling whites are pale straw in color, with a fine perlage, and offer fresh floral and orchard fruit aromas — peach, apple, and white flowers — with a clean, moderately dry finish.
The Montello ridge is a distinctive elongated morainic hill formed by glacial deposits from the last Ice Age, composed largely of gravel, sand, and mineral-rich soils that drain rapidly and warm efficiently in the growing season. The Colli Asolani, by contrast, have soils with a higher clay and limestone content, which retains more moisture and contributes to wines with slightly more structure. The area benefits from a temperate climate moderated by the nearby Dolomites and the Adriatic influence, with warm summers, cool nights, and sufficient rainfall to sustain viticulture without irrigation.
Under DOC regulations, minimum alcohol levels are set at around 11% for most wine styles, with red Cabernet and Merlot wines generally requiring slightly higher minimums. The disciplinare (production rulebook) establishes maximum grape yields per hectare to ensure concentration and quality, with limits typically in the range of 10–12 tonnes per hectare depending on the variety. The denomination includes both base and Superiore or Riserva categories for certain red wine types, with the latter requiring additional aging — at least 24 months for the Riserva, including a period in wood and bottle.
