Why it matters
The producer
Sarah Dei Tos founded La Vigna di Sarah in 2010 on a hillside in Vittorio Veneto that already had a name to live up to. Col di Luna, the hill of the moon, takes its name from the moonlight that floods the slope on full moon nights. Dei Tos planted 16 hectares of Glera on that slope and eventually built her most distinctive wine around the hill's defining quality: she harvests Grappoli di Luna at night, making it the first and only Prosecco DOCG picked in darkness.
The estate sits in the Province of Treviso in the Veneto, roughly 15 minutes from Valdobbiadene, the historic centre of Prosecco DOCG production. In 2014 Dei Tos opened Lunotte, a farmhouse agritourism operation on the same hill, and the vineyard is currently working toward organic certification across all 16 hectares.
Place and vineyards
Where the wines begin
Vittorio Veneto is in the foothills of the Dolomites in northeastern Italy, on the northern edge of the Prosecco DOCG production zone. Valdobbiadene, 15 minutes to the south, gives the zone its historical name and its Superiore sub-designation. Col di Luna sits within the broader Prosecco DOCG area, and the wines carry that classification without a confirmed sub-tier.
Prosecco DOCG is built entirely around Glera, a white grape with natural white berry character and moderate acidity. The zone's sparkling wines are made to be aromatic and approachable, with freshness rather than weight as the guiding note. The hillside position of Col di Luna adds exposure and airflow, and the vineyard's name points to the conditions that Dei Tos decided to farm against deliberately: cool nights and clear air.
In the cellar
Vineyards and cellar
All 16 hectares are planted with Glera. The vineyard is in transition to organic methods across the entire estate, though the certification body and expected completion date are not yet confirmed. Night harvesting is the defining practice: for Grappoli di Luna, the Glera grapes are picked after dark, when temperatures on the Col di Luna slope are at their lowest and the fruit retains its aromatic load. The cooler picking window slows the enzymatic activity that would otherwise start breaking down the grape's volatile compounds before they reach the press.
Wines to know
The range in view
The estate produces two documented bottlings, both from Glera.
Glera Brut is the estate's standard expression at 11.0% alcohol, classified as Prosecco DOCG. It carries the characteristic white berry profile of the variety, with the lightness and freshness typical of the category.
A useful way in
A bottle to begin with
Grappoli di Luna Extra Brut is the bottle to start with. It is a night-harvested Prosecco DOCG from Glera grown on Col di Luna, at 11.5% alcohol and classified Extra Brut, placing it at the drier end of the Prosecco range. The wine opens with wisteria, acacia, and citrus, and the lower sugar lets those aromatics read cleanly against a dry, lightly fizzing finish. The night-harvest origin is not a marketing story applied over a generic wine: the aromatics in the glass are the direct consequence of picking in cool darkness rather than afternoon heat. Start here to understand what the hill, the grape, and the decision together produce.
