Ca'Marian is a Valdobbiadene Prosecco Superiore bottling linked to the Cantina Produttori di Valdobbiadene (Val d'Oca) co-operative, which draws Glera from the steep hills between Valdobbiadene and Conegliano in the Veneto's province of Treviso. These slopes carry morainic and sandstone-marl soils, and the vineyards are worked largely by hand because of their gradient. As a Non-Vintage Superiore the wine reflects a house approach rather than one season: Glera is picked at moderate ripeness to preserve the grape's floral aromatics and bright acidity, and parcels from several sites across the DOCG hills are blended to hold a consistent style from year to year.

Grapes are pressed gently and the free-run juice cold-settled before a temperature-controlled first fermentation in stainless steel to retain freshness. The sparkle is created by the Charmat (Martinotti) tank method, with a second fermentation in pressurised autoclave over several weeks so the wine keeps Glera's primary pear, apple and white-flower character. It spends a short time on fine lees in tank before filtration and bottling under pressure. Finished as Extra Dry, it carries a dosage in the roughly 12 to 17 g/L range typical of the style, giving a rounded, gently off-dry palate balanced by the crisp acidity of the Valdobbiadene hills.
