The Producer
The Bisol family has been making wine in Valdobbiadene since 1542. That figure is not marketing shorthand; it is the oldest documented date for continuous wine production by the family in the hills above Treviso, and the brand carries it plainly as Bisol1542. The current winery is run by two brothers: Gianluca Bisol as president and Desiderio as winemaker. In 2014 they sold a 50% stake to Grupo Lunelli, the Trentino group that also owns Ferrari sparkling wines, while keeping full operational and creative control.
The holdings are large by the standards of steep Prosecco country: nearly 190 acres of vineyard farmed across the Valdobbiadene zone, from younger two-year plantings to vines that are eighty years old. Production runs to 250,000 cases a year. Those numbers matter because the terrain they sit on is not easy ground. The hillside parcels require close to 900 hours of hand labor per hectare per year, a figure that sets the floor for how much the wine costs to make before a single bottle is filled.
Place
Valdobbiadene is a zone in the Veneto foothills northeast of Venice, where the Dolomite foothills meet the flat Piave plain. The town of Valdobbiadene gives its name to the DOCG, and the sub-zone of Valdobbiadene Prosecco Superiore covers the steep hillside parcels that form the historical heart of Prosecco production. Within that zone, Santo Stefano di Valdobbiadene is one of the named communes that regularly appears on bottles as a mark of more specific origin.
The terrain is the dominant fact about this place. Slopes steep enough to preclude mechanization, east and south-facing exposures that accumulate warmth through the growing season, and altitude variations that preserve cool nights and slow ripening. Glera grown here keeps higher acidity than Prosecco from the flatter DOC zones, and the wine reflects that: lighter in body, more floral, with a fresh finish rather than weight.
Soil And Site
The soils of Valdobbiadene are varied but a consistent type across the zone's steeper parcels is the clay-rich material locally called "crede." These soils drain well despite their clay content, hold moisture through dry periods, and produce wines with a particular mineral firmness in the finish. Bisol named their flagship DOCG wine after this soil type. Crede soils concentrate in certain parcels rather than covering the whole estate, and the blend composition of that wine, 85% Glera and 15% Chardonnay, is partly a response to the character those soils produce.
At the top of the zone's hierarchy sits Cartizze, a 107-hectare hillside within the Valdobbiadene DOCG that carries its own designation as Valdobbiadene Superiore di Cartizze DOCG. Bisol farms parcels here. The south-facing slope, concentration of older vines, and specific microclimate produce grapes that are richer and rounder than the estate's other vineyard sources.
Vine ages across the holdings run from two years to eighty. The oldest vines sit on the steeper parcels where replanting is most disruptive and costly, which means the estate's most labor-intensive ground also carries its most mature fruit.
Story
The Bisol family's wine history predates most of Europe's established estates. The documented trail runs to 1542, and the family remained in Valdobbiadene through the centuries when Prosecco was a regional table wine rather than an international category. The modern chapter begins around 1991, when the estate owned 17 acres and was producing approximately 8,300 cases a year. Gianluca and Desiderio later bought out their uncle and cousins to consolidate family control, and over the following two decades the vineyard base grew to nearly 190 acres and production reached 250,000 cases.
That scale was built on hillside ground. The brothers chose not to move production to the valley floor to reduce costs, which would have meant mechanization, younger vine stock, and flatter terroir. The steep parcels stayed in production, the 900-hour per-hectare labor commitment stayed, and the oldest eighty-year vines remained part of the farming program. The 2014 Lunelli partnership gave the family access to capital infrastructure without changing either the range or the viticultural philosophy.
Vineyards And Cellar
All Bisol vineyards are farmed by hand. On the steepest parcels, where gradient makes tractor work impossible, every harvest pass and canopy operation is done manually, which is why the labor count runs to 900 hours per hectare annually. The vine age spread from two to eighty years means the estate is continuously replanting while maintaining the old-vine parcels that produce smaller berries and more concentrated juice.
In the cellar, the Martinotti method, also called the Charmat or tank method, is used for Jeio Brut. The wine undergoes its secondary fermentation in sealed stainless steel tanks for a minimum of 30 days. This preserves the Glera grape's primary fruit character and natural aromatic lift more directly than bottle fermentation would, which is appropriate for a wine meant to be fresh rather than aged. Crede undergoes lees aging before its second fermentation, adding texture and a light savory depth to the mineral base.
Wines
The range moves in three clear steps. Jeio Brut is 100% Glera fermented under the Prosecco DOC, the appellation that covers a wider geographic area outside the DOCG hills. The Martinotti method and stainless steel tank fermentation keep the wine clean and immediate: fine, lively carbonation, citrus fruit on the nose, saline minerality, and a refreshing palate. It is the most widely distributed bottle in the range and the entry point into the estate.
Crede Brut is the estate's signature wine and carries the Valdobbiadene Prosecco Superiore DOCG designation. The blend is 85% Glera and 15% Chardonnay, the Chardonnay adding stone-fruit weight and floral complexity alongside Glera's natural acidity. Crede was among the first brut Prosecco Superiore wines released in the zone, at a time when the market expectation was for extra-dry sweetness. The wine is dry, mineral-driven, with white flower aromatics, a mid-palate of stone fruit, and a firm acid line into the finish.
Cartizze comes from the single hillside carrying the Valdobbiadene Superiore di Cartizze DOCG. The wine is typically made in a slightly sweeter style than Crede, reflecting the richer fruit the south-facing slope and older vine stock produce. It sits at the top of the range in concentration, texture, and origin specificity.
In The Glass
Across the range, Glera sets the baseline character: low tannin, moderate to high acidity, white flower and citrus aromatics, with alcohol typically below 12%. What changes across the three labels is weight and origin.
Jeio Brut opens with an intense citrus nose, lemon pith and green apple, with a saline edge that reads as mineral rather than salty. The carbonation is very fine and persistent. On the palate the wine is light-bodied and direct, refreshing and short in finish, built for aperitivo rather than the table.
Crede is a more layered wine. White flower comes first from the glass, then stone fruit, apricot and white peach, then a flinty mineral note that develops as the wine opens. The Chardonnay adds a cream texture to the mid-palate, but the acid line from the Glera keeps the wine from feeling heavy. The finish is firm and dry, with a chalky mineral persistence.
Cartizze brings more body than either of the preceding wines. The south-slope fruit is riper and rounder, the sweetness is perceptible without being soft, and the texture is fuller across the whole palate.
A Bottle To Understand It
Crede Brut Valdobbiadene Prosecco Superiore DOCG is the bottle that shows what Bisol's hillside farming and blend philosophy produce together. The wine is 85% Glera from crede-soil parcels in the DOCG zone, with 15% Chardonnay added for stone-fruit weight. Lees aging before the second fermentation gives it a texture and depth that the tank-fresh Jeio does not attempt. The nose is white flower and stone fruit, the palate mineral and dry with a firm acidity that keeps the wine fresh through the glass. No sweetness, no oak. Start here to understand why brut Prosecco Superiore is a different proposition from the extra-dry style that still dominates much of the category.
Anecdote
In 2014, brothers Gianluca and Desiderio Bisol sold half of their family winery to Grupo Lunelli, the Trentino group that owns Ferrari sparkling wines. The sale landed at the height of Prosecco's international expansion, when outside capital was entering the Valdobbiadene zone from multiple directions, and the obvious expectation was what usually follows when a historic family producer sells equity: new shareholders, new priorities, a gradual drift in label and range. None of that followed. Gianluca stayed as president. Desiderio kept the winemaking. The Crede label looked the same the next vintage, and the farming program on the steep parcels continued at the same 900-hour-per-hectare labor commitment. The brothers had exchanged equity for the capital infrastructure of one of Italy's most organized sparkling wine operations without transferring control of a single vineyard decision.
Final Word
Bisol is a large producer by Valdobbiadene standards, with nearly 190 acres of hillside vineyard and 250,000 cases of annual production. The scale could easily suggest compromise, but the terrain it sits on enforces a cost and commitment that industrial Prosecco avoids. The oldest vines in the estate are eighty years old. The steepest parcels are still farmed by hand. Crede remains one of the category's defining brut wines. For anyone trying to understand what Valdobbiadene DOCG Prosecco can be at its most deliberate, this is where to start.
