Our take
What we make of this bottle
$13.99 is the lowest price our September 2026 checks caught on this bottle. It is a confirmed Prosecco DOC, made from Glera, the white grape the Prosecco consortium holds up as the category's traditional variety. Shoppers put it at 4.79 out of five, across 42 scores read on August 12, 2026.
The odd thing about this wine is geography. By the winery's own history, the Coppola family has owned its Geyserville, California estate, once known as Chateau Souverain, since buying it in 2006, yet this wine is not from there. It is made in Italy under the Prosecco DOC rules, in a category the consortium describes as floral, fruity and fresh, and the consortium says the labeled sweetness term, on a scale from Brut Nature down to Demi-sec, tells you how dry the wine is. The top of the range in those September 2026 checks was $22.99, across ten stores, each checked on its own date.
The producer's page for this exact wine adds the method behind the bubbles: after whole-cluster pressing and a first fermentation in stainless steel, the wine gets its bubbles from a second fermentation in sealed tanks, the Charmat method, using selected yeasts, a process the producer credits for preserving the wine's delicate aromatics. Alcohol content is 11 percent, lower than most still wines, and the producer's own tasting profile names red apple, citrus and white peach with "vibrant acidity" and a "creamy finish," the producer's words. The page also cites two competition results for this wine: 97 points and a Platinum medal from the Las Vegas Global Wine Awards, and 95 points and a Best of Class win from the Los Angeles International Wine Competition.
Our call: a sound reach for the shopper who wants Prosecco made under the DOC's own rules with the crowd already weighing in; one of the larger rating pools we track has placed it above the middle of the rated wines we cover, and the producer's own page adds competition recognition, a 97-point Platinum from the Las Vegas Global Wine Awards and a 95-point Best of Class from the Los Angeles International Wine Competition. Pass if the Coppola name is pulling you toward the family's Geyserville estate, because this bottle is a confirmed Prosecco DOC made in Italy, not a wine from the California estate the winery describes.

Research status
What we are still checking
Our overview above draws on the dated store feed, shopper ratings, our region and grape research, and any sourced producer facts. We are still working to confirm the current release, the full producer record, and the bottle itself, and we update this page as we learn more.
Getting to know Prosecco DOC.
Judge it as Prosecco: a Glera-led, tank-fermented sparkling wine built around freshness and fruit, not as an inexpensive imitation of bottle-fermented Champagne.
What the name means
A controlled denomination since 2009 covering specified provinces in Veneto and Friuli-Venezia Giulia.
How grapes grow here
The DOC crosses plains and hills in northeastern Italy; the broad designation does not identify one village or exposure.
What lies under the vines
Alluvial, clay-loam and hill soils occur across the zone; the base DOC alone is not a single-soil claim.
How large the region is
- Method
- The Martinotti–Charmat method carries out secondary fermentation in pressurized tanks to preserve fruit and floral character.
Places within the region
- Grape rule
- Glera is the base; permitted grapes may contribute up to 15%.
Getting to know Glera.
Glera is the white grape behind Prosecco. The Prosecco consortium lists Glera as the traditional variety, and a short list of other permitted grapes may be used up to 15 percent in total.
Category guide
What to expect in the glass
The consortium describes floral and fruity character, a fresh taste and a straw yellow color across the category. Most bottles are sparkling or semi-sparkling, and the labeled sweetness level, from Brut Nature through Demi-sec, tells you how dry the wine is.
