San Marco, a new vinifera wine grape cross variety has been generating plenty of buzz in the eastern United States since the Quarella family, owners of Bellview Winery imported vines from Italy and planted them in their Landisville, New Jersey vineyard more than ten years ago.
My friend and winemaker Jerry Pompa (Instagram: @jerrypompa) piqued my interest in this promising grape after he attended a Quarella family presentation at the Eastern Winery Expo 2023.
San Marco was created in 1993 by Marco Stefanini at Trentino’s Foundation Edmund Mach. Trentino-Alto Adige is Italy’s northernmost region. It has weather conditions similar to those found on the East Coast of the United States with its temperature extremes, both hot and cold.
San Marco is a cross between two grapes of the Alto Adige, Teroldego and Lagrien. You can find my review of Castel Sallegg Lagrein 2019 and my interview with Castel Sallegg Director, Ulrike Platter by scrolling down this blog page.
San Marco has loose, medium-sized oval berries with deep pigmentation of skin and flesh, like another teinturier favorite of mine, Saperavi. Cane pruning is required and training on a VSP (vertical shoot position) trellis provides the best results in the U.S., as opposed to the pergola method used in Italy. One thing holding this variety back in the U.S. is the discovery of Grapevine Pinot Gris Virus (GPGV) and Grapevine red blotch-associated Virus (GPBaV) on some vines. Growers in Italy have experienced this same issue but say it has yet to affect the quality of their fruit or spread to neighboring vines. Virus-free vines should be available from Double A Vineyards doubleavineyards.com for $13.50 but are currently sold out. Jerry’s tasting notes for Bellview San Marco Outer Coastal Plain 2020 mention a dense plum color, black fruit, spice, cherries, and chocolate.
It is exciting to see a new red wine grape emerge with the potential that San Marco has. The wine culture in America continues to evolve and improve, albeit slowly but the future of this grape and others look bright.
