Napa should embrace its heritage grapes

Napa Valley should embrace its heritage grapes such as Charbono and reduce its reliance on Cabernet Sauvignon, according to Jackson family winemaker Chris Carpenter.

Carpenter, a Cabernet specialist and winemaker for Jackson’s flagship Napa wine brands – Lokoya, Cardinale, La Jota and Mt Brave – expressed his concern about the Californian region’s almost total dependence on one grape, and said that he wished Napa would look to its past varieties.

“The Napa Valley is almost fully planted, and mostly with Cabernet Sauvignon, which is a pretty dangerous situation in terms of the monoculture we’ve created: if a pest ever gets in there, it could wipe out viticulture pretty quickly,” he said, during an interview in London with the drinks business earlier this month.

Explaining Cabernet’s dominance in the region, he added, “There is so much pressure in Napa to use varieties that pay for the cost of the land that even Sauvignon Blanc and Chardonnay are under pressure, even though they are good for cash flow.”

Considering that Napa has a dry Mediterranean climate, db asked Carpenter whether the region should look to Mediterranean grapes such as Syrah.

While acknowledging the quality potential from this variety, he said that it was the superior market demand for Cabernet that prevented more Mediterranean grapes being planted.

“We have two small blocks of Syrah on Mount Veeder, and I’m making a Syrah for our wine club… it’s not that you can’t make really good Syrah in Napa, for example, the Syrah from Coombsville AVA is very good, it’s just that the financial reality versus Cabernet is what doesn’t allow it to happen.”

Continuing he said, “The American public doesn’t get Syrah, so, a grower might get $1,000 per ton for Syrah” – which is in stark contrast to the income for Cabernet Sauvignon, which is $8,000 per ton, according to Carpenter.

In terms of white grapes, Carpenter said he would like to see more Mediterranean varieties in Napa, particularly Roussanne and Marsanne, although Chardonnay and Sauvignon Blanc are the dominant whites, again, due to the superior market opportunity for these grapes.

Finally, Carpenter said, “I’d like to see more heritage varieties come back, like Charbono, Petit Syrah or Zinfandel.”

Continuing he said, “Petit Syrah is one of the great varieties of the world; it has the structure of Cabernet but the depth of Syrah.”

As for Charbono, he said that only 18 acres (7.3 hectares) were left of the grape in Napa, and yet, “it is one of the grapes that established Napa”.

According to the Napa Vintners, Cabernet Sauvignon accounts for 40% of the region’s harvest tonnage and nearly 60% of the value of Napa’s annual crop.

The region’s leading five grapes by acreage are, in order, Cabernet Sauvignon, Chardonnay, Merlot, Sauvignon Blanc and Pinot Noir.

Although Charbono was once believed to be an Italian grape, UC Davis DNA analysis has shown that it’s the same grape as France’s Corbeau grape, or Douce Noire, which originates from Savoie.

It is also the same grape as Bonarda in Mendoza, Argentina, which has the largest plantings of the grape today, with almost 19,000ha in the ground, compared to 36ha in California and just 2ha in France, according to Wine Grapes.

As previously reported by db, Carpenter also expressed his wish that Merlot receive greater recognition for the quality of wine it produces, particularly in the Napa Valley.

“Merlot has been abused in the US… but Merlot produces some of the greatest wines in the world, from Petrus to Masseto,” he said.

Continuing, he observed, “Merlot does well when it’s grown in the right place and produced in the right way, and, beyond Bolgheri or Pomerol, there are spots in other parts of the world where it does well too, and one of those is California.”

Within the region he selected “sweet spots” for the grape in the Napa Valley, which he said were Howell Mountain, Spring Mountain, Mount Veeder and Stag’s Leap, although he also expressed his high regard for Verité’s La Muse, which is made from Merlot grown in Sonoma.
