Whether or not you feel Carl Doumani possesses the traits of the fictional hero for which his winery is named depends on how well you know him.

As designed by the witty Viennese artist, architect, philosopher and environmentalist Friedensreich Hundertwasser, Doumani’s Quixote Winery does indeed capture the spirit of Miguel de Cervantes’ celebrated character.

But the wines crafted by Doumani and winemaker Mario Monticelli are anything but quixotic, as they’re sound, sure-footed, practical expressions of the Stags Leap winegrowing district, a region of the Napa Valley renowned for its silky cabernets.

If Doumani did tilt at windmills, he did it a long time ago. After all, who but a brash visionary like Doumani would have planted petite sirah (he prefers the syrah spelling) in an area not yet proven for hearty, late-ripening reds. But with neighbors like Nathan Fay and Warren Winiarski doing so well with Bordeaux varietals, Doumani was inspired to focus on his favorite wine, petite sirah. As others in the valley pulled out old petite sirah vines, Doumani planted anew.

That was more than three decades ago, when Doumani was chief cook and bottlewasher at his Stags’ Leap Winery. When he sold that winemaking operation to Beringer more than a decade ago, he decided to scale back and work on a wine project focusing on small lots of — what else — petite sirah, as well as cabernet sauvignon.

Doumani was a fan of Hundertwasser’s works. But getting this reclusive artist to design his winery was easier said that done. He eventually made contact through a mutual acquaintance, only to learn that the Austrian architect was a fan of Stags Leap District wines. Still it took Doumani a decade to realize his dream.

Not only did he wind up with a Hundertwasser-designed winery (the only Hundertwasser project in the United States, by the way), Doumani convinced the Austrian to do his Quixote label.

Now, several years into the project, Doumani is producing two wines each for two labels, Quixote and, appropriately, Panza, from 27 acres of organically farmed estate vines. As he doesn’t use all of the fruit for his Quixote and Panza labels, some of the wines are bulked out.

Shortly, he will reach his planned production goal of 70 percent petite sirah and 30 percent cabernet sauvignon, with total production between 4,000 and 4,500 cases.

Doumani tends to bottle age his wines more than most. Current releases are 2001 for cabernet and 2003 for petite sirah.

Since 2001, all of Doumani’s wines are finished with screw caps. “I think it’s the best closure we have to date,” he says of his decision to forsake cork.

Panza 2001 Cabernet Sauvignon ($40): The Panza wines are the easy-to-drink-upon-release offerings from this small operation tucked in the shadow of the Stags Leap palisades. A lush, silky expression of this varietal with very little oak in nose or palate, it has wonderful red cherries and plums on the extended finish. An elegant wine at a very good price. But don’t tell Carl.

Quixote 2001 Cabernet Sauvignon ($60): A bit more structure and finesse for this cab from a great vintage for Stags Leap and other Napa Valley reds. Blackberries and plums are evident on the nose of this soft, supple cabernet, with blackberries and currants lingering on the slightly sweet finish.  A wine to drink today, but one that should be even better with a few more years in your cellar.

Panza 2003 Petite Syrah ($40): A well-balanced, ruby-colored elixir with an intoxicatingly spicy nose, this one’s a bit riper than its counterpart. Maybe that’s because of the fact that it’s blended with some syrah, mourvedre and grenache. A toasty nose and a mouthful of berries are its hallmark. Definitely a food wine, it’s ideal for spicy Italian dishes, your favorite barbecue or marinated game.

Quixote 2003 Petite Syrah ($60): A meaty, juicy, slightly smoky wine packed with black fruit, this is a single varietal wine that I found to be an ideal pairing for roasted wild duck breast. It has layers and layers of flavor, notably blackberries, and has an appealing long finish of blueberry and dark chocolate. Only 300 cases were produced, so a word to the wise — get some.

Locally, you can find Panza and Quixote wines at V Wine Cellar in Yountville’s Vintage 1870 and at Dean and DeLuca in St. Helena. The wines are on lists at Mustard’s Grill, Zuzu, Angele and Terra.
