The caves at Del Dotto Vineyards & Winery

At an estimated cost of $10+ million, the lavish wine caves at Del Dotto Winery offer a glamorous front to the sometimes gritty winemaking process.

Gerard Zanzonico’s Winemaking Adventures in Xanadu

At Del Dotto Vineyards and Winery, Gerard Zanzonico juggles many balls (and barrels and yeasts, and vineyards).

September 6, 2007

Gerard Zanzonico has been around the block, through the neighborhood and onto your stoop. Both in his native Brooklyn, where we hear he was quite a stickball player, and in the Napa Valley where he has been the winemaker for some high profile properties.

But now that he's arrived at Dave Del Dotto’s extraordinary piece of Rutherford, Zanzonico's street cred is about to rise exponentially. When Del Dotto gets through with him, Zanzonico will be able to balance those New York spaldeens (Spauldings to the rest of you outliers) on the tip of his considerable proboscis.

That’s because Del Dotto is a crazyman when it comes to barrels. The former real estate developer is giddy from experimenting with oak barrels whose collective staves come from various forests.

Not only that, Del Dotto is playing around with giant clay amphora in which to ferment some of his wine.

Not only that, Del Dotto has got it into his head to fool around with a myriad of yeast strains.

Not only that, Del Dotto has chosen to put all those barrels and amphora into a wine cellar with 40-foot ceilings and columns (at the tune of a guesstimate on the far side of $10 million), that are made from imported Italian tile and which make the cellar resemble a Naples museum. (It was scheduled for completion by mid-summer. The caves on Atlas Peak Road in Napa will be retained. The winery currently produces 8,000 cases, but there are plans now to bump that to about 12,000.)

So Zanzonico ( pronounced zan ZON ee co) has his work cut out for him. Stints at Chateau Montelena, Stonegate, Staglin, and Benessere hold him in high stead. But wait until Dave Del Dotto is through with him.


ALAN GOLDFARB (AG): So, what have you gotten yourself into now?

Caught in the act: Gerard Zanzonico tanked up.
GERARD ZANZONICO (GZ): The exciting part of Del Dotto is the amazing diversity of fruit from the vineyards to work with. He’s a serious player in the valley. There’s a real dedication and he’s making a statement. It’s important that you extract the personality of the individual vineyards.

AG: We’ll get to those vineyards later but first, I want to know why does Dave Del Dotto seem so focused on barrels?

GZ: It’s one of Dave’s qualities. He feels it’s a spice rack, and it impacts different flavor profiles, which I think is true. You can have a great vineyard site, but you need to enhance it with a cooperage selection to see what works best on what vineyards. Underneath the marketing concept, there’s a production concept.

AG: Do you like working with that palette of barrels?

GZ: I enjoyed working with that at Staglin [from 2003-05]. I have learned so much more about different forests, thicknesses (of the wood). You don’t always get an opportunity to taste that many different kinds of barrels in one facility.

AG: How many different types of barrels?

GZ: We have them from Missouri, Pennsylvania, France, from nine French forests.

AG: Does all that make your job easier?

GZ: It gives me a broader profile palette to work on and to work with. It’s an interesting work environment to be involved in. It would probably be easy to work for a winery that had a formula. But this is a lot more interesting. Before we rack, we sit down and taste every barrel for tannins, structure, finish. It’s eye opening.

AG: And what’s up with the clay amphora?

GZ: > We ferment in them. It has interesting characteristics that you get from natural clay. There’s an earthiness that you don’t get from oak or stainless steel. It’s a whole new ballgame with clay or concrete. Last year we had four lots - two Zinfandels and two Sangioveses with natural yeast - in those amphora, which will affect flavors. It’s another component to what Del Dotto has to offer. It’s very exciting.

AG: And now come yeast-strain experiments.

GZ: Different cultured yeasts. We’ll take a vineyard that might be eight, nine tons (per acre) and subdivide into four, five different yeast programs and then take those and put them on different oaks. You can look at all the wines with the same characteristics and with different yeasts.

AG: Now, tell me about the various vineyards from which you source fruit.

GZ: First there’s the Harrison Vineyards property we just bought on Pritchard Hill (in the tony eastern hills above St. Helena). It’s planted to 40 acres of Cabernet Sauvignon with a 10 to15,000-case facility,

where we’ll make about 1,200 cases. Some of the upper portion has over 20-year-old vines; while the lower was planted three and four years ago, which has flavors that are just great with plum, currant, dense, fleshy, tar characteristics that grip the palate with nice, tamed tannin. It has tremendous potential.

A mountain vineyard like that is not going to come about too often. The Harrisons always made good wines. I’m walking around and looking at tiny clusters and all of a sudden I find another niche. The vines are going over the slope and into the canyon. It’s going to be challenging with all different exposures, drainage and soil types. Each (lot) will have to be kept separate.

It’s an exiting piece of property which you don’t see on the valley floor.

AG: The next vineyard?

GZ: There’s the estate (14 acres on West Zinfandel Lane north of Rutherford). It has gravelly soils that have washed down from the Maycamas Range. There’s Sangiovese and red Bordeaux varieties. The wines tend to be rich and extracted with that Rutherford dust quality, and deep purple color. It’s different from the valley floor.

AG: Everyone in Rutherford goes on and on about the dust, but few can actually define it. Can you?

GZ: That’s a difficult question. It’s a certain kind of earthiness in the nose that conveys to the flavors. It’s an earthy character, not berry character that you get from some Cabs.

AG: St. Helena (9 acres south of St. Helena).

GZ: We call it 887. It has sandy loam and some gravel. One of the things that is challenging is the scientific aspects; which is what it’s all about. When I started tasting, I discovered the front part of the vineyard has currant and raisin-y flavors from soils that are heavier. The flavors are more forward, and the fruit is not as dense as from the northern part. Here, there’s Santa Rosa plum, it’s fleshy and denser. In the southern end there’s black cherry, cassis, and it’s not as dense as the north. So I split it up into three blocks. But it takes me two to three years to understand a vineyard.

AG: Then there’s St. Helena Mountain (10 acres).

GZ: It’s the Cowen Ranch. Its further northwest at the base of the Mayacamas, with alluvial soils and lots of crushed rock. It’s also in three blocks. They never picked in separate blocks before. They do have consumers who like all three blocks of a St. Helena mountain Cab (but) we haven’t decided yet what we want to do. But some will be blended to make a St. Helena Mountain wine.

AG: Next is the Howell Mountain vineyard (7 acres).

GZ: Here, there’s Cab, Merlot and Cabernet Franc. It’s a challenge to make mountain fruit that you don’t have on the valley floor. Part if it is: how much water do you have? … We get a lot of small berries, bloom is later, harvest is much later – two, three

I personally know the sister-in-law of Dave Del Dotto and I recently visited the vineyards. It was truly an amazing, once in a life time experience. The wines I tasted are the best I've EVER had in my life. Once you've had great wine you don't want to go back. The wine done by the Del Dotto group is the way wine should be made. Almost a sense of what it was like centuries ago making wine. Spectacular tastes! Way to go Dave and Yolanda!
