Interview with Jeff Cohn

“Wine should have a personality. It’s something that should come from the wine maker’s heart.”

Established: 1996

Patch spoke with founder and wine maker, Jeff Cohn. 

How did you get started in wine making? My first job in the wine industry was with Boordy Vineyards in Maryland. I did everything — picked fruit, cleaned barrels, bottled wine, cleaned toilets — whatever they needed done.

You really started from the bottom up. Oh, I started below the bottom! But I learned. It gave me great opportunities.

Going to Rosenblum was the greatest opportunity. After I got a masters in agricultural chemistry with an emphasis on oenology from Fresno State, I took a job with Rosenblum where I had worked as a harvest intern. I started as a lab assistant, then I became head of lab, then I was in charge of white wine, then red, then both. Finally I became the vice president of winemaking.

I can’t say enough nice things about Kent Rosenblum. As with every wine maker, we wanted to make the greatest wines possible. So we discussed how were going to get to the next level with our wines.

He gave me room to create and play. I thought we should go in a certain direction and Kent was very open to it. We spent a fortune on barrels, did a lot of research and experimentation with yeast and fermentation styles. We achieved some great things. The wines we created were wow! wines — with explosive flavors and aromatics that no one else was doing at the time. It was an adventure! I feel blessed that I had the chance to do it.

What special skills do you need to be a wine maker? I had a pretty decent palate, but I don’t think it’s just your palate. It’s partially your palate, but it’s the ideas in your head.

I think anybody can make wine. To make great wine, there’s something else going on. Here’s an analogy: anybody can play the piano but only a few can make music. Or remember the movie, Ratatouille? Anybody can cook but only a few can make something special.

So what happens when you blend a new wine? It’s not a formula — 75 percent Zin plus this should make this wine great.

In my head, I have a vision of what I’m trying to achieve. I don’t consider myself the most creative person in the world, but I know what I’m trying to achieve. I know what this particular vineyard should be bringing to the table. It’s the potential of that particular fruit, whether it’s got more brambly notes or more chocolate overtones. It’s about combining textures and flavors.

The wine is hitting the front palate, then building in the mid-palate and then flowing to the finish. But maybe something’s missing. It’s my job to make that bridge happen — to make the flavors explode.

After you started JC Cellars in 1996, how long did it take you to establish the brand?  About a year. In 1996, there weren’t so many wineries. There are too many out there now. So many of the wines taste the same.

Wine should have a personality. It’s something that should come from the wine maker’s heart.

What wines is JC Cellars best known for? I’m known for my Rhone wines and zinfandels.

When did you open the tasting room? In 2007. I really wanted people to come taste my wines. Also, I wanted people to see us working, to be part of the wine-making experience. In addition to this one here in Oakland, we have one in Napa that we share with ten other wineries.

Most people don’t think of Alameda as the heart of the California wine industry. Why did you choose to stay in the area when you launched JC Cellars? I had many choices of places where we could have gone after I left Rosenblum. Even though there’s lots of people on the Island, it’s a very small-feeling community. Everybody knows everybody. I wanted to raise my family in a place that felt small and safe. I wanted my daughters to have a sense of community.

2004 Rockpile Vineyard Syrah Haley's Reserve

“The Rockpile AVA produces outstanding wines, and this is our 4th vintage from the Rockpile Vineyard. With a strong coastal influence, temperatures are kept moderate during the day and cool at night. At 2000 feet, it has the highest elevation in the region. This puts it above the fog line giving the vines more sun exposure, thus better ripening.” – Jeff Cohn

Tasting Notes

Opaque black/purple color as well as a gorgeous nose of blackberry liqueur intermixed with melted licorice, smoked meats, acacia flowers and a talcum powder-like stony minerality. A wine of great depth and concentration, Rockpile Vineyard Syrah exhibits extracted fruit character followed by JC Cellars signature supple mouthfeel.

Varietals: 100% Syrah
Appellation: Rockpile
Alcohol: 15.3%

2007 Rockpile Vineyard Syrah Haley's Reserve

Robert Parker's Wine Advocate - 91 points

The 2007 Syrah Rockpile Vineyard (458 cases) needs some additional bottle time. Meaty, roasted herb, espresso, blackberry, and chocolate aromatics ooze from the glass of this black/purple-colored wine. Intense, full-bodied, and loaded with tannin and extract, it should drink well for a decade.

Intense and vibrant, with rich, full-bodied blackberry, wild berry and blueberry fruit that's deep and concentrated, focused and pure, ending with a long, persistent finish that gushes with fruit and is supported by ripe tannins. Drink now through 2015. --J.L.

From a 2,000 foot elevation vineyard in the Rockpile area (which is now entitled to its own appellation name), the sensational 2006 Syrah Rockpile Vineyard exhibits notes of camphor, acacia flowers, and blue as well as blackberries.  This full-bodied, multilayered, rich, super-concentrated Syrah ca be drunk now or over the next decade.This is a dazzling example of this new AVA.

2_puffs 91 points 2006 JC Cellars Rockpile Vineyard Syrah 

The Rockpile region is not likely to be the place where Syrah runs into limits and seeks polish, but this wine, admittedly both bold and very much on the rugged side, still possesses nicely formed blackberry fruit, complementary oak, and notes of dark soils, tar and dried spices.  It is about equal in weight to the wine above [2006 JC Cellars Stagecoach Vineyard Syrah] but is noticeably fleshier and chewier in texture.  Withal, this one probably drinks younger than its mate simply because of its fruit is a trifle more open at its heart.

Leisure • Domestic Red Wine

Jeff Cohn, the former winemaker at Rosenblum Cellars—a producer of particularly fine vineyard-designate Zinfandels—stepped out on his own in 2006 to devote his full energies to JC Cellars.  His modus operandi resembles that of his former employer, Kent Rosenblum: Establish relationships with the finest growers across the state to produce modest quantities of immodestly great wine.  Although Cohn produces more than 20 different Rhône-style wines in his Oakland, Calif., warehouse-cum-winery, the Syrahs he has sourced from the Rockpile Vineyard—a rugged scrap of terrain situated on a peak above Lake Sonoma—are his masterpieces.  The JC Cellars 2006 Rockpile Vineyard Haley's Reserve Syrah is as intense and generous as the vineyard is spartan and bleak.  The scent of wildflowers greets the nose, while unctuous brambleberry juice and concentrated black-cherry liqueur wash over a deep core of ripe tannins. —B.A.

Floral, dried berry, soy and sage aromas are rich and intense, with spicy, cedary oak and loads of blackberry and currant fruit that’s pure, focused and firmly structured. Drink now through 2012. 259 cases made.
Consistently one of my favorites JC cellars wines is their Syrah Rockpile Vineyard. The 2004, 100% Syrah aged in French oak boasts an opaque black/purple color as well as a gorgeous nose of blackberry liqueur intermixed with melted licorice, smoked meats, acacia flowers and a talcum powder-like stony minerality. Powerful (16.3% alcohol) with superb underlying acidity and layers of richness, this is a blockbuster Syrah that should drink well for a decade.
This formidably-endowed Syrah, dense purple-colored offering boasting a sumptuous bouquet of vanilla, blackberry liqueur, cherries, licorice and peppery spice. Massive in the mouth, but well-balanced, with impressive purity, layers of fruit and glycerin, and a rich, long finish, this backward Syrah need 1-3 years of bottle age, and should keep for 12-15.
A delicious orchestration of ripe, rich fruit, built around a core of blackberry, blueberry and boysenberry fruit, which a dash of spice, cedar and kirsch, ending with firm but ripe and supple tannins, ending with a long, persistent finish. Drink now through 2010.
They don't get much bigger, richer, fuller, deeper or riper than this absolutely fully stuffed offering from Jeff Cohn. Never on to eschew the density and extract available in the big reds, Cohn has here delivered a blockbuster that will win friends among those who can accept the weight and complexity in this one without minding its substantial (15.9% alcohol). For, make no mistake about it, this wine trades its amazing intensity for its spiking heat in the finish. It will certainly age well, but it is likely to show best in its first decade.
This blockbuster (from a red soil vineyard planted at 2,000 feet) boasts a gorgeous perfume of boysenberries, blueberries, blackberries, lavender, toast and licorice. Full-bodied, with a voluptuous texture in addition to dry tannins lurking behind the extravagant fruit and concentration, this terrific Syrah should hit its prime in 1-2 years, and last for a decade.
High-toned, superrich and fleshy, with layers of plush blackberry, boysenberry, fresh earth, mineral, mocha and toasty oak delivered in a seamless package, finishing with an elegant burst of ripe fruit. Drink now through 2009.
