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.

2008 Iron Hill Vineyard Zinfandel

“Topographically speaking, the amphitheater like vineyard, sitting at a steep 55° angle, profoundly influences the depth and concentration of the grapes. The rocky, volcanic soil provides just enough nutrients for the vine’s struggling existence. As in the past, this wine demonstrates the heights to which Zinfandel can go.” – Jeff Cohn

Tasting Notes

This Zinfandel is an experience of terroir. Aromatics that express the loamy earth tones are intertwined throughout. Then blackberry jam with touches of wild raspberries starts to explode from the glass. At this point a subtle touch of lavender becomes the seductive focal point of the aromatics. The flavors of this wine are very much a mirror image of its aromas, but hints of Herbes de Provence, and the sweet smell of the sunshine after spring rain.

Varietals: 100% Zinfandel
Appellation: Sonoma Valley
Alcohol: 15%
Production: 180 cases

This distinctive and appealingly exotic Zin features aromas of smoky black raspberry that follow through to zesty, complex flavors of peppered beef, black cherry and toasted anise. Finishes with racy, rustic tannins. Drink now through 2017.— T.F.

Robert Parker's Wine Advocate - 92 points

Also a winner, the 2008 Zinfandel Iron Hill Vineyard was aged completely in French oak. Its dense plum/garnet/purple-tinged color is accompanied by a wine with a full-bodied mouthfeel, peppery, garrigue, black cherry and meaty notes, and a full-bodied finish.

The same can be said of the 2007 Zinfandel Iron Hill Vineyard (99 cases). This offering exhibits a more floral character as opposed to blockbuster red and black fruits.

Not for every taste, this is fairly Rhône-like, though it’s loaded with personality. Offers the spicy, smoky meat aromas of an Italian deli, with concentrated, ripe wild berry, blueberry and licorice flavors that finish on a briary note. Drink now through 2012. 127 cases made.
Dark ruby/purple-tinged, medium-bodied…possesses peppery forest floor, underbrush, and briery, cherry-like fruit characteristics. It should be drunk over the next 3-4 years.
This wine reveals an even more saturated ruby/purple color as well as impressive levels of rich, briery, concentrated, sweet fruit (raspberries, cherries, blueberries), plenty of pepper, a distinctive, earthly terroir component, and a spicy, full-bodied finish with tart acidity providing uplift. It is a classic, high octane, gorgeous Zinfandel to drink over the next 5-6 years.
