Heritage Barrels inks sales deal with concrete tank maker Vino Vessel

Heritage Barrels“The value of concrete as a fermentation and storage vessel has been evident for centuries,” said John Schilter, managing partner of Heritage Barrels. “The concrete tanks from Vino Vessel allow us to offer another superior tool to our wine producing clients that complements the wood and stainless steel products they already use.”

NAPA — Napa-based Heritage Barrels, LLC, is representing Paso Robles-based Vino Vessel, Inc.’s complete line of concrete tanks in the U.S., Canada and Mexico, except for San Luis Obispo County.
Heritage Barrels sells high-end oak barrels and vats and said it has seen demand for concrete vessels grow throughout North America.
“We’re already working with some of the top winemakers in the Central Coast, and our partnership with Heritage Barrels allows us to showcase our concrete vessels to an expanded network of winemaking clients throughout North America,” said Micah Utter, president and chief executive officer of Vino Vessel.
Since 2007 Vino Vessel has been making concrete fermentation and storage tanks for red and white wines, ranging in size from 70 to 1,300 gallons. They have been used in production of many top-rated wines, including Booker, Chronic Cellars, Linne Calodo, Peachy Canyon and Stolpman Vineyards.

Concrete Evidence

More California producers are trying concrete fermentors and tanks

Saxum's Justin Smith likes his dirt. His James Berry Vineyard on the west side of Paso Robles was once an ocean floor, with fossils of whale vertebrae and distinctive limestone that help his grapes retain acidity as they ripen. When Smith visited Bordeaux and found out Ch√Ęteau Pontet-Canet incorporated some of their vineyard earth into their concrete tanks, he knew he wanted to do the same.

Smith sent some of his calcium carbonate-rich rocks to Sonoma Cast, a Petaluma-based concrete specialist. The rocks were ground into a powder finer than sand, then tested to figure out how much could be mixed with concrete and produce a tank with structural integrity. The customized aging tanks will be put into rotation later this year. Sonoma Cast founder Steve Rosenblatt is excited by the project. “It’s putting terroir into the tank."

But Smith isn’t counting on his wine tasting like dirt. Concrete is thought to be a neutral vessel for wine—not imparting flavors the way a barrel does—and Smith insists his idea is just conceptual. “Does the fact that our vines are going into rocks that were once the ocean floor and in turn have tons of fossils in them make the wine taste better? Not directly,” said Smith. “Does aging the wine that those vines made growing in the fossil-rich rocks make for a better-tasting wine? Not directly. But is it cool as hell? Damn straight it is!”

Smith’s terroir-tank project is unusual, but California winemakers working with concrete is becoming common. Concrete vessels aren’t new--they have been part of winemaking for hundreds of years. While they’ve been used consistently in Europe alongside wood vats and stainless steel tanks, in California they fell out of favor.

Interest in concrete sparked again in recent years, but it took off slowly because the tanks were only produced in France, and shipping a 4-ton container overseas made them cost-prohibitive for most vintners. That changed when California companies added concrete winemaking vessels to their lineup. Since 2007, more than 400 California-produced concrete tanks and fermentors have been produced for the cellars of Staglin, Linne Calodo, Cliff Lede, Continuum, Wind Gap, Sandhi and dozens of other wineries. Many more are on their way.

This was made possible because interested vintners approached two concrete companies, both of them led by wine lovers. Micah Utter is an artisan concrete maker, known for decorative patios and walkways in Paso Robles, who has dabbled in home winemaking. He founded the Vino Vessel branch of his business in 2007. Sonoma Cast’s Rosenblatt owns a vineyard in Sonoma and had a successful business designing and making sleek, modern concrete countertops, sinks and a furniture line sold at Restoration Hardware. Sonoma Cast added winemaking vessels to their lineup in 2010, using a proprietary concrete mix that gives them the flexibility to make concrete in an array of colors and textures.
As far as functionality, concrete lies somewhere between stainless steel and oak barrels in the tool chest of a winemaker. Like stainless steel, they are neutral containers (though some claim they can impart a mineral note into a wine, depending on the type of grape and length of exposure). One of concrete’s biggest selling points is thick walls, effective at stabilizing temperatures, especially useful during fermentation. “I’ve never worried about temperature during fermentation with concrete,” said winemaker Jeff Cohn.

Like a barrel, concrete is also known to soften a wine’s texture, though the reason why is up for debate. “They breathe,” said Rosenblatt. “But the air doesn’t come from the outside.” A tank’s interior surface can feel as smooth as glass, but there are actually microscopic pockets and nooks created by the concrete curing process. When full of wine, these nooks slowly release oxygen. Utter agrees with this concept, but he also suspects that the oxygen makes its way through the porous walls. Winemakers who want to avoid oxygen can have their tanks lined.

Concrete is also customizable. “Winemakers are very particular,” said Utter, who estimates 40 percent of his units are made to order. Modifications include optional ports for racking and cleaning, heating and cooling coils and, of course, size. Utter sells a 70-gallon “tester” barrel for winemakers to experiment with, but most tanks range from 400 to 2,000 gallons, cost from $10,000 to $30,000 and have a 20- to 30-year lifespan. In contrast, a standard barrel is about 60 gallons, the best ones costing upwards of $1,000, and only last a few years before losing their potency.

One of the biggest choices is shape—there are cubes, cones, pyramids or the stout “hippo” shape. One of the most popular forms for a fermentor is an oversize egg, which many believe create a natural vortex. As fermentation gasses are released, they are forced to move from the bottom of the tank to the narrow opening at the top. The movement eliminates or reduces the need for lees stirring and pump-overs. “I can’t tell you if it’s actually moving by looking at it,” said Cohn, “But I can tell you the lees don’t settle out. They stay afloat.”

Smith’s vineyard-customized concrete will look like an inverted egg, or amphora shape—its narrowing base ideal for collecting sediment. It’s going to be years before wines aged in Smith’s containers can be tasted to see if they have any effect, but in the meantime, Smith is happy to see his idea come to light. With more California winemakers experimenting with these containers, more innovation is bound to happen. Rosenblatt has a suggestion. “Concrete bottles are next,” he said with a grin.
