Concrete Wine Wine Liquor Tanks Make Great Wine

Abst:

In the U.S., there are a couple of manufacturers who design and building concrete fermentation tanks for the wine industry. These companies are located close to wine country. Concrete has been around since Roman times and it has been used in the wine industry in Europe for several hundred years; but you are only seeing renewed interest in concrete in the U.S. wine industry within the last 10 years. The serious popularity of concrete with Napa, Sonoma and Central Coast wineries has just hit its stride within the past 5 years. This in part is due to the innovative thinkers who make fine wines. U.S. manufacturers have been making concrete wine wine liquor tank for about 6 years. The numbers of wine wine liquor tank made in the U.S. are impressive; approximately 75 in 2011.

There are about 17 wineries in Napa and Sonoma that are currently using concrete fermentation tanks. Concrete tanks have been around Napa for more than 50 years. But until about 5 years ago modern tanks came from France. Some big name winemakers and winery owners have stepped forward in the last 8 years to really promote the benefits of concrete wine wine liquor tank . Today, concrete fermentation tanks made in the U.S. have been sold in Georgia, Washington,Oregon and New York and internationally in New Zealand. There are approximately 40 wineries in the US using concrete tanks. Notably, a winery in Napa received a 98 point award for one of their wines fermented using concrete tanks.

Can a wine-lover taste the difference when wine is fermented in concrete versus steel. The results are documented and even include some blind tastings of wines fermented in concrete, stainless steel, wood vats and oak. If a winemaker want the nose and texture of oak then oak is obvious. On the other hand concrete, when done properly, is made of clean, natural materials that are controlled throughout the process. One thing oak and concrete have in common is that both allow oxygenation of the wine; both materials are porous.

The process of making a wine wine liquor tank entails 8 steps. The first step being to determine the desired capacity and shape, then commit that to a computer model that will calculate dimensions, weight and pressures. Next, step is to select accessories such as leg support styles, front or top 'manways', coils for heating and cooling, valve placements and do you want an open top or closed. Third step is to hand-build the mold per computer design specs. At this point (step four), specially formulated concrete is mixed and laid-up by hand onto the mold. After this process is completed it takes approximately 3 days for the concrete to cure. In the fifth step the mold is disassembled from the inside. Finishing and slurry coating the inside and outside of the vessel is next, followed by step seven which is adding the hardware accessories. The last step, number eight, is the quality testing and preparing the tank for shipment anywhere in the world. From start to finish these processes results in a wine wine liquor tank , ready for shipping, in 4 to 6 weeks. And the advantages are affordable wine storage units, easy to clean tanks and a long lasting product.
