Sea Change Coming To California Winegrap…

California’s coastal areas, foothills and the Lodi/Delta region are expected to add acreage over the next few years, while the San Joaquin Valley declines. (Source: Allied Grape Growers) If you asked typical American wine consumers where most winegrapes in the U.S. are grown, they would almost certainly say California, as the state produces about 90% of the nation’s total. And if you asked where in California most of those winegrapes are grown, they would likely cite the well-known counties of the North Coast, such as Napa, and to a lesser

Non-conventional Yeast Species for Lowering Ethanol Content of Wines.

Rising sugar content in grape must, and the concomitant increase in alcohol levels in wine, are some of the main challenges affecting the winemaking industry nowadays. Among the several alternative solutions currently under study, the use of non-conventional yeasts during fermentation holds good promise for contributing to relieve this problem. Non-Saccharomyces wine yeast species comprise a high number or species, so encompassing a wider physiological diversity than Saccharomyces cerevisiae. Indeed, the current oenological interest of these microorganisms was initially triggered by their potential positive contribution to the sensorial complexity of

Native Plants Reduce Need For Vineyard Water, Pesticide Usage

Scientists in eastern Washington are finding drought-tolerant alternatives to roses at the end of vineyard rows that not only save on water, but increase predators of pests that are harmful to crops. Roses traditionally have served as not only beautification in vineyards, but were once used to detect the onset of diseases such as powdery mildew, which affects roses before grapevines. But those roses also require a lot of water, which isn’t in abundant supply in many parts of Washington. The Washington State University Wine Science Center in Richland, WA,

CONCENTRATION CONTROL IN FILTRATION SYSTEMS, AND ASSOCIATED METHODS

Concentration control in filtration systems and associated methods are generally described. Streams originating from upstream filters and having similar concentrations of a target minor component and/or similar osmotic pressures can be mixed and subsequently filtered within additional filters. Certain embodiments comprise recycling an output stream produced by a filter to a filter feed stream, wherein the output stream and the filter feed stream have similar concentrations of a target minor component and/or similar osmotic pressures. Such strategic mixing and/or recycling can reduce the amount of energy and/or the amount of

Synthetic wine made without grapes claims to mimic fine vintages

“We can turn water into wine in 15 minutes.” So claims the Ava Winery, a San Francisco start-up that is making synthetic wine without grapes – simply by combining flavour compounds and ethanol. Mardonn Chua and Alec Lee came up with the idea while visiting a winery in California’s Napa Valley in 2015. There, they were shown the bottle of an iconic wine, Chateau Montelena, which is famous for being the first Californian chardonnay to beat French contenders at the Paris Wine Tasting of 1976.
