WINEMAKING status. Colorless, flavorless permeate from this membrane is passed through a weak anion exchange resin where malic, tartaric and lactic acids are retained. A cation- exchange column can also be employed to exchange potassium for H+ , with the ef- fect of re-acidfying the permeate prior to recombination. In this way, buffer capacity is removed, and pH and TA can be adjusted more or less at will. Although I cannot claim to fully grasp the details of Mavrick's pro- prietary magic, I can at least attest that the Cabernet came through it with flying colors and no discernible aroma loss. As Mavrick refines this technology, it may very well be the toy of choice in regions plagued by high malic acid. Back in sunny California, extended hangtime often results in high-potassium wines that resist pH adjustment with tar- taric. A new approach to acidification of high-pH wines and musts now be- ing pioneered by Eurodia uses a bipolar membrane on the cation side to exchange potassium ions for protons, thus raising the TA. Unlike tartaric acid addition, this lowers pH without increasing buffer ca- pacity. The membrane works much like Consumers want natural, but above all, they want tasty wines and won't settle for less. a cation-exchange resin, removing potas- sium ions in trade for H+ , but without the stripping of flavor elements that occurs during direct contact of wine and resin. Bipolar anion applications may also be on the horizon. The bottom line Any reporter loves a scoop. In preparing this article I was treated to a generous handful of new technologies that prom- ise to transform American winemaking in an era of climate change, up-end modern winemaking precepts and render current teachings obsolete. Yet there is no bottom line to report. To a man, technology developers waffled and temporized concerning release dates, performance, efficiencies and capital costs America's Choice For Vineyards, Wineries & Orchards Since 1986 Vineyard Supplies No Vines...

The complex and peculiar machinations of TTB approval are an uncharted minefield through which wineries must walk with care and do their own homework. We are smack in the middle of an era much like the 1960s, when a tsunami shift from Ports and Sherries to table wines left us in total ignorance. Today we are completely unprepared for the im- pact of de-acidification capabilities even their providers have yet to fathom. Smart postmodern winemakers throughout the country and their state-sponsored aca- demic partners are well advised to place a high priority on understanding and evalu- ating the diverse menu of options soon to be thrown on our plates. In all candor, this article provides no dependable Consumer Reports purchase guide to de-acidification. In its stead I have sought to lay the groundwork for such an evaluation by tracing a roadmap of the options we must immediately get smart about.
