WINEMAKING alysis systems are usually accessed as a ser- vice except by large wineries. Because it is less ionized due to its high- er pKas, loose RO preferentially removes malic acid over tartaric. For the same rea- son electrodialysis, which only removes ions, is not very effective in removing malic acid. This is its Achilles heel—it is not the tool of choice for those overly crisp Midwestern whites. An additional alternative selective membrane technology is currently being marketed by Mavrik Industries. CEO Bob Kreisher is frank about its proprietary na- ture. "We want winemakers to feel com- fortable with what our process does, but we worked hard on developing a system that works well, and we don't want to give away essential information to our competitors," he said. Mavrik was nonetheless quite open to Cross-flow clarification is emblematic of a dizzying array of new membrane technologies sweep- ing the wine world on finished wine, even post-ML. Besides producing superior wines, electrodialysis can trim your energy bill by more than 25%. A system with an output of 200 gal- lons per hour costs upwards of $200,000. Because of its high capital cost, electrodi- my observing what their system does, and I got a firsthand look at the de-acidifica- tion of a 2010 Cabernet. Mavrick's technology is reportedly based on an acid-selective membrane that passes both molecular and ionized spe- cies. This is big news, greatly simplifying our lives because we no longer need to pay attention to ionization pH and malolactic Transporting the Wine Industry to a Greener Future Yandell Truckaway, Inc.
