Winetech

What Winetech does

Winetech LLC is a Napa, California-based provider of mobile wine filtration and treatment services, founded in 1997 by Stefano Migotto and Valentina Guolo. The company operates two integrated revenue lines for the California wine industry: (1) on-site mobile services including crossflow filtration, lees filtration, 4EP-4EG (Brettanomyces) treatment, volatile acidity adjustment, smoke taint removal, ethyl acetate removal, and de-alcoholization; and (2) equipment sales covering the WT-U crossflow filter series, WT-U.V2 reverse osmosis and nanofiltration systems, the WT-UD2 alcohol removal unit, the WT-UD30 gas regulation system, KS/KA ion exchange systems, and the Prodox proportional in-line dosing unit. Underlying technology rests on membrane filtration—capillary crossflow membranes, semipermeable composite-film RO, and ion exchange resins—refined over more than 25 years of R&D across both Italian and Californian operations, with proprietary resin formulations for 4EP/4EG capture (developed in 2003) and smoke taint remediation (developed after the 2008 California wildfires).

The business model combines project-based mobile filtration services delivered directly to winery locations with capital equipment sales; pricing is quote-based and not publicly disclosed, with customers requesting quotes via [email protected]. Go-to-market is direct enterprise field sales targeting California wineries, supported by a lean core team of four named personnel (two founders, a sales and service manager, and a technician). The customer base is a single vertical—California wine producers—addressing spoilage issues including volatile acidity, smoke taint from wildfires, Brettanomyces contamination, ethyl acetate, and stuck fermentations. The company is privately held, founder-controlled, with no disclosed institutional investors, funding rounds, or M&A activity, and operates exclusively in the United States with its commercial footprint concentrated in California.

Products and services

• Crossflow Filtration Service Mobile service that moves wine flow across a membrane at high velocity to continually scour the surface and remove fouling materials, while wine and dissolved solids pass through the membrane. Targeted at California wineries needing sterile and clarification filtration.
• Lees Filtration Service Rotary Drum Vacuum filtration service for separating wine from lees (sediment), offering superior speed, production, and resultant quality compared to plate-and-frame filtration. Delivered on-site at California winery locations.
• 4EP-4EG Treatment Service Wine treatment service using specialized resin technology to remove 4-Ethylphenol (4EP) and 4-Ethylguaiacol (4EG) off-flavors caused by Brettanomyces yeast contamination. Developed in 2003 for California wineries.
• VA Adjustment Service Volatile Acidity adjustment service to control and reduce out-of-control VA levels caused by stuck fermentation, spoilage during fermentation, or increased VA during aging. Targeted at California wineries facing high-alcohol wine VA issues.
• Smoke Taint Removal Service Service using reverse osmosis technology combined with absorbent media to remove smoke-taint compounds including 4-Methylguaiacol (4MG) and Guaiacol (G) from wines affected by wildfire smoke exposure. Developed in 2008 for California wineries.
• Ethyl Acetate Removal Service Pioneering RO-based service using reverse osmosis technology and absorbent media to remove excessive ethyl acetate that imparts acetone or nail-polish remover aromas from wine.
• De-Alcoholization Service Alcohol removal service for restarting stuck fermentations, correcting out-of-balance wines, and improving wine quality through alcohol adjustment using membrane technology.
• Crossflow Filter Units (WT-U Series) Capillary membrane crossflow filters (WT-U1 through WT-U16) for total cleaning and sterile filtration of still and sparkling wines, cider, fruit juices, beer, and unclear fermented products. Designed for best flow, lowest fouling, and predictable filtration quality.
• Reverse Osmosis-Nanofiltration Systems (WT-U V2 Series) Semipermeable composite-film membrane systems (WT-U4.V2 through WT-U24.V2) for separation of water from total dissolved solids, with maximum sugar recovery, color concentration, and partial or total rejection of acidity and salts.
