  1. TARTRATE STABILIZATIONvia STARS/Electrodialysis

  2. What is STARS/Electrodialysis STARS/Electrodialysis clockwise from top left • STABILAB predictive & verification test (DIT/ISTC50 • STARS/Electrodialysis 3,200 gal/hr • RO 70%+ waste water reduction

  3. STARS/ED - Annual Volumes Tartrate Stabilized • Machines currently in service: ED800 (ED = Electrodialysis / 800 = gallons per hour) Terravan, CA                                      ED400 Chandon, CA                                      ED1600 St Supery, CA                                     ED800 Winesecrets, CA                              ED800 Canadian Winesecrets, CAN        ED600 Oregon Winery ED800 ChtSt Michelle, WA                        ED1600 Vincor Ontario, CAN                       ED800 Diamond Estate, Ontario, CAN   ED800 Oenodia, CA                                       ED800 (Rental unit) • Average yearly volume processed with above machines: ~ 5,000,000 gal • Average yearly volume for Mobile Service units (Winesecrets) : ~1,000,000 gal • Additional units for 2012: 3 wineries (2- ED800 & 1 ED2400) with annual volume of ~ 3,500,000 gallons • Total approximate annual volume tartrate stabilized: ~ 8MM to 10MM gallons • Annual Global Production: ~ 200 MM gallons or ~ 3% of global wine volume • ~ 10% sparkling • ~ 40% red • ~ 35% white • ~ 15% rose

  4. STARS/Electrodialysis Economics If you own a STARS unit: • Operations cost $ 0.03-0.05 per gallon includes membrane replacement • Process from 800 up to 3,200 gallons per hour • Investment $ 200,000 to $ 800,000 Cold stabilization by refrigeration costs $ 0.07-0.16 per gallon. 2 to 3year Return On Investment, at today’s energy rates. Utility rebates are improving this further

  5. STARS/Electrodialysis - How does it work? Continuous operation, controlled by reduction of conductivity from tartrate removal. No additives are used to inhibit precipitation or stabilize the wine. System consists of 4 steps/processes: • Determine reduction of conductivity to achieve stability via STABILAB • Pass wine between the membranes to reduce conductivity by removing tartrates via STARS. • Monitor conductivity to ensure stability via onboard conductivity meter • Verify wine stability via STABILAB (ISTC50 test)

  6. STARS/Electrodialysis – DIT -> STARS -> ISTC50A comprehensive approach to Tartrate Stabilization 2-Probe STABILAB with Heating bath for DIT test to predict tartrate instability, STARS processing rate and confirmation test - ISTC50, post STARS treatment (DIT- Degree of Tartaric Instability) (ISTC50- Critical Tartaric Stability Index) STARS/Electrodialysis ED3200 3,200 gallon per hour system Semi-automated operation Can run 24 hours per day with 2 CIP’s each taking about 1.5 hrs. (~20hrs/day)

  7. STABILAB: Predict Tartrate Stability • Based on conductivity variation over 4 hrs. • Wine samples are tested at -4°C / 24.8°F and seeded with KHT • Calculates drop in conductivity required for an “infinite time” or “absolute wine stability” • Provides drop in conductivity rate (DIT) for STARS treatment (processing rate in %, e.g., 18%, 22%) • Verifies STARS treated via ISTC50 test (6 days @ -4°C or 24.8°F) • All results are stored in software, can be printed and converted to PDF files • Patented tests (INRA / EURODIA) • Used in major labs throughout Europe and North America • Sarco Laboratories, ETS, Napa Valley Think Tank,

  10. STARS/Electrodialysis in Operation

  11. STARS/Electrodialysis in Operation • Automated operation, regulated by conductivity or pH • Onboard / Inline conductivity meter • Hand-held conductivity meter for verification (included) • 12hr run cycle after which a CIP is required • Single pass, tank to tank processing • Pre-filtration at <5 μm required, preferably via XF • Wine should be at cellar temperature • No wine loss (0.5% to 1.5% of total wine volume) • No oxygen pick up • Time saving: up to 64,000 gal/day or more • Power consumption: 0.009 KWh/gal vs. 0.8 to 1.0 KWh/gal for cold stabilization • Water consumption: 3% to 5% of total wine volume – not included is the water used for cooling tower
