What is stars electrodialysis

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

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

    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


Stars electrodialysis economics

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


Stars electrodialysis how does it work

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)

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)


Stabilab predict tartrate stability

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,

Stars electrodialysis in operation1

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
