“Using OenoFoss obviously improves the winemaking process. In one minute you have a result and you know if you can influence it.”

Winemaker Ramon Martinez Matute at Grupo Yllera, Spain explains how the OenoFoss gives him more power to influence the winemaking process from start to finish.


  • Multiple results in 2 min.

    FTIR analysis involves infrared scanning of must, fermenting must, or wine samples. OenoFoss can be customized from more than 30 calibrations and displays results on quality parameters in just 2 minutes.

  • Unlimited Analysis

    No reagents and extra costs
    Improve wine making and wine quality with more analysis
  • Keep Track of Barrels & Tanks

    Results are automatically stored on a PC and history views display developments over time. You also have the option to customise your software settings in order to reflect your operations in terms of wine types, sample identification.
