Benefits of yeast counting

  • Add a constant to the winemaking process – consistent fermentation from year to year

  • Ensure your commercial yeast are alive so you can pitch the perfect number

  • Diagnose fermentation problems during fermentation

  • Know what is on your grapes, save your vintage

Oculyze Fermentation Wine

Wine is greatly influenced by geographical and seasonal aspects. However, winemakers often don’t realize the potential of their harvest due to challenges during the fermentation. This is where the Oculyze Fermentation Wine comes in. Cell counts can be time consuming and when performed infrequently throughout the year, mistakes can often occur leading to increased risks with the results of your wine.

The Oculyze FW is a smart, technology-enabled solution to the age-old problem of manual yeast counting. The Oculyze FW combines a 400x optical magnification with cloud-based image analysis software to enable you to accurately, easily and instantly analyze yeast concentrations on-site before and during the fermentation process. No special expertise or training is required. Our automatic yeast cell counter is precise and more affordable than counting yeast through a microscope.

Starting at €999 for the hardware and €1.99 per analysis, it is a very small investment to ensure your vintage achieves the potential of your grapes. You can’t control the sun or the rain, but you can control your fermentation. Five minutes in the lab can have a bigger influence on your wine than five hours in your vineyard.

We analyze the same volume as in a counting chamber (hemocytometer) but are 10 times faster and have no human error. Additionally, yeast viability is determined by differentiating between live and dead cells with methylene violet staining.

An integrated separation of clumped cells allows an accurate analysis; budding cells are automatically identified and provided as a separate value.

Our data management system allows you to access all of your yeast concentration and viability results. Review your analysis history from anywhere, anytime.

View and analyze your measurements from any connected device. The web app allows you to generate customized reports, view historical data, track your yeast over time and increase statistical accuracy by creating averages of different measurements.

Thoroughly tested

“The results of the cell counting with the Oculyze system are very closely comparable with those obtained using a Thoma chamber… The Oculyze system does not require a laboratory microscope or trained staff… The Oculyze system is faster due to the automated measurement and analysis.”External validation by the Research and Teaching Institute for Brewing in Berlin (VLB)

Additional features

Methylene violet

You can choose between Methylene Violet and Blue for your viability measurements. We send methylene violet with every purchase. Methylene Violet can offer advantages; it performs better in growing phases of yeast cells (i.e. exponential and stationary) as well as for cultures with low viability and totally dead cultures.

Sharpness indicator

This feature improves image quality and helps guide you to find the sharpest possible image. As you begin your measurements and turn the microscope knob, you will see the sharpness indicator changing values, once you have found the highest value possible – you’ve found your sharpest image and you’re ready to capture!

Manual Counting

Oculyze FW includes the option to manually count your yeast. This function adds a counting grid to your yeast images to mimic a hemocytometer/Thoma Chamber. This also affords you the opportunity to see what other microbes are in your must!

Discerning Cells

The Oculyze analysis will report on the varying sizes of your yeast. In addition, the algorithm will also identifying the percentage of cells that are budding which can be an indication of good yeast health as well as the stage of fermentation. Finally, Oculyze analyses can identify clustered cells, a task most automated cell counters struggle with.
