"This is the way to go!"

I highly recommend the mini-autotitrators for both SO2 AND TA. They are very reliable, accurate, and quick to give result. The big bonus is being able to test everything in house!

A stable wine is a quality wine.


Portable Turbidity and Bentonite Meter


Clarify your wine so it’s signature taste, aroma, and appearance won’t change while in storage.

Our Portable Turbidity and Bentonite Meter offers a quick test to verify the risk of future protein haze formation; therefore, allowing you to confidently define the right amount of bentonite to add. This ensures you get the color and clarity you desire for a great wine every time.

Control dissolved oxygen for distinct quality.


Portable Dissolved Oxygen Meter for Wine Analysis


Get consistently accurate dissolved oxygen measurements to achieve the right balance in your wine.

Whether it's reduced or alternatively oxidized, the taste of wine can be dramatically affected by oxygen. Monitor DO for timely and effective micro-ox implementations and to ensure consistent process control and operation of equipment.

Know the basics for a better harvest

We realize that harvest season is the busiest and most critical period of the year for winemakers. Organizing the harvest and planning the work is vital to a successful and trouble-free vintage. Preparation for the analytical measurements relied upon to make winemaking decisions can sometimes be missed.

Visit our Winemakers’ Blog to making sure that you are ready for the season.

Quicker than a freeze test.

Tartrate stability in wine is very important. Much quicker than other methods, conductivity is a practical and reliable method to make sure your wine not only looks good, but tastes good too.

pH Testing Tips

Clean Regularly.

Depending on the nature of your samples, your pH electrode can become dirty or clogged resulting in slow and faulty readings. Regular cleaning will prolong the life of your electrode.

Calibrate Often.

To ensure your pH measurements are accurate, be sure to calibrate after extended storage, cleaning, and before use. Use fresh buffers that bracket your expected value.

Condition Always.

A dry electrode results in slow, incorrect measurements. Always use proper storage solution and be sure to fully cover the junction.
