Tannins are a group of phenolic compounds found naturally in the skin, seeds and stems of grapes used in wine, as well as in the barrels where wine is aged.
Traditional methods of tannin determination require the preparation of specific reagent solutions and are demanding in time and preparation. The Tannins kit is based on the methylcellulose precipitable method (MCP), improving its usability and stability. The MCP technique captures both tannin types and pigment-bound forms, giving a clearer picture of a wine’s structure and future evolution.
Our analyzers use UV-Vis spectrophotometry, which measures light absorption at specific wavelengths associated with tannins. This provides an objective, accurate and reproducible measurement of tannin content, allowing the winemaker to control its extraction during maceration, its evolution during aging and its influence on the stability and final quality of the wine.

As we are in bottling season, free sulfite deserves extra attention.
Free SO₂ is your last line of defense against oxidation and microbial spoilage. Levels can shift more than expected after racking, blending, or filtration.
Before bottling, make sure to:
• Measure and confirm free SO₂
• Adjust based on pH and desired molecular SO₂
• Recheck after final additions and just prior to filling
A few ppm can make the difference between a wine that evolves beautifully and one that fades prematurely.
Please reach out if you’d like to chat about automated solutions for checking free sulfite.
Precision and repeatability are essential in wine quality control.
Steroglass' FLASH2 automatic titrator performs rapid and reliable analyses on key parameters such as pH, total acidity and free and combined sulfur dioxide, with automatic equivalence point detection.
A compact, intuitive instrument that is perfect for improving efficiency in wine laboratories, reducing errors and working times.

How do you ensure that your wine is ready for bottling, cold stable and free of the dreaded tartaric acid crystals?
For some wineries getting this certainty can be a nightmare both in terms of time, costs and space.
With EasyCheck from Admeo you get the all-important confidence before bottling ensuring your wine is cold stable.
What’s more, EasyCheck also provides precision temperature control meaning accurate, repeatable results.
With EasyCheck you get your data in minutes, not hours and get real-time results that could take weeks off your QC process.
WiVi Central Coast is next week! Are you looking forward to the trade show as much as we are? 🍇
What are your labs' needs around QC? Please reach out with questions, we would love to speak with you.
How much do we appreciate feedback from our clients? A ton!
