Winemakers know, many of the quality improvements to wine each season, happen in the lab. Regular checks during production and being able to make quick decisions based on the results is key in achieving this quality – therefore, the accuracy and reliability of the data used to make those decisions is critical.
We have partnered with wine producers and bottlers for over 50 years to make complex quality measurements routine, reliable and accurate. Find out more about how we support winemaking before, during, and after fermentation using the resources on this page: Sign up for our email course to learn how to care for your instruments, request a poster to hang in your testing lab, review our selection of application notes, or watch the video below to hear from one of our customers.
What happens when good wine goes bad … and how can you prevent it?
Through pre-fermentation, fermentation and post-fermentation, the delicate balance of flavors in your grapes evolve, optimally to create a sophisticated, balanced flavor that your customers will love. Consistent chemical monitoring through each phase helps ensure that the expected flavor profile develops.

Articles on wine monitoring
Customers have an expansive choice of brands – a testament to the stark competition in the market. Succeeding in this crowded landscape means retaining customer loyalty by offering the same great wines year after year. The need to attain that level of consistency and reproducibility in production, despite the complex interactions that impact winemaking outcomes, has brought advanced analytical technology onto the manufacturing flare oor of wineries worldwide.
Ask wine connoisseurs about their favorite vintage and they’ll probably mention the aroma from the uncorked bottle, the color in the glass, and the complex flavors. However, unwanted oxidation, discoloration, and microbial growth during production and after bottling can compromise all of these characteristics, putting revenues and reputations at risk.
The art of winemaking lies in knowing how to use different grape varieties, yeast strains, and production steps to create distinctive styles that are recognized for their aroma, taste, and appearance. Those traits, however, result from complex interactions among the growing conditions of grapes, their biochemical makeup at harvest, the reactions that occur during fermentation, and the biochemical development of must, juice, and wine during processing. Any imbalances in these interactions during production—from vine to glass—can alter the outcome and decrease the quality and palatability of a wine.
