After harvesting a bumper crop, laboratories need precision in their quality control. One indispensable tool for maintaining consistency and excellence in winemaking is the use of automatic analyzers in the laboratory. Admeo’s partners at Biosystems sophisticated instruments provide real-time actionable data on key parameters, ensuring that each lot of grapes and wine meets the highest quality standards. Testing each barrel is easy with automated analysis. In this article, we'll explore how to use automatic analyzers to streamline quality control during a bumper crop. 

Select the Right Analyzer 

Through conversation with us about your specific winemaking needs, choose an automatic analyzer which is known for accuracy and reliability. The SPICA, Y200 and Y400 are all excellent options to consider for additions to your laboratory. 

Malic and Lactic Acid 

Malic acid is essential in a winery during a bumper crop as it provides valuable insights into the wine's tartness and aging potential. High levels of malic acid can contribute to a crisp and refreshing taste in white wines, but its presence in excess can make the wine overly acidic. Monitoring malic acid allows winemakers to decide whether malolactic fermentation is necessary to convert malic acid into milder lactic acid, thus improving the wine's balance and enhancing its aging potential. 

Glucose and Fructose  

Measuring sugars directly impacts the potential alcohol content and fermentation process. Monitoring glucose and fructose levels provides winemakers with valuable information about grape ripeness and the sugar-to-alcohol conversion during fermentation. Accurate measurements help winemakers ensure the desired level of sweetness or dryness in the final wine product. This precision is vital for crafting wines that meet the desired flavor and aroma profiles. 

Acetic Acid, pH and Molecular sulfites 

Acetic Acid is a crucial parameter to measure because it directly impacts the wine's quality and stability. Excessive acetic acid levels can lead to an unpleasant vinegar-like aroma and taste in the wine, diminishing its desirability. Monitoring acetic acid levels allows winemakers to take timely corrective actions, such as implementing effective sanitation practices, to prevent spoilage and maintain the wine's integrity.  

If acetic acid levels rise too high due to unwanted microbial activity or other factors, it can result in an increase in the wine's pH. A higher pH can, in turn, shift the equilibrium of sulfite species towards molecular sulfites (SO₃²â») rather than bisulfite ions (HSO₃⁻), which are more effective at preventing oxidation and microbial growth. Therefore, the presence of acetic acid and its influence on pH can indirectly affect free sulfite levels and the prevalence of molecular sulfites in wine. 

Measuring pH is of paramount importance in a winery for several reasons. First and foremost, pH directly affects the chemical stability of wine. A balanced pH level is essential to ensure that the wine retains its desired color, aroma, and taste characteristics. High pH levels can lead to color instability and the potential for spoilage due to microbial growth. Conversely, low pH levels can result in excessive acidity, making the wine taste harsh and unbalanced. By carefully monitoring pH, winemakers can make informed decisions on the addition of acid or other adjustments to maintain the wine's quality and stability throughout the winemaking process, especially during bumper crop years when variations in grape characteristics can be more pronounced. 

Incorporating automatic analyzers into the laboratory is invaluable when managing a bumper crop. These high-tech tools provide precise and real-time data, empowering winemakers to make informed decisions and maintain the quality and consistency of their wines. By investing in the right analyzers and implementing best practices for their use, vineyard and winery operators can navigate large harvests with confidence, knowing that their wines will continue to meet the high standards expected by consumers and wine enthusiasts.
