A shift from quality control to quality design Quality control has always played a pivotal role in the production of wines. Global, national and local regulations stipulate permissible production strategies like the use of additives and processing aids, as well as labeling requirements for several components that may be present in a wine.

However, winemaking is a delicate process where the composition of grape juice and must, as well as unexpected changes during fermentation, clarification, racking or aging can quickly de-rail the development of a wine.

Time is of the essence when creating premium wines. Wineries have, therefore, relocated several aspects of quality control to onsite laboratories Figure 1 and established in-process analytical testing strategies that transform quality control into quality design.

With direct access to data on critical biochemical parameters of production, vintners can now rely on more than experience and lessons learned to maneuver the winemaking process. Thanks to onsite laboratories and advanced yet easy-to-use analytical instruments, what used to be occasional checks and partial glimpses into the status of a fermentation vat or aging in a barrel is now a systematic biochemical profiling of the wine at every stage of its evolution — from raw grapes to a bottle ready for sale.

Figure 1. Analytical wine testing commonly done onsite. Informed, on-time decisions make quality wines In winemaking, the outcome of every production stage is the starting point for the next. As such, at each transition, a vintner must decide exactly when to move to the next step and whether a batch should be carefully adjusted to keep it biochemically on track.

Data from analytical testing performed at each of these decision points arms the vintner with a detailed profile of their craft to better anticipate deviations that can spoil a batch and steer or even enhance the quality of the final product.

During the first production stages, knowing the sugar and organic acid content of grapes helps determine the best harvest time and optimize the mixture of grape varietals that will initiate fermentation with the right sugar-to-acid ratio to reach the target final gravity.

Additives mixed into must promote fermentation and control pH. Which additive, and how much to supplement so that pH imbalances do not jeopardize color, flavor and microbial stability , depends on knowledge of the organic acid and nitrogen content of must.

Similarly, dissolved oxygen and sulfur dioxide are monitored from fermentation through to bottling to keep oxidation and microbial activity in check, both of which lower wine quality.

Modern, advanced analyzers for wine testing are designed for the high wear-and-tear of a winery manufacturing site. Efficiently determining the moisture content and testing for microbiological contamination in must and juice To reuse must and juice, the level of moisture and potential microbiological contamination should be tested.

Applications: Moisture Determination Spoilage Detection Analytical QC Want to bring your testing in-house? Efficient tools for quality control testing of your most important ingredient—your grape harvest The overall flavor of your wine depends on the acidity and sweetness of your grapes, and the acidity in your grapes is determined by their moisture content.
