Instant knowledge for better business with wine quality analysis

Rapid testing of a wide range of parameters in must, must under fermentation and finished wine secures quality while supporting an agile approach to winemaking

Wineries

 

Making the right decisions in winemaking has never been easy. Even so, the events of recent years have put the business under unprecedented pressure. Beyond considerations related to the pandemic, climate related challenges are only set to grow with extreme weather already affecting growing conditions in many regions. Against this backdrop, the constant challenge of making great wine consistently year-after-year remains.

While sensory perception will always be at the heart of decision-making, rapid wine quality analysis adds a valuable new perspective that helps to improve both quality and business. Just as wine held to the light reveals valuable information to a trained eye, so a small sample of wine tested with an easy-to-use instrument in less than a minute pours forth a wealth of information that puts winemakers in full control of the winemaking process.

The availability of analytical data allows better decision-making throughout the winemaking process leading to more consistent quality and ultimately better business through improved brand and economy. Tradition supported by reliable test data is a unique partnership that paves the way for even higher levels of quality wine throughout the industry.

Insights add value

 

 

Grape maturity

Track quality from the field and know when to pick to ensure optimal grape maturity.

Grape recieval

Check grape quality, segregate for best use of the harvest and decide correct payment.

Fermentation and ageing

Track alcoholic and malolactic fermentation and react in time to avoid potential issues.

Blending and bottling

Ensure stability of wine for bottling and measure finished wine for correct blending, bottling and documentation with minimal administration work.

 

Make smarter harvesting decisions and pay the right price for grape deliveries

 

 

Rapid analysis of grape must allows you to follow the development of grape maturity from the start of the veraison period through to harvest. Individual grape pulp parameters can be followed including fructose, glucose, total sugar, tartaric acid, malic acid and total acidity.

 

The on-the-spot objective measurements help you to achieve the balance you are looking for between sugars and acids. You can get a complete picture of ripeness, both in terms of the physiological maturity of the grapes and through insight into quality characteristics that contribute to the final quality of the wine.

Avoid nasty surprises with up-front insight into grape soundness

 

Spot potential disorders before they affect your wine
Rapid analysis of grape quality is not only a way to see what is going right. It is also valuable in tracking the interaction between microorganisms and their media – the grapes. The availability of frequent test data helps to avoid the mistakes and costs associated with poor quality grapes.


How it works
Each microorganism consumes metabolites from the grape (sugars, amino acids, etc) and produces microbial metabolites (ethanol, glycerol, etc). For instance, yeast transforms sugars to ethanol which is the fundamental process in vinification. At harvest, no ethanol or other microbial metabolites is expected and, indeed, their absence is a prerequisite for grape soundness. With FTIR, it is possible to measure those metabolites that may be present in high concentrations. In addition, the presence of the individual metabolites at different levels supplements the winemaker’s local knowledge of history and climate to give a good indication of which microorganism is causing the disorder.

Multiple parameters give a comprehensive, multi-dimensional view, for example, ethanol is a good indication of indigenous yeast. Glycerol is also an indicator, but not as strong.

Always in the know with fermentation insights

 

Routine analysis helps to keep a close eye on the processes involved in winemaking, for example, with timely information that helps to avoid stuck fermentation. If you want to check every barrel, just go ahead. With rapid analysis to support you, you can push the boundaries of quality with powerful combinations of parameters available simultaneously.

Ahead of fermentation, you can check that the yeast has the right nutrients to grow. A test for Yeast Assimilable Nitrogen allows you to supplement nitrogen deficient must with diammonium phosphate at the start of fermentation to provide adequate nitrogen levels.

Testing also takes out the guesswork during fermentation by tracking the conversion of sugars to ethanol. The measurements also provide a valuable reference when tasting for those complex components, only discernable to the experienced palate.

For malolactic fermentation, rapid analysis tracks theconversion of malic acid to lactic acid with a simple convenient test. If you are using barrels, you can test each one at no extra cost.

 

 

 

Reliable data for perfect blending and bottling

 

 

Wine quality analysis with the WineScan SO2 (link to product) provides the option to test free and total sulphur dioxide in parallel with other parameters in just two minutes. This time-to-result compares favourably with around 15 minutes per test with other routine methods or longer for laboratory reference methods.


The multiple analysis results from a single sample will help you meet demands from customers for increasingly detailed product information. And you can complete labelling and administrative tasks precisely with accurate analysis using a small sample volume. Read more

 

Minimise use of sulphur dioxide and reduce risk
of operator error

 

Rapid sulphur-dioxide test approved for winemaking

 

Wine quality analysis with the WineScan SO2 (link to product) provides the option to test free and total sulphur dioxide in parallel with other parameters in just two minutes. This time-to-result compares favourably with around 15 minutes per test with other routine methods or longer for laboratory reference methods.


The system is also considerably more convenient, reducing manual work and associated risks of operator error. Results are delivered alongside the many other quality parameters provided by the WineScan analyser. This gives you a convenient on-screen comparison against parameters, such as pH and ethanol, of potential interest in combination with sulphur dioxide. Read more
