NON-DESTRUCTIVE SYSTEMS IN CAPPED BOTTLES AIMED AT QUALITY ASSURANCE

Among all the inspections performed, the measurement of total pressure, CO2 partial pressure, concentration of CO2 dissolved in wine and oxygen concentration play a very important role.

Cellar inspections during the production cycle allow to standardize chemical and physical parameters of the product and to place on the market wine with organoleptic properties, such as to ensure its proper conservation throughout the whole life cycle, thus enhancing brand and company reputation.

NON-DESTRUCTIVE SYSTEMS IN CAPPED BOTTLES AIMED AT QUALITY ASSURANCE

Among all the inspections performed, the measurement of total pressure, CO2 partial pressure, concentration of CO2 dissolved in wine and oxygen concentration play a very important role.

The great innovation proposed is to perform the measurement of these parameters through the application of laser spectroscopy in a non-destructive and non-invasive way on the 100% of production (or on a sample basis, as alternative).

How does it work?

A laser beam (properly calibrated to detect the molecule of CO2 or oxygen), passes through the headspace of the bottle and gives the measurements of total pressure, CO2 partial pressure, concentration of CO2 dissolved in wine and oxygen concentration in a quick and precise way, and with high sensitivity.

To give just a few examples, it is possible to check in a non-destructive way the concentration of CO2 in a champagne bottle during the second fermentation process (before disgorgement) in order to check on each single bottle if the yeast and the sugar added have reacted properly; in other words, this inspection determines if fermentation process has reached the end or if that specific bottle must be left in the cellar still for some time.

Presence of oxygen in the headspace. It is possible to check oxygen concentration by simply leading the laser beam through the headspace in a non-destructive and non-invasive way.

Laser spectroscopy is a technology which allows to obtain the same qualitative measures, with the big advantage of not destroying the sample and the possibility to check the 100% of production.
