TARTARIC STABILITY ANALYSER
Tartaric stabilization is linked to the phenomena of precipitation, caused by potassium and tartaric acid present in wine. These two substances are already present in grapes, but without chemically coming into contact; on the other hand, when the grapes are pressed, the two substances mix and can create problems of precipitation of potassium bitartrate.
This precipitation is a slow process that can take place in the cellar after the fermentation of the must or directly in the bottle, after the bottling of the wine, once the wine reaches the shelves of the wine shops.
This phenomenon does not cause any organoleptic damage in the wine but certainly, from a visual point of view, the product is not considered of quality and is not accepted by a consumer and an increasingly demanding market.
TARTARIC STABILITY ANALYSER is an automated system for measuring tartaric stability in wine.
It is an ultra-compact analyser and requires only electricity for correct operation and cooling of the sample.
The system is fast, easy to use and provides a repeatable stability measurement along with the ability to store records, even connecting in remote with specific app.
TARTARIC STABILITY ANALYSER operating principle is to favor the precipitation of potassium tartrate by adding excess THK. The measurement of stability then derives from the determination of the electrical conductivity, uS, of the wine under different temperature conditions
