Cold stability is the wine’s ability to resist the precipitation of tartrates causing crystallisation. Cold stability tests are an essential part of winemaking as consumers demand brilliant clarity. Conductivity is an objective measurement of the potassium ion concentration in wine. Precipitation of tartrate decreases the conductivity over time. Results indicate the potential stability of the wine.
Tsat gives quick results on tank whites & light rosé.
ISTC50 determines whether the wine is stable after treatment
DIT% determines if the wine is stable prior to stabilisation treatment and, if it is unstable, what level of treatment is required.
