The turbidity of this standard solution is. This standard suspension will keep for approximately 4 weeks at room temperature in the dark. With recently prepared distilled water, a turbidity of 1 ntu will be obtained. This solution remains stable for one week only. Ntu turbidity in wine the turbidity of red wine during its aging in oak casks has an influence on the accumulation of volatile compounds and, thereby, on the wine. S aroma, but not on the accumulation of biogenic amines. This is the conclusion of nerea jiménez moreno in her thesis defended at the public university of navarre. Ntu vs wine filterability index. What does it mean for you. Paul bowyer, turbidity.
My wine had low turbidity but still needed extensive. But still needed extensive filtering. Wine had a turbidity of less than one ntu. For the winemaker we offer a precision benchtop turbidity meter that can measure turbidity from 0. The turbidity measurements. Is a method to quantify the visual clarity. Yeast, bacteria, amorphous material and crystals are some of the wine components which cause turbidity in wine. Usually a wine with a ntu reading 1, 0 prior to bottling is seen as clear enough. If it is however 1, 0 another filtration prior to bottling is recommended. Reading of 1, 0 is however not necessarily a guarantee that the filter medium will not be blocked.
