THE FEATURES OF MURFATLAR ‘PINOT GRIS’ MUST AND WINE OBTAINED AT ADVANCED OVER-RIPENESS

Under the conditions existing at Murfatlar vineyard, the Romanian ‘Pinot gris’ variety may be harvested at advanced over-ripeness.
In this case can be obtained naturally sweet wines of a special quality.
The research is referring to establish ‘Pinot gris’ grapes composition and to establish ‘Pinot gris’ musts composition from berries sampled at different maturity stages: at complete maturity, from berries at over-ripeness, from berries at advanced over-ripeness, and from mixed berries over-ripeness and at advanced over-ripeness (global vinification).
The must resulted from the berries harvested at advanced over-ripeness show important increases in sugar content, total and volatile acidity and decreases in the flavour, comparatively with the must resulting from berries harvested at standard over-ripeness.
The wines obtained from lately harvested grapes are characterized by the high values of the following: alcohol forming power, reduced extract, ash content, glycerol, total and volatile acidity as well as by a high concentration of the evaluated components.
The advanced over-ripeness leads to obtaining naturally sweet wines, but in the same time at a considerable lost harvest.
