2-minute read To achieve the desired quality of wine, grapes need to be harvested at a specific maturity level. A key determinant of maturity is grape sugar levels. In simple terms, sugar levels at the time of harvest determine the alcohol content of the wine produced, but it goes beyond that to affect the characteristics and temperament of the wine. Predicting when grapes reach the desired ...
The refractometer is usually the preferred option as it is easy to use and can be taken into the field. pH and TA content: pH of sampled grape juice is measured in the laboratory using a pH meter. As acid content decreases during maturation, pH increases, and grapes harvested at below or above optimal pH result in wine with undesirable flavour, ...
To study the pollution status, vegetables (tomato, pepper, bean, purslane, cowpea), fruits (apple, plum, pomegranate, walnut, watermelon, peach, cherry, grape), and leaf samples were taken from 12 different places being irrigated from the Gediz River.
