Effect of harvest date on composition and geometry of grape berries
Original language description
During wine production, the composition of grapes at the time of picking is an important parameter. To determine the harvest day may be considered the most crucial decision in winemaking. While grapes ripen, some complex physicochemical and biochemical processes occur, such as the continuous rising of sugar concentrations and lowering of acid levels, respectively. Chemical composition of seven grapevine cultivars harvested weekly during six consecutive weeks in the South Moravia region (Czech Republic) was evaluated. In addition parameters like size, shape and mass of grape berries were also studied. The geometry of the berry was described using its digital image. This procedure enables to describe the contour curve and to evaluate volume, surface and radii of the curvature. The mass of the berry, surface and volume increased with the total sugar content in all cultivars except for 'Pinot Gris' and 'blue Frankish' cultivars. The radii of the curvature were increased in all cultivars tested.
