Veraison and tissue sampling

Wednesday, August 25, 2021

In the last couple of weeks, the grape clusters have been changing slowly from dark green color to more yellowish or reddish, to be turning their final color. This process is known as veraison, the grapes start the synthesis of color, plus the accumulation of sugar and degradation of acids. Also, once the grapes reach veraison, it’s a good time for tissue sampling for nutritional purposes.
