August is hurry up and wait time in the wineries and vineyards. The grapes are almost to their full size but haven’t turned colour yet. Red, pink and white grapes are all still green. Until the sugars start to push them into their proper ripe colouring, they will stay green. Each grape variety changes its colour at different times. This is called “veraison” and is an important indicator of the progress of the season. Starting mid-late August, veraison will give growers and indication as to when to expect the harvest.
