We’ve read from our Five Vine grower participants this summer that Cabernet Sauvignon is one of the later varieties to ripen. Kerry Shiels of DuBrul Vineyard announced this morning that the Cabernet vine at DuBrul Vineyard is in veraison.
During the month of August the grapes begin to change color known as veraison. During this time the vineyard workers prune the canopy and excess grape clusters. At this stage, the grapes still taste sour and are immature.
