5.5 lb bunch of Autumn Royal seedless grape
This is probably the biggest bunch of grapes I've ever grown. It's from a potted plant of Autumn Royal. This variety has the biggest berries of any grape I grow. The berries on this bunch are smaller than normal. Brix is running about 25. Flavor on this variety comes up short. Bunch is setting on a large dinner plate.
Summer Royal has nearly as big berries and better flavor.
