It's Cascadian Farms organic. I diluted it with some water. Y'all can call me Joe if you want to, which is my real name.
I think it tested at around 20 and quite fuzzy.
Do you mean fresh organic or conventional grapes or both? I have a feeling you are referring to home grown grapes. They say grapes can be high in pesticides, so if they test high vvf Brix, does this mean to eat them, pesticides and all? We used to have nice Concord grapes in backyard vines.
