So I just called the source of my clear question- it actually makes a blush wine. He said you have to crush the grapes and then press them. The juice will be a nice color.
Onto the sugars. He also said that concord grapes will not be ready to pick until late september around here (Lancaster, PA). He thought that the grapes should get to 15 brix. He also noted that a lot of people pick concords way too early and that is why they don't have the sweet flavor that they can have. He acted like this year's concord crop from PA and New York were going to be very late and barely hit 15 brix. He acted like it could get up to 16-17 on the brix with a good year. We have had a very cool and damp summer. It was nice on the electric bill but not so nice for the garden. We need those hot days to burn off moisture. He also said that this year's weather was terrible for grapes so you may pay a little more for your wine or grapes from New York.
