A question on grapes?

[KodiCarnage]

Ok, I am at work for the next 12 hours, and decided to research a lil on brewing as I am going to work on it soon. I'm kinda quirky and would like for my guys to be able to drink fruit juice instead of water and milk all the time (although milk does their body good) ... my question is will grapes work in the combine for fruit juice? Like I said, I'm at work and can't just hop on quick and find out, and the question is really eating at me. Thanks in advance.

You need foraged fruits to make the fruit juices, the vendor sold grapes are for other brewed drinks.
