My wife has Concord grapes and until now we've used a hand crank food mill to squeeze the juice out.  She has more vines every year and it's way too much work to do it with that little food mill.  What's out there that would work better.   She has a Champion juicer but that won't work with the seeds in Concord grapes.

The old man that does the food mill is getting worn out, so need to find something better.   Thanks.
