I haven't been for a couple years, but I thought it was worth the trip with some caveats.
It's a cool building and a scenic site.
Their wines are on par with what you will find in the area. Not the greatest (I will admit to wine snobbery) and more expensive than what you might expect.
Their beer was pretty good. I think they had a wheat beer on tap when I was there, and IIRC the price of a pint wasn't too bad (+/- $5). I didn't buy any bottled beer.
They had a grill going too and we got lunch for the kids and ate outside.
All in all it was very nice. But it was more a nice experience than outstanding products. I would definitely go back.
We also have enjoyed Domaine Berrien, which is close by. They have a nice tasting room and you can get a bottle and some cheese and sit out on the deck. But they do not brew beer.
