It's nice that there is a winery nearby.. I'd say its good in that aspect but nothing to write home about when compared to popular, well known wineries in other places.
I like that you can get 3 complimentary tastings and reservations aren't needed. The last time I went (Saturday evening), the lady serving us wasn't the nicest, but she warmed up to us.
They have an expansive covered picnic area where you can bring your own food and do stuff, which is cool for events.
