The Harvest Wine Trail is "not so ordinary," as most years you'll find the grape harvest underway. You may be able to stomp a few grapes, taste a newly pressed juice or even help with a harvest along the way!
There is exceptional value in this Trail as your $30 per person will guarantee a taste or tasting at each of the 22...yes, 22 wineries on the Trail.
