We had an excellent experience at 868 with a group of friends. Even took a hike up the hill to the top of the estate which sits at 868 foot elevation - hence the name of the winery. The tasting room is roomy and well-appointed, and the grounds are gorgeous, with lots of the original farm buildings incorporated into the landscaping.
Would also recommend the Grandale restaurant which is part of the winery. Had a wonderful dinner next to a huge, cozy wood-burning fireplace.
