"This was our first trip to Markham and I'm looking forward to going back. As a member of their wine club we received a nice tour of the property and and wine making process. We then had an opportunity to sample many of their wines including the Altruist and Philanthropist! Kevin was our Wine Educator. He was very knowledgeable, interesting and had a good sense humor. We visited a number of wineries during our trip. Markham was the largest producer but they made you feel like all their guests were VIPS. They also make the only Merlot I actually enjoy drinking!"

"We attended this winery as one of several during our trip. It combines modern and old style very well. I liked the photo gallery and Rolling Stone pictures - something different. The tour was up on a catwalk, so you could really see what was going on. The wines were well done too. All in all a good experience." - Phil from Illinois


"Beautiful first impression walking inside the tasting area. A koi pond and beautiful original architecture. Inside there's a rock and roll museum of some of the classic greats. The staff was incredibly nice and welcoming. There wasn't a wine I didn't like. The staff taught us a lot about the wines and the area and really made our experience a memorable one." - Jennifer from New York
