About Us

Meet John & Jan – Your Ajax Winemaking Team!



John Marks and Jan Schmidt assumed ownership of Sisters’ Winery in September of 2004. After lengthy careers with the Bank of Montreal, an opportunity arose in the wine business and they have not looked back.

Being an avid home-winemaker with grape vines growing in his yards in Ajax and Thornhill, owner John brings an unparalleled expertise to the business, including decades of experience in making wine from homegrown grapes to managing the production of wine kits with juice from all four corners of the globe!

When it comes to the business side of the winery, Jan has it covered. She is continually developing a better knowledge of the intricacies of the wine industry and enjoys helping to create the perfect wine experience for any special occasion such as:
  • Weddings
  • Birthdays
  • Christmas Gifts
  • And More!

You can even add a personalized touch with a custom label!
