XO Wine Co is a small boutique winery just out of Meadows in the Adelaide Hills, owned and run by Greg Clack and Kate Horstmann. The winery produces small batch wines from the Adelaide Hills and McLaren Vale, some of which are only a single barrel in size. The couples passion revolves especially around the varieties Grenache, Barbera, Chardonnay, Pinot Noir and Gamay, along with a thirst for savoury dry rose. One of the six is usually found open somewhere in the house. The passion and enjoyment of these varieties drives the couple to produce interesting, complex and enjoyable wines.
