It was November 2015 and an unusually warm afternoon at Marqués de Riscal, one of the grandest wine estates in northern Spain. Andrew Caillard, a Sydney-based Master of Wine, decided to take a break from three days of tasting and go for a walk.

When Caillard is not working as fine-wine principal for Dan Murphy’s and Langton’s, he is a painter of bold, colourful landscapes. That afternoon, as he looked at the extraordinary shimmering titanium roof-ribbons of the Frank Gehry-designed Riscal winery, he opened his sketchbook.
