Johann Christian Henschke purchased land around the tiny village of Keyneton in 1861 after fleeing religious persecution in Silesia. Keyneton grew to become a cultural focus for early Barossa settlers, not least of all was the Henschke Family Brass Band! The B flat euphonium, imported to Australia from Leipzig in the late nineteenth century by musical entrepreneur Carl Engel of Adelaide, was the Henschke favourite. Just like the namesake Henschke wine, a euphonium exhibits warmer and more subtle tonal qualities than it's louder modern counterparts.

Named after the early English pioneer Joseph Keynes who settled at Keyneton in 1842. Cyril Henschke established a large planting of predominantly Riesling and Shiraz at Keyneton during a time when riesling was scarce and bonuses were being paid by the large wineries. Today the Shiraz from Keyneton is reserved for Euphonium. A mostly Shiraz wine with smaller components of Merlot, Cabernet and Cabernet Franc, grown to the Eden and Barossa Valleys, vinified at the Henschke Road wineworks at Keyneton into a soft, easy to enjoy wine. Components are treated to eighteen months maturation in a combination of new and prior use French and American oak hogsheads.
