The Kaesler family were pioneers who settled in the Barossa Valley in the 1840s. In 1891 they bought a parcel of land and in 1893 planted their first vines. In 1999, winemaker Reid Bosward seized the opportunity to become the head of the new Kaesler family when he and his partners bought Kaesler, becoming the third owners of this property. At this time, the Kaesler vineyards consisted of over 70% red wine vines, all 40 years of age or more.
