5 Star Winery - Halliday Wine Companion
"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 just the third owners of the property
Today more than 70% of the red wine produced at Kaesler are made from vines over 50 years of age, including the Old Bastard Vineyard planted in 1893 and the Alte Reben Vineyard, planted in 1899." - Tourism Barossa
