The Kaesler vineyards were owned and run by the Kaesler family from 1893 to 1986. 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.

Now having access to premium old vine material, Reid set out to produce bold estate wines representative of the Barossa Valley. The intensity of the old vine Shiraz inspired Reid to produce a special premium batch, the “Old Bastard.” Classified as “Outstanding” by Langtons with its rich and intense fruit style, the Old Bastard Shiraz paved the way for Kaesler. A string of highly celebrated wines followed suit, the generous Stonehorse range and premium Old Vine Shiraz, “The Bogan” and Alte Reben wines to name a few.

A 5 star James Halliday rated winery, Reid and winemaker Stephen Dew, with their distinct style and modest winemaking techniques, consistently produce wines rated over 90 points by industry peers and publications.

Adding to our growing family, Reid and his partners acquired vineyards in the prominent wine regions of the Clare Valley and McLaren Vale, establishing the Clare Wine Co. and Nashwauk brands. Applying the same winemaking techniques and philosophies as their Barossa Valley wines, they created a signature style that emanates across the all their regional brands.
