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. Kaesler owns just over 37 hectares (92 acres) of vineyards in the Barossa Valley, the majority of it is old vine material planted in 1893, 1899, 1930 and in the 1960’s.

The Barossa Valley is world famous for concentrated styles of Shiraz. Bogan Shiraz is well known to be a quintessential, full bodied style of Shiraz. The two Shiraz vineyards from which this wine is sourced complement each other well – The Marananga block provides intense, old vine produce with particular “blue fruit” offerings. The Nuriootpa block provides more “black fruits.” Winner of Australia’s Best Shiraz, Great Australian Shiraz Challenge.

"The wonderfully named The Bogan shiraz from Kaesler hails from 2 vineyards planted in 1899 (Marananga) and 1965 (Nuriootpa). As the name suggests, it's a full-bodied, sinewy Barossa shiraz of substantial clout. Dark plum and blackberry fruits, dredged deep with spice, licorice and dark chocolate. There's a sense of latent power and throaty, grainy tannins chug under the bonnet. Substantial" 93 Points.  - Dave Brookes (Halliday Wine Companion)
