There's a reason the Barossa Valley is considered the heartland of Australian wine. The red clay soils, the continental climate, the old vines — some of them over a century old — all conspire to produce wines of extraordinary depth and character. Nestled right in the heart of it all, at 9 Seppeltsfield Road in Tanunda, sits Chateau Dorrien: a family-owned winery with a story as rich as the Shiraz it bottles.

A New Chapter for a Historic Cellar Door

The Dorrien name carries serious weight in the Barossa. The original winery was operated by the legendary Seppelt family — one of Australia's most storied wine dynasties — before Fernando and Jeanette Martin purchased it in 1984 and opened it officially as Chateau Dorrien on 13 January 1985.

Fernando wasn't just a businessman with a dream. He was a third-generation descendant of an Italian wine and liqueur-making family, bringing with him not only a passion for craft but recipes handed down across four generations. When he took the keys to that old cellar door, he carried with him a legacy that stretched back to the old country.

In 1990, the family expanded, purchasing the former KarraWirra Winery in the Lyndoch Valley and reopening it as Twin Valley Estate — where all production operations now take place. Today, the business is very much a family affair: Jeanette co-founded it, son Ray Martin carries on as winemaker, and the cellar door team — Jeanette, Levi, and Janine — welcome visitors with a warmth that only comes from genuine pride in what you make.
