Via the Australian Manly Daily:

While Windrim is only one of a handful of practicing biodynamic viticulturists in Australia the list also includes iconic wineries such as Cullen, Jasper Hill and Castagna wine aficionados may be more familiar with the success of Burgundy’s Domaine de la Romane-Conti which is renowned as “the scarcest, most expensive and frequently the best wine in the world”, produced entirely biodynamically. Depending on the vintage, prices can range from $500 to $5000 a bottle. As you can see, the biodynamic phenomenon has some big-time devotees.
