With a rich history that dates back to 1692, Hartenberg has passed through the legendary families of Finlayson and Gilbey until the late Ken Mackenzie purchased the estate in 1987. Situated on the slopes of the Bottelary Hills, the terroir is renowned for fine quality and ageability. CWG member Carl Schultz has presided as the head winemaker for over 25 years and has produced world class, powerful reds. Previously only released through the CWG, the Gravel Hill Shiraz holds the record for the longest Guild 'accreditation'. The 2005 was only the 2nd vintage to be released through the farm.
