Malbec, Petit Verdot and Merlot are three varieties that are particularly well suited to growing in the Margaret River winegrowing region. When blended together these varieties form a divine trinity creating a unique wine. The Malbec provides the fruit power and colour, the petit verdot the length and texture and the Merlot the structure. The fruit which made this wine came from a single vineyard in the Wilyabrup subregion of Margaret River belonging to Rick Cullen and Bettina Mangan. A wine with great drinkability and ageing potential.

James Halliday, The Weekend Australian, 18-19 June 2005
"The two biodynamic wines released from Cullen are the 2004 Sauvignon Blanc Semillon ($35; 92 points) and the 2004 Mangan ($45; 93 points); both prices cellar door. The Sauvignon Blanc Semillon has that unmistakable Margaret River combination of grass, herb and citrus aromas and flavours, with oak a mere background whisper (18 per cent was fermented in new French barriques with no cultured yeasts). Vibrant and fruity, it can be consumed with total enjoyment now or during the next 10 years. The 2004 Mangan is a highly unusual blend of 60 per cent malbec and 40 per cent petit verdot; profoundly rich, deep and fruity, it is nonetheless so super-smooth you barely notice the tannins that come behind the black cherry, blackberry, mocha and coffee aromas and flavours. Without question, the best yet under the Mangan label, and you can have it with a screwcap or cork closure."
