In 1892, there were 92 grapegrowers in the Grampians district with some 1885 acres under vine. With the downturn in the fortunes of the wine industry earlier this century, much of this vineyard was grubbed out with some hardy survivors, such as Bests, keeping the traditions alive. A resurgence in the late 1960s and 1970s lead to the establishment of a new group of wineries, including Four Sisters. Now the Grampians region is once again recognised internationally for the absolute quality of Victorian wines.

Trevor regularly takes his seat as Judge at the National Wine Shows and is a highly regarded stalwart of Victoria's winemaking fraternity. Trevor Mast first entered the industry when he worked at Gilbeys, where he was responsible for the blending of spirits and liqueurs, and later took up a position as microbiologist for Stellenbosch Winery in South Africa.

One year his four daughters created the wine label design as a birthday surprise. Produced with the help of the eldest daughter Daliah, a graphic designer, the label depicts each one of the sisters Sophie, Anja, Daliah and Ineke. Delighted with the label mock up and his daughters' plans for a wine aptly named Four Sisters, Trevor initially crafted a small production wine from the vineyard growing behind the family home.

With the positive response from all who tried the wine and heard the original story behind it, Four Sisters is now a successful brand with a range of four classic grape varieties.
