The Four Sisters are actually the four daughters of the late Trevor Mast, a legendary Australian winemaker who established the Mount Langi Ghiran winery. The classy label was designed by the eldest daughter, Dahlia, a graphic artist. Trevor's idea was to create a graceful wine that his daughters would enjoy drinking with their friends.
Four Sisters Cab has all the positive qualities you expect from a high quality Cabernet but at a fraction of the price. Black currant fruit and understated oak. Significant depth and complexity. Four Sisters sells for about $12 a bottle (when you can find it). I found it ($5.75 a glass) on the wine list of Phoenicia Taverna, an excellent Lebanese restaurant in Mason, Ohio.
