According to Webcrafts:
Tcherga Rosé is a unique blend of the varieties Cabernet Sauvignon, Merlot and Rubin. In the same way as the traditional Bulgarian rug gathers together the colours of Bulgaria, this wine combines the tastes and aromas of three best wine grape varieties of the Thracian Lowland. The result is a wine with a character that bears the spirit of South Bulgaria.
The wine has an attractive wild cherry colour. The aroma is delicate, with nuances of wild strawberries, raspberries and blueberries. The taste is fresh, velvety, full and soft, and the palate leaves a lasting memory of red berries. All these qualities make this rosé a delicate, palatable and most attractive wine.
