Qualities according to the manufacturer:
Created entirely by hand-selected Cabernet Sauvignon grapes, Rose Grand Prix "Black Sea Gold" of Pomorie will enchant you with its sparkling and delicate colour, reminiscent of sunrise over the sea shore. Aromas of ripe strawberries and juicy raspberries intertwine with mineral and citrus shades to end with a long glamorous finish.
Vinobg:
It is not clear exactly which rosé was awarded, especially if you look at the site of the Black Sea Gold. The prizes section there mentions the "rosé of the last vintage". Only the winery staff knows which one it is. However, the label is stuck on this bottle. So this is it.
