There are relatively few Croatian wines imported into the U.S., according to Wine-Searcher. I suspect this is due to the garagiste nature of the producers as well as the difficulty we all have with the seemingly odd language - to our way of thinking, there is a dire shortage of vowels in the Croatian alphabet!

This wine is a case in point. Made from a local grape called Grk, it is pronounced much like the word 'Greek', but with a less drawn out long 'e' sound. It accounts for 13% of Croatia's planted vines and isn't found outside Croatia.
But no matter how you spell it or pronounce it, I recommend seeking out a bottle or two. As to its expected price - this one was about $53 on the Ikra restaurant's wine list (Split, Croatia), so I'd guess it sellls for about $20 in local wine shops. What the up-charge will be for importing to the U.S. is the big unknown.
Fun Fact: Grk is unlike 99% of the world's grape varietals. In the springtime, its clusters of tiny buds contain only female functional parts. Most grape vines produce buds with both a pistil AND a stamen, and are self-fertilizing. Before Grk vines can produce fruit, an outside male influence is required, along with plentiful birds, bees, butterflies and breezes!
The result? A delicious wine that rewards the taster with a richness balanced by a zesty, zippy-citrus finish. It compliments a wide variety of dishes, from the rich, briny sweetness of lobster, shrimp or crab to the austere challenge of oysters with a squeeze of lemon. Look for a bottle of Grk wine at your favorite upscale wine merchant, then break out the seafood!

Cheers!
Dave, hard at work tasting wines in Croatia!
