Here's a wine I would recommend http://tinyurl.com/2c7pwuk I also like CASA VINO wineries http://www.casavino.bg/?lang=en they have nice shops and a nice website in English too. A couple of years ago I really enjoyed the wines of Zagreus winery (available in shops like Hit &amp; Billa in Mladost), but I wouldn't recommend their cheap wines. They have an exceptional cuvee (shiraz+cabernet) though.

Cheers!
