As promised, here's the link to the in-flight magazine of Bulgaria Air, where the article about Bulgarian wine and its industry can be found starting page 7 (7 is the sequential pdf page, the actual number on the bottom of the page is 48, because they did not include the advertisements in the online version).
Some notes about the article:
- it's alternating in Bulgarian and English; the English text is either on the entire following page, or on the bottom half of the same page if they share it.
- it is written from a Bulgarian point of view, and therefore debunks some 'myths' about the place of Bulgarian wine in the world, that will probably seem amusing to a world audience
- the name of the article, in Bulgarian, is "Bulgarian wine: rising after the fall"; I don't think the English title they chose is better.
- on sequential page 10 (bottom of page number 51, the sentence "The huge part of this export was a cheap and unpretentious product for the vast global market." should read "vast soviet market".
Finally, the subsequent article in the magazine is tangentially wine-related. It is about Melnik - the smallest town in Bulgaria, and home to the eponymous indigenous vine varietal and wine.
