You've been to Sakhalin?

There was a lively thread on the sci.lang Usenet newsgroup around 1990 where somebody had bought a bottle of spirit in the Soviet Far East labelled (in Cyrillic) "Chugdush". He quoted the text on the label, which was in no language anyone could identify, but there were some hilarious guesses. A lot of the words began "pt-" which I saw much later in a sample of Nivkh. Does that make sense to you?
