I spent a bit of time searching google for the yerashk wine company and did find a couple things.

First I found plenty of local "Armenian" information to know that it exists. There are listings for it, telephone numbers, cargo shipping information, local wine festivals with them listed as participants, etc. There's no doubt the winery exists.

Second, google maps aren't very good for Armenia, The address of the winery can be easily found, but google (and myself) doesn't understand Armenian postal addresses and doesn't label any of the streets in the village of Yerashk other than a main highway.

Not surprised by my findings, just figured I'd share.
