Latvian link
Beer-Stained Letter gets a mention (more like a link) from a Latvian beer blog.
Credit lies in video, the stone beer piece featuring homebrewer Maris Kukainis of Cherry Hill. Maris is of Latvian descent and did a stone beer with a ancestral slant.
The blog Labs Alus, which means "Good beer" in Latvian (or so says the Google translator site), embedded the video with a link to BSL under a heading Latviešu akmeņu alus no ASV, which translates as Latvian stone beer from US.
Kinda cool.
