In taste, it's tender, fine-grained (NO air bubbles), and dense with a dark brown chewy (really, really, chewy) crust. Like other breads made without wheat flour, it has a low rise (low gluten), is about the color of Idaho potato skins inside, and has just a bit of a tang. Not like a strong sourdough. It's not at all like the dark Bavarian rye as it's both lighter in color and very tender in texture. It's not like a "traditional" rye you'd buy for a sandwich as it's denser, shorter, and the tang is somehow different.
This man's
post sort of explains the history of how he started making it. Looks like some starter is involved.
This guy must really love food; this
series of posts are very interesting.
The replies to this
recipe make it sound like the process must be similar to a Lithuanian Black bread, but that would be different.

history....
I did find this
recipe- from a recipe written in Lithuanian - but I have no clue what it makes! It sounds good, but I don't remember kefir in Baltic Bakery's list of ingredients....then again, it's been so long since I've had it, well, it might be.
Hmmm, now this one - that I didn't find last time I looked, seems promising. The starter is actually a bit of leftover dough. But, I am guessing that Baltic may have used some all purpose flour, simply because it is so light in interior color. If it were all rye, it would be a bit darker, I'd think.
