Molasses flavor in beer

[squiggy]

I was recently in Eastern Europe (Czech Republic and Hungary). I had 2 very tasty black lager biers; Eggenberg and Dreher. Both beers had very nice molasses aroma and flavor. I believe these are all malt biers. Where does this molasses flavor come from? Dark caramel malt like special “B”???

In my experience those flavors usually show up when darker crystal malts are used however I usually only get the molasses type notes when its an older bottle.
