I'll say the smoked beers must be an acquired taste haha.. That being said I prefer the doppel to the lent - the oak smoke seems less overpowering and seems to work better with the beer to me.
This thread made me buy a couple of their beers yesterday, I think I got the double/doppel bock and the lent beer. Was wandering the German imports section and noticed these. No idea how old they are, but looking forward to trying them tonight or tomorrow.
