"Aecht," I have researched is an antiquated German/Bavarian word for "genuine" or "real". Its almost the equivalent of saying "Ye Olde" in English. "Altbayerischer" means "Old Bavarian". So you get the general idea, its the real old fashioned Bavarian schmalzler.
I find it to be sweeter and less smokey than the Brasil types from Bernard. It has deep rich notes of maple syrup and dried figs and dates as others have mentioned. It is also got a higher degree of grit to its grind, meaning it will dissolve in your nose into a runny mess. I try to avoid blowing as long as possible, so I often have this driping on my face while enjoying it. Not for heavy use in public places! Excellent with a hot cup of strong tea. Nice nicotine buzz. My only complaint is the small (10g) sizes its sold in. They work well enough, but empty too quickly.
