Sealed BP doesn't go bador need to be dated coded like Budweiser.
Itcan stay potentbeyond many,manydecades.
I don't think that you got a bad deal, they didn't promise anyonea latedate code.
I'm curious about where the research was found?
Maybe the German manufacturer doesn't even make Graf's powder using thesame formulaas they do for their own brand, or the researchthatwas found could bebiased.
