This 4-year-old Old Jefferson Kentucky Straight Whiskey is unrelated to Jefferson’s Bourbon, that was first released in 1997. Since it says ‘Auslandische Erzeugnis’ (foreign product in German) it has to be pre-1990. After 1990 the Germans stopped stopped labeling their imported bourbon as such, due to a change in EU-regulations. This particular Old Jefferson dates back to the early 70’s. Intergena Schermbeck, the importer, also sold Uncle Sam’s Bourbon in Germany during this period.
