Monte 3 from a 5 pack, no date provided. Absolutely awful, didn't want to burn and when it did, it was like a burning trash bag. Even worse is that the first couple of puffs were brilliant, pure cocoa powder.
A couple of nights ago I had a Jose L Piedra Cazador from a 5 pack I got at the Salzburg Hauptbahnhof in 2018 that was pretty rough, not sure I got halfway through before tossing it in the grill.
