601 Serie Maduro is Espinosa’s dark-wrapped 601 cigar line. The 20th Anniversary release marks two decades of the 601 Blue Label with Connecticut Broadleaf over Nicaraguan binder and filler. Its full-bodied profile brings espresso, dark chocolate, earth, and black pepper, with a touch of natural broadleaf sweetness. It is a useful starting point for smokers comparing richer maduro blends.
