The 601 series is Pepin Garcia tobacco under the EO Brands label, and Blue is the fullest of the colors. Box-pressed in every size, with a maduro wrapper over Nicaraguan long-filler.
Heavy pepper on the light, then espresso, dark chocolate and a leather core. The box press tightens the draw considerably, which is part of why this blend hits as hard as it does.
