Serie D No.4 (3 Sticks per Box) (Aluminum Tube)

Don Jaime Partagás is credited with pioneering systematic tobacco fermentation in Cuba — the multi-stage post-harvest process that is the direct technical reason this house's full-bodied profile has held consistent across nearly 180 years of production. That same fermentation discipline underpins every Serie D No. 4 leaving the Francisco Pérez Germán factory today.

All leaf — wrapper, binder, and filler — originates exclusively from the Vuelta Abajo zone of Pinar del Río, Cuba's westernmost province, where red clay soils and a humid Atlantic microclimate produce tobacco of unusual density and oil content. The Colorado wrapper typical of the Serie D line reflects that terroir directly: mid-brown, visibly oily, structurally tight.

Construction follows the Tripa Larga, Totalmente a Mano method — long filler assembled and wrapped entirely by a single torcedor, draw-tested on completion, and subject to spot-check rejection rates of 10–15%. No additives or casing agents are used; 100% natural Cuban tobacco throughout.

The aluminium tube (tubo) format preserves humidity without a humidor, making these three sticks travel-ready without compromise to construction.

What distinguishes the Serie D No. 4 within the Habano world is its position as the format that codified the robusto vitola as a global standard — a 52-ring-gauge, 124mm cigar that balances draw resistance, burn time, and flavour development in a way no peer has displaced since the 1930s.
