Partagás Serie D No.4 In Depth: The 50 Ring Gauge Robusto Legend of the World's Best-Selling Cuban Cigar and Its 1975 Rebirth

In the global cigar market, one cigar is repeatedly cited as "the best-selling Cuban cigar in the world" -- it is not Cohiba, not Montecristo, but Partagás Serie D No.4.

124mm, 50 ring gauge. A Robusto. Each cigar takes about 55 to 70 minutes to finish. Its success is not due to rarity, nor to marketing, but because it achieves "just right" in every important aspect: the flavor is just rich enough, the strength is just on point, and the format fits the pace of modern life perfectly.

This is the story of the D4, and also the story of how a cigar went through discontinuation, silence, and rebirth, ultimately becoming number one in the world.

1. The History of Partagás and the Legend of Don Jaime

Partagás is one of the most important cigar brands in Cuban history. It was founded in 1845 by Spanish immigrant Jaime Partagás Ravelo at No. 520 Industria in Havana as the "Real Fábrica de Tabacos Partagás". This magnificent factory building still stands on its original site today and has become a historical landmark of Havana. It is now known by the factory code "Francisco Pérez Germán" (abbreviated as FPG).

Don Jaime made three core contributions to the Cuban tobacco industry: first, he was one of the earliest tobacco merchants to systematically acquire tobacco from plantations in Vuelta Abajo, ensuring vertical integration of raw material quality; second, he introduced the "lector system" in the factory -- books were read aloud to cigar rollers inside the factory, improving workers' literacy and workplace cohesion, and this system later became a hallmark of Cuban tobacco factory culture; third, he brought the Partagás brand into the high-end British market, establishing a lasting image of the British gentleman. In 1868, Don Jaime was murdered in his own tobacco fields. Over the following nearly eighty years, the factory changed hands several times, and after the Cuban Revolution it was ultimately placed under the management of Cubatabaco, becoming one of the core brands under Habanos S.A.

2. The Birth, Disappearance, and 1975 Rebirth of Serie D

In the 1930s, Partagás launched a series of cigars for the British market classified by letters -- Serie A, B, C, and D, with several models in each series arranged by number. Serie D No.4, with its original specifications of 50 ring gauge x 123mm, was designed for British gentlemen who favored thick, powerful flavors. It was one of the few Cuban cigars at the time bold enough to use such a large ring gauge.

However, by the 1960s, after the Cuban Revolution and the restructuring of the market, many niche series were gradually discontinued, and Serie D No.4 disappeared from the market for a time. After a full fifteen years of silence, in 1975 the predecessor organization of Habanos decided to relaunch this Robusto. The reintroduced version was adjusted in length by one millimeter, becoming the current 50 x 124mm specification, and was repositioned under the then still-emerging "Robusto" format -- a decision that profoundly influenced format preferences throughout the cigar world.

The Robusto format (around 50 ring gauge, a cigar that can be completed within two hours) rapidly became popular worldwide after 1975, and Partagás D4 was one of its most important drivers. Many industry figures believe that the success of the D4 directly prompted other brands to launch their own Robusto series in large numbers, and also made "a 50 ring gauge cigar that can be completed in about an hour" the standard everyday choice for the modern gentleman.

3. The FPG Factory: From Industria 520 to the 2012 Relocation

The core factory of the Partagás brand had long been the magnificent nineteenth-century building at Industria 520 in Havana. This factory was not only a production site, but also an iconic destination for Havana cigar tourism -- large numbers of visitors came every day to the exhibition area to admire the skilled rolling techniques of the torcedores, making it a must-visit stop on many cigar enthusiasts' pilgrimages to Havana.

However, on January 2, 2012, Habanos S.A. made a major decision: to move the main production lines to a new factory in the suburbs of Havana, about three kilometers from the old factory. The new factory was named after Cuban revolutionary hero Francisco Pérez Germán, with the factory code remaining "FPG". The original Industria 520 building retained some exhibition functions, but large-scale production of the Partagás brand moved fully to the new factory.

The artisans of the FPG factory are known for handling strong, oil-rich leaves. The leaf blend of the Partagás brand uses a large proportion of Ligero leaves (the leaves at the top of the tobacco plant, with the longest sun exposure and the richest oils), requiring highly skilled torcedores to achieve an even burn without tunneling, uneven burning, or overheating. As the factory's most representative flagship item, Serie D No.4 represents the benchmark and quality commitment of FPG craftsmanship.

4. Appreciation Notes: The Cuban Equation of Coffee, Leather, and Cinnamon

The flavor profile of Partagás D4 is the most representative epitome of the Partagás brand, and for many cigar connoisseurs it is the first stop into the world of medium-full Cuban cigars.

From lighting to the first 1/3: Direct and unapologetic. The first puff brings a rich coffee aroma -- dark-roasted, with a hint of bittersweetness, a direct expression of the Ligero leaves. The cedar base note is clear, with occasional faint cocoa tones drifting through. In high-quality examples, the burn line in this section is straight and even, the draw resistance is moderate, and the smoke volume is abundant, giving a vivid first impression that "this cigar has something to say".

Middle 1/3: This is the most charming moment of the D4, and the key to its surpassing most competitors. Aromas of leather and walnut begin to layer in, while the spicy note of cinnamon appears faintly -- not an uncomfortable sharpness, but a warm sweet-spice sensation, like the memory of a freshly baked cinnamon roll. Sweetness on the finish begins to emerge, and the aftertaste in the mouth starts to lengthen. The overall strength at this point is about "medium-full", just right for connoisseurs accustomed to Cuban cigars, while newer appreciators may need to slow the pace slightly and let the cigar cool a little.

Final 1/3: A caramel sweetness covers the bitterness of the earlier section, and the overall flavor becomes rounder. The final few puffs are the essence of the entire cigar -- the later stage of the D4 is often richer than many cigars in the same price range. It does not fade, nor does it turn bitter, and this is a core indicator of its consistency. The tight, fine gray ash at the end is also a visual confirmation of leaf grade and rolling craftsmanship.

Overall, the D4's "medium-full" positioning makes it a perfect "all-round" choice: not overly sharp for beginners, deep enough for seasoned aficionados, and just right in pace for everyday appreciation at a gentlemen's club. Paired with a cup of black coffee or vintage Armagnac, it is one of the most common golden combinations at W Cigar Bar gentlemen's club.

5. The Serie D Family: The World Beyond D4

Serie D is not limited to No.4. The complete Serie D family also includes:

• Serie D No.1: 47 x 190mm (Laguito No.1 format), longer and requiring more time, the long-distance runner of the D family, suitable for extended weekend afternoon appreciation
• Serie D No.2: 52 x 152mm (Piramide torpedo), a special tapered format that is narrow at the front and wider at the back, with draw resistance gradually increasing and an extremely focused flavor presentation
• Serie D No.3: Elegantes format, discontinued and now a collectible item
• Serie D No.5: 50 x 102mm (mini Robusto), a shortened version of the D4 that can be completed in about 30 minutes, suitable for occasions with limited time

The special position of No.4 within the entire D series lies in its complete expression of the core characteristics of Partagás, without the long time commitment of No.1 and without the tapered draw challenge of No.2 -- it is the "most Partagás" cigar in the D series, the spiritual center of the entire line.

6. Selection Guide and Current Market Situation

Serie D No.4 is mainly packaged in 25-count wooden boxes (SBN), and there is also a Tubos aluminum tube version available. The Tubos version is more practical in situations with less ideal humidity control (travel, going out), while the wooden box version usually shows a more natural and fuller flavor profile.

Selection confirmation items:

• The box surface has the FPG factory code (Francisco Pérez Germán)
• The Habanos S.A. holographic anti-counterfeit label is intact and located at the lower right corner of the box lid
• Sourced from the four major regular channels, with receipts retained for reference

Aging potential: New D4 already performs well, but after 3 to 5 years of aging, the sweet-spicy cinnamon sensation becomes rounder, the bitterness of the coffee note retreats into the background, and the overall complexity improves significantly. It is well worth setting aside a few boxes for long-term aging, and it is one of the core items in a gentlemen's club cellar.

Conclusion: Why Is D4 the "World's Best-Selling"?

Because it does not compromise in any aspect.

It does not try to be the lightest cigar, nor does it try to be the strongest -- it is simply "the one cigar a gentleman needs in daily life". The 50 ring gauge provides sufficient complexity, the 124mm length ensures a complete time experience, and the quality control of the FPG factory makes every batch trustworthy.

The decision to relaunch the D4 in 1975 allowed an almost forgotten British gentleman's cigar to become, fifty years later, one of the most recognizable synonyms for Cuban cigars in the world. This was not accidental, but the long-term reward of doing everything right.

The sound of the wooden lid opening on every box of Serie D No.4 is a reassuring signal: some things only get better with time.
