The spiritual father is master blender Francisco Fernández, nicknamed “Don Pancho“.
He has more than 50 years of experience in rum production.
He began his career in Cuba in the 1960s, where as director of the beverage industry he introduced improvements that are now used as standard.
Since the 1990s, Don Pancho has lived in Panama, where he crafts the world’s finest rums.
The carbohydrates in molasses are converted into alcohol and carbon dioxide by yeast during the fermentation process.
Fermentation itself is an exothermic process (releases heat), so the fermentation tanks must be cooled with water. A constant fermentation temperature of 32 °C and a pH value between 4.0–4.5 are maintained.
Heffron rum is produced using continuous distillation, sometimes also called column distillation. This is the most widespread method for rum production. The Panamanian distillery has a column of enormous dimensions. It contains several dozen distillation plates, making the distillation multi-stage — which is why young Heffron rum is very pure, yet retains a wealth of flavour carriers from sugar cane.
Every drop ages in the barrel for this entire period. During aging, rums of different ages are never blended — unlike some other rums.
Heffron Heritage 5YO ages in select barrels that previously held bourbon. Here too the aging period is 5 years. These barrels have different aging properties and lend the resulting rum an entirely different flavour character.
The unique flavour profile of Heffron 10YO comes from the meticulous work of experienced blendmasters. The masterfully chosen blend of ten-year-old rums, aged in sherry, bourbon and cognac barrels, gives the final product a rich palette of flavours and aromas to be savoured in every glass of Heffron 10YO.
During aging, compounds are extracted from the barrels — including tannins, calcium salts and colourants, as well as quercetin — all of which give the final spirit its specific flavour and aromatic characteristics. Every barrel is different. Its properties are influenced by whether it is newly made or whether it previously held another fine distillate. We are proud that some of the world’s most experienced blendmasters contribute to the production of Heffron rum, drawing the very best from every barrel.
Our work does not end with distillation — it is in this final stage that the rum acquires its ultimate character.
The environment of the Prostějov cellar, with its unique microclimatic conditions quite different from tropical Panama, helps to gently fine-tune the flavour profile. At this stage, harmonisation takes place, during which the rum reaches its final strength of 38%, or 40% — carefully chosen to perfectly develop its aromatic complexity, depth and velvety smoothness.
The result is a spirit of extraordinary elegance, combining craft precision, terroir and time.
Every drop bears the hallmark of expert care and the environment that shaped its character — unhurried, with respect for both tradition and modern methods.
