Geographic Indications (GIs) : European Union (EU) Geographic Indications
The European Union’s system of Geographical Indications protects regional spirits by legally defining where they must be produced and how they must be made. Unlike the highly prescriptive Appellation d’Origine Contrôlée used in Martinique, the EU GI framework is broader and more flexible.
It safeguards origin, production heritage and minimum quality standards while allowing producers greater technical freedom. Although several of these regions produce exclusively Agricultural rum, the official EU GI titles do not include the word “Agricole.”
The term describes a production method, not the protected name.
Four rum producing regions fall under this system:
Guadeloupe
Réunion
French Guiana
Madeira
Each GI reflects the agricultural, industrial and cultural realities of its territory. Some embrace dual track rum economies; others enforce strict agricultural purity. Together, they form the backbone of Europe’s protected rum landscape.
Rhum de la Guadeloupe GI
Rhum de la Guadeloupe received its EU GI in 2015. It protects a region with a dual heritage. Fresh sugar cane juice distillation and traditional molasses based rum.
Unlike the rigid Martinique AOC, the Guadeloupe GI is deliberately flexible, reflecting the agricultural and industrial diversity of Basse Terre, Grande Terre and Marie Galante.
The Rules of the GI
Geographic Scope.
All stages of production must occur within Guadeloupe.
Raw Materials
Two categories are recognised: Rhum Agricole from fresh cane juice Rhum de Sucrerie from molasses or cane syrup
Sugarcane Cultivation
Genetically modified cane is banned. New varieties require three years of monitored cultivation before approval. No maximum yield per hectare is imposed.
Fermentation
Fermentation must be discontinuous. Continuous systems are prohibited.
Distillation
Maximum distillation strength is 90 percent alcohol by volume at twenty degrees Celsius. Minimum volatile substances are 225 grams per hectolitre of pure alcohol.
Approved stills include Charentais pot stills, batch stills and multi column continuous stills.
Water
Reduction water must not alter the rum’s core flavour.
Maturation
White rum must rest for a minimum of three weeks. Wood aged rum must mature for at least twelve months. Old rum must age for a minimum of three years in oak casks of no more than six hundred and fifty litres and must contain at least three hundred and twenty five grams of volatile substances per hectolitre of pure alcohol.
Minimum bottling strength is forty percent alcohol by volume.
Additives
No lime in fresh juice.
No sugar added before or during fermentation.
What the GI Protects
It protects Guadeloupe’s dual rum heritage, ensuring both agricole and molasses traditions remain legally tied to the region. Minimum congener levels guarantee flavour concentration and prevent neutral, characterless distillates.
What the GI Does Not Protect
It does not enforce a single style. Producers may choose raw materials, still types and fermentation methods, resulting in a wide stylistic range from heavy pot still molasses rum to light column still agricole.
Summary / Key Takeaways
The Guadeloupe GI is pragmatic. It protects origin and authenticity without imposing rigid uniformity. It demonstrates that a region can maintain identity while allowing technical freedom.
Rhum de la Réunion GI
Réunion’s GI reflects a dual rum economy shaped by both industrial sugar production and fresh cane juice distillation. It is flexible, pluralistic and designed to accommodate everything from large scale column stills to traditional batch operations.
The Rules of the GI
Geographic Scope
All production stages must occur within Réunion.
Raw Materials
Two categories are recognised: Rhum Agricole from fresh cane juice Traditional rum from molasses or cane syrup
Sugarcane
Cane must be locally grown. New varieties require monitored approval. No maximum yield per hectare.
Fermentation
Both continuous and discontinuous fermentation are permitted.
Distillation
Maximum distillation strength is 90 percent alcohol by volume at twenty degrees Celsius. Minimum volatile substances are 225 grams per hectolitre of pure alcohol. Stills may be pot stills or multi column continuous stills.
Water
Water must not alter flavour.
Maturation
White rum must rest in vats.
Wood aged rum must mature for at least twelve months.
Old rum must age for a minimum of three years and contain at least three hundred and twenty five grams of volatile substances per hectolitre of pure alcohol.
Minimum bottling strength is forty percent alcohol by volume.
Additives
No artificial flavourings. No sugar added before or during fermentation. Traditional rum must remain unsweetened. Caramel is permitted only for colour consistency.
What the GI Protects
It protects Réunion’s dual heritage and ensures minimum aromatic intensity through congener requirements.
What the GI Does Not Protect
It does not enforce a single style. Réunion rum ranges from heavy pot still molasses distillates to light column still agricoles.
Summary / Key Takeaways
The Réunion GI is flexible but robust. It protects origin while allowing producers to choose their preferred technical pathways.
Rhum de la Guyane GI
French Guiana is the only mainland territory in the French rum system. Its GI is uncompromising. It mandates pure cane juice and excludes molasses entirely. This is a single track agricultural rum economy with strict technical controls.
The Rules of the GI
Geographic Scope
All production must occur within the twenty six municipalities of French Guiana.
Raw Material
Exclusively fresh sugarcane juice. No enrichment, syrup or molasses permitted.
Fermentation
Fermentation must occur in open rounded vats. It relies on spontaneous fermentation using ambient yeasts.
Distillation
Maximum distillation strength is 90 percent alcohol by volume at twenty degrees Celsius. Minimum volatile substances are 225 grams per hectolitre of pure alcohol.
Seasonal distillation is permitted only between the third of July and the fifteenth of April. Columns must include an exhaustion zone of at least fifteen trays and a concentration zone of no more than nine copper trays.
Water
Water must not alter flavour.
Maturation
White rum must rest for a minimum of three weeks.
Brown rum must mature for at least six months. Old rum must age for a minimum of three years and contain at least three hundred and twenty five grams of volatile substances per hectolitre of pure alcohol.
Maximum cask size is six hundred and fifty litres. Minimum bottling strength is forty percent alcohol by volume.
Additives
No sweetening is permitted.
What the GI Protects
It protects a highly specific mainland agricole tradition defined by strict column specifications, seasonal production and high congener requirements.
What the GI Does Not Protect
It does not accommodate molasses or industrial sugar byproducts. Stylistic diversity is limited by design.
Summary / Key Takeaways
French Guiana’s GI is rigid, disciplined and deeply agricultural. It protects a unique mainla terroir through strict technical controls.
Rum da Madeira GI
Madeira is the only non French territory in Europe producing legally recognised agricultural rum. Its GI is strict, cane juice only and culturally aligned with the French agricole model but with Portuguese character and local traditions.
The Rules of the GI
Geographic Scope
All production must occur within Madeira and Porto Santo.
Raw Materials
Exclusively fresh sugarcane juice. Molasses is forbidden.
Sugarcane
Cane must be grown locally on steep volcanic slopes, often by hand.
Fermentation
Fermentation is slow, lasting several days depending on temperature.
Distillation
Maximum distillation strength is capped. Minimum volatile substances are 225 grams per hectolitre of pure alcohol. Stills may be copper pot stills or continuous columns.
Water
Water must not alter flavour.
Maturation
Natural rum is unaged and clear.
Aged rum must mature for a minimum of three years in oak.
Permitted age statements include three, six, nine, twelve, fifteen, eighteen and twenty one years.
Minimum bottling strength is thirty seven point five percent alcohol by volume.
Additives
Natural rum may contain no more than five grams per litre of dry extract.
Fortified rum may be sweetened up to twenty grams per litre. Caramel is permitted for colour consistency.
What the GI Protects
It protects a strict agricultural rum tradition outside the French system, with rigorous certification and mandatory local maturation.
What the GI Does Not Protect
It allows limited sweetening in fortified rum. It does not impose agricultural yield limits like Martinique.
Summary / Key Takeaways
Madeira’s GI is rigorous, disciplined and proudly agricultural. It stands alongside the French islands as a serious producer of cane juice rum.
