Pure Single Rum, Single Blended Rum: classification by still type

Why classify rum by still type?

White, gold, brown, dark: that's still how many shelves sort rum today. This says little about production and character, since colour can be adjusted with the cask, filtration, and caramel colouring. Italian merchant and bottler Luca Gargano, head of Velier, wanted a system that tells the story of how a rum was made. Together with Richard Seale, who runs the Foursquare distillery on Barbados, he developed a scheme based on still type in the mid-2010s.

The idea comes from the whisky world. There, Single Malt from the pot stills of one distillery has long been distinguished from grain whisky made in columns and from blends of different houses. Rum lacked such a vocabulary. Gargano and Seale adapted it to the rum world, where many distilleries run pot stills and columns side by side and blend both distillates themselves.

Pure Single Rum and Single Blended Rum

Pure Single Rum is the category with the narrowest definition. It refers to rum distilled entirely in pot stills or other batch-operated equipment, and only at a single distillery. Hampden in Jamaica or Guyana's wooden pot stills produce such rums. Under the name Habitation Velier, Velier has released many bottlings using this term, which the company states are unsweetened and uncoloured.

Single Blended Rum also comes from a single distillery, but combines pot still rum with column rum. This is typical of Barbados, where Foursquare and Mount Gay both operate both types of equipment. The term clears up a common misunderstanding. Here, 'blended' doesn't mean rums from different houses or countries are mixed, but that two types of stills from the same house come together.

Traditional Rum, Rum, and the Agricole Variants

The classification calls rum from traditional columns, such as the Coffey Still, Traditional Rum. These stills run continuously but separate less sharply than modern multi-column equipment, letting more aroma through. Finally, the scheme labels distillates from modern multi-column stills, which can come close to neutral spirit, simply as Rum. This category includes many light Spanish-style rums.

For rum made from sugarcane juice, the classification has its own variants, such as Pure Single Agricole Rum for juice-based rum from pot stills. This makes it easy to tell apart a juice rum from the pot still, an agricole from the Creole column, and a molasses rum from Jamaica at a glance. The two axes are raw material and still type. These two factors shape a rum's character most strongly, even before the cask comes into play.

What the Gargano Classification Does and Doesn't Do

The Gargano Classification is a private system. No law mandates it, and no authority audits it. In the EU, the Spirit Drinks Regulation still governs the designation, and it makes no distinction based on still type. Anyone who puts Pure Single Rum on a label is therefore making a producer's claim. Its value depends on trust in the distillery or bottler using it.

Still, the scheme has changed the conversation around rum. It shifts attention from colour and age statement to production method, and helps explain why two rums of the same age can taste so different. One possible misunderstanding remains: column rum might seem inferior as a result. That's not the intent. The classification describes how a rum is made, not how good it is.

How do you use this when shopping? If none of these terms appear on the bottle, it's worth checking the distillery's website. Many producers state there whether their rum comes from a pot still, a column, or both. If there's no mention of distillery or equipment at all, it's often a blend of several origins. That's not prohibited and can taste great, but it says little about the rum's journey. Anyone wanting to explore different styles should compare a Pure Single Rum, a Single Blended Rum, and a light column rum side by side. The differences in aroma and mouthfeel often explain the still type better than any chart.
