The Free Bacchus Story

Adrien and Jean Neisson founded the distillery at Le Carbet in 1931. Jean was a trained chemical engineer and spent his time on the distillation itself. The square Zépol Karé bottle the house is recognised by arrived at the start of the 1950s.

What comes out of it is rhum agricole, made from fresh cane juice pressed within hours of cutting. Most rum in the world is made from molasses, a by-product of sugar refining that is already several steps removed from any particular field. Agricole’s supply chain is short enough to check, which is the entire reason this category can be verified at all.

The estate converted to organic farming in 2013 and released the first organic AOC rhum in 2016. That is harder than it sounds: the Martinique appellation dictates cane varieties, harvest windows, fermentation and distillation parameters, and an organic certificate has to fit inside all of it without breaking any.

The style is dry and grassy in a way molasses rum never is.

Cane in tropical agriculture is normally heavily treated. A certified organic estate distilling its own harvest under an appellation that specifies the method is about as checkable as a spirits supply chain gets — and checkable is the only thing this site can actually score.

Why it’s remarkable

Cane juice
pressed within hours, not molasses
Most rum in the world is made from molasses, a by-product of sugar refining already several steps removed from any particular field. Rhum agricole is made from fresh cane juice. The supply chain is short enough to check.
First
organic certification inside the Martinique AOC
Harder than it sounds: the appellation dictates cane varieties, harvest windows, fermentation and distillation parameters. Organic certification has to fit inside all of it.
Spirit Gold
at the IWSC 2026, for the organic Bio Rhum
The unaged white, bottled at 52.5%, was entered as certified organic by Ecocert, and it is the rum the certificate covers. The judges found grass, fresh herbs and white melon.

Drinking now
The Bio Rhum is unaged and ready on release. It is the clearest expression of the cane, the better introduction to the style, and the bottle the organic certificate covers.
Serving
Blanc is built for a ti’ punch — cane syrup, lime, no ice needed. Aged expressions neat at room temperature.
Availability
Small production and limited allocation outside France. Specialist spirits retailers rather than general stockists.

Dry and grassy, with a vegetal freshness molasses rum never has. Distinctive rather than sweet.
Pairs with
Grilled pineapple, dark chocolate, or a simple ti’ punch.
Price bands are approximate and move with vintage, market and region. They are a guide, not a quotation.
