Basket vs box fermentation

Both are contained fermentations. Baskets suit the small volumes a single smallholder produces; boxes suit consolidated centres.

Side by side

 Basket fermentationBox fermentationWhy it matters
Typical batch sizeTens of kilograms — one farmer's harvest.Hundreds of kilograms to a tonne.Below roughly 100kg a mass struggles to generate and hold the heat fermentation needs. Baskets are the small-volume answer to that problem.
Heat retentionPoor without insulation. Lining with banana leaves and covering is essential.Good. Wooden walls and depth hold heat well.Under-heated fermentation is the main small-lot failure, and it reads in the bar as green, astringent under-fermentation.
TraceabilityComplete to the individual farmer.Pooled across many farms in most centralised operations.Basket fermentation is what makes single-farm traceability possible at smallholder scale.
ConsistencyVariable, depending on the individual operator's practice.More consistent under a single trained operator.

Choose Basket fermentation when

Where farmers ferment their own harvest and traceability to the farm is the objective.

Choose Box fermentation when

At a centralised fermentary handling consolidated volume, where consistency matters more than individual attribution.
