Does Downstreaming Create Value the Market Can See? A Blind Discrimination Test of Fermented Versus Unfermented Cocoa Nibs Among Food and Beverage Buyers

Abstract

Downstreaming (hilirisasi) is a central pillar of Indonesian industrial policy and is increasingly applied to agricultural commodities at the village level. This study examines whether value added through cocoa fermentation can be detected by potential buyers and translated into demand. Cocoa nibs from a single farm and harvest lot were divided into fermented and unfermented portions, then roasted and winnowed identically. Twenty-five food and beverage businesses in Aceh Tamiang—15 coffee shops, 5 bakeries, and 5 micro cocoa enterprises—received both samples blindly in coded containers and were asked to identify the fermented sample. All respondents identified it correctly (p < 0.001), with a 95% confidence interval for the underlying detection rate of 86.3–100%. Identification was primarily attributed to the fermented sample’s sweeter taste, stronger aroma, and drier texture. Detection translated into purchase among 15 outlets (60%). However, demand modeling based on observed offtake indicates that all 25 outlets would absorb only approximately 5.6 tons of dry beans annually, equivalent to about 3% of the cocoa volume currently sold unfermented in the regency. The findings confirm that fermentation creates detectable quality value but demonstrate that processing capacity alone is insufficient. Without deliberate market expansion beyond local channels, downstreaming can validate quality without generating sufficient market absorption.
