Abstract

The objective of this study was to characterize the sensory profiles of Amazonian cocoa genotypes evaluated under contrasting seasonal water availability conditions in Mocache, Ecuador. Twenty-eight genotypes from the INIAP Pichilingue Tropical Experimental Station were analyzed, distributed across the wet and dry seasons. The evaluation included soil moisture measurements, physical analysis of cocoa beans, preparation of cocoa liquor, blind tasting by trained tasters, and statistical analysis using principal component analysis, hierarchical clustering, and the Kruskal-Wallis test at the 5% level. The sensory attributes considered were acidity, bitterness, astringency, sweetness, cocoa, floral, fruity, nutty, green, and moldy. The results showed greater water availability during the wet season and a marked reduction during the dry season, a condition associated with changes in sensory expression. During the wet season, specific desirable attributes such as cocoa, floral, fruity, and nutty predominated, with ZAMO 016 PL 21, PANG 006*, NUPA 001 PL 56, NUPA 001 PL 55, and YACU 004* standing out. During the dry season, greater expression of acidity, bitterness, astringency, and green notes was observed; however, NUPA 001 PL 32 stood out for its fruity, cocoa, and sweet profile. Although comparisons should be interpreted with caution because the genotypes were not identical across seasons, the results provide a technical basis for selecting and valuing Amazonian materials with distinct sensory potential.
