Abstract

TEIXEIRA, A. A.; CARVALHO, A.  and  FAZUOLI, L. C.. Cup quality evaluation of Coffea canephora and Coffea congensis cultivars. Bragantia [online]. 1979, vol.38, n.1, pp. 37-46. ISSN 1678-4499.  http://dx.doi.org/10.1590/S0006-87051979000100005.

Coffea canephora and C. congensis cultivars were evaluated for morphological and cup quality characteristics, comparing seed samples from four localities of the State of São Paulo. A five point scale, developed in Angola for testing cup quality of C. canephora, was used. C. canephora cv. Kouillou, from the State of Espírito Santo, and C. arabica cv. Mundo-Novo were used as standards. According to morphological characteristics 46% of the clean coffee samples were classified as C. arabica and 36% as C. canephora. The percentage of peaberries varied from 10 to 50% for C. canephora and from 20 to 40% for C. congensis, while Mundo-Novo gave 15% of this seed type. In relation to the cup quality eight samples proved to be significantly better than Kouillou. However none of the samples showed to be better than Mundo-Novo. A positive and significant effect of pulping on cup quality was observed when comparing 17 pulped coffee samples to the corresponding samples without pulping. Furthermore an effect of locality on cup quality was observed. The best cup quality was obtained from the pulped coffee samples of Ribeirão Preto locality. The analysed results pointed also out that C. canephora and C. congensis cultivars can give beverages of similar cup quality.
