Physicochemical parameters of arabica fermented coffee in different altitudes

The coffee quality interacts with different processes, techniques, analyses, and concepts. This study applied six different forms of wet fermentation to coffee from different altitude ranges to understand how coffee quality interacts with the physicochemical profile and its possible relations with sensory variables. Statistical analysis was performed through combined analyses of variance of the experiments, and the means were compared by the Tukey test considering the significance level of 5%. Regression models were tested by the F-test and the parameters by the t-test, followed by Pearson correlation analysis between the sensory and physicochemical characteristics and between physicochemical variables. The results indicate a correlation between sensory and physicochemical variables for total titratable acidity and indicate that these compounds are affected by the manner of fermentation appliedas well as the edaphic and climatic conditions.
