The research was developed in Chaguarpamba canton, belonging to the Loja province (Ecuador) with the objective to determine the influence of the variety, the altitudinal floor, and technological processes on phenolic compounds, antioxidant capacity, and organoleptic quality of coffee. The characterization of 25 farms belonging to the Association of Agricultural Producers of the Chaguarpamba canton (APACCH) was carried out. The results indicate that coffee cultivation is established in agroforestry systems and is the main agricultural resource for producer families. There are other crops such as sugar cane, corn, cassava, banana and fruits, developed in small areas whose production is for internal consumption or subsistence. Crop management is done in a traditional way, with little or no technological application; the coffee varieties that are most cultivated are Catuaí, Caturra, and Tipica, whose yields are similar. The cluster analysis typifies the farms in 4 groups. One group is made up of farms 1,10,17,5,13 and 15, which are characterized by cultivating the same varieties of coffee, obtain similar yields in cherry coffee and employ traditional management and care practices. The farm 13 located at 1233 m.a.s.l. cultivates the Catuai variety, its postharvest process is in wet parchment with a cup quality of 83.80 points, presenting herbal notes, chocolatey, citrus, toasted almond. The highest content of phenols and antioxidants was determined in the coffee from farm 10 that reported 5469.2 mg AG / 100 g coffee in the Caturra variety and 404.47 uM Trolox / g coffee in the Tipica variety (wet parchment on a flat medium) results that show that technological processes influence bromatological analyzes, antioxidant capacity, and cup quality. 64% of the coffee farms in the Chaguarpamba canton are sustainable. However, they present critical values related to education and ecological awareness, variables that could negatively affect in the future the sustainability of coffee farms in the area.
