In tropical cold weather, the grapevine presents phenological disorders, difficult agronomic disfavoring vintage quality. With the purpose of establishing phenological cycles determined the duration of the different phases of the development cycle of the grapevine, cv "Cabernet Sauvignon" (Vitis vinifera L.) in the vineyard Ain-Karim (5º39` N, 73º95' W), 2110 masl. We determined the average duration of sprouting (SP), flowering (FL), veraison (VE) and vintage (VI) periods from pruning, and the total cycle of growth, according to the phenological scale Biologische Bundesanstalt Bundessortenamt Chemise (BBCH). To set the average of the process was considered when the plants reached 50% of each event. Determining growing degree days (GDD) support the temperature record by a datalogger. Phenological data were subjected to a descriptive analysis as means and standard deviation. The duration of the period between pruning (PR) and vintage (VI), with average temperature of 17.87 ° C, had a duration of 183 days after pruning (DAP), accumulating growing degree days 1458.1 (GDD). Flowering occurred at 50 days after pruning (DAP), accumulating 397.7 GDD. Veraison 122 was presented to the accumulation of 578.2 DAP with GDD. While from veraison to maturity 478.9 GDD accumulated in 62 days. Under Sutamarchán agro-climatic conditions, during the investigation, collects, on average, 7.98 degrees daily growth, which implies that for the Cabernet Sauvignon, the total duration of the phenological cycle is 184 days, accumulating 1458.1 GDD.
