**3. Conclusion**

The ethanol yield in the alcoholic fermentation process of cabuya azul juice was 47.4%, which represents approximately 93% of the theoretical yield of ethanol production by fermentation, observing that it meets the minimum yield, 45%, that requires a fermentation industry for the production of liquors, therefore, the yield obtained in the investigation is very good.

The experimental results showed that the yield of ethanol in the fermentation process of cabuya azul meets the minimum requirements for its industrialization, it is a product of biology from renewable biomass, which will allow this natural resource to be used in liquor production as part of a sustainable development program.
