“Opened my eyes to blending traditional techniques with modern fermentation methods.

"As a Master Brewer at Hoppingcat Brewery, I joined the academy to deepen my knowledge of spontaneous fermentation and learn cutting-edge techniques and equipment from around the world. The experience has been incredible — I’ve discovered that imagination is the only limit when creating new recipes. In my day-to-day brewing, I’ve improved my temperature control, started experimenting with multiple yeast strains in a single beverage, and even explored how to fuse modern brewing processes with traditional Ecuadorian beverages. Right now, I’m developing a version of chicha produced with industrial processes for commercial sale, blending heritage with innovation.

Federico’s expertise and passion for fermentation are truly inspiring, and the Academy’s well-structured lessons gave me the technical knowledge I needed to confidently experiment. Blending the flavors of the Caribbean with fermentation techniques has not only elevated my menu but has also strengthened my commitment to quality and creativity.
