Colombia Finca Milan Culturing Nitro 'Toffee' Fermentation Caturra 2025

Finca Milán | Nitro Toffee Culturing Process

Finca Milán is a family-owned coffee farm in Pereira, Risaralda, Colombia. The farm is led by third-generation producer Julio César Madrid Tisnés. Julio focuses his attention on cultivating a wide range of varieties including Caturra, Castillo, Colombia, Bourbon Rosado, Bourbon Rojo, and Catiope and on innovation, investing in fermentation infrastructure and microbial research. This mix of disciplines has made Finca Milán a benchmark for experimental specialty coffee in Colombia. He collaborates closely with his daughter, a biologist, to study the impact of microorganisms on flavor development.

About the Nitro Toffee Culturing Process

The Natural Toffee Culturing process is a unique, mixed fermentation protocol designed to enhance sweetness and complexity. It begins with selective harvesting of ripe cherries which are floated to remove defects. Cherries are then placed in a bioreactor and inoculated with a starter culture (yeast and bacteria). The bioreactor is sealed and injected with nitrogen to facilitate the metabolic processes of the microorganisms. During this time, temperature, acidity, and Brix degrees are closely monitored against past data in order to time the end of the fermentation stage and initiate oxidation.

After leaving the bioreactor, the coffee is dried until reaching 10% - 12% moisture and the fruit is removed to separate the dried outer layers (skin and pulp) from the bean. This method produces a vibrant, fruit-forward cup with notes of banana, pineapple, strawberry milkshake, and a distinct toffee-like sweetness.

Colombian Coffee

Over half a million families dedicate their livelihoods to producing unroasted Colombia green coffee on small farms that dot the country’s volcanic mountain ranges. As the world’s third-largest producing country, the volume, quality, and variety that comes out of Colombia year-round is staggering. Coffee from Colombia is never dull, and with 16 coffee-producing regions along three mountain ranges and two harvests each year, Colombia always has fresh coffee on hand.
