When we hear "Colombia coffee," we imagine a rich aroma, vibrant fruity notes, and high quality. But not all Colombian coffee tastes the same. The key to a complex, modern sensory profile is often... fermentation. And one of the most advanced fermentation methods is Culturing, created by Julio Andres Quiceno – a pioneer of innovative coffee processing techniques. It is this method that gives light roasted coffees exceptional intensity and makes them perfectly suited for pour-over brewing methods.
What is Culturing fermentation?
Culturing is a controlled fermentation of coffee cherries using selected cultures of microorganisms (mainly yeasts and lactic acid bacteria), fruit substrates, and added nitrogen. This process was developed over more than 3 years of research in Colombia, including in cooperation with the Universidad de los Andes. Julio Andres' goal was not just to enhance the flavor profile – he wanted to transform the bean, modifying its structure and the bioavailability of aromas at a cellular level.
Nitrogen plays a key role here: it helps regulate the pressure inside the bean cells and their permeability, without the risk of overheating or damage. Thanks to this, microorganisms can deeply penetrate the structure of the coffee cherry, and the fermentation effects are more intense and stable.
Fermentation based on fruits and cultures from previous harvests
In the Culturing method, fruits are used as substrates – not to impart their flavor, but as a source of sugars and aromatic compounds that microorganisms process. Each yeast strain reacts differently to a given substrate. The right combination allows for the production of specific chemical compounds such as decalactones – responsible for distinct peach and lychee notes.
The microorganisms are not random. Julio uses cultures from previous fermentations that are already adapted to the environment. This ensures consistency of the profile, even though each batch of coffee comes from a different harvest.
The process is precisely controlled: temperature, pH, oxygen level, pressure, and humidity are monitored. All this is to achieve maximum aroma saturation – without burdening the bean.
Why is this method conquering the world of specialty coffee?
Culturing gives producers a tool that enables them to create unique and distinctive flavor profiles – especially sought after in the specialty coffee segment. As a result, we get coffees that, even after light roasting, delight with intense aroma and sweetness.
Thanks to this method, roasters can afford a lighter roast while maintaining full flavor and structure. This makes Culturing-fermented coffees ideal for pour-over brewing (e.g., V60, Kalita, AeroPress), where purity and complexity of taste are most easily perceived.
The effect in the cup? An intense, fruity explosion
Coffees processed with the Culturing method offer incredibly clean and concentrated profiles. Depending on the botanical variety and the substrates used, one can expect:
-
peach, lychee, mango
-
floral notes (jasmine, rose)
-
creamy body and high sweetness
It's a full-fledged sensory experience that requires no additives – the coffee itself tastes like a dessert.
Where to buy coffee with Culturing fermentation?
At the Coffee Mates store, you will find fresh, light roasted pour-over coffees from Colombia, created using this method:
Summary
The Culturing method is the future of coffee processing. It combines scientific precision, microbiological knowledge, and the artistic intuition of the producer. If you are looking for coffee that captivates with its depth of flavor from the very first sip – be sure to try a light roasted, Colombian specialty coffee created using this method.
