Colombia Natural Tartaric Acid Pink Bourbon Cold Room
This Pink Bourbon is produced using Elkin Guzman’s Tartaric Acid Cold Room Natural method, a multi-stage fermentation protocol built around oxidation, organic acid application, temperature control, and cold stabilization. Ripe cherries are first rinsed with cold water, then disinfected and floated in warm water with citric acid before undergoing 24 hours of oxidation in whole cherry. The coffee is then fermented in closed tanks with water and a tartaric acid solution at controlled temperatures to guide pH, microbial activity, and aromatic development. After a second oxidation stage, the cherries are sealed in GrainPro and placed into a cold room, slowing fermentation and locking in structure and clarity. The coffee is then slowly dried in parabolic dryers over several weeks and stabilized before milling, allowing the acidity-driven process to fully integrate while preserving precision, depth, and cup definition.

About the farm: Selected cherries are picked with a minimum ripeness of 90% and an average Brix level between 20–24. Our pickers are trained to meet this standard as the first quality filter. Once the coffee arrives at the processing station, it’s rinsed with water at 10–15°C to remove impurities, followed by a floating process using water at 35°C with citric acid for disinfection and separation of defective cherries. The coffee then undergoes 24 hours of oxidation in cherry, followed by a 30-hour fermentation in closed tanks with water at 35°C and tartaric acid solution. Afterward, it goes through a second 12-hour oxidation stage, is drained for 30 minutes, and then placed in Grainpro bags inside a cold room at 6°C for 30 hours.
Drying time: The coffee is dried in parabolic dryers for 20–28 days

Producer Q & A
How did you come into working in coffee?
I grew up surrounded by coffee farms in Palestina, Huila, so you could say it’s in my blood. I’ve been involved in coffee production for over 15 years now, and it was my curiosity about fermentation and coffee processing that really drove me deeper into this world. My family has been involved in coffee farming for generations, but my passion lies in pushing boundaries and experimenting with different fermentation methods to unlock new flavors.
What makes this harvest or lot different from others?
This harvest is special because we’ve refined our controlled fermentation processes even further. We’ve developed specific protocols to bring out unique flavor notes, and we’ve been able to apply these to both traditional and exotic varietals. This particular lot showcases the balance between innovation and tradition, with clean, distinct flavors that reflect our deep commitment to quality.
What would you say separates your coffee from others?
Our coffee is set apart by the meticulous attention we give to fermentation and post-harvest processes. We’re constantly experimenting and fine-tuning techniques that result in unique and diverse flavor profiles. Each coffee we produce carries its own signature, reflecting the care, innovation, and research behind it. We also focus on sustainability and traceability.
What does your day consist of managing the farm or farms?
My day usually starts early with a check on the fermentation tanks and drying beds, ensuring that the processes are going smoothly. I’m constantly monitoring the coffee cherries during their different stages of fermentation. Communication with my team is key, we work closely to oversee every detail, from picking the ripest cherries to controlling fermentation times and temperatures. I also dedicate time to research and development, always exploring new fermentation techniques to keep improving.
What opportunities are you looking for from people who buy your coffee or work with you currently?
I’m always interested in buyers who are as passionate about innovation and quality as I am. I’m looking for long-term partnerships with people who appreciate the complexity of the processes we use. It’s rewarding to collaborate with partners who provide feedback, share insights, and help us refine our methods. Transparency and trust are important to me, and I seek those values in any collaboration.
Where does your sense of passion for coffee come from?
My passion comes from the endless possibilities that coffee offers. Coffee is alive, it evolves, changes, and surprises you every season. My passion grew even stronger when I started experimenting with fermentation and saw how different techniques could enhance flavors in ways we hadn’t imagined. Every harvest is a chance to innovate and discover something new, and that excitement keeps me driven.
Are you looking to grow relationships with long-term partners?
Yes, long-term relationships are essential to my work. They allow for deeper collaboration and a mutual understanding of expectations and goals. I believe that working closely with long-term partners helps both sides improve, it’s not just about selling coffee; it’s about creating a shared journey towards better quality and sustainable production.
Feel free to share anything on your mind about the industry or yourself. We sell not just to consumers but to the industry, which often looks at what we buy and tries to buy it too, benefiting everyone.
I believe the coffee industry is evolving rapidly, especially in terms of how producers and buyers collaborate. There’s more appreciation now for the complexity behind coffee production, particularly with innovative processes like fermentation. I’m hopeful that this trend will continue, allowing producers like myself to push the boundaries of what coffee can be while also ensuring that sustainable and fair practices become the norm. And finally, I want to thank you and your customers for buying our coffees.
