Sens Coffee Pioneers
Juan and Geraldine Puerta on Finca La Sirena, Quindío. Among the first producers worldwide to use osmotic dehydration in coffee.
Real Aromas
No artificial flavors. Aromas develop naturally during fermentation, when the bean absorbs notes from real ingredients.
Limited Editions
Each lot is small and seasonal. When sold out, the next batch is months away — or might never return.
The Co-Fermented Profiles
Each profile uses a different natural ingredient during fermentation. Result: distinct, complex cups that taste nothing like a "regular" coffee.
Apricot OD
Castillo, osmotically dehydrated with fresh apricots. Sweet, ripe, fruity. Our bestseller and the gateway to co-fermentation for most customers.
Azahar
Castillo, co-fermented with coffee blossom (Azahar). Jasmine, floral, honey sweetness. Limited edition — when it sells out, it's gone for the season.

Golden Papayo
Papayo varietal, 240-hour Carbonic Maceration, Natural Process. Chocolate, cacao nibs, vanilla. For drinkers who want more body and depth without sacrificing clarity.
Frequently Asked Questions about Co-Fermented Coffee
What is co-fermentation in coffee processing?
Co-fermentation is a processing technique where natural ingredients — fruits, flowers, spices, yeasts — are introduced during the coffee's fermentation stage. The bean absorbs aromas from these ingredients through osmotic exchange. The result: a coffee that tastes like its origin AND like the added ingredient, without any artificial flavors.
How does it differ from washed or natural process?
In washed processing, the fruit pulp is removed and the bean ferments in water alone. In natural processing, the bean ferments inside its own fruit. In co-fermentation, additional ingredients are introduced during fermentation. All three are legitimate specialty processes — co-fermentation is the newest and most experimental.
Who is Sens Coffee / Juan Puerta?
Sens Coffee is the producer project of Juan and Geraldine Puerta at Finca La Sirena in Quindío, Colombia. They are among the pioneers of osmotic dehydration applied to coffee. Garza Coffee imports their lots directly and roasts them fresh in Berlin.
Are the aromas natural or artificial?
100% natural. Co-fermentation uses real fruits, real flowers, real spices. The bean absorbs aromas through osmosis during fermentation. No synthetic compounds, no artificial flavoring. The result is a coffee that genuinely tastes of apricot, blossom or lulo because those ingredients were present during processing.
Which co-fermented coffee should I start with?
Most people start with Apricot OD. It's the most approachable: sweet, ripe, distinctly fruity but still recognizable as coffee. Once you've enjoyed it, try Azahar for floral, then Spice Cosmic for complexity. If you prefer fuller-bodied profiles, Golden Papayo (Carbonic Maceration) is the way.
