Watermelon, Orange Blossom, Candyfloss

We don't typically do co-ferments, but something this deliberate is worth celebrating. Juan David Puerta is a food engineer, rather than a farmer by inheritance. His project, Sens Coffee, is built on the idea that coffee should make you feel something. At Finca La Sirena, perched at 1,350 masl in Colombia's coffee region, climate change is threatening farms that once thrived. Juan David's response embodies reimagining processing, rather than fighting the altitude.

Here, pulped coffee undergoes osmotic dehydration in a glucose-watermelon solution, which ensures a controlled, molecular-level technique that locks fruit flavour into the bean. The result is watermelon, orange blossom, and candyfloss flavor notes. A playful coffee that doesn't skimp on depth, this is a cup that proves co-fermentation, when done with this much intention, is a craft.

ABOUT

For the London Coffee Festival, we're releasing a single origin that transgresses the boundaries of coffee with a Watermelon Co-fermented Honey from Finca La Sirena. We don't typically do co-ferments, but something this multidimensional and deliberate deserves a celebration.

Juan David Puerta is a food engineer, rather than a farmer by inheritance. With a degree in Food Science and Engineering, he spent years working with coffee companies and cooperatives across Colombia's coffee region before founding Sens Coffee in 2022. The name Sens nods towards a sensory element, and the philosophy that coffee should make you feel something.

His farm, La Sirena, sits at 1,350 metres above sea level. Fifty years ago, this was prime Arabica altitude. Today, climate change is rewriting the rules, threatening both production and cup quality. Juan David's response embodies reimagining processing, rather than fighting the altitude. He now works with other farmers across the region to share what he's learned.

The cherry is selectively hand-picked, floated, then undergoes three days of dry fermentation in closed tanks before pulping. The pulped coffee is submerged in a concentrated glucose and fresh watermelon solution, with Brix levels adjusted to trigger osmotic dehydration. The water migrates out of the coffee into the higher-concentration solution, while watermelon's volatile flavour compounds are driven into the bean. After two days, the coffee dries on traditional sun beds for around 15 days. The result is watermelon, orange blossom, and candyfloss flavor notes. A playful coffee that doesn't skimp on depth, this is a cup that proves co-fermentation, when done with this much intention, is a craft.

ETHICAL COFFEE SOURCING

Just like our approach to roasting and training, we source coffee in such a way that prioritises empowering people who are disadvantaged or disenfranchised.

Every sourcing decision is made intentionally in order to maximise the impact for the producers.
We focus these decisions around 3 main principles:

REHABILITATION

In line with our mission in the UK, we support the rehabilitation of coffee producers previously involved in conflict, crime or the drug trade. We’ve been working with a project in Colombia which supports farmers who were previously members of paramilitary groups, and want to move away from growing illegal plants for the drugs industry and instead produce coffee. This allows them to have a steady, sustainable income which provides for their family and creates stability within their community.

Sustainable Initiatives

Economic and environmental sustainability are important issues at every stage of the coffee supply chain.

We work with Caravela, who on top of paying farmers up front, have an on-the-ground team to work with farmers improving their farm yield and reduce carbon emissions.

We also work closely with Raw Material CIC, who reinvest all profits at origin.

Female Economic Empowerment

We support the promotion of female coffee producers to improve gender equality in the industry. In an industry where women do most of the labour but rarely hold positions of power, we want to help reset the balance. We’ve built a relationship with Patricia Coelho, a female producer in The Pinhal Region in Brazil, to create our house espresso blend, The Block. We now do a lot of business with Patrica, giving her the capital to invest in producing better and better coffee and thereby access the speciality market. 2023 marks our third year working with Patricia.
