Farm Stories: Bioma Cafe, by Marcelo Assis
In our regular Farm Stories series, we take a deep dive into the story behind the farm, and farmers, who produce the great coffees that we get to roast and share with you all.
Meet Marcelo
Marcelo Assis is one half of the partnership that makes up Bioma Cafe - a small farm on the cutting edge of specialty coffee production in Brazil, and a producer that we're thrilled to be able to partner with here at Kea.
Bioma Cafe is a joint venture between Marcelo Nogueira Assis and Flavio Marcio Silva. The pair are part of a new generation of farmers and producers in Brazil, who are committed to improving coffee quality and producing high quality specialty grade lots - something that Brazil in general hasn't been very well known for in the past.
The pair initially joined forces in 2001. Mercelo, a recent graduate from a leading agricultural school, had a passion and vision to create a small farm with a dedicated focus on producing the highest quality specialty coffees.
What followed next was a 9 year search for the perfect terroir.
In 2010, the pair settled on their dream lot - a 229 hectare lot in Cerrado Mineiro.
The farm sits on a plateau at 1200 meters above sea level, and this small but mighty team have spent the subsequent years planting some rare and unusual varietals (more on that later!) and pushing boundaries with new processing techniques to produce some of the regions top coffees.
Most recently, Bioma Cafe won 1st place in the 2024 Cup of Excellence competition in Brazil in the experimental processing category with an anaerobic fermentation lot with an impressive cup score of 93 points.

‘coffee for a better future’
This is Bioma Cafes motto, and the driving ethos behind everything they do.
Mercelo and his small team are dedicated to improving the health of the soil - something that Mercelo with his extensive agricultural training knows all about!
From extensive cover crops, to highly customized nutrition plans to rejuvinate and replanish the soil, their goal is to ‘elevate the terroir’ by treating each plot individually.
Unlike other, larger farms in Brazil, they don't believe in simply applying the same blanket fertilizers no matter what. Instead, they have divided the farm into 6 different zones so that they can better tailor their soil enhancement programs to the specific nutritional needs of each individual plot.
They have also been working on producing their own fully organic fertilizers, which this year (2025) will make up over 60% of their total fertilizer use across the whole farm. Their goal is to build on that and to further reduce their reliance on artificial or chemical soil supplements.
But their commitment to continual improvement doesn't stop at the soil.
The pair are equally passionate about investing in their people and also their technology, so that they can continue to push the boundaries of specialty coffee production, and elevate the region to new heights.


Exploring unusual varietals
One of the things you'll notice pretty quickly with Bioma Cafe, is that they are not afraid to experiment.Whether that's new experimental processing techniques (like their 2024 CoE winning lot, with a 72 hour anaerobic fermentation followed by 15 days drying in a greenhouse), or highly unusual varietals like Arara and Paraiso.Armed with Marcelo's extensive agricultural training, and the distilled knowledge from generations of family members who made their living in coffee, the Bioma Cafe team truly are at the very front of a new wave of specialty coffee production in Brazil.We were lucky enough to get our hands on a very small quantity of a recent Paraiso lot. If you've never heard of this varietal before then don't worry, because neither have most people.Paraiso was developed in 2012 by by EPAMIG (Minas Gerais Agricultural Research and Development Company) when they crossed a Timor Hybrid with a Yellow Catuai. It's highly productive, disease resistant, and starts producing cherry after just 2 years.The lot that we've been playing with is light and citrusy, with notes of lime, peach wine, orange and hints of mint on the finish. A super interesting coffee with a lot going on. Grab a bag below while it lasts!
