JB Liberica Excelsa - Filter

2 reviews

From our roaster’s perspective, this coffee feels like a bridge between memory and discovery. The first time we experienced Excelsa, we were struck by its natural sweetness – rare in today’s specialty coffee world. That same sweetness defines this cup, coating the palate and lingering much like the comforting herbal teas of our childhood.

On top of that, the profile delivers ripe red apple and Asian mango, bursting with juicy character and balanced by a bright but controlled acidity. As the cup cools, a gentle jasmine floral note appears, softening the intensity and adding elegance. The velvety body leaves more sweetness than acidity in the aftertaste, creating a coffee that feels both familiar and exquisite – a rare find that reminds us why we roast.

The producer, Reza Nurullah, has been experimenting with yeast fermentation in coffee since 2016 – long before it became popular. Back then, his work was often dismissed as “too strange,” but he stayed committed to pushing boundaries and refining his process. Years later, when similar coffees began appearing in competitions, people finally started to recognize the value of his approach.

By 2025, Reza’s coffee was competing internationally, with one lot earning 4th place at the World Barista Championship and achieving the highest score in the Open Service category.

For this release, Reza processed a mixed species of Liberica and Excelsa, using a carefully managed honey process with yeast inoculation. To protect the quality of these delicate beans, he extends the drying phase to around 6 hours of sun per day, preventing unwanted phenolic or moldy notes. The result is a clean, sweet, and floral cup with a long-lasting finish.

Not long ago, Liberica and Excelsa were undervalued and often blended with robusta for the local market. Today, thanks to Reza’s dedication and innovation, these species are proving their place in specialty coffee.

From the highlands of Central Java, this coffee offers a taste of nature in its purest form.

Grown around Mount Telomoyo and the Temanggung region, these coffees thrive in fertile volcanic soil, cool mountain air, and a landscape shaped by generations of farming tradition.

What makes this region truly special is how the coffee is grown. Instead of clearing land, farmers cultivate coffee under the shade of tall forest trees — an agroforestry system that protects biodiversity, preserves the soil, and helps prevent deforestation. The result is not only better for the environment, but also better in the cup.

On the slopes of Mount Telomoyo, villages like Sepakung benefit from ideal growing conditions that allow the cherries to mature slowly, developing vibrant and expressive flavors. Combined with the rich agricultural heritage of Temanggung, these coffees often show lively tropical and citrus notes, balanced with delicate florals and a refined sweetness.

Behind every cup are dedicated farmers like Mbah Bedjo, whose knowledge and care bring out the best of this land.

A coffee shaped by volcanoes, forests, and a commitment to farming in harmony with nature — bright, elegant, and full of life.

Frequently asked questions

ABout the coffee

Yes. We roast our coffee in small batches every week. After roasting, the beans are rested for at least one week before shipping. This allows them to reach optimal freshness and ensures they’re ready to brew when they arrive.

After roasting, coffee beans naturally release carbon dioxide in a process called degassing. During this resting period, the flavors continue to develop and stabilize. If the beans are used too soon, the coffee may taste unbalanced and produce excessive gas during brewing, leading to suboptimal extraction. In addition, dialing in becomes inconsistent during this phase, making it more difficult to achieve stable and repeatable results.

Typically, our coffee performs at its peak between 2 weeks and 3 months after roasting, when the flavors are fully developed and stable.
