How we roast

Every batch gets measured on a Lebrew RoastSee C1 colour meter. We aim for Agtron 50–60 for espresso, and 61–75 for pour-over.

Espresso and pour-over are roasted differently too. Espresso gets fuller development (23–26%), which gives it more body. Pour-over is roasted faster (13–18% development) to keep the aroma and clarity in the cup.

Coffee Beans

All our coffee beans are freshly roasted in Singapore weekly. Please expect to receive your items in about 3 days after shipment.

About Us

The Coffee Intern is a Singapore-based micro roastery on a mission to make specialty arabica coffee accessible, affordable, and appreciated by all.

We started with Yunnan, bringing the extraordinary taste of this overlooked specialty origin to Singapore at prices everyone can enjoy. We've since expanded into Ethiopia, and we're continuing to source exceptional beans from emerging and underappreciated coffee regions around the world.

Founded by a data scientist, each roast is meticulously crafted using a scientific, data-driven approach — monitoring temperature curves, rate of rise, and bean development to unlock the full potential of every batch.

Whether you're new to specialty coffee or a seasoned enthusiast, we hope to make exceptional coffee from Yunnan, Ethiopia, and beyond accessible, affordable, and always enjoyable.

Our Core Belief

We believe that great coffee should be both exceptional and approachable. That’s why we focus on sourcing extremely high-quality Yunnan single origin coffee beans that not only taste amazing but also support sustainable farming and fair value for producers.

By curating affordable, specialty-grade options, we hope to break the myth that great coffee only comes from faraway regions like Africa or South America. Yunnan coffee deserves its place in Singapore—and in your cup.

Why Yunnan?

Yunnan, China, is quietly revolutionizing the specialty coffee world. With its high-altitude terrain, ideal microclimates, and passionate farmers, the region produces Arabica beans with flavor profiles that range from chocolaty and clean to fruity and floral.

Key Regions We Love:

  • Pu’er – Bold, rich, and full-bodied

  • Baoshan – Balanced and comforting

  • Dehong – Tropical, fruity, and vibrant

  • Menglian – Sweet, clean, and sustainably farmed

We’re continually amazed by how much soul and diversity Yunnan coffee holds—and we want Singapore to taste it too.

From Yunnan to Your Cup

At The Coffee Intern, we bring the best of Yunnan specialty coffee directly to Singapore. No fluff—just well-sourced beans, small-batch roasting, and a data-driven approach to unlocking great flavour.

We strive to make exceptional coffee affordable and accessible. We test, taste, and refine every roast so you can enjoy quality coffee—whether you're at work, at home, or on the go.

Always learning, always improving. That’s the intern mindset.
