"I brewed this one on a rainy Saturday, thinking of a friend who loved both coffee and a good story. There’s a gentle smokiness here, a little sweetness, and somehow it feels like a quiet toast to old memories."

Air Roasted For Smooth Flavor

Roasts and Ships Within Days

Cedar arrives first, like stepping into your grandfather's workshop—wood shavings and wisdom, the scent of things built to last. This coffee knows patience. Chocolate follows, not sweet but earthy, the kind that grows close to soil and remembers it.

Then comes the surprise: sweet tobacco, not smoke but leaf—honeyed and complex, like library corners where leather bindings hold forgotten stories. It's the taste of contemplation, of thoughts that need time to unfold.

This is coffee for the third act of your day, when morning's urgency has passed and evening hasn't yet claimed you. In your careful ritual, mug cradled between weathered hands, you taste what depth means. The cedar grounds you in something solid. The chocolate connects you to earth. The tobacco whispers of transformations—leaf to legend, bean to revelation.

Some afternoons demand coffee that doesn't rush, that tastes like wisdom earned slowly. This understands.

For the best cup at home, start with a 1:16 “golden ratio”: 1g coffee to 16g water. It’s the sweet spot for balanced flavor and body. Adjust from there: pour-over/drip stays close to 1:16; go 1:15 for more richness or 1:17 for a lighter cup. French press often shines a bit stronger (1:14–1:15). AeroPress can be tighter too (1:12–1:15). Use filtered water, grind fresh, and enjoy right after brewing.

Air roasting uses clean, hot air to roast each coffee bean evenly—resulting in a smoother, cleaner flavor without the bitterness or burnt taste you get from traditional drum roasting. Because the beans don’t sit on hot metal, there's no smoky aftertaste—just pure, nuanced notes. It’s a gentler process that lets the bean’s true character shine.

About the Producer

From October through June, across small plots rarely exceeding three hectares between 1300 and 1650 meters, the members of Koperasi Buana Mandiri follow a rhythm born from necessity. Each morning, they harvest cherries from their Ateng, Catimor, and Timor plants, then depulp them by hand at home—a practice unchanged since their grandparents' time. But here's where Sumatra's signature unfolds: still wet with mucilage, at 30 to 50 percent moisture, they carry their beans to collectors who understand what the rains demand. The beans are hulled while still damp—Giling Basah, they call it—a process invented in the 1970s when persistent clouds and downpours threatened every harvest. This unconventional method, stripping parchment at 35 percent moisture before the final drying, creates their distinctive cup: clove spice mingling with graham sweetness. Each sip carries the ingenuity of farmers who refused to let weather dictate their fortune.

Frequently Asked Questions

It’s all in the roast. While most coffee is drum-roasted, which means the beans are scorched as they come in contact with the hot sides of the metal drum. In contrast, we use superheated air for heat transfer—a method used by less than 1% of roasters worldwide. It delivers smoother, more balanced flavor with zero burnt bitterness.

Our air-roasting process reduces acidity and eliminates that harsh, burnt bitterness found in most coffees. That means no gut-bomb effect, no acid reflux, and no regret after your second cup. Even customers who’ve sworn off coffee come back for Ember.

Crazy fresh. We roast in small batches right here in Minnesota and ship quickly—so your beans haven’t been sitting on a shelf for months losing flavor. You’ll taste the difference the moment you open the bag. Plus we stamp our bags with the roast date, not the "best buy" date. Note: Most coffees actually improve in taste in the two weeks following its roast date. If you receive a bag that was roasted 7-10 days from your date of order, we've likely held it to allow for off-gassing and maximum flavor.

We believe great coffee starts at the source. That’s why we build direct trade relationships with farmers who care as much as we do. Better pay for them, better beans for you, and a whole lot more integrity in your cup.

Yes, yes, and yes. Whether you’re team drip, AeroPress, Chemex, or full-on espresso, Ember’s roasts are engineered to perform across all brew methods without losing flavor, depth, or smoothness.

Because once you taste coffee that’s roasted right, sourced right, and doesn’t wreck your stomach… it’s game over for the grocery store brands and chain coffee shops. Ember becomes the new standard.

Specialty-Grade Coffee, Delicious Taste

We only roast the top 5% of beans in the world—carefully selected for clarity, character, and consistency. When you start with exceptional quality, you don't need shortcuts. Every cup begins with a promise: good beans, done right.

We partner with producers who prioritize fair wages, sustainable practices, and long-term relationships. From seed to sip, this coffee is as good for the growers as it is for you. Because doing it right means doing it together.

Air roasting unlocks the bean’s full aroma and complexity—think vibrant notes that actually reflect the origin. It’s a cleaner, more expressive cup that delights your senses from the first inhale to the last warm sip—so you actually taste the coffee's origin and not just the burntness of the roaster drum.

Most roasters use scorching-hot drums that can leave bitter, smoky notes. We air roast with precision and patience—preserving delicate flavors and skipping the scorch. The result? Coffee that’s smooth, never harsh, and always easy on your taste buds.

Air roasting reduces acidity and surface oils, making Ember coffee gentler on digestion. It’s a clean, smooth experience—even black—that doesn’t leave you with jitters or heartburn. Just calm energy and a ritual you can feel good about.

Science-Backed Ingredients

We only roast Arabica beans that score 82+ on the Specialty Coffee Association (SCA) scale—a mark of exceptional flavor, cleanliness, and complexity. Grown at higher elevations and harvested by hand, these beans mature slower, developing deeper sweetness, brighter notes, and a more layered cup. It’s the top 5% of coffee in the world—and you’ll taste why.

Every lot we roast meets SCA’s rigorous grading system, which evaluates 10 key attributes—like aroma, acidity, balance, and aftertaste. Each batch is cupped, scored, and traceable, ensuring not just quality, but integrity at every step. This isn't marketing fluff—it’s a globally respected benchmark for true specialty coffee. We source, roast, and brew with purpose—so you get a cup you can count on.

Clean beans matter. All Ember Coffee is tested and certified mold-free, ensuring a healthier cup without hidden contaminants. Lower-quality coffees often carry higher risks of mold and mycotoxins due to poor storage or processing. We hold every batch to higher standards—because you deserve a cup that’s as pure as it is delicious.
