There's always that one question that comes up at Ember Coffee: "Got anything darker?" For years, I’ve held the line on our roast profiles. I believed in keeping things on the lighter side, allowing the nuances of our specialty-grade beans to shine. But lately, I’ve been reconsidering—and it all started with a piece of history from Michael Sivetz.
The History of Coffee Roast Levels
The world of coffee roasting is filled with different roast levels, each offering its own distinct flavor profile. From light to dark, the way coffee is roasted affects everything—brightness, body, bitterness, and even aroma. Lighter roasts have been favored for their fruity acidity and floral notes, while dark roasts have traditionally offered boldness and deep caramel flavors.
Michael Sivetz, a legendary coffee engineer, published his thoughts on roasting in the 1960s, when he wrote a manual for an 8-pound air roaster—a predecessor to the very air roasters we use at Ember Coffee today. He suggested that the ideal roast temperature was 450°F, rather than the usual 430°F used for lighter profiles. This got me thinking—maybe there was something about the dark roast experience that I hadn’t fully explored.
Experimenting with Higher Roast Temperatures
I’ve always aimed to bring out the best possible flavors in our beans. But the idea of roasting a little darker, somewhere between 450-470°F, sparked my curiosity. Could I create a darker roast that still highlighted the complexity of our beans without overwhelming them with bitterness? Most of the time, dark roasting has been used by commodity roasters to mask poor quality. Roasting dark can easily become a way to hide flaws—but what if, instead, we could balance darkness and caramelization while retaining those incredible, specialty-grade aromatics?
So, I rolled up my sleeves, fired up our roaster, and started experimenting.
Dark Roasts vs. Specialty Roasts: What’s the Difference?
When it comes to dark roast, it’s easy to go too far. The result? A smoky, bitter cup that could be made from just about any coffee out there—no character, no identity. That's why commodity coffee companies often choose the darkest possible roast for cheap beans; it masks their shortcomings. But that’s not what we’re about at Minnesota's Best artisan roaster. Our goal is to celebrate the bean in every way we can, even at a darker roast level.
The trick is in the balance. As I experimented with roasts in the 450-470°F range, I noticed some interesting things. Roasting at this temperature lets me develop deep, rich flavors—think dark chocolate, toffee, even hints of smoky sweetness—but still keeps the unique characteristics of the bean intact. Our air roasting process helps achieve that balance; the even heat distribution and precise temperature control are key to avoiding the bitterness that often plagues dark roasts.
A New Roast Level for the Masses
After months of tweaking, testing, and tasting, I’m excited to announce that we’re introducing a new line of darker roasted coffees here at Ember Coffee. These roasts are going to be in that sweet spot—not too light, not too dark, but just right for those who love a bold cup with depth, while still appreciating the artisan qualities of specialty coffee.
I want these roasts to embody the warmth of our Big Lake coffeeshop, where community and flavor go hand in hand. This isn’t about masking flavors; it’s about enhancing them, adding that extra layer of richness and caramel while keeping the underlying brightness and complexity that makes Ember Coffee special.
Why You Should Give Dark Roasts a Chance
For those of you who’ve been loyal to our lighter roasts—I get it. Light roasts are beautiful and complex, but there’s a whole world of flavor that opens up at higher roast temperatures. A well-done dark roast can be comforting, bold, and surprisingly nuanced. With our new releases, I hope to bring that experience to you—the richness of a classic dark roast without the burnt, one-dimensional taste that’s often expected.
If you’ve been one of those customers asking for something a bit darker, now’s the time to give it a try. You’ll get that boldness you’ve been craving, but with all the careful craftsmanship you’d expect from an award-winning coffee shop. And if you’re in the neighborhood, come down to Ember Coffee in Big Lake and let us brew you a cup of our newest creation. I think you’ll be surprised by what a little extra heat can do.
