The Magic of Dark Roast Coffee Beans: Ordinary Coffee Can Be Enchanting! Flavor Characteristics of Dark Roast Coffee_ How Much Do Dark Roast Coffee Beans Cost

On a stormy afternoon, a customer came in and ordered a cup of Blue Mountain coffee. After brewing it, I took a sip. That charming, fresh, elegant subtle fragrance, accompanied by cedar aroma, finally turned into the sweet taste of chocolate. With the rain outside, it was simply refreshing and satisfying, awakening my taste buds. I really love the sweet aftertaste of dark roast coffee beans. And this sweetness is different from the tart, sweet-and-sour sensation of light roast beans.

However, which is better: dark roast or light roast?

This question has been debated for over half a century. After all, tastes vary, and I love both.

Many people often dismiss dark roast beans as completely worthless, believing that the shiny, oily, dark-roasted beans use carbonization to cover up the taste of bad beans, such as rubbery, muddy, rotten, and earthy flavors. Some roasters do exactly that: unwilling to spend money on good beans, they use a dark roast to bury the off-flavors of poor lots. But we cannot reject everyone on that basis, especially the small, highly skilled roasting companies that spare no expense to buy hard beans and painstakingly study the art of heavy roasting. They deserve real respect.

The sweet aroma of dark roast coffee and light roast coffee are clearly different. Dark roasted beans are deep and thick, with a heavy aftertaste and an enveloping fragrant sweetness, mainly felt at the root of the tongue and the throat. Light roast beans are light and bright, with an uplifting sweetness and a shorter aftertaste, their sweet-and-sour aromas mainly presented on the tip of the tongue, both sides of the tongue, and in the nasal cavity.

Dark roast and light roast coffee have different heat levels, temperatures, roasting times, and heat curves, causing sugars to undergo different degrees of degradation, polymerization, and other complex chemical changes.

Coffee beans themselves are not bitter; the roasting method determines whether coffee is bitter or not. Chlorogenic acid lactone and phenylindane are the two heaviest bitter compounds in coffee. Both are degradation products of chlorogenic acid in raw coffee beans during roasting, and both are generated at different stages of heat.

Chlorogenic acid lactone is generated during the light to medium roasting stage before the second crack. If roasting continues past the second crack, chlorogenic acid lactone further degrades into phenylindane, which has a heavier burnt bitterness, making it the bitterness-causing substance in dark roast espresso.

Truly good dark roast coffee beans are rare and usually carry a smoky flavor. Only by correctly controlling heat and time can the production of the bitter compound phenylindane be greatly reduced, making the oily beans mellow and soothing to the throat when fresh, without any burnt bitterness.

In the heat of summer, a cup of light roast coffee can stimulate the taste buds and boost the appetite. On a stormy day like this, though, why not have a cup of mellow dark roast coffee.

The FrontStreet Honduran coffee and Brazilian Red Bourbon are also roasted on the darker side for a deep, sweet base, while the FrontStreet Indonesian Mandheling brings a low-acid, full-bodied cup of herbs and dark chocolate.
