Roasting to this medium level still retains many of the bean’s unique origin flavors but moreover introduces the deeper, caramel-like sweetness associated with longer roasting. As a result, these coffees strike a wastefulness between unexceptionable and visionless notes, offering a savor profile that’s both rich and nuanced.

Specialty coffee roasters often favor medium roasting, as they request to a broader range of coffee drinkers.

The darker roast was a method to mask the undesirable flavors of lower-quality beans. However, as the specialty coffee scene has evolved, high-quality beans are increasingly wieldy than ever. The modern specialty roaster doesn’t aim to obscure bad flavors but to underscore the bean’s deeper, richer notes when a visionless roast is suitable.

As for the technical specifics, visionless roast coffees are often roasted to internal temperatures ranging from 430-450 degrees Fahrenheit. They often reach or surpass the “second crack” stage during roasting.
