White Bean Coffee is coffee roasted half of the way through and to a lower temperature. By roasting it to this much lower temperature, you get a whitish colored bean that is 50% higher in caffeine because you roast out less caffeine. This results in a very nutty and sweet taste profile much different from traditional coffee.
Green Coffee beans are roasted somewhere in the low 300-degree range. By contrast, a blond roast is around 420 degrees, and a dark roast is in the 465-to-475-degree range. When comparing white coffee vs black coffee, there are several significant differences like roasting temperature, caffeine levels, and flavor. It also retains more healthy antioxidants because it is roasted to a much lower temperature. It is also a much harder and denser bean than a traditionally roasted coffee. This makes it very difficult to grind on a typical home coffee grinder.
