Last updated 2026-09-29 — Because of the high rate of dehydration and weight loss of deep roasted beans, it is necessary to brew coffee with more coffee beans, resulting in drinking more caffeine, so the caffeine of deep roasted beans is higher than that of shallow roasted beans, which is very important. The melting point of caffeine is as high as 237 degrees Celsius, so the roasted caffeine is almost completely retained and dissolved in the cup. People often mistakenly think that the caffeine of deep-baked beans is lower than that of shallow-baked beans, but it may be just right.

It is important to recognize that dark roasted beans have higher caffeine than light roasted beans because they have a higher dehydration loss rate and must be brewed with more coffee beans, resulting in more caffeine. Caffeine has a melting point of 237 degrees Celsius, so roasted caffeine remains almost intact and dissolves in the cup. It is often mistaken that dark roasted beans have lower caffeine than light roasted beans, but the opposite may be true. Because dark roasted beans have a high dehydration weight loss rate, more coffee beans must be brewed, resulting in more caffeine. Therefore, it is important to realize that dark roasted beans have higher caffeine than light roasted beans.
