Deep roasted beans for coffee Note: caffeine is higher than light roasted beans
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-roasted beans is lower than that of shallow-roasted beans, but the fact may be just the opposite. due to 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. This is important.
