Last Updated: 2025/08/21, There are several aspects of caffeine content, one is bean seed, the second is baking degree, the third is the weight of coffee powder, and the fourth is extraction rate. As mentioned above, if the same weight varieties of coffee raw beans, due to more water loss in deep baking, the resulting ripe beans are lighter. Therefore, the same cooked beans in the middle is equivalent to using more raw beans to get. So there will be more artificial caffeine, but it will also be affected by grinding degree and water.

There are several aspects of caffeine content, one is bean seed, two is roasting degree, three is coffee powder weight, four is extraction rate. As mentioned above, if the same weight varieties of coffee beans, due to deep roasting water loss more, the resulting ripe beans are lighter. Therefore, the same middle cooked beans equivalent to more raw beans can be obtained. Therefore, there will be more artificial caffeine, but it will also be affected by grinding degree, water temperature, production equipment, etc.! The degree of roasting does not affect the amount of caffeine in coffee beans. This is because caffeine has a high boiling point. This does not mean, however, that the degree of roasting does not affect caffeine extraction. It is well known that the caffeine in a cup of coffee is directly proportional to the number of beans needed to make it. That is, the more coffee beans used in this cup, the higher the caffeine content, and vice versa. For the same powder-to-water ratio per cup, reroasted coffee beans have a higher rate of weight loss, so it takes more beans to make a cup of reroasted coffee than a cup of lightly roasted coffee. In addition, the extraction rate of reroasted coffee beans is high. So the mainstream view of extraction is that a cup of heavy roast coffee has more caffeine than a light roast.
