The finer the grind, the greater the surface area of the grounds, which means a faster release of both caffeine and flavor. Also, the higher the water temperature, the more caffeine is extracted. Generally, the lengthier the brewing time, the higher the caffeine content. Note: The amount of caffeine lost during longer roasting is fairly nominal, so this doesn’t have as significant an impact as the other factors. Dark roast coffee has the least caffeine, while gold roast and light roast have the most caffeine per serving.

Compared to the baseline number of around 100 mg, that’s nearly triple the amount of caffeine in a regular cup of coffee!
