Tag: Brew variables

According to a 2018 study from the University of Newcastle, French press coffee extracted slightly more caffeine per liter than pour over in controlled tests. However, the real answer to what has more caffeine, French press or pour over, is far more complex and depends on multiple brewing variables.

According to USDA data, a standard single shot of espresso contains roughly 64mg of caffeine. Based on this average, the approximate total for how many mg are in 4 shots of espresso is 256mg, though this figure is not static due to numerous variables.

According to the U.S. Department of Agriculture, a single 1-ounce shot of espresso contains about 63 milligrams of caffeine, meaning the standard amount for 2 shots of espresso is approximately 126 milligrams. However, this is just an average, and the actual caffeine content can vary widely depending on the beans, roast, and brewing process. This variation is why understanding the factors at play is so crucial for any coffee enthusiast aiming for a consistent brew.
