According to the USDA, a standard 1-ounce (30 ml) shot of espresso contains approximately 63 milligrams of caffeine. However, this is just an average, as the actual amount of caffeine in a shot of espresso can vary significantly based on several factors, including the type of coffee bean and the preparation method.

According to the National Coffee Association, over 60% of Americans drink coffee daily, yet few realize how sensitive the flavor is to change. There are many reasons why coffee suddenly tastes different, and the culprit isn't always the beans. This sudden shift in taste can be frustrating, but pinpointing the cause is key to reclaiming your perfect cup.

The caffeine content in cold brew can vary dramatically, with studies showing potential ranges from 100 to over 300 milligrams in smaller 12-16 oz servings. So, how many mg of caffeine are in 24 oz of cold brew? A definitive answer is elusive due to many variables, but a rough estimate based on industry examples suggests it could contain anywhere from 260 to upwards of 340 mg, making it a very potent drink.

According to coffee experts, grind size is one of the most critical factors influencing extraction and flavor. But do smaller coffee grounds make stronger coffee, or is there more to the story? While a finer grind can increase extraction speed, it's a balancing act that, if done incorrectly, can lead to a bitter, unpleasant brew.

While drip coffee typically contains between 65–120mg of caffeine per 8-ounce cup, a cup of pour over coffee can range from 90 to 160mg, or even higher, depending on preparation. Unlike automated machines, the manual control of the pour over method offers significant influence over the final caffeine level.
