The Common Coffee Myth Way Too Many People Buy Into

Adding an extra scoop of coffee when brewing a pot won't give you more caffeine — only a more bitter flavor. For more caffeine, pay attention to the roast and adjust your brewing.

Darker coffee beans spend more time roasting, burning off more caffeine in the process. This means a fine light roast will give you more caffeine than a coarse dark roast.

If you're using a coffee brewer that offers different cup sizes, like the Nespresso Vertuo Pop+ or the Keurig K-Elite, brew two cups instead of using the larger cup option for more caffeine.

If you're brewing a big pot with a drip coffee maker like the 14-cup Mr. Coffee maker, grab the first cup, as most of the caffeine ends up on the top of the pot.

The ideal ratio to get the most caffeine from your coffee is one to two tablespoons of ground coffee for every six ounces of water. The ideal temperature is 199 degrees Fahrenheit.
