Some mornings require a little more caffeine to get you through the day. Luckily, you can get an extra caffeine boost with red eye and black eye coffees.
Both types of coffee orders have extra caffeine, but they vary in their intensity. A red eye coffee, named after red eye flights, adds a shot of espresso for an extra kick.
Black eye coffee offers even more caffeine. A black eye coffee has two shots of espresso added to regular drip coffee and earns its name due to its dark color from the extra shots.
Both are significantly higher in caffeine than regular coffee, which has about 10 to 100 milligrams. However, the caffeine level isn’t the only difference between the two drinks.
