Red-eye coffee is high in caffeine

It was named after taking a late-night flight, also known as a “red-eye,” due to its high caffeine content, consisting of one cup of coffee and a shot of espresso. As someone who works late but likes to get up early, I often find myself ordering red-eye from my favorite coffee shop to give me the boost I need.

Keeping Coffee Drinkers Awake

Red-eye coffee has quickly become a favorite of the coffee-drinking community due to its high caffeine content. A high caffeine content means that this coffee is likely to perk up drinkers faster and for longer than a regular Americano or cup of drip coffee would.

A cup of red-eye has a total caffeine content of 160 g

Red-eye coffee contains roughly 160 grams of total caffeine. This is much more than a single shot of espresso containing 64 grams, a double shot of espresso containing 128 grams, or an individual cup of coffee that has 95 total grams of caffeine. This exceptionally high level of caffeine in just one simple beverage is what keeps coffee drinkers coming back for more.

Variations on Red-Eye Coffee

While some might think that Red-eye coffee refers to one specific type of beverage, there are actually a few different variations of this high-octane coffee. Some of these variations include different numbers of espresso shots, instant vs. ground coffee beans, and even dollops of milk or cream.

The Deep Taste of Red-Eye Coffee

The taste of Red-eye coffee is not sweet or light, but rather deep, dark, and hearty. The mixture overall has an earthy and slightly bitter taste to it, similar to that of a plain cup of black coffee or some extra dark chocolate. 

Red-eye coffee flavor is deep, dark, and hearty

While in a coffee beverage like an Americano, it is possible to taste the flavor of the espresso separately from the water it is mixed in, the coffee in the Red-eye mostly absorbs the espresso taste to make it almost unrecognizable. This may be why the Red-eye coffee is mostly enjoyed by those wanting an energy pick-me-up rather than a taste of espresso.
