The method for making red eye coffee, sometimes referred to as black eye or dead eye, is a popular yet controversial approach to boosting concentration and energy during extended study sessions or situations where regular coffee falls short.

What is Red Eye Coffee and How It's Made 1

I’ve been intrigued by it and done some research, so here’s what I found:

  1. First, the recipe. Red eye coffee is essentially a cup of drip coffee with one or more shots of espresso mixed in. Caffeine crush aside, the taste is actually very interesting, since drip coffee and espresso are different drinks with their own separate taste profiles. Because of this, red eye coffee comes out with a stronger and bolder taste than even just a strong drip coffee.
  2. Second, the strength. Obviously, you will be drinking a cup of very, very strong coffee — especially if you decide to add a second or third shot.
  3. Third, the history. It’s a classic beverage that has been a part of American coffee culture for ages. Interestingly, it has been called a lot of different (and whimsical) names: sludge cup, oil spill, hammerhead, shot in the dark, stink eye, Wellard Coffee or turbo regular.
  4. I found the most arcane recipe for red eye coffee on Reddit: pour a hot shot of espresso over coffee cubes (ice cubes made from cold brew), then fill the cup up with cold brew and add another coffee cube or two.

How to Make Easy and Delicious Cold Brew Coffee

Cold brew coffee is something unlike what you have tasted. Because it’s cold brewed over a long period – 24 hours is best – the flavours haven’t been demolished by heat. You get all the nuances, all the goodness, and a good dose of caffeine, too.

  • 1 glass


  • Light to medium roast coffee
  • Nut milk bag
  • Plastic pitcher
  • Cold water and ice to taste


  • Grind the beans to coarse (or "french press") grind. If you prefer your coffee on the bitter side, go for medium.
  • Put the coffee in the nut milk bag.
  • Add distilled water (or tap water will do). Ratio is 4:1.
  • Steep in a nut milk bag for 12+ hours in the counter or in the fridge. For bitter coffee, leave it there for 18+ hours.
  • Remove the bag from the coffee and squeeze out the remaining liquid.
  • Dilute the coffee with cold water and ice cubes to taste (I prefer 1:1).
  • If you like, add sweeteners and/or your milk of choice. Or just enjoy it like that.
