How to Make a Red Eye Coffee: Espresso-Infused Drip Brew
Contents
A red eye coffee combines brewed drip coffee with a shot of espresso for an extra caffeine boost. To make one: brew a standard 8oz cup of drip coffee, then add one (single or double) shot of freshly pulled espresso. Stir gently and serve. Variations include the “black eye” (2 shots) and “dead eye” (3 shots).
What You’ll Need
- Equipment:
- Drip coffee maker, French press, or pour-over setup
- Espresso machine or Moka pot
- Coffee grinder (optional, for whole beans)
- Coffee:
- 15–20g (2–3 tbsp) drip coffee grounds (medium grind)
- 7–14g (for single/double shot) espresso beans (fine grind)
- Water ratio:
- Drip: 1:15–1:17 coffee-to-water (e.g., 20g coffee to 300ml water)
- Espresso: 1:2 coffee-to-water (e.g., 18g coffee yields 36g espresso)
Step-by-Step
- Brew drip coffee: Use your preferred method (drip machine, French press, etc.). Aim for 8oz (240ml) of brewed coffee.
- Pull espresso shot: Grind espresso beans finely and extract 1 shot (30–40ml) using an espresso machine or Moka pot.
- Combine: Pour the fresh espresso directly into the brewed coffee.
- Stir: Mix gently to blend flavors evenly.
- Adjust: Add milk, sugar, or syrup if desired.
Tips
- Use freshly roasted beans for both drip and espresso to avoid bitterness.
- If using a Moka pot, preheat water to reduce extraction time and bitterness.
Common Mistakes
- Over-extraction: Using too fine a grind or long brew times can make the coffee bitter.
- Stale beans: Old coffee loses flavor and complexity.
- Inconsistent ratios: Stick to standard measurements for balanced strength.
Variations
- Black eye: Add 2 espresso shots instead of 1.
- Dead eye: Add 3 espresso shots (over 300mg caffeine).
- Iced red eye: Chill the drip coffee before adding espresso over ice.
FAQ
How much caffeine is in a red eye?
Approximately 200–250mg (95mg from drip + 63mg per espresso shot).
Can I use instant espresso?
Yes, but fresh espresso delivers better flavor. Dissolve 1 tsp instant espresso in 30ml hot water.
What’s the difference between a red eye and an Americano?
An Americano is espresso diluted with hot water; a red eye is drip coffee enhanced with espresso.
How do I order a red eye at a café?
Ask for “a drip coffee with a shot of espresso” or the café’s “red eye” if listed.
