In this guide, you’ll learn how to make an authentic Red Eye Coffee at home, including the best brewing methods, different variations, and tips for achieving the perfect balance between espresso and coffee.
What Is Red Eye Coffee?
A Red Eye is simply a cup of brewed coffee with a shot of espresso added. This drink is ideal for those who love strong, bold coffee and need an extra caffeine kick without sacrificing flavor.
✔ Stronger than regular coffee – The espresso shot increases the caffeine content and adds depth to the flavor.
✔ Smoother than pure espresso – The brewed coffee balances the intensity of the espresso.
✔ Customizable strength – You can adjust the number of espresso shots for a lighter or more intense drink.
✔ No milk or sugar required – Red Eye Coffee is typically enjoyed black, but you can add milk or sweeteners if preferred.
Red Eye Coffee vs. Other High-Caffeine Coffees
✔ Black Eye Coffee – Made with two shots of espresso added to brewed coffee.
✔ Dead Eye Coffee – A stronger version with three shots of espresso added to brewed coffee.
✔ Drip Coffee – Regular black coffee without espresso.
✔ Americano – Espresso diluted with hot water instead of brewed coffee.
Ingredients & Equipment for the Perfect Red Eye Coffee
✔ 8 oz (240ml) freshly brewed coffee (medium or dark roast for best flavor)
✔ 1 oz (30ml) freshly brewed espresso (single shot)
✔ Drip coffee maker, French press, or pour-over setup

The key to making a great Red Eye Coffee is using high-quality espresso and freshly brewed coffee, ensuring the flavors blend well.
Step-by-Step Guide to Making a Red Eye Coffee
Step 1: Brew Fresh Coffee
✔ Use medium or dark roast coffee beans for a bold flavor.
✔ Brew 8 oz (240ml) of coffee using your preferred method:
- Drip Coffee Maker – Produces a classic, smooth flavor.
- French Press – Creates a rich, full-bodied coffee.
- Pour-Over – Offers a cleaner, more refined taste.
✔ Tip: Make your coffee slightly stronger than usual to complement the espresso.
Step 2: Brew a Shot of Espresso
✔ Pull a single shot (1 oz or 30ml) of espresso using an espresso machine.
✔ If you don’t have an espresso machine, use:
- Moka Pot – Produces a strong, espresso-like coffee.
- AeroPress – Use fine grounds and a short brew time for concentrated coffee.
✔ Tip: For a stronger caffeine boost, use a double shot of espresso.
Step 3: Combine the Coffee and Espresso
✔ Pour the freshly brewed coffee into a large mug.
✔ Slowly add the shot of espresso on top.
✔ Stir gently to blend the flavors.
✔ Tip: If you prefer a layered look, pour the espresso slowly over the back of a spoon.
Step 4: Customize to Taste
✔ Red Eye Coffee is traditionally enjoyed black, but you can add:
- Milk or cream for a smoother taste.
- Sugar or honey for sweetness.
- Flavored syrups (vanilla, caramel, or hazelnut) for an extra twist.
