This bold and energizing drink combines a full cup of brewed coffee with a shot of espresso, resulting in a powerful fusion that delivers maximum energy with minimal effort.

What Is Red Eye Coffee?
Red Eye Coffee is a coffee drink that blends 8 ounces (240 ml) of brewed coffee with 1 shot (30 ml) of espresso. It’s named after “red-eye flights,” which are overnight flights that arrive early in the morning — often taken by people who need to stay alert with little to no sleep.
The goal of Red Eye Coffee is the same: to help you stay awake and focused when you need it the most. With its intense flavor and high caffeine content, it’s a favorite among students, professionals, and coffee lovers who crave strong, straightforward energy without fancy extras.
Why Red Eye Coffee Is So Popular
✔ Maximum Caffeine – Combining two types of coffee delivers one of the strongest beverages you can make at home.
✔ Bold, Rich Flavor – Espresso adds depth, intensity, and complexity to the smooth base of drip coffee.
✔ Simple Ingredients – Only brewed coffee and espresso. No milk, sugar, or syrups required (unless you want them).
✔ Customizable Strength – You can add more espresso shots to adjust the power level to your preference.
What You Need to Make Red Eye Coffee
Ingredients:
- 8 oz (240 ml) of freshly brewed coffee
- 1 shot (1 oz or 30 ml) of espresso
Equipment:
- Coffee brewing method: drip coffee maker, French press, or pour-over
- Espresso maker: espresso machine, Moka pot, or AeroPress
- Large mug or cup for serving
Pro Tip: Always use freshly ground, high-quality coffee beans. This ensures a richer flavor and better overall result.
Step-by-Step Guide: How to Make Red Eye Coffee
Step 1: Brew the Coffee
Choose a method that suits your taste and convenience:
- Drip Coffee Maker – Easy and reliable for everyday use.
- French Press – Produces a rich, full-bodied brew. Steep for 4 minutes before plunging.
- Pour-Over (e.g., Chemex, Hario V60) – Offers clarity and balance with greater control over strength.
Use a medium or dark roast for a deeper flavor, and brew a full cup (8 oz / 240 ml).
Tip: For a stronger base, use a coffee-to-water ratio of 1:14 or even 1:12 depending on your preference.
Step 2: Make the Espresso Shot
You can extract your espresso using different tools:
- Espresso Machine – Delivers the most authentic result.
- Moka Pot – Produces a strong, espresso-style coffee.
- AeroPress – Use fine grounds and a high-pressure plunge for espresso-like intensity.
Pull one standard shot (30 ml) or adjust to your taste.
Tip: Use a dark roast espresso to get that bold, punchy flavor that stands up to the brewed coffee.
Step 3: Combine Coffee and Espresso
- Pour the brewed coffee into a large mug.
- Gently add the espresso shot on top.
- Stir it if you want a uniform blend, or leave it layered for a visual treat.
You can also try different variations based on your caffeine tolerance:
| Drink Name | Recipe | Approx. Caffeine |
|---|---|---|
| Red Eye | 1 shot espresso + 8 oz coffee | ~158 mg |
| Black Eye | 2 shots espresso + 8 oz coffee | ~221 mg |
| Dead Eye | 3 shots espresso + 8 oz coffee | ~284 mg |
Warning: Dead Eye is not for the faint of heart. Be cautious with high caffeine intake!
Step 4: Serve and Savor
Drink it hot and fresh for the best flavor and maximum energy. It pairs perfectly with:
- A light breakfast (toast, eggs, or fruit)
- A pastry or muffin
- A protein-rich snack before workouts or long workdays

Expert Tips for the Best Red Eye Coffee Experience
1. Use Fresh, High-Quality Beans
Freshly roasted and ground beans make a big difference in flavor and aroma.
2. Adjust Your Strength
Tailor the ratio to your energy needs. Red Eye for moderate caffeine, Black Eye for heavy-duty, Dead Eye for extreme focus.
3. Experiment With Roasts
- Light roast – Brighter flavor, more acidity.
- Medium roast – Balanced and smooth.
- Dark roast – Bold, chocolaty, and intense.
4. Try Different Brewing Methods
A pour-over Red Eye will taste different than one made with a French press. Play around until you find your favorite combo.
5. Drink Responsibly
This is a high-caffeine beverage, so be mindful of how your body reacts, especially if you’re drinking more than one cup a day.
When to Drink Red Eye Coffee
This drink is perfect for:
- Early mornings when regular coffee isn’t enough.
- Long study sessions for enhanced concentration.
- Night shifts when staying alert is critical.
- Before workouts for a powerful pre-exercise energy boost.
- During road trips to maintain focus behind the wheel.
Is Red Eye Coffee Safe?
Red Eye Coffee is generally safe for healthy adults in moderation. However, overconsumption of caffeine can lead to:
- Insomnia
- Jitters
- Increased heart rate
- Digestive discomfort
The FDA recommends up to 400 mg of caffeine per day, so even a Dead Eye still falls within this limit — but be cautious if you’re drinking other caffeinated beverages as well.
Consult a doctor if you have any health conditions or are sensitive to caffeine.
