Let me tell you about Dirty Coffee. I discovered it last year when I was getting tired of my regular morning coffee.
What makes it so special? It’s this beautiful drink where hot espresso floats on top of cold milk, creating these amazing swirls. It looks fancy (perfect for Instagram!), but super easy to make at home.
The first time I tried making it, I messed up by pouring the espresso too fast. But after a few tries, I got it right.
What I love most about this drink is how you get both hot and cold in every sip. Plus, you can make it stronger or lighter depending on what you like. I’m excited to share my simple tips with you so you can make the perfect cup on your first try.

Quick Facts
Dirty Coffee is a layered drink where hot espresso is poured over cold milk in a clear glass. The name comes from the way the espresso creates dark, swirling patterns as it mixes with the white milk. It’s that simple – just two ingredients creating a beautiful effect. The drink originated in Japan and offers a unique experience where each sip combines both hot and cold temperatures.

Equipment Needed
- Espresso Machine: For pulling the perfect espresso shot (primary brewing method)
- Alternative: Manual espresso maker, French press, or Moka pot
- Coffee Grinder: For fresh-ground beans (burr grinder recommended for consistent grind size)
- Clear Glass: 5-8 oz capacity (essential for showing off the layered effect)
- Coffee Scale: For precise measurements

Ingredients
Base Recipe
- 18g coffee beans (light to medium roast)
- 90ml cold whole milk
- 30ml heavy cream (optional)
Alternative Ingredients
- Milk Options: Oat milk, almond milk, soy milk (note: plant-based alternatives may affect layering)
- Coffee Alternatives: Dark roast beans (for stronger flavor), decaf beans
- Cream Alternatives: Half-and-half, coconut cream, or skip entirely for a lighter version
How To Make
1. Start by mixing your cold milk and cream in a glass. If you’re using a 5-ounce glass, mix 90ml of cold milk with 30ml of cream. For a bigger 8-ounce glass, use 120ml of milk and 50ml of cream. Put this mixture in the freezer for a few minutes to get it really cold.
2. While your milk is chilling, grind your coffee beans. You’ll need 18 grams of beans, ground a bit finer than regular espresso. This will give you the best flavor. Press the grounds firmly with your tamper.
3. Get your cold glass ready. Take your milk mixture out of the freezer and pour it into the glass, leaving some room at the top for the espresso.
4. Now make your espresso shot. This should take between 30 to 50 seconds to pull. The slower extraction gives you better flavor.
5. Here’s the most important part: very slowly pour your hot espresso over the cold milk. Pour it gently so it creates nice layers. You’ll see the espresso make beautiful swirls in the milk – that’s exactly what you want.
Serve your Dirty Coffee right away, before the temperatures start to mix too much. Don’t stir it – the layers are part of what makes this drink special.
Pro Tips

Troubleshooting
