How to Make a Cold Brew Mocha at Home: A Step-by-Step Guide

I've always been a fan of a good cold brew mocha. It's the perfect blend of rich coffee and chocolatey goodness, ideal for those warm summer days or when you're just craving something deliciously cool. But why spend a fortune at a coffee shop when you can easily make it at home?

Making cold brew mocha at home isn't just cost-effective; it's also incredibly satisfying. You get to tweak the recipe to your liking, making it as chocolatey or as strong as you prefer. Plus, it's easier than you might think. Let's dive into how you can whip up this delightful beverage in your own kitchen.

Choosing the Right Coffee Beans

When I embarked on my cold brew mocha journey, I quickly learned that not all coffee beans are created equal. The choice of beans can dramatically affect the flavour of your cold brew. Dark roast beans are my go-to for a rich, robust flavour.

Firstly, let's talk about origin. Single-origin beans from places like Ethiopia or Colombia can add a unique twist to your cold brew mocha. Each region brings its own distinct flavour profile. For a chocolatey note, I often lean towards beans from Central and South America.

Bean freshness is another critical factor. I always look for beans that were roasted no more than a few weeks ago. This ensures that the coffee's natural oils, which contribute to its flavour, are still intact.

  1. Grind the beans coarsely. A coarse grind is ideal for cold brew as it allows for optimal extraction without over-extracting, which can lead to bitterness.
  2. Measure your coffee. I typically use a 1:8 coffee to water ratio for a strong brew that blends perfectly with the chocolatey components of the mocha.
  3. Mix coffee with cold water. In a large jar, combine the coffee grounds and cold water. Stir gently to make sure all the grounds are wet.
  4. Steep overnight. Cover and let it steep in the fridge for about 12-15 hours. This slow extraction process is what gives cold brew its smooth, rich flavour.
  5. Strain the coffee. Use a fine mesh sieve or a cheesecloth to filter out the coffee grounds.
  6. Mix with your chocolate syrup and milk. Now for my favourite part - blending the cold brew with chocolate syrup and milk to create the perfect cold brew mocha. Adjust the ratios according to your taste.

Selecting the Perfect Cocoa Powder

When crafting a cold brew mocha, one of the most critical elements I've found is selecting the right cocoa powder. This choice can profoundly affect the overall taste and richness of your drink. After years of experimenting with various types, I've learned a couple of things that might help you nail down the perfect cocoa powder for your mocha.

First off, it's essential to look for unsweetened cocoa powder. This allows you to control the sweetness level of your mocha, ensuring it perfectly suits your taste. There are two main types of unsweetened cocoa powder: natural and Dutch-processed. Natural cocoa powder is acidic and sharp, with a lighter color and a fruity undertone, which can add a unique twist to your cold brew mocha. On the other hand, Dutch-processed cocoa powder is treated with an alkalizing agent, making it darker, smoother, and more mellow in flavor. For a rich and smooth cold brew mocha, I personally lean towards Dutch-processed cocoa powder.

Another thing to consider is the fat content. Higher fat cocoa powders, though harder to find, can offer a more luxurious mouthfeel and intensity of flavor. They blend beautifully into the cold brew, creating a decadent mocha experience that's unparalleled by their lower fat counterparts.

Here's a simple, bullet-point guide on choosing your cocoa powder:

Remember, the perfect cold brew mocha is about personal preference, and exploring different cocoa powders is part of the fun. Each type brings its own unique character to your mocha, so don't be afraid to experiment until you find your perfect match.

Making Cold Brew Coffee

Before diving into the rich world of cold brew mocha, let's talk about the foundation - making cold brew coffee. I've found this process not only enjoyable but truly rewarding. Cold brew is smoother and less acidic than its hot counterpart, making it the perfect base for our mocha.

I start with coarse-ground coffee. This is crucial because finer grounds could result in a bitter and over-extracted brew. Typically, I use a ratio of 1:8, one part coffee to eight parts water. It's a forgiving recipe, allowing you to adjust according to your taste preference.

Here's how I make it:

  1. Measure your coarse-ground coffee.
  2. Combine the coffee with cold, filtered water in a large jar or a French press. I prefer using filtered water as it ensures there are no unwanted tastes in my brew.
  3. Stir gently to make sure all the grounds are wet.
  4. Cover and let it steep at room temperature. This part is essential. I leave it for about 12 to 24 hours. The longer you steep, the stronger your cold brew.
  5. Strain the mixture using a fine mesh sieve and a coffee filter to get rid of all the grounds. If you're using a French press, just press down slowly and pour.

And voila, you've got yourself a cold brew concentrate that's bold, smooth, and ready to be transformed into an amazing cold brew mocha. Remember, this concentrate is quite strong, so it's perfect for diluting with other ingredients without losing its coffee essence.

Feel free to experiment with the steeping time and coffee-to-water ratios. It's the personal touches that make your cold brew unique. For those looking for an ultra-convenient cold brew method, various cold brew coffee makers are available in the market, designed to streamline the process. However, I've found that making it manually adds a certain charm and allows for greater control over the final product.

Creating the Mocha Mix

Once you've got your cold brew concentrate ready, it's time to whip up the mocha mix. I absolutely adore how simple yet utterly transformative this part is. By combining chocolate with coffee, you elevate a regular cold brew into something spectacularly indulgent. Let me guide you through the effortless steps to create the perfect mocha mix.

Ingredients You'll Need:

Steps to creating the Mocha Mix:

  1. Start with the Chocolate Base:
  1. Sweeten to Taste:
  1. Mix with Your Cold Brew:
  1. Add Milk and a Dash of Vanilla:
  1. Ice, Stir, and Serve:

Experimenting with the proportions of the ingredients is the key to tailoring the mocha mix to your taste. Some like it chocolatier, while others may prefer it milkier. There's no right or wrong here, just what delights your palate. By following these simple steps, achieving a café-quality cold brew mocha at home couldn't be easier.

Mixing it All Together

Now that you've got your cold brew concentrate ready and your mocha mix perfected, it's time to combine them into a delicious cold brew mocha that'll rival any café creation. Here's how I do it, step by step:

  1. Measure the Ingredients: I start by measuring out my ingredients. You'll want to have your cold brew concentrate and mocha mix at hand. For me, the perfect ratio is about 1 part coffee concentrate to 1 part mocha mix, but feel free to tweak this based on your preference.
  2. Combine the Concentrate and Mocha Mix: In a large pitcher or jug, I pour the cold brew concentrate and then add the mocha mix. It’s important to add them gradually and taste as you go, ensuring the balance is just right for your taste buds.
  3. Stir Well: This might seem obvious, but stirring is key. I use a long spoon to stir the mixture thoroughly, ensuring the mocha mix is completely dissolved in the cold brew. No one likes a clumpy or uneven mocha!
  4. Add Ice: Next, I fill my glass with ice. I prefer large cubes that don’t melt too quickly and dilute the flavours.
  5. Pour and Customize: I then pour the mixture over the ice-filled glass. At this point, you can add extra milk, a dash of vanilla extract, or even whipped cream on top for that extra indulgence.
  6. Sweeten to Taste: If it’s not sweet enough for you, feel free to add more sugar or your preferred sweetener. Remember, the beauty of making your cold brew mocha at home is that you can tailor it exactly to how you like it.

And there you have it! With these simple steps, you’re well on your way to enjoying a refreshing and personalised cold brew mocha. Don’t forget the importance of experimentation - playing with the proportions of the ingredients can lead to finding your perfect blend.


Crafting the perfect cold brew mocha at home is simpler than it might seem. By following the steps I've shared, you're well on your way to enjoying a café-quality beverage without stepping out the door. Remember, the key lies in finding the right balance of ingredients to suit your taste. Don't be afraid to experiment with different proportions or add-ins like milk or vanilla extract.
