    There's so much to know and learn about the world of coffee. One tiny peek into this world is through homemade cold brew coffee.

    Think of this recipe as your starter's guide to cold brewed coffee. Even if you're new to drinking coffee or making it at home, this recipe will teach you all the basics you'll need to know.

    The expensive cold brew you drink from Starbucks isn't as much of a mystery as you may think. With minimal ingredients and tools, you'll be sipping on some delicious iced coffee that you can transform into an endless amount of coffee drinks.

    If you're a coffee expert, you may be wondering why this recipe is labeled as espresso. Technically, espresso is a coffee extraction process where hot water runs through finely ground coffee. However, many people associate espresso with a richly flavored dark roasted bean, which is why I've labeled this recipe as espresso cold brew.

    What You'll Learn In This Recipe

    You'll learn a lot of tips and tricks, as well as some science, including:

    • All of the factors that contribute to the taste of your espresso cold brew. Plus, how you can experiment to create a cold coffee you'll love.
    • The reason so many people love cold brewed coffee (hint: it tastes very different than hot coffee).
    • The best type of coffee beans to use for cold espresso.

    Ingredients You Need

    water and ground coffee beans in measuring cups.

    All you'll need for this recipe is:

    • Coarsely ground dark roasted coffee beans: You'll want a dark roasted coffee bean. For the best tasting cold brew, make sure the beans are freshly ground to a coarse texture.
    • Cold water: Feel free to use whatever water you have on hand. Some experts say filtered water is best. However, I have had great success with tap water. Feel free to experiment and see what you like best!

    How To Make This Recipe

    You may be shocked at how easy it is to make a strong cold brew concentrate at home. This recipe is even better than the store-bought brands like Stok and Cameleon.

    mason jar with water and coffee grounds.

    Start out by adding 1 cup of coarsely ground coffee beans to a 32 ounce (1 liter) glass jar along with 3 cups of cool water. Make sure all of the grounds are completely covered by the water.

    Then, screw on the lid and allow the coffee to brew in the fridge for 12 - 18 hours. Once your brew reaches 12 hours, you can test the taste every hour or so until you've reached your preferred flavor notes.

    I personally leave my coffee to brew for the full 18 hours.

    After the coffee has finished brewing, it's time to strain out the coffee grinds. I love this method because there is no machine or fancy equipment required.

    Pour the brewed coffee into the coffee filter and allow it to slowly strain in a bowl. You can then discard the coffee grounds in the trash can (not down the garbage disposal).

    Finally, transfer the coffee to a reusable glass bottle and store it in the refrigerator for up to 7 - 10 days. You can mix the cold brew with ice, water, milk, cream, half and half, or simple syrup to dilute the concentrate.

    Factors That Effect The Taste

    There's definitely a reason so many people love cold brew. The smooth and somewhat sweet taste is unmatched compared to a cup of hot coffee. Cold brewing gives the coffee a less bitter and acidic taste compared to a traditionally brewed hot cup.

    If you love cold brew and are interested in crafting your perfect brew, here are 4 factors that will affect the final taste:

    Type of Roast

    One huge factor in the taste of your cold brew is how the coffee bean was roasted. There are light, medium, and dark roasts.

    Some people prefer light roasts, while others (especially espresso lovers) like dark roasts. However, you can experiment to see which type of roast you most prefer.

    If you're an espresso lover, you probably prefer a dark roasted bean, like we use in this recipe. Remember, technically espresso isn't a type of roast. It's a coffee extraction process where hot water runs through finely ground coffee.

    You can also use a flavored coffee bean, like in this salted caramel recipe.

    Grind Size

    A coarsely ground coffee vs. a finely ground coffee will result in a very different taste in your cold brew.

    With a fine grind, the coffee is more likely to experience over-extraction (when too many soluble flavors are removed from the coffee resulting in undesirable tastes). Plus, it can be difficult to strain the fine ground coffee without getting graininess in the final concentrate.

    A coarse grind is almost always recommended!

    Temperature of Water

    There are two common methods for brewing cold brew - on the counter at room temperature or in the refrigerator. Obviously, each of these methods uses different temperatures of water.

    The main thing you need to keep in mind is that cold water extracts the grounds slower than room temperature water. Generally, you'll expect a refrigerated brew to need a few additional hours to brew compared to room temperature ones.

    After watching many videos on this topic, I believe the temperature of the water is a very personal preference. Try both and see which one you'd prefer!

    Length of Brew

    The goal of any brewing process is to extract the most flavor without worrying about over-extraction. I've found that the ideal length of brew is about 12 - 18 hours in the refrigerator. Remember, don't allow the coffee to brew too long or it will have a bitter taste.

    Recipe Frequently Asked Questions

    What can you do with cold brew?

    There are an endless amount of delicious drinks you can make with cold brew coffee. Try out my sweet cream cold foam recipe or add in a splash of vanilla coffee syrup. If you're feeling spicy, you could even try making an espresso martini!

    What's the best type of coffee beans to buy?

    It's best to buy freshly ground coffee beans. Even if you don't have a coffee grinder at home, many grocery stores will have a grinder in the coffee section. Fresher beans are going to give you a more vibrant cold brew.

    Which types of coffee beans are considered espresso?

    Most coffee beans are Arabica or Robusta, including espresso beans. Espresso is traditionally roasted longer and darker than other types of coffee beans. Although technically espresso isn't a type of roast (it's a coffee extraction method) many grocery stores will label dark roasted beans as espresso.

    I thought espresso is supposed to be finely ground. Why are we using coarsely ground espresso beans?

    Traditionally, yes, espresso beans are finely ground when you're brewing with hot water. However, cold espresso tastes best with coarsely ground beans because it takes on a less bitter flavor. Plus, it's easier to filter out the coarse grounds.

    Can I use finely ground espresso beans for cold brew?

    In a pinch, fine grounds will still work. However, the cold brew will taste more bitter if you use finely ground espresso beans.

    To avoid a bitter taste, check the taste of the cold brew every few hours to ensure over-extraction (when too many soluble flavors are removed from the coffee resulting in undesirable tastes) doesn't occur.

    What is a cold brew concentrate?

    A cold brew concentrate is simply a stronger brewed cold coffee that should be diluted down with ice, water, milk, or cream.

    How can I make a strong cold brew?

    The ratio of coffee beans to water will determine how strong your cold brew is. Typically, a concentrate (like this recipe) will result in a stronger cold brew. This recipe uses a ratio of 1 cup of coffee beans to 3 cups of water.

    Other (less strong) recipes may use more water, resulting in a more diluted final flavor.

    Ingredients
     
     

    • 1 cup coarsely ground dark roasted coffee beans
    • 3 cups cool water

    Instructions
     

    • Add ground coffee beans and water to a 32 ounce (1 liter) glass jar. Stir or shake to combine until all the grounds are fully covered with water. Screw on the glass jar lid.
    • Set glass jar in the refrigerator to steep for 12 - 18 hours.
    • Place a mesh strainer lined with a coffee filter over a medium-sized bowl. Pour the brewed coffee into the coffee filter and allow to slowly strain. This may take up to 15 minutes. Discard the coffee grounds in the trash can (not down a garbage disposal).

    • Serve the cold brew with ice, water, simple syrup, milk, or cream to dilute the concentrate.

    Notes

    If you're looking for a certain flavor profile from the cold brew espresso, once you hit the 12 hour mark, periodically check the taste. Allow the coffee to steep for more or less time depending on personal taste preference.
    The ratio of coffee beans to water will determine how strong your cold brew is. If you'd prefer a less strong concentrate, dilute the coffee beans with additional water.

      I just made cold brew for the first time this weekend and it turned out perfectly! I had no idea it was so easy to make cold brew at home. I have been wasting so much buying the pre-made version at the store all for no reason.

      If my jar has a filter can I just use that and take it out after it’s reached it’s peak taste?

        Question for you, I only drink Espresso: White Coffee. Due to not being roasted it comes pre-ground. Could I still use these beans for cold brew, even though they are fine grind?

          Hi Roberta! You can definitely try a fine grind and see how it turns out. However, a fine grind is more likely to experience over-extraction, sometimes resulting in an undesirable taste. But try it out and see what you think and go from there! 😊

      Once you make the cold brew, would you just add one shot of the espresso concentrate with ice to drink? Or do you mix it with water etc?
      And should you add sugar etc to it once it’s ready or only when you drink it?

        Hey Shay! It's really all personal preference. Personally, I like to use about 1/3 cup of concentrate, some ice, simple syrup (about 1 teaspoon), and then top it off with milk. You can definitely water it down with additional water if it's too strong. I'd just play around with the ratios and taste as you go. As for the sugar, I prefer to add it in when I'm ready to drink it. I've personally never added the sugar or simple syrup to a large batch. However, I don't see why that wouldn't work if you wanted to try it.
