How Much Coffee Grounds for 1 Gallon Cold Brew


Welcome to our comprehensive guide on how to make the perfect 1 gallon of cold brew coffee! In this article, we will explain what cold brew coffee is, why it has gained popularity, and most importantly, how much coffee grounds you should use to achieve a delicious and refreshing cold brew. So, let’s dive in and discover the secret to making a fantastic cold brew coffee at home!

What is Cold Brew Coffee?

Cold brew coffee is a brewing method that involves steeping coffee grounds in cold water for an extended period, usually overnight. This slow and gentle extraction process results in a smooth, less acidic, and less bitter cup of coffee compared to traditional hot brewing methods.

The cold water extracts the flavors and caffeine from the coffee grounds, resulting in a concentrate that can be diluted with water or milk to your desired strength. Cold brew coffee is typically served over ice and is a popular choice for those who enjoy a refreshing and subtly flavored coffee beverage.

Why Cold Brew Coffee?

Cold brew coffee has gained immense popularity among coffee lovers for several reasons:

  1. Low Acidity: The extended steeping time significantly reduces the acidity of the coffee, making it easier on the stomach and teeth.
  2. Smooth Flavor Profile: Cold brew coffee has a smooth and mellow flavor with subtle hints of chocolate, caramel, and nuttiness.
  3. Less Bitterness: The cold water extraction process reduces the bitterness, resulting in a more enjoyable and less astringent coffee experience.
  4. Convenience: Once you’ve brewed a batch of cold brew coffee concentrate, it can be stored in the refrigerator for up to two weeks, allowing you to enjoy a quick and hassle-free cup of coffee whenever you desire.

How Much Coffee Grounds for 1 Gallon Cold Brew?

Now, let’s get down to the most crucial part – determining the right amount of coffee grounds for your 1 gallon cold brew. The general consensus among coffee enthusiasts is to use a coffee-to-water ratio of 1:8 to 1:10. This means for every 1 unit of coffee, you’ll need 8 to 10 units of water.

Since we’re making 1 gallon of cold brew, which is equivalent to 128 fluid ounces or roughly 3.8 liters, we’ll need to do some calculations. Let’s assume we want to go with a ratio of 1:8:


To find out how much coffee grounds we need, we can divide the total water volume (128 fluid ounces) by the ratio (8): 128 / 8 = 16. So, we’ll need 16 fluid ounces of coffee grounds for 1 gallon of cold brew.

Recommended Measurement:

It’s important to note that using fluid ounces for coffee grounds can be confusing due to their varying densities. To simplify the process, we highly recommend using a kitchen scale to measure your coffee grounds accurately.

For 1 gallon of cold brew, we recommend using 113 grams (4 ounces) of coarsely ground coffee. This measurement ensures a well-balanced and flavorful cold brew without being too strong or too weak.

Remember, this measurement can be adjusted based on your personal taste preferences. If you prefer a stronger cold brew, you can increase the coffee grounds slightly, whereas for a milder flavor, reduce the amount accordingly.

Advantages of Using the Recommended Measurements

By following the recommended measurements, you can enjoy the following advantages:

  • Consistency: Using a consistent coffee-to-water ratio ensures that you achieve consistent results every time you make cold brew coffee.
  • Optimal Extraction: Using the right amount of coffee grounds allows for optimal extraction of flavors without overpowering or diluting the coffee.
  • Balance: The recommended measurements strike the perfect balance between strength and flavor, resulting in a delightful cold brew experience.

Tips for Making the Best 1 Gallon Cold Brew

To enhance your cold brew coffee-making skills, here are some valuable tips:

1. Quality Coffee Beans:

Start with high-quality coffee beans as they greatly impact the flavor and overall quality of your cold brew coffee. Select beans that are freshly roasted and suited to your taste preferences.

2. Coarsely Ground Coffee:

For cold brew, it’s crucial to use coarsely ground coffee to prevent over-extraction and murky coffee. The coarse grind allows for a slow and steady extraction process, resulting in a smoother cup.

3. Use Filtered Water:

Since water makes up a significant portion of cold brew, it’s important to use high-quality and filtered water to avoid any unpleasant flavors or impurities that can affect the taste of your coffee.

4. Steeping Time:

An average steeping time for cold brew is usually between 12 to 24 hours, depending on your personal preference. Experiment with different steeping times to find your desired strength and flavor profile.

5. Strain the Brewed Coffee:

After the steeping process, strain the cold brew concentrate using a fine-mesh sieve or a cheesecloth to remove any sediment and ensure a clean and smooth final product.

Difference between Cold Brew and Iced Coffee

Cold Brew Iced Coffee
Made by steeping coffee grounds in cold water for an extended time. Made by brewing hot coffee and then pouring it over ice.
Low acidity and smooth flavor. Retains the acidity of hot brewed coffee.
Takes longer to prepare but can be stored in the refrigerator for up to two weeks. Prepared quickly but needs to be consumed immediately to avoid dilution.


In conclusion, making the perfect 1 gallon of cold brew coffee requires a balance between the amount of coffee grounds and water. By following the recommended measurements of using 113 grams (4 ounces) of coffee grounds to 1 gallon of water, you can enjoy a consistent, flavorful, and refreshing cold brew coffee. Remember to use high-quality coffee beans, coarsely grind them, and experiment with steeping times to find your preferred taste. With these tips and guidelines, you’ll be able to create a delightful cold brew coffee experience in the comfort of your own home. Cheers!

FAQs (Frequently Asked Questions)

1. How long should I steep the coffee grounds for cold brew?

When making cold brew coffee, it is recommended to steep the coffee grounds for at least 12 hours. This allows enough time for the water to fully extract the flavors and oils from the coffee beans, resulting in a smooth and rich brew. However, some people prefer to steep it for longer, up to 24 hours, for a stronger coffee flavor. Experiment with different steeping times to find your preferred taste.

2. Can I use any type of coffee grounds for cold brew?

Yes, you can use any type of coffee grounds for cold brew. However, many coffee enthusiasts recommend using a coarsely ground coffee as it helps to prevent over-extraction and bitterness in the final brew. Coarse grounds allow for a slower extraction process, resulting in a smoother and less acidic cold brew. Nevertheless, feel free to experiment with different coffee grounds to find the flavor profile that suits your preferences best.

3. Can I reuse the coffee grounds for a second batch of cold brew?

While it is possible to reuse coffee grounds for a second batch of cold brew, the resulting brew will be weaker in flavor compared to the first batch. This is because cold brewing extracts the flavors more gradually than hot brewing methods, and most of the desirable compounds are already extracted in the first steeping. If you decide to reuse the grounds, keep in mind that you might need to steep them for a longer time to extract enough flavor for a satisfying brew.

4. How should I store the cold brew after brewing?

After brewing your cold brew coffee, it is advisable to transfer it into a sealed container and store it in the refrigerator. This helps to maintain its freshness and prevent any bacterial growth. Cold brew can generally remain fresh for up to two weeks when stored properly. If you prefer a longer shelf life, you can also consider freezing the cold brew in ice cube trays and later defrosting the cubes as needed.

5. Can I dilute the cold brew with water or milk?

Absolutely! Cold brew coffee can be diluted with water or milk according to your personal preference. It is a highly customizable beverage, allowing you to adjust the strength and flavor to suit your taste buds. Many people prefer diluting cold brew with equal parts water or serving it over ice for a refreshing summer beverage. Additionally, you can add milk, cream, or sweeteners to create a creamy and flavorsome iced coffee concoction.
