Clarification – Cold Brew vs Iced Coffee

It’s important to note that cold brew coffee is not the same as iced coffee. While both are served cold, the brewing methods and resulting flavors are vastly different.

Iced coffee is made by brewing hot coffee and then pouring it over ice. This method can produce a somewhat diluted and bitter flavor due to the heat and quick brewing time.

In contrast, cold brew coffee is brewed using cold or room temperature water over a longer period of time, usually 12-24 hours. The result is a highly concentrated coffee extract that is then mixed with cold water or milk to create a smooth, less acidic, and sweeter flavor. Cold brew also contains up to twice as much caffeine as iced coffee due to the longer extraction process.

Both cold brew and iced coffee are delicious ways to enjoy coffee on a hot day. It’s important to understand the differences between them and choose the brewing method that best suits your taste preferences.

How to Make Cold Brew Coffee at Home?

Here are two easy recipes you can use to make delicious cold brew.

Home-Made Cold Brew Recipe #1

To make cold brew coffee at home, you will need the following ingredients and equipment:

  • 1 gallon of water
  • 1 pound of coarsely ground coffee beans
  • Mason jar or other container with a lid
  • Fine-mesh strainer or cheesecloth
  • Pitcher or bottle to store the cold brew concentrate


  1. Start by coarsely grinding your coffee beans. If you don’t have a coffee grinder, you can ask your local coffee shop to grind them for you.
  2. In a large mason jar or container with a lid, combine 1 pound of coarsely ground coffee with 1 gallon of water. Stir gently to ensure that all the coffee is wet.
  3. Cover the jar with a lid and let it sit at room temperature for at least 12 hours, or up to 24 hours. The longer you let it steep, the stronger and more concentrated the coffee will be.
  4. Once the steeping process is complete, strain the coffee through a fine-mesh strainer or cheesecloth into a pitcher or bottle. You may need to strain it multiple times to remove all the coffee grounds.
  5. The resulting liquid is your cold brew concentrate. You can serve it over ice or dilute it with water or milk to your desired strength. The concentrate can be stored in the refrigerator for up to 2 weeks.

Home-Made Cold Brew Recipe #2

  1. To make a gallon of brew, weigh out 8 ounces of your java beans. Adjust if needed.
  2. Now grind your beans up.
  3. Get all of your fresh grounds into a strainer bag and place the bag inside your glass jar.
  4. Now add a gallon of water to the jar.
  5. Place your jar in the refrigerator for 14 to 16 hours.
  6. Take the bag out of the jar and squeeze behind as much liquid as possible.

Your cold brew java is now ready for you to flavor however you want! Get creative and play around with a variety of tastes and temperatures.

Pour it into your travel mug and enjoy the cold drink on the way to your work or the beach!

Remember, making cold brew coffee is a slow and patient process, but the end result is worth it! Experiment with different brewing times, coffee-to-water ratios, and beans to find your perfect cup of cold brew.

Benefits of Cold Brew Coffee

Making cold brew coffee involves steeping the coffee grounds in water for at least 12 hours, then filtering the grounds out for a very concentrated essence. That is something radically different from the process of brewing coffee in the espresso machine.

This java essence is then diluted with water or milk and can be served in many different ways, both hot and cold. The cold-brewed is known for having a less acidic and more mellow taste than coffee from the office coffee maker.

If you’re getting cold brew pretty often in Starbucks or Dunkin Donuts, it will save you both money and time if you start making your own at home. No more need to stand in a queue or shell out your hard-earned money.

Not only is it much cheaper, but it’s also a lot more customizable because you can make it suit your tastes. You can experiment with different grounds and try to find your best roast. You can test different grounds-to-water ratios and try out other sweeteners. There are so many options to test!

You don’t have to be limited to only a handful of set options off a menu because you can make whatever you want yourself. It also means you know exactly what is going into your brain juice and that it is not watered down.

Here’s how to make a fresh batch in the comfort of your own home to have whenever you want. One batch of this can last you a couple of weeks, and depending on your needs, you can half or double the recipe as you would like. This recipe will be for 1 gallon.

What Do You Need To Make A Cold Brew?

Here are the things you will need, all of which you probably already have lying around.

  • First up, a container, preferably glass, that can hold 1 gallon of liquid. If you are halving or doubling this recipe, your container size with change accordingly. Mason jar is an excellent option for this.
  • Next, you will need a Burr grinder specifically because of the consistent grind it can give instead of a blade grinder.
  • You will also need a filter. You can use a strainer bag specifically designed for this purpose, or you can use a cheesecloth, a t-shirt, or anything else you can think of.
  • Lastly, of course, you need the beans. We will be using whole beans for the best taste and freshness, but you can also use pre-ground coffee if you’re in a hurry.

It’s worth noting that while a Burr grinder is recommended for the best results, it is not essential. You can still make a good cold brew with pre-ground coffee or by using a blade grinder, although the taste and quality may not be as consistent. Additionally, some cold brew recipes may call for additional flavorings such as spices, extracts, or syrups, depending on personal preference. These can be added during the steeping process.

This ensures that the grounds are not over-extracted and that the cold brew is full-bodied, smooth, and not overly acidic.

Once you have your coarsely ground coffee, you can steep it in cold water for an extended period. This will result in a smooth and flavorful cold brew that is perfect for sipping on a hot day.
