An Introduction to Cold Brew: Two Simple Methods for Making Cold Brew Coffee at Home

At Cold Blooded Caffeine, we believe that great coffee should be accessible to everyone, regardless of their brewing expertise or equipment. That's why we're excited to share two incredibly simple methods for making delicious cold brew coffee at home. Whether you're a busy professional looking for a quick morning fix or a coffee enthusiast who enjoys brewing in larger batches, we've got you covered. Let's dive into these easy techniques that will elevate your cold brew game.

Why Cold Brew?

Before we get into the methods, let's quickly touch on why cold brew has become so popular:

1) Smooth, Less Acidic Flavor: The cold extraction process results in a less acidic, smoother taste compared to hot brewed coffee.

2) Versatility: Cold brew can be enjoyed over ice, mixed with milk, or even heated up for a smooth hot coffee.

3) Convenience: Make a batch that lasts for days, saving you time in your morning routine.

4) Less Bitterness: The cold brewing process extracts less of the compounds that can make coffee taste bitter.

Now, let's explore our two foolproof methods for creating cold brew at home.

Method 1: Single-Serve Cold Brew Bags

This method is perfect for those who want a fresh, single serving of cold brew with minimal fuss and cleanup.

What You'll Need:

1.5 ounces of fresh ground coffee

Paper tea filters (search for them on Amazon)

A mason jar with a sealable lid

24 ounces of water

(Optional) Heat sealer or iron

Step 1: Prepare Your Cold Brew Pack

Place 1.5 ounces of freshly ground coffee into a paper tea filter. If you have a heat sealer, use it to seal the filter. Alternatively, you can use a standard iron to press and seal where the bag overlaps at the top.

Pro Tip: For the best flavor, use coffee ground specifically for cold brew. It should be coarser than regular drip coffee grounds.

Step 2: Combine Coffee and Water

Add 24 ounces of room temperature or cold water to your mason jar. Insert the sealed coffee pack into the water, ensuring it's fully submerged.

Step 3: Steep

Seal your mason jar and let it sit at room temperature for 18-24 hours. The longer you steep, the stronger your cold brew will be.

Step 4: Serve

After steeping, simply remove the coffee pack and discard it. Your cold brew is ready to serve over ice or store in the refrigerator for later enjoyment.

Benefits of This Method:

Perfect for individual servings

Minimal cleanup

Great for travel or small spaces

Consistent results every time

Method 2: Batch Cold Brew Concentrate

This method is ideal for those who enjoy larger quantities of cold brew or prefer to go through the brewing process less frequently.

What You'll Need:

12 ounces of coarsely ground coffee

A one-gallon pitcher

A filter basket and filter from a regular drip coffeemaker

Half gallon (64 ounces) of water

An additional pitcher for straining

Step 1: Combine Coffee and Water

Add 12 ounces of coarsely ground coffee to your one-gallon pitcher. Pour in half a gallon of room temperature or cold water. Stir thoroughly to ensure all the coffee grounds are wet.

Step 2: Steep

Cover the pitcher and let it sit at room temperature for 18-24 hours.

Step 3: Strain

After steeping, place your filter basket with a clean filter over another pitcher. Slowly pour the cold brew mixture through the filter. This process may take some time, so be patient and continue topping off as it drains through.

Step 4: Dilute and Serve

What you've made is a cold brew concentrate. Before serving, dilute it with water to taste. We recommend starting with a 1:1 ratio of concentrate to water.

Benefits of This Method:

Produces a larger quantity of cold brew

More economical for frequent cold brew drinkers

Creates a versatile concentrate that can be used in various recipes

Tips for Cold Brew Success:

Use Quality Coffee: The better your beans, the better your cold brew. 

Grind Matters: For both methods, a coarse grind is crucial. It allows for optimal extraction while preventing over-extraction and bitterness.

Water Quality: Use filtered water for the best taste. The quality of your water significantly impacts the final product.

Experiment with Ratios: While we've provided standard ratios, feel free to adjust to your taste preferences. Some people prefer a stronger concentrate, while others like it milder.

Storage: Properly stored in an airtight container in the refrigerator, your cold brew can last up to two weeks. However, for the best flavor, we recommend consuming it within one week.

Get Creative: Cold brew is incredibly versatile. Try using it in cocktails, smoothies, or even as a base for baked goods!

Troubleshooting Your Cold Brew:

Too Weak?

Increase the amount of coffee being used (leave the amount of water the same)

Steep for a longer time (up to 24 hours)

Use a finer grind (but not too fine, or you'll over-extract)

Too Strong?

Decrease the amount of coffee being used (leave the amount of water the same)

Steep for a shorter time

Dilute more before serving

Tastes Bitter?

Use a coarser grind

Reduce steeping time


Cold brew coffee doesn't have to be complicated or messy. With these two simple methods, you can enjoy smooth, refreshing cold brew at home with minimal effort. Whether you prefer the convenience of single-serve bags or the economy of batch brewing, you're now equipped to create cafe-quality cold brew in your own kitchen.

Remember, the beauty of home brewing is in experimentation. Don't be afraid to adjust ratios, try different coffee beans, or even add flavors to create your perfect cup. At Cold Blooded Caffeine, we're passionate about helping you discover the joys of great coffee, no matter how you brew it.

Stay cool, stay caffeinated, and happy brewing!
