How to Make Homemade Cold Brew Coffee

I have been such a devoted coffee drinker for a while now.

And while it has its negative effects, it also has its benefits. 

Over time, I have come to understand that coffee—like many good things in life—is best enjoyed in moderation. 

That’s where the magic really happens.

When consumed mindfully, it actually supports you. 

Beyond boosting energy due to its caffeine content, it offers several health benefits.

These include a lower risk of type 2 diabetes, heart failure, and even Parkinson’s disease.

It is also rich in antioxidants that support brain health, protect the liver, and can improve mood, metabolic rate, and overall cognitive function.

Good stuff for ya body, ya feel me?😀

And that’s how I’ve grown into the practice of drinking coffee and made it part and parcel of my morning routine.

As I’ve deepened this practice, I’ve also come to appreciate that the taste of coffee is truly something special.

It’s one of those simple pleasures that keeps me coming back.

But here’s the thing I’ve learned: to truly enjoy coffee, how it is made matters just as much as the coffee itself.

There are various ways to prepare this beloved beverage.

Popular methods include using a drip machine, moka pot, cold brewing, French press, or simply pouring hot water over ground coffee.

Most of these methods rely on heat to extract flavour from the coffee grounds.

All except one: Cold Brew Coffee.

Cold brew relies on something different.

It relies on time.

In this blog, I will share how I make my cold brew to extract a flavour that gives me a really great cup of coffee—one that keeps me hooked on this method.


Why Cold Brew?

Before diving into the process, it’s worth understanding why cold brew stands out.

Cold brew coffee is smoother, less acidic, and often naturally sweeter than hot-brewed coffee.

Because it is extracted slowly using room temperature or cold water, it doesn’t pull out the same bitter compounds that hot water does.

For me, this means:

  • A gentler experience on the stomach
  • A more balanced, mellow flavour
  • A refreshing alternative, especially on warm days

It’s also incredibly convenient—you can prepare it ahead of time and have it ready when you need it.


The Conditions to Consider (And Why They Matter)

Making cold brew is simple but getting it right depends on a few key factors.

These are the variables that determine whether your coffee turns out average or exceptional.

1. Temperature

Cold brew doesn’t use heat, which is what makes it unique.

Using room temperature or cold water slows down the extraction process.

This slower extraction:

  • Reduces bitterness
  • Enhances smoothness
  • Preserves subtle flavour notes

If your water is too warm, you may start extracting compounds that make the coffee taste harsh.

2. Quantity (Coffee-to-Water Ratio)

The ratio of coffee to water is crucial.

A common guideline is 1:16 (coffee to water).

This ratio produces a balanced brew—not too strong, not too weak.

Of course, this is flexible.

If you like a stronger brew, you can slightly increase the coffee amount.

3. Water Quality

Water is often overlooked, but it makes up most of your cup.

Using clean, fresh water ensures:

  • No unwanted flavours
  • A cleaner, brighter taste

If your water has a strong taste (like chlorine), it will affect your coffee.

So always use filtered or clean drinking water where possible.

4. Time

Time is the heart of cold brew.

Unlike hot brewing methods that take minutes, cold brew takes 16–20 hours.

This extended steeping time allows for a gentle and complete extraction.

  • Less than 12 hours → under-extracted, weak flavour
  • 16–20 hours → balanced and full-bodied
  • More than 24 hours → can become overly strong or dull

Patience here truly pays off.

5. The Roast and Type of Beans

The type of coffee beans you use will shape your entire experience.

  • Light roast → brighter, more acidic notes
  • Medium roast → balanced flavour (my personal preference)
  • Dark roast → bold, chocolatey, slightly bitter

For cold brew, medium to dark roasts tend to work beautifully because they bring out rich, smooth flavours.

Also, coarsely ground coffee is ideal.

Fine grounds can make your brew cloudy and harder to filter.

If you have access to Ugandan coffee, it is such a great option to explore. 

Uganda is known for producing high-quality coffee, especially its rich and full-bodied Robusta and increasingly appreciated Arabica varieties from regions like Mount Elgon and the Rwenzori. 

These beans often have deep chocolatey notes, earthy undertones, and a natural boldness that translates beautifully into cold brew.


What You Will Need (For One Serving)

Here’s what I use for a simple, satisfying cup:

  • A container with a lid
  • 1.5 tablespoons of your favourite coffee (my sweet spot)
  • A spoon or stirrer
  • 500 ml of clean water at room temperature
  • A sieve (or filter)

You don’t need fancy equipment.

That’s one of the things I love most about this process—it’s accessible and easy.


Step-by-Step Procedure

Here’s how I make my cold brew at home:

Step 1: Add Coffee to Your Container

Start by adding your coffee grounds into your container.

I usually go with 1.5 tablespoons, but feel free to adjust depending on how strong you like it.

Step 2: Pour Water Over the Coffee

Slowly pour your water over the coffee grounds.

Step 3: Stir Gently

Use a spoon or stirrer to ensure all the coffee grounds are fully soaked.

This step is important because dry pockets can form when water is poured over coffee, especially with cold water.

Step 4: Cover and Let It Sit

Close your container with a lid and let the mixture sit for 16–20 hours at room temperature.

This is where the magic happens.

Step 5: Strain the Coffee

Once the time has elapsed, use a sieve to separate the liquid from the coffee grounds.

Step 6: Serve and Enjoy

Your cold brew is now ready.

You can:

  • Drink it as is
  • Add ice
  • Dilute it slightly with water or milk
  • Sweeten it if you like

Personally, I enjoy it in its pure form—it allows me to fully experience the flavour.


Final Thoughts

Cold brew has become more than just a method of making coffee for me.

It’s a ritual.

There’s something deeply satisfying about preparing something in advance, letting time do its work, and then coming back to enjoy the result.

Good things do take time and that’s the lesson I get every time I sip on my homemade cold brew coffee.

What I also love is how adaptable it is.

You can experiment with:

  • Different beans
  • Different ratios
  • Different steeping times

Over time, you begin to discover your own “sweet spot”—that perfect balance that feels uniquely yours.

And perhaps that’s the beauty of it.

Coffee, in its simplest form, becomes personal.

And for those of us in Uganda, there’s something even more special—we have access to some of the world’s finest coffee right at home.

So if you’re looking for a smoother, more intentional way to enjoy your coffee, I highly recommend trying cold brew at home.

It doesn’t require much—just a few ingredients, a bit of time, and a willingness to experiment.

And who knows?

It might just become part of your routine too, just like it has become part of mine.
