The weather is warming up, so it's time for icy cold drinks!
If you're looking for an iced coffee alternative that doesn't have any caffeine, then decaf iced coffee is perfect for you.
In this article, I'll explain what decaf iced coffee is, how to make it at home using a few simple ingredients, and how to customize it to suit your taste.
Grab a cup of coffee, and let's get started!

What is decaf iced coffee?
Decaf iced coffee is coffee that has been brewed with decaffeinated coffee beans.
Decaf iced coffee can be just as delicious as its caffeinated counterpart, as it doesn't taste very different from regular coffee beans, but more on this later.
You can make decaf iced coffee the same way you would with regular coffee beans. If you haven't made iced coffee before, I suggest reading this article first.
Over there, I'll show you all the ways you can make iced coffee at home using different techniques.

What does decaf iced coffee taste like?
Decaf iced coffee tastes like regular iced coffee but without the caffeine kick.
Some say that decaf iced coffee tastes a bit sweeter and more acidic than regular iced coffee, but this is generally due to the way the coffee beans are processed.
Additionally, if you dislike the taste of your decaf iced coffee, you can add delicious add-ins to mask it (such as vanilla syrup), which we will discuss further later in the article.
Which ingredients are needed to make decaf iced coffee?
Decaf iced coffee is really easy to make and only requires a few simple ingredients:
- Decaf brewed coffee
- Ice cubes

You can use any coffee brewer you have at home to make the decaf coffee. I'll go over some of the best options below.
There are also many ways to sweeten your iced coffee once it's finished. This will allow you to customize the coffee to your taste completely.
What are decaf coffee beans?
Decaf coffee beans undergo a decaffeination process to remove most of the caffeine.
Decaffeination is typically done by one of two methods: chemical or the Swiss Water Process. (Source)

Decaf coffee beans still contain a small amount of caffeine, typically around 2-15 mg per cup, which is significantly less than in traditional caffeinated coffee.
Many people choose to drink decaf coffee for the taste without the worry of consuming too much caffeine.
What is the coffee-to-water ratio for decaf iced coffee?
I always brew iced coffee with a higher coffee-to-water ratio, such as 1:14, which yields 18 grams of coffee per one cup of water (250 ml).
Because you will dilute the coffee with the ice cubes once it's served, it's best to brew with more coffee to retain most of its strength.
If you like adding a sweetener to your coffee, I still suggest brewing it with a higher ratio for the most enjoyable iced coffee.
Tip: Make a few decaf coffee ice cubes if you want to keep the maximum strength possible. Check out this complete guide to learn how to make them.
What is the best brewing technique for iced coffee?
The flavor profile of your iced coffee will change depending on the technique used. You can have a look below at the flavor profiles:
- Chemex coffee will make a well-balanced and refreshing iced coffee.
- French press coffee will make the most robust version.
- The Hario V60 is ideal for one-cup recipes and produces a well-balanced iced coffee.
You can choose a coffee brewer that you like most for this recipe. Most of the time, I'll use a pour over technique for its ease of use.
You'd be better off with French press coffee for the most strength.

I recommend using the higher coffee-to-water ratio for the above-listed coffee brewers. You'll get the most delicious decaf iced coffee that way.
Can you also make cold brew with decaf coffee beans?
Yes, you can make cold brew with decaf coffee beans.
However, it's essential to note that the flavor of cold brew made with decaf coffee beans will differ from that of cold brew made with caffeinated coffee beans.

Decaf coffee beans tend to produce a milder and slightly sweeter flavor than caffeinated coffee beans, so your resulting cold brew may have a slightly different flavor profile compared to one made with caffeinated coffee beans.
To counteract this, I use a higher coffee-to-water ratio for cold brew coffee, which I also apply to this decaf iced coffee.
