When the weather gets warmer, many people prefer a cold coffee. But as soon as you delve deeper into the world of coffee, you'll quickly encounter two terms that are often used synonymously, but are actually quite different: Cold Brew and Iced Coffee .
Although both drinks are served over ice, they differ fundamentally in preparation, taste, intensity, and effect . This article clarifies the differences precisely, practically, and with all the relevant background information – so you can find the method that truly suits you.
What is cold brew?
Cold brew is a cold-extracted coffee prepared entirely without heat. This means that coarsely ground coffee is steeped in cold or room-temperature water for many hours – usually between 12 and 24 hours.
This slow, temperature-independent extraction process releases different components from the coffee grounds compared to hot brewing. This has far-reaching effects on taste, texture, and caffeine content.
Typical sequence of events:
- Coarse grind (French Press level)
- Ratio approximately 1:8 to 1:10 (e.g., 80 g coffee to 800 ml water)
- Brewing time: minimum 12, maximum 24 hours
- Then filter (sieve, paper filter or French press)
- Keep refrigerated, shelf life up to 5 days.
The result is:
- Particularly mild in taste
-
Hardly any acidity or bitterness , often with chocolatey, nutty notes.
-
High caffeine content , depending on concentration and bean variety.
- Pleasantly smooth and slightly sweet – also very drinkable on its own.
Cold brew is ideal for people with sensitive stomachs or for those who want a constant supply of cold coffee.
What is iced coffee?
In contrast, iced coffee is a drink based on classic hot extraction . The coffee is therefore prepared normally with hot water (e.g., using a hand filter, Aeropress, or espresso machine) and then cooled over ice.
There are two variants:
-
Iced coffee : Here you brew a hot coffee, let it cool briefly, and then pour it over ice. Disadvantage: The taste can change, and aromas are lost.
-
Japanese Iced Coffee : The more elegant method. You replace some of the brewing water with ice and pour the hot coffee directly onto the ice cubes. The coffee is cooled down immediately, which preserves its aromas and freshness .
The result is:
-
Lively and aromatic , especially with lighter roasts.
-
Significantly higher acidity , more freshness
-
Less caffeine than cold brew (depending on preparation)
- Must be drunk fresh , not suitable for storage.
Iced coffee is particularly suitable for fruity bean profiles if you are looking for clear, vibrant notes – for example, citrus, berries or floral aromas.

Which method is suitable for whom?
Cold brew is especially suitable if you:
- You want a stomach-friendly , low-acid coffee?
-
If you want to brew in advance and save time
- You like to combine your coffee with milk, syrup or ice cream
- looking for a strong but mild-tasting caffeine kick
- prefer darker, nuttier beans
Iced coffee is ideal for you if you:
- I prefer coffee that is fruity, complex and clear.
-
You want to decide spontaneously when you drink cold coffee.
- you don't want to plan for long steeping times
- preferably work with light roasts
- Do you like your coffee plain or lightly sweetened?
Both methods have their place – the choice depends on your taste, your daily routine and your time budget.
Detailed preparation tips
Cold Brew – here's how it works:
- Grind the coffee coarsely (about the size of sea salt)
- Mix coffee and water in a ratio of 1:8 to 1:10 (depending on the desired strength).
- Pour into an airtight glass or a special cold brew carafe.
- Allow to steep for at least 12 hours, ideally at 4–8 °C in the refrigerator.
- Then filter (e.g. with a sieve, paper filter or French press)
- Keep refrigerated – serve neat, on ice or diluted
Tip: Cold brew is highly concentrated. Dilute it in a glass with cold water or plant-based milk in a 1:1 ratio, depending on your taste.
Iced Coffee – two proven methods:
Option 1: Classic Iced Coffee
- Brew filter coffee as usual.
- Let it cool down a bit (do not pour hot onto the ice)
- Serve over ice cubes, sweeten to taste.
Variant 2: Japanese Iced Coffee
- Replace half of the brewing water with ice.
- Brew directly onto the ice in the carafe.
- Serve immediately – especially aromatic and fresh
Tip: Use high-quality ice cubes made from filtered water so that the taste is not diluted.
Common mistakes with both methods
|
Mistake
|
consequence
|
Solution
|
|
Letting cold brew steep for too long
|
Flat, slightly musty taste
|
Limit the steeping time to 12–18 hours.
|
|
Grind too fine for cold brew
|
Cloudy result, over-extraction
|
Grind coarsely, as for French press.
|
|
Iced coffee with too little coffee
|
Diluted result
|
Adjust brewing strength (more coffee grounds, less water)
|
|
Ice is melting too quickly
|
Too watery, aroma flattened
|
Use large, solid ice cubes
|
|
Wrong choice of beans
|
The taste doesn't match the preparation method.
|
Choose darker roasts for cold brew and lighter roasts for iced coffee.
|
Conclusion: Two methods, two completely different experiences
Whether you prefer cold brew or iced coffee is not a question of right or wrong – but a question of style, preparation logic and your taste preferences.
Cold brew represents slowness, smoothness, and preservation , while iced coffee stands for spontaneity, freshness, and aromatic clarity . Both have their strengths – and both are worth preparing consciously and understanding in terms of taste.
If you don't yet have a clear preference, the recommendation is: Try both methods with the same bean – and taste the difference. This way you'll develop a better feel for extraction, flavor profile, and brewing techniques. And above all: You'll discover just how diverse coffee can be, even as a cold drink.
