The biggest difference is how the coffee was brewed. Cold brew is coffee steeped in room-temperature or cooler water, and iced coffee is coffee brewed hot in the usual way and then cooled down to serve. Both are drunk cold, but the process differs, so the character of the taste differs too.
How is cold brew made?
The guidance site run by the National Coffee Association (NCA) describes cold brew as coffee made with room-temperature or cooler water, and points out that the name comes from how it is made, not how it is served. It takes a long time to steep. The source gives roughly 12 hours of contact between coffee and water as a typical example, and adds that the range is wide, from a few minutes to 12-18 hours or more depending on the method.
It advises starting with a coarse grind. The ratio given is 1 g of coffee to 4-5 g of water (1:4 to 1:5), which should be understood as a strong concentrate rather than a ready-to-drink strength. The concentrate is mixed with water or milk, and finished cold brew can be served right away or chilled in the refrigerator.
How is iced coffee different?
Iced coffee is first brewed with hot water in the usual way, then cooled before drinking. Hot water extracts flavor quickly, and ice is often used in the cooling step. Brewing it stronger so ice does not water it down is a common home-cafe habit, not an official standard.
How does the taste feel different?
The same source explains that extracting at a lower temperature for longer gives a smoother, more mellow cup, and says cold brew tastes less bitter. Iced coffee follows the usual hot brewing method, so it is closer to the taste of the coffee you normally drink. Taste still depends on the beans and brewing conditions, so treat this as a reference only.
Figures for caffeine differ from source to source, so I do not say which one has more. Check the daily recommended maximum separately under the MFDS standard.
Which one should you choose?
There is no right answer; choose by situation. If you have time to prepare ahead and want a mellow taste, cold brew fits. If you need a cup right now, brewing hot and cooling it is the realistic choice. Cold brew has to be steeped beforehand, so it takes planning, such as preparing it the evening before.
If you want to compare them at home, make both from the same beans side by side and taste. With the same beans you only feel the difference in method, which makes it easier to see which suits you. This is a general comparison tip, and it cannot be said that one is better.
Frequently asked questions
Is every coffee with ice cold brew?
No. Cold brew refers to coffee steeped in cool or room-temperature water. Hot-brewed coffee poured over ice is iced coffee.
Can I make cold brew at home?
Yes. Steep coarsely ground beans in cool or room-temperature water for a long time. Start within the guided range for time and ratio and adjust to taste. Afterward, keep it chilled in the refrigerator.
Why is cold brew smoother?
The guidance explains it by the lower temperature and longer extraction. Still, even the same beans vary with grind size and time.
