Cold brew and iced coffee both deliver cold caffeine, but they’re made completely differently. Understanding the difference helps you choose the right one for your taste and time budget.
Quick Answer: Cold brew steeps coffee grounds in cold water for 12-24 hours, creating smooth, less acidic coffee. Iced coffee is regular hot-brewed coffee poured over ice, taking 5 minutes but tasting more acidic. Cold brew costs $4-6 at cafes, iced coffee costs $2-4.
Brewing Method
Cold brew requires patience. Mix coarse coffee grounds with cold water at a 1:4 ratio and let sit for 12-24 hours. Strain out grounds and you have concentrated coffee to dilute with water or milk.
Iced coffee is instant gratification. Brew hot coffee double-strength, pour over ice, and drink immediately. The ice melts and dilutes it to normal strength.
Taste Difference
Cold brew tastes smooth, sweet, and naturally less bitter. The cold water extracts fewer acids and oils from the beans. Many people drink it black without sugar.
Iced coffee has the same bright, acidic taste as hot coffee – just cold. Some people find it harsh without added milk or sweetener. The flavor is more complex but can taste sour if it sits too long.
Caffeine Content
- Cold Brew: 150-200mg per 8 oz (when diluted)
- Iced Coffee: 95-120mg per 8 oz
- Regular Hot Coffee: 95-120mg per 8 oz
Cold brew packs more caffeine because it uses more coffee grounds. The long steeping time extracts more caffeine from the beans. If you’re sensitive to caffeine, iced coffee might be the better choice.
Shelf Life
Cold brew concentrate stays fresh in the fridge for up to 2 weeks. Make a batch on Sunday and have cold coffee all week. Iced coffee should be consumed within 2 hours or it develops off flavors. Hot coffee oxidizes quickly once it cools.
Making Cold Brew at Home
You can make cold brew with any container, but dedicated cold brew makers make the process easier. They include built-in filters for easy straining. Large glass jars with tight-sealing lids work perfectly for making cold brew concentrate at home.
