Cold Brew vs. Iced Coffee: What’s the Difference?
They both come over ice. They both have caffeine. But cold brew and iced coffee are made completely differently, taste completely different, and even have different caffeine levels. Here’s the breakdown.
How Iced Coffee Is Made
Iced coffee is exactly what it sounds like: hot-brewed coffee poured over ice. The coffee is brewed at normal hot temperatures (195–205°F), typically at double strength to account for dilution when ice melts, then cooled down.
The result is a bright, acidic, lighter-bodied drink that tastes like a cold version of regular coffee. It’s quick to make — brew time is the same as any hot coffee, usually 3–5 minutes.
How Cold Brew Is Made
Cold brew never touches hot water. Coarsely ground coffee is steeped in cold or room-temperature water for 12–24 hours, then filtered. The long extraction time pulls different compounds from the beans than hot brewing does.
The result is a smooth, low-acid, full-bodied concentrate that’s naturally sweeter and less bitter than hot-brewed coffee. It’s typically diluted with water or milk before serving. Check our cold brew brewing guide for the full method.
Taste Comparison
| Iced Coffee | Cold Brew | |
|---|---|---|
| Flavor | Bright, acidic, crisp | Smooth, sweet, chocolatey |
| Acidity | Higher (same as hot coffee) | ~67% less acid |
| Body | Light to medium | Full, rich |
| Bitterness | Can be bitter | Very low bitterness |
| Sweetness | Low | Naturally sweeter |
Caffeine Content
Cold brew concentrate has more caffeine per ounce than regular coffee because of the long steep time and higher coffee-to-water ratio. But since it’s typically diluted, a served glass of cold brew has roughly 150–200mg of caffeine per 16oz, compared to 120–180mg for iced coffee.
That said, caffeine content varies depending on the beans, grind, and ratio. In general, cold brew hits a little harder.
Which Beans Work Best?
For iced coffee: Light to medium roasts work well because the acidity and fruit notes stay vibrant when chilled. Try our Ethiopia Yirgacheffe or Kenya AA iced — the bright fruit flavors pop.
For cold brew: Medium to dark roasts shine because the long steep emphasizes chocolate, caramel, and nut notes while minimizing acidity. Brazil Sul de Minas, Colombia Supremo, and Sumatra Mandheling all make excellent cold brew.
Cost Comparison
Cold brew uses roughly 2x the coffee grounds as iced coffee for the same volume, so it costs more to make at home. At coffee shops, cold brew typically costs $1–$2 more per cup for the same reason.
The trade-off: cold brew concentrate keeps in the fridge for up to 2 weeks, so you can make a big batch and have ready-to-pour coffee all week. That convenience factor often makes up for the higher bean usage.
When to Order Which
- Choose iced coffee when: You want something bright and refreshing, you like fruity or acidic flavors, or you want your coffee fast.
- Choose cold brew when: You want something smooth and strong, you prefer low acidity, you don’t like bitter coffee, or you want to batch-prep for the week.
Make It at Home
Both are easy to make at home with quality beans. For cold brew, all you need is a jar, a filter, coarsely ground coffee, and 12–24 hours of patience. Our cold brew guide walks you through the exact ratios and timing.
For iced coffee, brew your favorite method at double strength and pour over a full glass of ice. A pour-over makes an especially clean iced coffee.
