Cold Brew vs Iced Coffee: Key Differences, Caffeine & Flavour Compared
When the weather warms up, many coffee lovers switch to chilled brews. But not all cold coffee is created equal. Two of the most popular options, cold brew and iced coffee, might look similar, but they differ in everything from flavour to caffeine to how they’re made.
In this guide, we’ll explore the differences between cold brew and iced coffee, including how they’re brewed, what they taste like, how much caffeine they contain, and which one might be best for you.
Brewing Methods: Hot vs. Cold
Cold Brew
Cold brew coffee is made by steeping coarsely ground coffee in cold or room temperature water for 12 to 24 hours. This long, slow extraction creates a concentrated coffee that is then filtered and diluted with water or milk to serve. It’s completely heat-free, which significantly changes its taste and chemistry.
Best for: Smooth, mellow flavour lovers
- Why it works: This microlot coffee is processed using the ice-process method, which enhances sweetness and body—perfect traits for cold brew. Its sugar cane and stone fruit notes remain vibrant even when steeped cold.
- Profile: Full-bodied, sweet, with bright fruit undertones.
- Ideal for: Rich, intense cold brew with complex flavours.
Iced Coffee
Iced coffee starts as hot coffee, brewed using a method like pour-over, drip machine, or French press. Once brewed, it’s cooled and poured over ice. The result is a drink that maintains the original flavour profile of hot coffee but with a refreshing chill.
Best for: Fans of brighter, more acidic coffee
Tip: Brew it strong to account for ice dilution
- Why it works: These naturally fermented beans unlock a bold, fruit-forward sweetness that stands up beautifully in iced coffee. The juicy flavour—combining raspberry, green apple, tropical fruit, pineapple and caramel—adds vibrant complexity.
- Profile: Medium-bodied with bright citrus acidity; juicy stone fruit and berry notes; a soft hibiscus floral finish and a refreshing lime aftertaste.
- Ideal for: Creating a rich, intense cold brew with layered fruitiness and rounded sweetness, perfect for black or milk-based serves.
Taste & Flavour Profile
Cold Brew
Cold brew is known for its smooth, naturally sweet, and low-acidity taste. Because the brewing process extracts fewer bitter compounds, the final cup has a rounder, less acidic profile, even when enjoyed black. It’s often described as chocolatey or syrupy, making it a favourite for slow sipping.
Iced Coffee
Iced coffee tends to be brighter and more acidic, with sharper, fruitier notes preserved from the beans. However, it can taste bitter or watery if not brewed strong enough or if left to melt too much.
Caffeine Content: Which Packs a Punch?
Generally, cold brew contains more caffeine than iced coffee. Because it’s brewed as a concentrate and often uses a higher coffee-to-water ratio, a single glass of cold brew can have 200–300mg of caffeine, compared to 100–150mg in a typical iced coffee.
However, the actual caffeine content depends on:
- The brew ratio
- The bean type
- How much water or milk is added before serving

Health Benefits & Acidity
Cold brew’s lower acidity is gentler on sensitive stomachs and may help reduce acid reflux or heartburn. Many also find they can drink it with less sugar or milk due to its naturally sweet flavour, making it a lower-calorie option overall.
In contrast, iced coffee retains much of the acidity found in hot coffee, which may be less suitable for some people with digestive sensitivities.

FAQs
What’s the difference between cold brew and iced coffee?
Cold brew is steeped in cold water for 12–24 hours, while iced coffee is brewed hot then chilled. The result is smoother, less acidic coffee for cold brew and a brighter, more acidic taste for iced coffee.
Is cold brew stronger than iced coffee?
Yes, in most cases. Cold brew typically has more caffeine per ounce because it’s brewed as a concentrate.
Can you use any coffee for cold brew?
Technically yes, but medium-to-dark roasts with nutty, chocolatey profiles tend to shine in cold brew. Lighter roasts can taste too sour when cold brewed.
How long does cold brew last in the fridge?
Up to two weeks, though flavour is best in the first 5–7 days.
