Cold Brew vs Iced Coffee: What's the Difference?

When it comes to chilled caffeine fixes, not all iced coffees are created equal. Two popular options that often cause confusion are cold brew and traditional iced coffee. While they may look similar in your glass, these cool concoctions have some key differences in how they're made and how they taste.

What is cold brew coffee?

Cold brew coffee is made by steeping coffee in cold or room temperature water for an extended period - usually for 12 to 24 hours. This slow extraction process results in a smooth, mellow flavour profile that’s less acidic. 

The beauty of cold brew lies in its versatility; it can be enjoyed straight, with milk or cream, or even as a base for various cocktails. Many coffee enthusiasts appreciate its rich, chocolatey notes and its ability to be made in large batches, making it a perfect choice for summer gatherings or busy mornings. 

How to Make Cold Brew Coffee

Making cold brew coffee at home is simple and requires just a few ingredients and tools. Here’s a step-by-step guide to help you craft your own:

Ingredients

• Coarsely Ground Coffee: For the best flavour, use high-quality beans. A coffee-to-water ratio of 1:4 is a good starting point.
• Cold or Room Temperature Water: Filtered water works best to enhance the taste.

Tools

• A Large Jar or Pitcher
• A Fine Mesh Strainer or Cheesecloth

Instructions

1. Combine your coffee and water in your jar or pitcher. Mix the grounds with the cold or room-temperature water and stir gently to make sure they're all saturated.
   
   
2. Cover the jar and let it steep in the fridge or at room temperature for 12 to 24 hours. The longer you leave it, the stronger the flavour will be.
   
   
3. After letting it sit for a while, filter the coffee grounds using a fine mesh strainer or cheesecloth. You can strain it multiple times for a smoother finish.
   
   
4. Dilute your concentrate with water, milk, or a milk alternative, depending on what you love. Serve it over ice, and enjoy!
   
   
5. Any leftover cold brew can be stored in the fridge in a closed-top container for 2-7 days, making it an easy option for busy days!

What is iced coffee?

Iced coffee is made by brewing coffee hot and then cooling it down, typically served over ice. This method preserves the bright and bold flavours. Unlike cold brew, which is immersed in cold water, iced coffee starts with hot coffee, making it a quicker option.

The flavour profile will vary widely depending on the type of coffee beans used, the brewing method, and any additional ingredients like milk, cream, or flavoured syrups. It’s a versatile drink that can be customised to suit your taste - perfect for everything from a morning boost to an afternoon treat.

How to Make Traditional Iced Coffee

Making iced coffee at home is easy, so you can enjoy a refreshing cup in no time. Here’s a simple guide to help you whip up your own:

Ingredients

• Freshly Hot Coffee: Use your favourite beans brewed hot.
• Ice Cubes: Regular ice or coffee ice cubes (made from frozen coffee) for a stronger flavour.

Tools

• Espresso Coffee Machine, French Press or a Drip Coffee Maker like a Hario V60
• Glass or Pitcher

Instructions

1. Start by brewing a strong cup of coffee using your preferred method. For a bolder flavour, use a coffee-to-water ratio of 2:6.
   
   
2. Let it cool to room temperature. You can speed up this process by placing it in the fridge for about 10-15 minutes.
   
   
3. Fill a glass with ice cubes. If you’re using coffee ice cubes, this will help prevent dilution as they melt.
   
   
4. Pour the cooled coffee over the ice in your glass. Add milk, cream, or sweetener as desired, and stir gently.
   
   
5. Sip and enjoy!

What are the key differences between cold brew and iced coffee?

While cold brew and iced coffee may seem similar at first glance, they have distinct differences that may influence your choice. 

Flavour & Acidity 

Cold brew is known for its smooth, mellow taste. The extended steeping time in cold water extracts fewer bitter compounds, resulting in a rich, chocolatey flavour that many find more palatable. Whereas iced coffee retains the bright and bold flavours of hot coffee. Depending on the beans used and the brewing method, iced coffee can have a sharper taste and higher acidity due to the quick cooling process.

Caffeine Levels 

Cold brew typically has a higher caffeine concentration because of the longer steeping time and coffee-to-water ratio. However, since it’s often diluted before serving, the final caffeine content can vary. Iced coffee usually contains less caffeine than cold brew if it's made with a standard ratio. But, if you brew a strong cup and serve it over ice without dilution, it can still pack quite a punch.

Brewing Process

Cold brew is made by infusing the grounds in cold water over a long period of time, which relies on time instead of heat to extract flavours. Iced coffee is brewed like regular hot coffee and then poured over ice to cool it down. This is typically more straightforward and convenient for those who want a refreshing drink without the wait. There are also variations in the brewing method, like Japanese iced coffee, which adds a unique twist to the traditional iced coffee experience.
