How to Make Coffee with Cold Water

Coffee lovers are always looking for new ways to enjoy their favourite drink, and one question that often arises is: Can you make coffee with cold water? The answer is yes!

Whether you’re trying to make a smooth cold brew, a quick Japanese iced coffee, or just want to experiment, this guide will cover everything you need to know about making coffee with cold water.

Can You Brew Coffee with Cold Water?

Yes, coffee can be brewed with cold water, but the process takes longer than brewing with hot water. The two main methods are:

1. Cold Brew Coffee – Slow extraction over 12-24 hours for a smooth, low-acid coffee.

2. Japanese Iced Coffee – Hot brewed coffee immediately chilled over ice for a crisp, aromatic taste.

Both methods have distinct flavour profiles and are popular for different reasons.

Method 1: Cold Brew Coffee (Smooth & Low-Acidity)

Cold brew coffee is made by steeping coarse coffee grounds in cold water for 12-24 hours. The result? A smooth, naturally sweet, and less acidic coffee that’s perfect for iced drinks.

What You’ll Need to make Cold Brew Coffee:

• 1 cup of coarse ground coffee
• 4 cups of cold filtered water
• A mason jar, French press, or cold brew maker
• A fine mesh strainer or coffee filter

How to Make Cold Brew Coffee:

1. Combine coffee and water: Add the ground coffee to a jar, pitcher, or French press. Pour in cold water and stir gently to ensure all grounds are saturated.

2. Let it steep: Cover and refrigerate for 12-24 hours. The longer it steeps, the stronger the flavour.

3. Strain the coffee: Use a fine mesh strainer, cheesecloth, or coffee filter to separate the grounds from the liquid.

4. Serve & enjoy: Pour over ice and dilute with water, milk, or sweetener as desired.

Expert Tips for A Better Cold Brew:

• Use coarse coffee grounds to prevent over-extraction and bitterness.
• The ideal coffee-to-water ratio is 1:4 for a strong concentrate (dilute before drinking).
•  Store cold brew in the fridge for up to 7 days.

Method 2: Japanese Iced Coffee (Quick & Refreshing)

Unlike a cold brew, Japanese iced coffee is brewed hot but immediately cooled by dripping over ice. This preserves the bright acidity and aroma of fresh coffee.

What You’ll Need to make Japanese Iced Coffee:

• 30g medium-fine ground coffee
• 250ml hot water (about 195-205°F)
• 250g ice cubes
• A pour-over dripper (like a V60 or Chemex)

How to Make Japanese Iced Coffee:

1. Prepare the ice: Fill a carafe or coffee server with 250g of ice.

2. Brew over ice: Place the pour-over dripper on top, add ground coffee, and pour hot water in slow circles, letting the coffee drip onto the ice.

3. Stir & serve: Once brewed, stir the coffee to mix the melted ice with the fresh brew. Pour into a glass and enjoy.

Cold Brew vs. Japanese Iced Coffee: Which One is Right for You?

Both methods are excellent ways to enjoy coffee with cold water, but your choice depends on whether you prefer a mellow or bright flavour.

Can You Just Mix Instant Coffee with Cold Water?

Yes! If you need a quick cold coffee fix, you can mix instant coffee with cold water—it dissolves easily and creates an instant iced coffee.

How to Make Cold Instant Coffee:

•  1-2 teaspoons of instant coffee
• 1 cup of cold water or milk
•  Ice cubes and sugar (optional)
• Stir until dissolved & enjoy!

While not as flavourful as cold brew or Japanese iced coffee, it’s an extremely easy way to get iced coffee in seconds.
