What is Cold Brew Coffee?
Cold brew is not the same as iced coffee. Most people assume they’re identical, they’re not.
Iced coffee is just regular hot-brewed coffee poured over ice. Cold brew, on the other hand, is brewed entirely in cold (or room temperature) water over a long period usually 12 to 24 hours. This slow extraction creates a concentrate that’s:
- Smoother and less bitter than regular coffee
- Lower in acidity (great if coffee upsets your stomach)
- Naturally sweeter tasting without any added sugar
- Higher in caffeine per sip (it’s a concentrate!)
| Fun Fact: Cold brew can last up to 2 weeks in the fridge – making it the ideal “meal prep” drink for busy weekday mornings! |
What You Need: Ingredients & Coffee-to-Water Ratio
The best part? You need almost nothing special. Here’s your complete shopping list:
| Item | What to Use | Notes |
|---|---|---|
| Coffee Beans | Medium or dark roast coarsely ground | Brands: Blue Tokai, Subko, Nescafe Gold for budget option |
| Water | Filtered or bottled water | Avoid hard tap water – affects flavour |
| Container | A large mason jar or any glass jar | At least 1 litre capacity |
| Strainer | Fine mesh strainer + coffee filter or muslin cloth | Paper filters also work |
| Fridge | Any standard refrigerator works | Or steep at room temperature |
The Golden Ratio: Coffee to Water
Get this right and your cold brew will never taste weak or too strong again:
| Brew Strength | Coffee | Water | Yield |
|---|---|---|---|
| Concentrate (recommended) | 1 cup (100g) | 2 cups (500ml) water | Dilute 1:1 with water/milk before drinking |
| Ready-to-Drink | 1 cup (100g) | 4 cups (1 litre) water | Drink straight – less strong |
| Extra Strong | 1 cup (100g) | 1.5 cups (375ml) water | Strong concentrate for recipes |
| Pro Tip: If you’re a beginner, start with the ready-to-drink ratio (1:8 by weight). You can always make it stronger next time once you know your preference! |
How to Make Cold Brew Coffee at Home: Step-by-Step
Read below to learn how to make cold brew coffee at home in 5 minutes:
Step 1: Grind Your Coffee (Coarse!)
This is the most important step most beginners get wrong. You need a COARSE grind think the texture of raw brown sugar or breadcrumbs. Too fine, and your cold brew turns out muddy and bitter.
If you don’t have a grinder, ask your local coffee shop to grind it coarse for you most will do it happily.
Step 2: Add Coffee to Your Jar
Add your coarsely ground coffee to a clean glass jar. For a 1 litre batch using ready to drink ratio, that’s about 100g (or 1 cup) of ground coffee.
Step 3: Pour in Cold Water
Slowly pour cold or room temperature filtered water over the grounds. Give it a gentle stir to make sure all the coffee is wet and no dry clumps remain at the top.
Step 4: Cover and Steep for 12-24 Hours
Put the lid on (or cover with a cloth) and place it in the fridge. Now the hardest part wait.
- 12 hours → lighter, smoother brew
- 16–18 hours → balanced, rich flavour (sweet spot for most people)
- 24 hours → strong, bold, concentrated
First time? Go for 16 hours. You can adjust from there.
Step 5: Strain and Store
Once steeped, pour the liquid through a fine mesh strainer lined with a coffee filter or muslin cloth into a clean bottle. Squeeze gently to extract all the liquid. Discard the spent grounds.
Your cold brew is ready! Store in the fridge in a sealed bottle , it stays fresh for up to 2 weeks.

Frequently Asked Questions (FAQ)
Q1: What is the ratio of coffee to water for cold brew?
The standard ratio is 1:8 by weight – 1 part coffee to 8 parts water for a ready to drink cold brew. For a stronger concentrate (to dilute later), use 1:4. Most beginners start with 1:8 and adjust from there.
Q2: How long to steep cold brew coffee for the best flavor?
If you’re wondering how long to steep cold brew, the ideal time is 12–24 hours for a smooth, rich taste. However, for quick methods, you can steep for a shorter duration using a stronger ratio and coarse grind cold brew coffee.
Q3: Can you use regular coffee powder for cold brew?
Technically yes, but it’s not recommended. Regular (fine ground) coffee will make your cold brew gritty and harder to strain. Always use coarsely ground coffee beans for the best result. If you only have instant coffee powder, it won’t work – cold brew requires actual coffee grounds.
Q4: What is the ideal cold brew coffee ratio for beginners?
The standard cold brew coffee ratio is 1:4 (coffee to water) for concentrate and 1:8 for ready-to-drink coffee. Adjust the ratio depending on your taste preference and the strength you want from your cold brew coffee recipe.
Q5: Does cold brew have more caffeine than regular coffee?
The cold brew concentrate itself has more caffeine per ml – but when you dilute it 1:1 with water or milk before drinking, the caffeine level is similar to or slightly higher than regular coffee. If you drink it as a concentrate (undiluted) yes, it’s significantly stronger.
Q6: What is the difference between cold brew vs iced coffee?
Understanding cold brew vs iced coffee is key: cold brew is steeped slowly in cold water, resulting in a smoother, less acidic taste, while iced coffee is brewed hot and then chilled, often leading to a more bitter flavor.
Q7: What are the best coffee beans for cold brew?
The best coffee beans for cold brew are medium to dark roast beans with chocolatey or nutty notes. Pair them with a coarse grind cold brew coffee for optimal extraction and a balanced flavor
Q8: What equipment do I need to make cold brew coffee at home?
To understand how to make cold brew coffee at home, you don’t need fancy equipment. A jar, a spoon, water, and coarse grind cold brew coffee are enough. You can strain it using a simple cloth, sieve, or coffee filter for a smooth cold brew coffee recipe.
