The Best Ratio to make Cold brew is 1:7 meaning 1 part Coffee and 7 parts of Water.
And I recommend letting your cold brew coffee steep at room temperature for 12 to 14 hours.
Cold Brew Recipe
To make 4 cups or 1 liter of cold brew coffee:
- Mix a little more than 1/2 cup of your preferred ground coffee with 4 cups of filtered water.
- Ensure all the ground coffee have been totally immersed in the water
- Let the mixture steep in an airtight container for 12-14 hours at room temperature
- Once steeped filter the mixture using a cheesecloth or a coffee filter into a separate container
- Now proceed to taste your brew, if its too strong add more water
- Once its the right taste you can either add ice or refrigerate the brew to make it nice and chilled.
- You can see how it is done in the video below.

Why is this the Best Ratio for Cold brew
Before I first made cold brew coffee I did tons of research and the ratio 1:7 kept popping up everywhere from coffee shops to amateurs both recommended this as the ideal ratio.
This ratio consistently produces the right blend of cold brew coffee meaning that it is not too strong or too weak.
What I advise everyone to do is to taste your cold brew once it has steeped and been filtered, now if it is too strong you can always add some more water until its the right consistency for you.
Cold brew Coffee Ratio Grams
If you are using metric measurement its around 140 grams of coffee to around 1 liter of water.
Why Do You Need So High Ratio Of Coffee to Water
I know a lot of you are wondering why do you need so much coffee to make Cold Brew.
Whilst in comparison to brewing normal coffee you tend to use a lot less.
The main reason for this is that cold brew coffee doesn’t use heat to brew so instead it relies on diffusion.
Normal coffee is brewed using heat around 195 F (91 C) and 205 F (96 C) which excites the coffee grinds and releases a wide range of compounds into your brew.
Some of these compounds released by the heat can be acidic which is what usually gives your coffee it’s intense taste and also for some unlucky individuals will cause stomach issues such as acid reflux.
Cold brew coffee,
Currently, to do this, you need to brew your coffee at room temperature whilst simultaneously using a higher ratio of coffee to water, this is because you can’t forcefully access all the flavors of the coffee using heat you need to use more coffee to compensate for the lack of heat.
Now if you were to use heat you would get some of the flavors such as the acids you were trying to avoid.
It is always better to make a stronger brew than weaker one why because it’s easier to fix a strong coffee than a weak one.
That’s because if its too strong you can always just add more water to make it ideal for you.
What Does this High Ratio Of Coffee to Water Mean for You
- Your cold brew coffee is gonna end up costing you more this is because you end up using more coffee than you would normally use for coffee brewed using heat
- This is why cold brew coffee at coffee shops tend to be more expensive than regular coffee
- Your cold brew coffee will usually have more caffeine than regular coffee this is because of the large quantities of coffee used
- Caffeine is a water-soluble particle so it will dissolve in your cold brew it’s just gonna take longer but its gonna have a lot more of it.
- This is why a lot of Gyms offer cold brew as a healthy energy drink.
Why are there So Many Variations on the Ratio
If you do research on cold brew you would go crazy with the various recipes this is because of:
1- Cold Brew Concentrate
One of the biggest reasons why you would see different ratios especially some with a much higher portion of coffee, is that those recipes are to make a cold brew coffee concentrate which is then watered down to the individual preference.
2- Individual Preferences
Some people like really strong coffee and others can only stomach a
The key here is to taste and add water to adjust to
3- Steeping Time and Temperature
How long and what temperature you steep your coffee affects the ratio as well, gonna talk more about that later down in the article so keep on reading.
How Long Should You Let Cold Brew Coffee Steep for
For me when using the ratio of 1:7 the ideal time for leaving your coffee to steep is for 12 to 14 hours at room temperature.
Factors that Affect How Long You Should Leave the Coffee to Steep
Some people leave their cold brew to steep in their fridge and because of this the coffee takes longer to brew my advice is to let it steep at room temperature for the coffee to diffuse faster.
If you do intend to place your coffee and water in the fridge it would probably be best to let it brew for a longer time think 18-20 hours.
Why Does Cold Brew Take Longer in the Fridge
Now if you let your cold brew steep in the fridge this reduces the amount of energy in the water.
The energy in the water is what causes the coffee to diffuse into the water that’s why coffee brewed with heat is so fast, by heating the water it excites the water molecules to release the coffee
Why people place their cold brew coffee in the fridge is
- They are confused by the name ‘Cold Brew’ meaning they think the coffee has to be brewed using the cold
- This is completely false cold brew got its name because
itsserved iced cold not because it was brewed cold.
- Another reason is that a lot of tutorials and recipes available online has instructions to place the coffee to steep in the fridge.
- Not that they are wrong it would brew it’s just it’s gonna take a longer time in the fridge.
- The final reason is that people want to drink their coffee as soon as they filter it meaning they want it cold.
- And I agree, that’s why I usually drink my cold brew with ice.
- So it can steep at room temperature and still be enjoyed after 12-14 hours.
If you use
Now using less coffee but having it steep longer you might get the same results like 1:7 ratio, though you just got be patient for a couple of hours more.
Though of course, this has a limit because if you let your coffee steep too long it could start releasing more acids which is what gives coffee its bitterish taste.
3-Size of the Grounded Coffee
The finer or smaller your coffee bean is grounded the faster it would brew.
This is because the smaller the coffee is the more surface area it has to allow the water to interact with the coffee molecules thus speeding up the diffusion of the coffee.
Though here again, you got to be careful you dont want it to be too fine so that it would start releasing those bitterish acids stored in the beans which we would refer as over-extraction.
Instead, go for a coarse grind that would brew fast without releasing the unwanted acids.
