| Boilerpipe Text | Cold brew coffee is hands-down the easiest way to make coffee: all you need is water, beans and a bit of patience!
These days you can find dedicated devices such as the
Toddy
or the
Hario Mizudashi
cold brewers. However, you don’t have to have any of those to make coffee using this method; all you need is a container (glass preferred) and a filtering device (like a V60, Chemex, AeroPress or even a French Press).
Here’s our step-by-step guide (or jump onto this guide’s
FAQs

Gear

kg (L) of cold/room-temperature water ♨︎
•
Extra water to rinse any paper filters
ℹ︎:
If you don’t have a grinder, that’s OK! You can always use pre-ground coffee, though we recommend freshly ground because it does elevate the flavour of each brew.
♨︎:
In our recipes, we measure water in grams because we use scales, and it’s easy to achieve precision this way. However, if you don’t have scales, the conversion is easy: 1g=1mL.
Method
Get your gear ready.
If you’re using a jar or standard container, it’ll need to be larger than the amount of coffee you want to end up with. We also recommend it can be covered, so the brew doesn’t absorb any smells in the fridge or room.
Grind
83g of coffee
(for 1 litre)
or
250g of coffee
(for 3 litres)
.
For cold brew, we always use a 1:12 ratio (i.e. 1g coffee = 12g water). The grind size should be similar to that for pour-over or filter, about the same as coarse sand.
Combine the grounds with
1 Litre
or
3 Litres
of water and mix gently.
Water can be straight off the tap/filtering device. Give it a good stir so all the coffee is wet.
Wait.
You can leave it to brew at room temperature, but we recommend the fridge for about 8-11 hours. You can also experiment to find the length you prefer.
Filter out the grounds.
If you’ve got a Chemex or Hario V60 filter, pour the liquid through that to filter out the grounds (don’t forget to rinse it with boiling water beforehand). Pour slowly, and replace the filter paper if it gets too full.
Add ice cubes and/or m*lk, and enjoy!
Store your cold brew in a bottle or closed container in the fridge. It’ll keep for 5-10 days depending on the freshness of the beans.
Tips & notes
Scale it up or down using a 1:12 ratio.
This cold brew coffee recipe scales up and down easily, as long as you stick with the ratio of 1:12 (coffee to water). No matter how much you’re brewing, the wait time is still the same: around 8-11 hours inside the fridge.
This ratio accounts for added water from the added ice cubes.
The result is a brew that sits on the
stronger
side, which mellows a bit once there’s some added water melting from the ice cubes. If you prefer to avoid this, increase the coffee ratio or make cold-brew ice cubes beforehand (or drink it without any ice at all).
Add m*lk to your cold brew.
Top up your coffee with a dash of cow or alternative milk. This dulls the flavour in lightly-roasted single origins, so we recommend using an espresso blend (like Pacemaker) or our decaf if you like your cold brew like so.
Go beyond.
Cold brew is also perfect to start combining to make other drinks and cocktails. Dilute with sparkling water for a refreshing cold brew spritz or use as a base for an easy espresso martini variant.
Frequently Asked Questions
What is cold brew coffee and how is it different from iced coffee?
Cold brew coffee is made by steeping coarse-ground coffee beans in cold water for 8–12 hours,
producing a smooth, low-acidity coffee concentrate (when the coffee is good!). Iced coffee is brewed hot and then chilled or poured over ice, giving it a high brightness and acidity flavour profile.
What is the best coffee-to-water ratio for cold brew?
A standard cold brew coffee ratio is 1:12 by weight – that’s 1 part coffee to 12 parts water.
For example, 83g of coffee to 1L (equals 1kg) of water. Adjust the ratio to make it stronger or lighter
to suit your taste.
How long should I steep cold brew coffee?
Steep your cold brew for 8 to 11 hours at room temperature or in the fridge. Shorter steeping
produces a lighter, tea-like flavour, while longer steeping yields a richer, bolder taste.
What grind size should I use for cold brew coffee?
Use a coarse grind, similar in texture to raw sugar or sea salt. Finer grinds can cause over-extraction
and a muddy texture, while too coarse may make your brew weak.
How coarse should the grind be exactly?
Aim for particles about 0.8–1.2 mm in size—roughly the texture of raw sugar crystals.
If you have a burr grinder, choose a coarse or French press setting. Consistent particle size
is key to even extraction. For a visual reference, check our
grind size visual guide
.
How long does cold brew coffee last in the fridge?
Cold brew concentrate will stay fresh for up to 10 days in a sealed container in the fridge,
but for the best flavour, drink it within 5 days. Store in an airtight bottle to maintain freshness (glass or metal preferred).
Can I make cold brew coffee without special equipment?
Yes. You can brew cold brew in any clean jar or pitcher and strain it through a fine-mesh sieve,
cheesecloth, or paper coffee filter. A dedicated cold brew maker makes the process easier, but isn’t required.
Can you brew with hot water first (“Japanese-style iced coffee”)?
Yes, but it’s a different method entirely. Japanese-style iced coffee brews hot coffee directly
over ice, locking in aroma and brightness. Cold brew, on the other hand, uses only cold water,
resulting in a smoother, less acidic profile. If you prefer a vibrant, tea-like cup, try the
Japanese method.
What type of coffee and roast works best for cold brew?
We like our cold brew with delicate single origins. You can look for coffees that have a medium/light roast profile, or we certainly recommend any of our seasonal single origins in our
coffee shop
. Oh, but if you have it with milk, you can try making espresso blend cold brew and then add your choice of cow or nut milk.
What dedicated gear do you recommend for cold brew?
We recommend the
Hario Mizudashi Cold Brew Pot
for ease and
affordability, or the
Toddy Cold Brew System
for larger batches.
For grinding, a
burr grinder
will give you a consistent coarse grind.
