Cold Brew Coffee Ratio Calculator

Is your cold brew coffee off-tasting and you’re not sure why? You’re probably not measuring your coffee correctly. But how can you determine the ideal coffee-to-water ratio? Keep an eye on this site to figure out.

What exactly is the coffee ratio?!

Much like every meal needs a recipe, so does coffee. The coffee ratio is the recipe for how many parts water to how many parts coffee to make the perfect cup. This magic number can be adjusted to fit each individual’s taste, making everyone’s cup just their style.

To find the coffee ratio, start by measuring out how much water you will be using. Then, measure out how much coffee you will be using. For every cup of water, use two tablespoons of coffee. If you want a stronger or weaker cup of Joe, adjust the ratio accordingly.

For example:

With a 1:17 ratio, use 17 grams of water for every 1 gram of coffee. If you don’t have a scale, use a 1:4 ratio of tablespoons to ounces to measure coffee or water. 1 tablespoon coffee per 4 ounces of water etc…

We designed a tool to help you because most people use a normal drip coffee machine and aren’t good at coffee math.

Simply tell us how many cups of coffee you want to brew and what you’ll be measuring with.

Why Is Measurement Important?

It is critical to learn the habit of correct measuring in order to prepare a balanced cup of coffee each time. By measuring your coffee to water ratio, you will have all the facts you need to make a consistently tasty cup of coffee, just the way you like it. 

There is no alternative for a small food scale that measures in grams for this purpose. It may be used to measure water, beans, and ground coffee.

Use this calculator to determine how much water and coffee you’ll have to prepare for a cup, or scroll down for a quick explanation of the ratios.

Common Cold Brew Questions!

What is Special About Cold Brew Coffee?

It is less acidic. Cold brew coffee is more than 67 percent less acidic compared to hot brewed coffee. It’s sweeter and softer because coffee grounds aren’t exposed to high temperatures, cold brew coffee is generally more delicious and less harsh.

Is Cold Brew Stronger Than Regular Coffee?

Cold brew coffee is often brewed with a greater coffee to water ratio of two to two – and – a – half times greater which means it is sharper than coffee produced with a more traditional coffee to water ratio.

Can I Warm Up Cold Brew Coffee?

Yes, cold brew coffee may be heated, because it is typically concentrated, pouring hot water just warms it up and waters down the concentrate to make it more like a standard cup of coffee. You may change the amount of hot water you use to customize the intensity of your hot coffee.

Do you need a Specific Coffee For Cold Brew?

Begin with a high-quality coffee bean to produce the greatest cold brew. A thick grind fits brilliantly and helps filtration. Instead of buying pre-ground coffee, buy whole beans and grind them yourself. Keep in mind, you’re drinking coffee in its purest state so investing in the beans is worthwhile.

Let’s Solve A Coffee… Math Problem!

If 90 gr of Ground coffee matches with 500 ml of water, how many grams should be the Whole Coffee Beans?

Our suggested water to coffee beans ratio is 500 g (or milliliters) of water to 100 g of whole coffee beans. Try experimenting, but this yields the most socially agreed coffee volume. Just remember, it’s your own taste that matters!

The Coffee-to-Water Ratio: Described

The ground coffee to water ratio changes widely depending on brew technique and personal preference. This blog’s ratios are based on a combination of popular and professional data.

But there is no wrong way—as long as you love your coffee and don’t drink too much of it!

Siphon Coffee Cold Brew to Water Ratio – 16:1

We recommend 15 g of coffee per 250 grams of water. 1.6 – 2.0 grams of coffee per fluid ounce of water.

Moka Pot Cold Brew Coffee To Water Ratio – 1:10

We suggest the 1:10 ratio using a Moka Pot with a 200ml water capacity. This makes roughly two tiny cups of excellent coffee.

Select the appropriate size moka pot!

Remember that you can’t half-fill a Moka pot, so don’t buy 6-cup thinking you’ll just use it for 3-cups every now and again. They only function properly when properly filled.

It really depends also on the types of Moka Pot, so make a wise choice!

Filter Coffees – Water Ratio

In general, soaking coffee (such as the French press, AeroPress, or coffee pouring) requires a coarse grind and a lengthier brew duration.

There is some variation in appropriate grind amounts and brew periods for drip or pour over. Immersion and drip need far more water and significantly more coffee!

For instance, you may see 1:15 or 1:18. You’ll want less coffee with immersion than with pour over.

French Press Cold Brew Coffee To Water Ratio — 1:12

Although there is no one-size-fits-all coffee-to-water ratio for a French press, 1:12 appears to be a common choice. 

Chemex Cold Brew Coffee To Water Ratio — 1:17

Place one rounded spoonful of coffee per 5 oz cup into the filter cone of the Chemex. This is essentially a one-to-one ratio, but most people believe it is too intense. Many great baristas have employed a ratio of 1:14 to 1:17.

Aeropress Coffee Cold Brew To Water Ratio — 1:16

The 1:16 ratio is based on Alan Adler’s initial formula who invented the Aeropress. This brew ratio yields a concentration, similar to espresso, to which you may add hot water or milk to taste.

V60 Cold Brew Coffee To Water Ratio – 3:50

For one full cup, we propose a 3:50 ratio of 15g coffee to 250g water.

The Role of Brew Ratio in Coffee Making – Tips

The coffee grounds to water ratio is vital no matter what type of coffee you’re preparing, notably if you’re preparing many cups.

Learning how much water to use in connection with the proper measurement of grounds produces a wonderful brewing taste at any quantity.

How Do I Pour The Water?

Your coffee brew ratio is vital, but you really should also examine the type of water, grind type, temperature, and how you pour the water… There are several factors.

If your coffee’s taste isn’t right, try adjusting one factor at a time while leaving everything else steady. The grind size is the simplest to begin with.

Grind thinner if your coffee is acidic, salty, or lacks body. This increases the contact surface, which speeds up extracting and allows you to consume more of those delicious coffee flavors in the cup.

If your coffee is excessively bitter, go coarser. This limits the contact surface, slowing extraction and avoiding too much unpleasantness from infiltrating the brew.

Diverse Brew Methods, Varied Brew Ratios

Assume you have a high-quality, specialty coffee that is well roasted to emphasize its greatest qualities, such as its flowery scent or red apple tastes, its balanced body, or caramel sweetness.

So, how would you go about brewing it?

You have several options: filter coffees are the perfect way for many individuals to appreciate the complexities of their coffee. The tastes are clean with a long and more diluted sip.

 An espresso, on the other hand, is a quicker, more powerful beverage that specializes at highlighting 2 or 3 main tastes. This results in a different perfect brew ratio, grind size, extracting duration, and other factors.

Can The Flavor Change Based On Water Ratio?

The flavor of coffee varies based on the formula. Yes, the recipe for making coffee is similar to preparing a cake. It is important to use the correct quantity of each item. You may change the flavor, consistency, and other properties of coffee simply by adding or subtracting water or coffee.

That’s why many baristas and coffee enthusiasts brew with scales and timers like me!
