Making the Perfect Pour Over Coffee

Making pour-over coffee is a straightforward procedure once you get used to it, but it requires time. Read our instructions below to learn how you can make perfect cups of pour-over coffee with ease!

Step 1: Preparation

Boil your brewing water first and pour it into a preheated kettle. If you have a gooseneck kettle, then that would be best. Then put the paper coffee filter inside your preferred brewer (i.e., a Hario V60) and rinse it with some of that hot water.

Step 2: Weighing and grinding

Now, measure out the coffee beans and grind them. It’d be ideal if you could use medium-dark roasted and single-origin beans for your pour over brewing. In terms of grind level, coarse (medium to medium-fine) grind is ideal for a pour-over. You should use a 1:17 coffee to water ratio for your regular strength pour-over. Use a 1:15 ratio for a stronger brew.

Step 3: Blooming the Grinds

Saturate all the coffee grounds with as little water as you can. Wait for 30 seconds to settle into the blooming phase. This “pre-infusing” starts the extraction process by releasing gases and oils.

Step 4: Making The Coffee

Pour the hot water again through the filter very slowly. Let the water reach halfway up the filter cone. Once the foam forms on top of the coffee grounds, pour in the rest of the hot water to complete the brewing. Keep the water level high and don’t leave any grounds high and dry!

Finally, wait until the pouring stream turns into drips. After that, only pour the and enjoy!


What is the pour-over coffee’s golden ratio?

It’s a 1:17 coffee-to-water ratio. For a stronger brew, follow the 1:15 ratio.

How much coffee do you put in a 16-ounce pour-over?

With the 1:16 ratio, for every 16 oz. of water, you should put 1 oz. of coffee.

How do you make 2 cups of pour-over coffee?

Two cups of pour-over require 10 oz. of water and about 0.7 oz. of coffee grinds.

Why is my pour-over coffee weak?

Weak pour-over happens mainly because of using coarser grinds. So use moderately coarse grinds for your pour-over.

What is the ideal pour-over coffee temperature?

Maintain a temperature of 195 to 205 degrees Fahrenheit if you want a perfectly flavored and bitter-free pour-over brew.

Final Words

To make it a perfect cup of coffee, you always need to maintain the water and coffee ratio.

But, pour over brewing method is different than others. You are not boiling, pressurizing, or mixing coffee and water. Instead, simply add water to coffee grounds and filter them.

So, for ‘Your’ perfect taste, you should do some experiments and find out your best coffee to water ratio for pour over and others also, like a French press.

Enjoy Your Coffee!!!
