Coffee is a beverage that many people love. It’s comforting, it wakes you up, and there are so many different kinds of coffee to drink like espresso, iced coffee, and more. But have you ever heard about the process behind your favorite caffeine-filled drink?
There’s actually something called “coffee bloom” which is when water hits roasted coffee beans. This causes the release of carbon dioxide gas and causes those delicious coffee aromas to escape.
In this article, we’re going to discuss why coffee blooms and what can cause it to happen.
So, What Is It?
Coffee “bloom” or coffee “blooming” is when water comes in contact with roasted coffee beans, causing them to release carbon dioxide gas. This is what causes those delicious aromas of coffee to escape as they’re trapped in the bean and the water allows this gas (and the delicious smells) out into the world.
What Causes Coffee to "Bloom"?
There are several reasons why coffee bloom happens in a cup of coffee:
When the water hits the beans, it’s basically opening them up and releasing those delicious aromas into the air.
The warmer the water is, the more carbon dioxide gas is released. This means that when you make your own iced coffee at home, using cold water isn’t the best idea if you want it to be more aromatic.
Coffee bloom is another way for coffee to release its CO2. You don’t want your cup of joe to be flat and not full of foam, so the blooming process makes this happen naturally.
Coffee is made up mostly of water by weight, so it makes sense that the more hot water is introduced to the beans, the more gas will come out.
What Are The Effects of Coffee "Blooming"?
The effects of coffee bloom are that the water in your cup is more flavorful and aromatic. More foam means more aromas for you to enjoy as well!
You may have a bean that has been losing its flavor over time, but when bloomed it will give off those rich aromas and oils once again.
How To "Bloom" Your Beans Properly
With The Pour Over Method
To experience the coffee bloom using the pour-over method, all you need is a cone-shaped dripper, filter, kettle of hot water, a cup and your favorite beans. The method is simple and straightforward:
Heat up the kettle of water. When it starts to boil, pour the water over the beans, into the cone-shaped dripper. The water will first go over the grounds before dripping into the cup.
The coffee should bloom within 15-20 seconds. Experiment with different types of beans and find what works for you!

The French Press Method
The process is as follows:
Put the coarse-ground coffee into your French press, then slowly pour the water onto the coffee. The bloom should happen within 15-20 seconds after pouring water on your grounds.
Does blooming coffee make a difference?
Yes, blooming makes a huge difference in the flavor and aromaticness of your drink. Blooming coffee helps release CO2 gas from the beans and infuses more water for a better-tasting cup of coffee.
How long do you let the coffee bloom?
You should let your coffee bloom for 15-20 seconds after pouring hot water on it. This is just enough time to allow the gas contained in the beans to escape. If you let it bloom for too long, your coffee would be bitter and acidic. If you do not let it bloom properly, you will miss out on all of those delicious aromas and flavors!
Is blooming coffee necessary?
Blooming coffee is indeed necessary to make a good cup of brew. There are several ways to bloom while using different methods such as the french press and pour-over. You can try this method with your own variations to find what works best for you!
