What is “Bloom Coffee?”

Bloom refers to the process in which gases are released from the coffee when water hits the grounds. It causes the coffee grounds to rise and grow. As soon as the water is added, CO2 from inside the bean is purified and replaced by water for the brewing and extraction process.

Why Should I Use the Bloom Method?

There are many reasons why you might want to try brewing your coffee using the bloom method. For one, it allows you to extract more flavor from your coffee grounds. This is because the bloom method allows the coffee grounds to fully expand and release their flavor before being diluted by more water.

Another reason to try bloom coffee is that it is a great way to make coffee if you use freshly roasted beans. As coffee beans are first roasted, they release an incredible amount of carbon dioxide. This gas can make extracting flavor from the beans difficult if you brew them using traditional methods. 

However, the blooming process allows the carbon dioxide gas to escape before brewing, making it easier to extract all of the delicious coffee flavors from your beans. True coffee aficionados will truly appreciate the difference!

Bloom Coffee is a delicious, refreshing way to start your day.

Simply put, bloom coffee is coffee that has been brewed using the bloom method during the brewing process. Coffee experts created this brewing method to extract the fullest flavor possible from coffee grounds. 

The bloom method involves wetting the coffee grounds with hot water and then allowing them to “bloom” for a minute or two before adding more water and brewing the coffee as usual. This leads to a better coffee experience all around.

How To Bloom Coffee

Have you ever made a pot of coffee, only to have it taste weak and watery? If so, you may not have been blooming your coffee. 

Blooming your coffee is simple. Now that we’ve convinced you to try blooming your coffee, let’s talk about how to do it!

The first thing you’ll need is a good quality coffee grinder for whole beans. This is because fresh coffee grounds will bloom better than pre-ground coffee.

Next, you’ll need to measure the correct amount of ground beans. We recommend using about two tablespoons of coffee per cup of water. Once you have your coffee grounds, it’s time to start blooming!

  • Pour hot water over your grinds, moving outwards from the center (a circular motion works best). 
  • Ensure all the coffee is soaked by adding about twice as much water as the coffee’s weight. 
  • The coffee will create bubbles as the CO2 escapes the water (usually around 30 seconds, but this varies). 
  • By releasing oil and gas, the coffee can develop a richer flavor. You can continue brewing as usual after the blooming period ends.

Can Coffee Bloom Affect Flavor? 

There are two reasons why carbon dioxide bubbles can negatively impact the flavor of your coffee during coffee bloom.

In the first instance, carbon dioxide has a sour taste. This is not ideal, and if you proceed with brewing your coffee during the release of carbon dioxide, you may detect some sourness in the drink.

There is another effect of CO2 degassing as well. Ground coffee beans need to be extracted with hot water to make the most delicious and flavorful cup of coffee. In addition to restricting water’s access to the beans, the carbon dioxide expelled prevents the compounds that give coffee its flavor from being extracted.

Think of it as a busy line at your favorite local coffee shop. Customers can’t place their orders until the barista finishes making coffee for the other customers already in line.

You’ll notice a difference in the flavor profile when the water makes optimal contact with the grounds. Due to the fact that sugar takes longer to dissolve in water than acids, coffee tastes sweeter and more robust when the water has ample time to interact with the grounds. There is a tendency for under-extracted coffee to have a sour taste and to be more acidic.  

How much water does it take to bloom coffee?

Wetting coffee grounds is all that is necessary to bloom them, so you only need a small amount of water to do so. A good guideline is to pour 2–3 grams of water per gram of coffee. A 15-gram serving of coffee would require about 30 grams of water to bloom.

Remember, blooming is just a way to wet the grounds evenly so they’re ready for brewing. You don’t need to soak them or use a lot of water, just enough to get them evenly moistened. It’s the perfect way to get the best flavor!

Various Ways to Bloom Coffee

There are many ways to bloom coffee. You can use a French press, an espresso machine, or even cold brew recipes. Each method has its own unique benefits and drawbacks.

With a French press, you can get a full-bodied cup of coffee with a rich flavor. However, the press can be difficult to clean.

Espresso machines produce a quick, strong cup of coffee with a lot of crema on top. However, they can be expensive and require a lot of practice to use correctly.

Finally, cold brew recipes are perfect for those who want something easy and convenient. You’ll have a smooth and refreshing cup of coffee in the morning (if made overnight).

How To Bloom Coffee With A French Press

Blooming your coffee with a french press is as simple as drizzling a little water over the grounds. After the bloom has stood for about 20 seconds, stir it with a spoon to ensure all the coffee grinds have been incorporated. Once that’s done, you can continue brewing as usual.

 As well as optimizing flavor extraction, blooming prevents bitterness. Be sure to bloom your beans next time you make French Press coffee for the best results.

How To Bloom Coffee With a Manual Espresso Machine

When making espresso with a manual machine, you’ll want to start by blooming your coffee. This technique is known as pre-infusion, and it’s important for ensuring a rich and evenly extracted shot. 

When you’re ready to pre-infuse, just lift your machine’s lever only partly so that water flows freely onto the puck. Activate the pump by lifting the lever after 5-10 seconds of letting the water sit on the coffee. This will help to evenly distribute the water throughout the grounds, resulting in a superior espresso.

How To Bloom Cold Brew Coffee

Since cold-brewed coffee is brewed over a long period of time, it already reduces a good amount of the bitterness that can accompany coffee due to its slow brewing process. There is also a way to make your cold brew coffee more complex and smoother by blooming it as well!

For best results, let the coffee bloom for around a minute, which releases those gases and flavors. Add the remaining water and let your cold brew steep overnight.

As a result, the coffee will be smoother and more flavorful compared to a traditional cold brew recipe. Considering this, it makes sense that brews that work well in pour-overs will also work well here. 

Adding a pinch of acidity to your cold brew through a hot bloom is likely, but it probably won’t even be noticeable to most coffee drinkers. Just keep this in mind if you are trying to avoid high acid levels.

Blooming With an Automatic Drip Coffee Maker

If you’re looking for a quick and easy way to make great-tasting coffee, try blooming your coffee with an automatic drip coffee maker. The best way to bloom your coffee is to add your ground coffee to the filter basket of your coffee maker. 

It is important to add just enough water to soak the grounds without dripping. You should wait approximately 90 seconds before starting your machine’s normal brewing cycle. 

By taking this simple extra step, you’ll ensure that all of the coffee’s flavorful oils are released, resulting in a rich and satisfying cup of java.

Frequently Asked Questions

Can you bloom dark roasts?

Yes.  Since dark roasted coffee has a large amount of surface oils, water can have difficulty fully wetting the coffee bed during brewing. Blooming can help improve flavor.

Coffee bloom occurs at high temperatures at a fast pace. As a general rule of thumb, the water used for brewing must be between 92 and 96 degrees Celsius (or, 197.6-204.8 degrees Fahrenheit.
