What is coffee bloom and why it matters

Coffee bloom is the release of carbon dioxide (CO2) that happens when hot water touches freshly roasted coffee grounds. The coffee grounds swell and bubble up as the gas escapes. The bloom affects the flavor profile of the coffee.

Coffee bloom happens with freshly roasted coffee. Full bloom coffee means that youre going to get plenty of gas and smell coming out of the bean when you add water after using a grinder. If theres not much gas in the coffee it suggests that it is actually pretty stale. Freshness is one of the factors that comes into play when you are making coffee, but it is almost always much nicer to enjoy fresh coffee.

Coffee bloom also matters because it allows the water to extract more flavor compounds from the coffee grounds. If you skip the blooming stage or do it incorrectly, you might end up with under-extracted or over-extracted coffee, which can taste sour or bitter respectively. Blooming your coffee properly can help you achieve a balanced and delicious brew.

Coffee Bloom: The Science Behind It

The blooming process is caused by the presence of carbon dioxide in the coffee beans. Carbon dioxide is a natural by-product of the roasting process. Depending on the kind of roast you have, the levels of carbon dioxide will vary but its there.

How carbon dioxide affects the flavor of coffee

Carbon dioxide is slowly released from coffee beans after theyre roasted. This is through a process called degassing. Once you grind the coffee beans, the gas is released much faster thanks to the extra surface area and exposure to air. When you pour hot water onto the grounds, the remaining carbon dioxide is expelled out very quickly in a process known as turbulence.

The big issue caused by turbulence is that the rapidly escaping carbon dioxide essentially blocks water from actually reaching the coffee grounds and drawing out the flavor compounds. Youll also notice that as you pour hot water, the coffee bubbles up and a lot of the coffee grounds rise up with the expanding, releasing gas. Effectively, this means that part of your brewing time is lost in the carbon dioxide escaping. So the time that water could have been interacting with the coffee grounds is instead spent by carbon dioxide preventing the water from fully reaching all the coffee grounds to begin with!

Carbon dioxide is not only responsible for blooming your coffee, but also for adding some acidity and aroma to your cup. Some carbon dioxide is desirable for enhancing certain flavors in your coffee, especially for light and medium roasts. However, too much carbon dioxide can also make your coffee taste sour and metallic. Therefore, it is important to find the right balance between retaining and releasing carbon dioxide in your coffee beans.

Coffee Bloom: The Art of Doing It Right

Now that you know the science behind coffee bloom, how can you use it to your advantage and make a better cup of coffee? The answer is to bloom your coffee properly before brewing it. Blooming your coffee means pre-wetting the grounds with a small amount of water to let the carbon dioxide escape. This way, you can ensure that the water will have full contact with the grounds and extract the optimal amount of flavor.

How to bloom your coffee properly for different brewing methods

The blooming process is slightly different depending on the brewing method you use. Here are some general guidelines for blooming your coffee with some of the most popular methods:


Pour-over is a manual brewing method that involves pouring hot water over a filter cone filled with coffee grounds. To bloom your coffee with pour-over, follow these steps:

  • Grind your coffee beans to a medium-fine consistency and place them in the filter cone.

  • Heat your water to about 200F (93C) and rinse the filter with some water to remove any paper taste and preheat the cone.

  • Pour enough water to wet all the grounds, about twice the weight of the coffee. For example, if you use 20 grams of coffee, pour 40 grams of water.

  • Let the coffee bloom for about 30 seconds, or until you see the bubbles stop forming.

  • Continue pouring the rest of the water in a circular motion, starting from the center and moving outward. The total brewing time should be about 3 minutes.
