Coffee Bloom: Smell the Science Behind it

As you pour hot water to your coffee grounds, you'll see how coffee blooms immediately.

In the complex world of coffee making, details like the way you serve it to the machines involved, give a different result in your cup. To master your skills and knowledge in coffee, we provide you a term that’s an essential part of brewing: coffee bloom. But what does that mean? Pour hot water over your coffee grounds, and you’ll see it yourself.

The bloom

To talk about coffee bloom, we must mention the coffee beans and the roasting process they follow. During the roasting of the beans, they absorb large amounts of CO2 inside. That compound stays until coffee is exposed to hot water, which is when the gas is released.

As you pour the hot water, you might notice some resistance in the grounds. This happens due to the gasses resisting against the water and making your coffee to expand. When adding the water you must be very careful not to pour excessive amounts of water, but minimal quantities in a circular way. Done properly, the CO2 will be released smoothly.

Is it necessary to bloom your coffee?

It’s actually mandatory. All the flavor is inside the beans, as well as the CO2, so it is necessary that both are released and absorbed by the water in order to obtain the results you want. Water must be in perfect balance, so when coffee blooms, the gas is released, and the beans absorb the water fully.

Unless you’re doing cold brews, it is necessary to bloom your grounds properly by measuring the hot water. With little water, you’ll get weaker results, whereas too much water will cause the flavor to dilute. Proportion is as important as blooming, for that matter.

This process isn’t that complicated to carry out, but it takes time to master. Extracting the flavor out of the grounds is essential, so it must be done with skill and proper measurements. Consider all these factors the next time you brew.
