Differences in taste depending on coffee extraction method

There are many ways to brew coffee.
The taste changes depending on the extraction method, so even if the brand is the same, you can enjoy different expressions just by changing the extraction method.

The deep and fun part of coffee is that you can enjoy it in many different ways depending on the combination.

In today's article, I would like to tell you about the differences in taste depending on the extraction method.

Two extraction methods

There are two main ways to extract coffee.
They are "transmission type" and "immersion type".

The "transmission method" is a method of extracting coffee by passing it through hot water.
Typical methods are hand drip (paper, flannel) and espresso.

The ``immersion method'' is a method of extracting coffee by soaking coffee grounds in hot water.
Common examples include the French press and siphon.

paper drip taste

This method involves pouring hot water into coffee and filtering it through the hot water using a paper filter to extract the coffee ingredients.
Because it is strained through a paper filter, fine powder and oil are not extracted, making it easier to get a clean and clear taste.

In addition, there are various types of paper drippers, and the extraction speed etc. differ depending on the dripper used, so the same paper drip can produce a variety of different tastes.
 

Flavor of flannel drip

The extraction mechanism is the same as paper drip, but instead of a paper filter, a cloth filter (flannel) with a coarser mesh than paper is used.
Therefore, it tends to give a heavier impression than paper filters.

Nell drip, which was developed in Japan, has been developed as a technique for making dark roasts more delicious, and by allowing some of the oil that is unique to dark roasts to pass through, it is a way to enjoy the depth of flavor that is unique to flan drip.
 

espresso taste

A special brewing machine is used to extract coffee in a short time by applying high pressure (about 9 atmospheres).

Each cup has a very small extraction volume of 25-30ml, producing concentrated coffee with a distinct flavor and rich mouthfeel.

It was common to use dark-roasted brands, but with the third wave, the number of shops that are brewing espresso with light-roasted brands has increased.
 

french press taste

Pour hot water over the coffee powder and let it steep until thoroughly soaked.

Because the coffee is filtered through a slightly coarse stainless steel filter, fine powder and oil are mixed into the coffee liquid.
This makes the coffee richer and heavier on the tongue.

This is an extraction method that allows you to directly enjoy the aroma and taste of the brand.
 

taste of siphon

This method boils water in a flask and uses changes in atmospheric pressure to move the hot water and extract coffee.

Because the coffee grounds and hot water are soaked in the funnel for a certain period of time, it is said that the flavor does not change easily.

It has a bitter taste because it is brewed with boiling water, but because it is strained through a paper filter, fine powder and oil are less likely to mix in, and the result tends to be clearer than a French press.
 

Summary

Paper filter <br />Refreshing and clear taste, with a wide variety of drippers available

Nell drip <br />The rich taste of dark roasting

Espresso <br />Outstanding flavor and rich mouthfeel

French Press <br />You can directly enjoy the taste of the brand, including the body, richness, and coffee oil.

siphon
Bitterness and clear feeling, stable extraction method



What did you think?
Even with the same brand, you can enjoy different flavors by changing the extraction method.
