Can you make great coffee with fresh beans?

Original title: Can you make delicious coffee with fresh beans?

Does fresh coffee make the best coffee? This is a common misconception.

People who know about coffee may know that coffee is also a kind of food ingredient. Many people mistakenly believe that the fresher the coffee beans, the better. Generally speaking, we still think that the fresher the coffee beans, the better. However, it does not mean that it is best to brew the coffee beans immediately after they are roasted.

Roasted coffee beans contain many volatile aromatic substances. The longer they are stored, the more these aromas evaporate. Therefore, the fresher the coffee is, the better. For coffee brewing, the coffee cannot be too fresh.

Most coffees take 2-3 days to complete the exhaust process, expelling the gas that enters the coffee beans during the roasting process. We call this process "bean nurturing". Only after the "bean nurturing" is completed, the coffee beans will reach the peak state with the fullest aroma and flavor.

Fresh coffee beans need to be properly stored, but for coffee novices, what kind of coffee beans are fresh?

Coffee can be drunk all year round, but not all coffee beans are fresh. There are about 53 coffee producing countries in the world, and the annual coffee output is very large, so a lot of coffee beans from previous years are stored. However, fresh coffee beans, like rice, have their seasonal production periods. There are also seasonal and out-of-season coffee beans. Generally speaking, coffee beans will not lose too much coffee flavor within two or three years if stored in a proper environment. The quality of seasonal coffee beans is relatively high. Understanding the harvest season of coffee beans is also one of the ways to choose fresh coffee beans.

In addition, freshly ground coffee does not mean fresh coffee.

The most common way to see this is when brewing coffee, such as whether the ground coffee powder has enough bubbles. Generally, the fresher the coffee beans, the richer the bubbles; for the same coffee beans, dark roasted ones have richer bubbles than light roasted ones.

During extraction, the richness of bubbles is positively correlated with freshness. The fresher the beans, the more bubbles they produce. This is because the beans contain a lot of gas and have a strong respiration. During extraction, the gas in the beans is released, and what we see are beautiful and full bubbles. There is a very vivid adjective, "release". Yes, when fresh coffee beans are extracted, clusters of rich bubbles are like flowers of this season, blooming. However, there is a premise here, for the same coffee bean. To be precise, it is the same raw beans, the same roasting, and the same operation. The richness of bubbles will vary between different coffee beans, or between different roasting degrees of the same coffee bean, or between different operating coefficients of the same coffee bean.

How to store coffee beans:

1. Use upright sealed cans: The carbon dioxide released by fresh coffee beans will be retained at the bottom of the container, forming an antioxidant layer to protect the coffee beans; and the container should be placed upright to prevent the carbon dioxide in the can or bag from escaping. It can be seen that upright, tall and thin containers with openings facing upward are more suitable for protecting coffee beans.

2. Use a long spoon to scoop out coffee beans: Carbon dioxide has a higher specific gravity than air, so it will settle at the bottom of the container. When taking out coffee beans, remember to pour them out, otherwise the carbon dioxide in the container will be poured out, and regeneration will inevitably become more and more difficult. It is recommended that you use a long spoon to reach the bottom of the container to scoop out the beans, so as not to cause the carbon dioxide to be lost quickly.

3. Use opaque jars: Light is a crude medium for oxidation, and opaque jars can slow down the rate of oxidation.

Use vacuum jars: There are more and more vacuum jars on the market, and the price is quite cheap. These jars are equipped with a mechanism that can be pulled or pressed to extract all the air in the jar to form a vacuum state. The vacuum state means there is no oxygen and moisture, which is a good place to store coffee beans.

4. Place in a cool and dry place: High temperature can easily evaporate the aroma of coffee and the excellent substances inside the coffee beans. Therefore, the coffee can should be kept away from high temperature environments as much as possible, and it is best to place it in a cool and dry place.

In general, the types and shelf life of fresh coffee beans are as follows:

* Unroasted green coffee beans 1-2 years

* Roasted coffee beans (for espresso) for about 3 weeks

* Roasted coffee beans (other than Espresso) 30-45 days

* Ground coffee beans: 5-10 minutes
