How to preserve coffee and cooked beans? Will the sealed exhaust of coffee beans explode? Storage mode of coffee beans

Fresh coffee tastes best. So how do you take steps at home to make sure your coffee stays this way?

Why is coffee storage important?

Potatoes are in the dark, dry cupboard, while cheese is in the fridge. There are many well-known rules about how to keep the family's favorite food fresh.

This is exactly the same as our favorite morning drink, coffee. If the storage is incorrect, it will not be at its best. Ireland-based 2019 World Cup champion Daniel Hobart (Daniel Hobart) said: "Coffee... It's out of date, but that doesn't mean you'll get sick. "

Although this is good news, using old coffee is not the best choice. Coffee is a kind of food, and like all foods, it reacts with oxygen and becomes obsolete over time. Daniel told me: "it will lose its freshness, flavor and aroma."

The flavor and aroma make the coffee delicious. So, when these are reduced by exposure to oxygen, you get a cup that is less energetic and tastes less. However, when properly stored, it can help protect the freshness of the coffee and make the coffee taste longer.

How to store coffee at home

We have summarized all the steps to ensure that you store coffee in the best way at home.

1. Check the baking date

You will not buy outdated food, so make sure you check the roasting date of your coffee. This is the first step in making your coffee fresher at home.

Daniel told me, "you are strongly advised to drink as much fresh coffee as possible." With the passage of time, coffee will lose its flavor and aroma, so you will have a better chance to make a cup of coffee with fresh coffee beans.

"but remember, coffee also needs to be degassed, so you need to roast it until four to seven days after it is degassed," says Daniel. During the baking process, different gases, including carbon dioxide, are formed inside the beans. After baking, this carbon dioxide continues to be released from the beans, a process called degassing.

If you are brewing filtered coffee, you can use it a few days after baking. If you want to make espresso, it is recommended to wait at least 7 days. Otherwise, the gas in the beans will prevent the water from entering and interrupt the extraction, resulting in an old, flat flavor.

So, until when should I have coffee? "Coffee should be delicious for up to a month after baking," Daniel told me. That doesn't mean you can't drink coffee a month from the baking date. This is not recommended if you want to get the best taste from coffee.

two。 Reduce exposure to oxygen

Contact with air, especially oxygen, can make coffee obsolete faster. Therefore, reducing this connection is an easy way to improve the storage of coffee at home.

How can you do this at home? NisanA coffee ca, Turkish barista champion in 2016, 2017 and 2019, told me: "if there is a self-sealed bag, I usually put the coffee in the original package. Otherwise, I will change it to another package. "

Self-sealing bags help prevent oxygen from entering the bag. If you want to use a zipper to keep the coffee in the original bag or transfer the coffee to another bag, try to vent as much air from the bag as possible before closing it. In this way, the remaining air in the bag will react with the coffee.

Daniel also recommends using vacuum packaging machines for vacuum packaging of coffee. These completely remove the air from the bag, and almost no air enters the inside. Similarly, vacuum cans can be purchased online, including filling coffee cans, tightening the lid and using buttons to remove internal air. Remember, coffee should be kept in an opaque container to prevent sunlight from reacting with coffee beans.

3. Store the coffee in the right place

Moisture, light and calories all make coffee stale. Therefore, coffee needs to be stored in a cool, dry and dark place.

If there is, this could be a cupboard or kitchen. Note that ideally, the space should be away from heat sources, such as ovens.

"I separate coffee from spices or anything that smells bad, because coffee is so powerful when absorbing aroma," Nisan told me. " Coffee is hygroscopic, which means it absorbs all substances in the environment, including oxygen, aroma and moisture. It is best to keep it away from any food with a strong smell, or from an environment with a peculiar smell.

4. Buy less coffee and grind it yourself.

When buying coffee, you can do some things that can increase the amount of coffee you store at home, thereby increasing the freshness of the coffee.

You can also increase the storage of coffee according to the type and amount of coffee you buy.

Whole beans are better than pre-ground coffee, which ages faster. Grinding increases the surface area of beans, thus speeding up the reaction of oxygen with them. Daniel said: "if you want to keep your coffee for as long as possible, you should buy whole beans and grind them fresh."

Buying larger bags of coffee also means that fresh coffee will no longer be used for a longer period of time, which may make it obsolete. Eric Squires (Eric Squires), who used to manage triple crown coffee in Indiana, told me, "keep only a small amount of consumables on hand each week."

If you can't get smaller bags more regularly, it's best to follow the rules of putting coffee in a cool, dry and dark place and grinding it yourself if possible.

Storage Coffee Myth: debunking

You may see different tips and tricks on how to keep coffee fresh, but not all of them are completely correct. We have debunked some myths about storing coffee, so you can be sure that your coffee is as fresh as possible.

Put coffee in the fridge:

Coffee is porous and absorbs aroma and smell. The refrigerator is full of all kinds of food and gives off different smells. Eric told me that "storing it in the refrigerator makes coffee look like baking soda" because it absorbs the smell around it.

There is still a lot of moisture in the refrigerator, which can cause coffee to become obsolete more quickly because coffee beans react with moisture.

Put the coffee in the fridge

Daniel explained that you can put the coffee in the refrigerator. But, he said, "it's very important to vacuum pack the coffee and freeze it." Do not let the air come into contact with the coffee, because this will cause the coffee to absorb odor and moisture.

Coffee should not be stored directly in the refrigerator. If you do not draw air from the bag, the coffee risks absorbing high moisture and emitting a potential smell from the refrigerator.

Storing coffee at home is simple and effective, and if you do it right, it means you can get the most out of the coffee you buy. It is important to remember that coffee is a food and treat it like any other grocery to ensure that it is kept fresh and fully enjoyed.
