In the past, I liked coffee, but now I begin to know how to drink coffee. Did you have the right coffee? Today, the editor will tell you some common sense of coffee that you have to know!

Tip 1-one-way exhaust valve, not incense hole

Hey, have you all had the experience that when you buy coffee beans in stores or supermarkets, you can't help but squeeze the packaging with your hands, then suck into the hole in the packaging and say, "Wow-- this coffee smells good"? The editor would like to remind you that this is a wrong demonstration and will affect the flavor of coffee beans.

The one-way exhaust valve allows the gas in the bag to go out but not in, and the carbon dioxide emitted from the roasted coffee beans will squeeze out the air and slow down the oxidation of the coffee beans. So next time, don't use the one-way exhaust valve as an incense hole and strangle the beans inside.

Tip 2-would you like your coffee beans in the fridge?

Where do all the coffee beans that people buy home or haven't finished yet live? Who has coffee beans that live in the refrigerator? If you still live in the refrigerator, I would like to remind you to help Doudou move to a new home as soon as possible.

Coffee is afraid of moisture, oxygen, light and heat. When stored in the refrigerator, condensate will be produced because of the excessive temperature difference, and it is easy to absorb the miscellaneous smell of the refrigerator and destroy the flavor of the coffee. Therefore, it is recommended that after opening, seal the unfinished coffee beans directly in a coffee bag or sealed can, put them in a cool and dry place at home, and finish them as soon as possible within a month.

Tip 3-have you ever had fresh coffee? How long can I keep the coffee beans?

Generally speaking, food products will look at the shelf life and taste period. Coffee beans belong to the food category. Some large coffee factories use central roasting to mass-produce coffee beans. The preservation period is usually between 12 and 18 months. But the preservation period and freshness are two different things. Coffee beans actually depend on the taste period. The fresher the coffee beans are, the better the coffee is.

After the coffee beans are unsealed, it is recommended to drink them within a month. And the best way to taste is to "grind as much as you drink", because once the coffee beans are ground into powder, their flavor and taste will decay quickly. So, the best way to save it is to... Drink quickly into your stomach!

Tip 4-Why do I have heart palpitations and can't sleep when I drink coffee?

In addition to having something to do with personal physique, caffeine content has a lot to do with the variety of coffee beans. Generally speaking, the cost and price of robusta beans is lower than that of Arabica beans, so most canned coffee on the market will choose or mix them, but people who are worried about excessive caffeine should pay attention-Robota beans are cheap, but they contain three times as much caffeine as Arabica beans.

So people who are worried that they will not be able to sleep and have heart palpitations will not only choose coffee with high quality Arabica beans, but also kindly remind you that coffee powder will extract too much caffeine if it is soaked in water for too long and too fine.

Tip 5-how many beans does it take to make a cup of coffee?

The most objective way is to use scales. Provide a little secret of delicious coffee: 15 grams of coffee powder with 225 grams of water, and then make some adjustments according to your taste. Another tip: lightly roasted coffee can put a little more water, on the contrary, deep-roasted coffee can be reduced.

Tip 6-what kind of coffee do you like?

The coffee bean itself is also a seed growing in the fruit of a tree, just like a fruit, it will have a sour taste, a cup of fresh and properly roasted coffee, but a rich and balanced sense of sour, sweet, bitter and balanced.

There are two kinds of sour coffee, fresh and properly roasted will show a level of acidity like red wine, with a touch of sweetness. If the coffee beans are not fresh or overextracted, they will have a rotten sour taste or an unpleasant acidity on the tongue.

Tip 7-the best flavor: baking degree and water temperature

When brewing coffee, the hot water temperature varies depending on the extraction tool used and the roasting degree of the coffee, so that you can drink the best flavor of each coffee bean.

For beans with different roasting degrees, the extraction tools are different, and the water temperature should be adjusted between 85 ℃ and 95 ℃ (except cold-extracted coffee). Generally speaking, the water temperature of the deep-roasted coffee is low, and the high water temperature is easy to make the deep-roasted beans astringent and bitter; on the contrary, the water temperature of the shallow-roasted coffee can be slightly higher, and if the water temperature is too low, it will not produce the multi-level sour flavor of the shallow-roasted coffee.

Tip 8-fresh grinding: master grinding thickness

As long as we grasp one principle: "the longer the brewing time is, the thicker the coffee powder is; the shorter the brewing time is, the finer the coffee powder is." in this way, you can avoid that the coffee powder is too coarse and tasteless, and the grinding is too fine. as a result, it comes to a bad end with too much miscellaneous smell and caffeine.

Grinding thickness affects extraction: the finer the particles are, the shorter the extraction time is; the thicker the particles are, the longer the extraction time is.

Finally, I wish you all a good cup of coffee--
