Where do you usually buy coffee beans? the coffee shop buys coffee beans and takes away the guide for newcomers to avoid the pit.

Coffee has become a staple food for many people. There are many people gathered in the offline stores of Qianjie every day, including student parties who stay up late every day to study, daily 996 migrant workers, and retired grandparents. All of these people have one thing in common: they need or like coffee, so they often come to Front Street for coffee.

Looking at the coffee brewing knowledge of Qianjie Coffee Public Number, after a long time, I always want to try to make coffee at home. One of the big questions they face is: where to buy coffee beans? There is a shelf of hand-brewed coffee beans in the offline store on Front Street, but there are not many. When some drinkers who lived far away came to the front street store, the number of coffee beans was often few, and naturally they couldn't choose the coffee beans they liked. Whenever this time, Qianjie will suggest his Taobao shop in Qianjie to buy coffee beans.

Offline, in fact, is the main way most people buy coffee beans now. For beginners, how to choose their favorite coffee is also learned. If you buy coffee beans at Qianjie Online Store, Qianjie will assure you that all products are freshly roasted. The roasting date will be written on the back of the first generation package of Qianjie Coffee. Generally speaking, it will take no more than five days to reach the customer.

How do you know if the coffee you buy is fresh? The front street here summarizes the following tips for everyone:

1. Oil: Light to medium roasted coffee beans, the surface will appear foggy, almost no oil; deep roasted beans, the surface will have small particles of oil, the deeper the roasting degree, the more oil.

2. Aroma: Freshly roasted coffee beans will have a strong aroma; on the other hand, stale coffee looks shiny and smells rich in oil, which means that you have bought stale coffee beans.

3. Foam: Fresh coffee beans still have some undischarged gas, so when hot water is poured on the ground coffee powder, the surface will produce foam phenomenon, coffee beans just like breathing, there will be some bubbles and grease (crema) produced.

In addition, the purchase of coffee beans must not be greedy cheap, it is best to buy from the coffee roasting date can drink a month. Although coffee has a long shelf life, its best taste period is short. Some coffee manufacturers use the central roasting method to produce coffee beans. The shelf life is usually between 12 and 18 months, but the shelf life and freshness are two different things. Coffee beans actually need to look at the taste period. The fresher the coffee beans brew, the better the coffee tastes. Therefore, it is best for people who are pursuing the quality of coffee to drink it within a month. Because the freshness of coffee beans is calculated from the time they are roasted. Freshly roasted coffee beans begin to outgas (mainly carbon dioxide) for about a week, and when the gas is completely exhausted (about two to three weeks), the coffee beans are no longer fresh.

When it comes to exhaust, many coffee brands now use some sealed cans to store coffee, but Qianjie believes that when buying coffee, you should also pay attention to buying products with one-way exhaust valve packaging. Since coffee beans naturally produce carbon dioxide after roasting, direct packaging is easy to cause packaging damage. The purpose of the one-way exhaust valve is to let only air out and not into the bag. Oxygen will oxidize coffee beans, especially high temperature and moisture, which will accelerate the oxidation rate, shorten the best taste period, and long-term exposure to the air will lead to aroma loss, and cause the oil and aroma components in coffee to oxidize and lead to poor quality. The carbon dioxide produced after coffee roasting will make the sealed bag at any time there is a danger of bursting. Therefore, the packaging materials of coffee beans are particularly important.

Many coffee shops in the market have to buy poor quality and cheap green beans because of price competition. Therefore, Qianjie believes that in order to correct such unhealthy trends, consumers should choose coffee beans with "anti-counterfeiting marks" when purchasing coffee beans. For example, there are a lot of Blue Mountain coffee on the market, but the Blue Mountain producing area is not large, and the number of coffee exported is also very limited. So where does the blue mountain coffee flooding China come from? Note that the blue mountain coffee you buy may be fake, those are not blue mountain coffee, they are often "blue mountain flavor coffee" or "comprehensive blue mountain" these coffee beans usually have low content of blue mountain coffee beans, or use quality and oh ah high Colombia coffee-based comprehensive coffee beans, basically imitating the taste of blue mountain coffee.

Blue Mountain Coffee has its own identity card. Blue Mountain Council of Jamaica certification is the identity card of Blue Mountain coffee beans. Front Street Blue Mountain coffee beans come from Clifton Estate in Jamaica, which is the only Rainforest Certified Commissioner in the Blue Mountain Region and is one of the officially certified distributors of Blue Mountain coffee in Jamaica, so Front Street Blue Mountain coffee has an export certificate. When you buy Blue Mountain Coffee online, you must pay attention to whether he has the exclusive barrel of Blue Mountain Coffee and the certification of Jamaica Blue Mountain Council.

Coffee drinking is subjective and everyone has their own favorite flavor. Some prefer the herbaceous aroma of Indonesian coffee beans and the low acidity of wet planing, others prefer the freshness and nature of Ethiopian coffee, and still others prefer the delicate floral aroma of high-altitude Panama coffee. In short, to find "good" coffee, the most important thing is to first understand your preferences. If you are not sure which coffee you like, Qianjie recommends that you drink more. In order to allow many coffee novices and lovers to drink the most classic coffee flavor, Qianjie has produced a series of ration coffee beans. This is a group of cost-effective coffee beans. It may not be as flavorful as some well-known estate beans, but it has the main flavor of each region. A pack of 100 grams costs 25 yuan each. The vast majority of these coffees are washed with water. Why? Because Qianjie believes that the coffee beans treated by washing can best reflect the characteristics of the terroir, the washed coffee tastes the taste of the coffee itself.

Of course, you can also buy other brands of coffee beans on a treasure, combined with the lightning protection method told you before the street, I believe you will be able to find your favorite coffee beans. Finally, the front street still wants to tell you a little trick when buying coffee beans. When buying coffee beans on a treasure, be sure to look at the details of the product. If the coffee can be traced back to its origin and can tell some stories about the origin of the coffee, then the coffee is worth buying when it is not bad.
