What parameters do you use to manually brew Blue Mountain coffee beans in lightly roasted rose summer? How long should you keep fresh coffee beans? How many days are the best period to enjoy the flavor?

Perhaps many people have had this experience: when they first came into contact with coffee, they received expensive coffee beans from enthusiasts around them. Although they didn't know about them, when they saw many industry terms such as "TOH","BOP","CoE","raw bean competition","first... name","champion" and other industry terms on the information card, they could probably guess that they were worth a lot, so they would always be careful when brewing, but in the end, it was still unsatisfactory.

So when we are faced with a pack of expensive coffee beans, what parameters and techniques should we use to avoid washing it out so as not to waste it?

Why are these coffee beans so expensive?

From Qianjie's perspective, whether high-priced coffee beans are worth it is a matter of opinion. The birth of good coffee, from the landing of a seed to the roasting and brewing, every ring will affect the final result.

Compared with ordinary single products, expensive coffee beans are often dubbed "top". They will first have outstanding flavor performance, which forms a sharp contrast with other varieties. Then there is the scarcity of production, coupled with a series of publicity and marketing, such as competition awards, auctions, origin stories, etc., combine to create its high price.

For the vast majority of consumers, people drink coffee mainly for two purposes. One is to refresh themselves, and the other is taste. At this time, good drinking and not expensive is the king's way, so they rarely spend a lot of money to buy something they are not familiar with."Top coffee." But it is undeniable that some expensive coffees do stand at the top of the quality pyramid, with richer complex aromas and layers. For baristas or players who pursue the flavor ceiling, the ultimate experience brought by this kind of top coffee has irreplaceable value. If you want to not waste them, you must pay attention to the following three details.

1. Don't be too fresh, but keep it fresh.

Qianjie has always placed great emphasis on the freshness of coffee beans, because after the coffee beans are roasted, the aroma will continue to dissipate over time, and there will be basically no flavor in about 50 to 60 days. Therefore, in order to ensure that every guest can Drink the freshest coffee, every package of coffee beans sold on Qianjie is delivered within 5 days after roasting, so after everyone gets it, they have enough time to feel the delicious taste of the beans when they are full of aroma. Assuming that you have been getting coffee beans for some time (more than 30 days), you have to consume them quickly, otherwise no matter how expensive the beans are, they will eventually become bitter water that only tastes like coffee.

Some friends also said that the coffee they brewed was fresh, but after drinking it, their throats would feel dry and choked in their throats, or the taste would be light, which would easily appear green. There was a rough sour and bitter taste, but the aroma was not rich enough. This was because the carbon dioxide gas in the coffee beans was too rich, which hindered the release of coffee flavor substances during brewing.

At this time, Qianjie suggested raising beans first. The roasted coffee beans will be about the fourth day, making the roasting taste of the throat uncomfortable less obvious. Then on the seventh day, the flavor will begin to become full, so in order to improve the flavor performance of too fresh coffee beans, Qianjie is accustomed to resting medium and deep roasted coffee beans for 4 to 6 days and medium and light roasted coffee beans for 7 to 8 days.

2. Understand the basic information of coffee beans

We should be clear that no matter the price, coffee beans can be roughly divided into light ~ medium roasting dominated by sour taste and medium ~ deep roasting dominated by bitter taste. Therefore, Qianjie's brewing plan will always focus on these two directions. In this direction, you only need to determine which category the coffee beans belong to, and then follow the table below to make a selection.

Some people may have noticed that many coffee roasting brands, including Qianjie, do not mark the information of "roasting degree" on their packaging, which makes many novices confused. This is because each store has different understandings and definitions of roasting degree. However, for us ordinary consumers, it is actually very simple to distinguish between the three roasting degrees of light, medium and deep. Just look at the flavor description directly.

For example, the most expensive items sold on Qianjie is Qianjie Jade Estate, red label rose summer, which is light brown to yellow-brown. Its flavors include citrus, compound fruits, peaches and plums, jasmine, and berries. The descriptors are all fruits and flowers., which means that it belongs to the type with medium and light baking;

No. 1 Blue Mountain, Qianjie, known as the coffee emperor, is dark brown to dark when viewed by the naked eye, and its flavor is characteristic of baking such as chocolate, fried nuts, cream, and caramel, so it belongs to a relatively standard medium and deep baking type;

There is also a brown color like Front Street Java, Bolivia. It is characterized by both the sour flavors of flowers and raisins, as well as the milk flavors of nuts and cocoa, which means that it can be divided according to medium, light and medium baking.

3. Improvement in details

Different coffee beans have different personalities. If you want to add flavor to the cake, the parameters must be appropriately fine-tuned according to the original framework as a basic reference.

As mentioned above, many expensive coffee beans have more outstanding flavors, such as Qianjie Jade Rose Summer, Qianjie Rose Summer Village Golden Biao, TOH Guji, etc., which have rich floral and fruity characteristics. In most cases, these beans show more extraction resistance when brewed, so more "extreme" parameters can be adopted to squeeze their essence.

Medium and shallow roasted coffee is represented by the emerald red label of Qianjie Street

When preparing this rose summer, the front street will make adjustments in terms of grinding degree, powder-to-water ratio, and technique. Compared with conventional lightly roasted beans, Qianjie Jade Red Label Rose Summer contains more complex aroma substances, so more water can be used to improve the extraction rate of coffee and create a light flavor, so that the powder-to-water ratio changes from the original 1:15 to 1:16.

As a high-altitude lightly baked beans, the texture of Qianjie emerald red label is hard and can easily sink to the bottom and block the water hole. At this time, the grinding can be appropriately adjusted to the thickness, from the original No. 20 screen pass rate of 80% to 78%, corresponding to the bean grinding machine EK43s scale is 10.3 grids (the C40 bean grinder scale is 27 grids).

Because the heating time of Guixia is relatively short and the water absorption effect is poor, only 25ml of hot water is used to steam Qianjie to ensure that the coffee powder is all moist and exhausted for 30 seconds. After the steaming is over, enter the second stage of water injection and control it to 120ml, and inject it from the middle out to raise the powder layer.

Then wait for the water level to drop. Under normal circumstances, the water level drops at a uniform rate and slowly, and drops to one-third of the powder layer in about 1 minute 10 seconds to 1 minute 15 seconds. You can see that a "bowl shape" has been formed;

At this time, inject the remaining 95ml of hot water around 1/2 of the liquid level. The rest is completed by waiting for the coffee solution to drip into the lower pot and removing the filter cup. The time is about 2 minutes to 2 minutes and 05 seconds.

Zhongshen roasted coffee is used as a demonstration at No. 1 Blue Mountain on Qianjie

Medium and deep roasted coffee takes longer to heat and produces more bitter substances, but for high-grade coffee beans like Qianjie Blue Mountain No. 1, it also means a richer aroma that provides sweetness. In order to make coffee more obvious, Qianjie generally adjusts the water temperature, powder-to-water ratio and technique at the same time.

To create a high sweetness, we still increase the amount of water to improve the extraction of substances, and the powder-to-water ratio becomes 1:16. The powder-to-water ratio takes into account that deep-roasted beans have a charred and bitter taste, and hand-brewed is a slow process. If too extreme parameters are used, the coffee will be over-extracted if you accidentally use it. Therefore, the No. 1 Blue Mountain Street before brewing will use a water temperature that is 2 ° C lower than that of ordinary medium and deep-roasted coffee, that is, 85~86 ° C.

In terms of technique, Qianjie will divide 225ml of hot water into 4 sections and inject it multiple times to increase the layering of the coffee.

First, steam with 30ml of hot water for 30 seconds, and you can see that it will form a round bulge; then inject a second section of 80ml from the center around the outer ring. After injection, the liquid level is about 3/5 of the filter cup;

When the water reaches halfway, continue to inject 70ml of water into the third section, and the circle remains the size of a coin; when the water in the filter cup is almost bottomed out, all the remaining 60ml of hot water can be poured.
