What does hand brewed coffee mean? What is the difference between hand-washed comprehensive blending and single-item beans? How to adjust the front street autumn hand punch match?

Hand-brewed coffee beans are also known as formula coffee beans, mixed coffee beans, blended coffee beans (mainland), English is blend coffee, is a concept relative to single coffee beans, simple distinction is:

Single coffee beans: a packet of coffee beans, all coffee beans produced in the same place.

Hand-brewed coffee beans: a packet of coffee beans, containing more than two different single origin of coffee beans.

A simple example:

1. Ethiopian Yirgacheffe Worka: This name refers to the coffee beans produced by Woka (cooperative) in Yegacheffe (large area) in Ethiopia (country). Each coffee bean comes from Woka. This is obviously a single bean. Once cooked, you can experience the characteristics of Yegacheffe Worka.

2. Red Velvet: This kind of name, which has neither country nor production area, is usually a comprehensive bean. In fact, there are no rules for the name of the store. Most of them like to choose a name that sounds wonderful according to the tonality and taste of the coffee. Some simply use the experimental number of works. Of course, there are also inexplicable ones. This is still a hobby of the store. Fortunately, most stores will specify that this is a hand-brewed coffee blend, and some will indicate which individual coffee combinations are made.

Generally, it is still called comprehensive beans. After all, when this formula was developed, it was still treated as three independent works with different flavors, and the three beans were mixed and baked in different proportions to stack different flavors. Therefore, it is more appropriate to call it comprehensive beans.

The purpose of preparing hand-brewed coffee beans:

Hand-brewed blended coffee beans are usually prepared for four purposes

1. Hand brewed coffee beans Coffee formula

At present, in fine coffee, hand-brewed coffee beans are still the mainstream, while Italian coffee is bound to add dairy products, while sour coffee or coffee with too thin taste is not suitable for adding to milk.

From the above two cases, it can be seen that there are many changes in Italian beans, and to be able to bake the ideal taste is a test of the coffee shop's understanding and combination of flavor, so judging the quality of Italian beans is one of the criteria for many people to judge a coffee shop. However, personal advice does not have to be so critical, as more fun, more appreciation, more imagination of other people's home righteousness beans, to help themselves more.

2. Suitable for long-term supply:

This is still relevant to Italian coffee, which is generally served in coffee shops with strict proportions of ingredients to maintain the quality of the cup. The coffee beans with the greatest impact happen to be the most problematic materials, especially when using a single item to make espresso coffee, often facing the problem of a single item out of stock, and if you want to change to another kind of single item beans, there will be a big trouble that the formula must be readjusted.

3. Simulate special flavors:

This goal is generally less common in boutique cafes, most of which are commercial coffees that use blended beans for flavor modification in order to mimic certain brand name coffees.

The most common examples are so-called "Blue Mountain" coffee,"Civet" coffee, and "Old Pit" coffee, which are products with flavor names that often don't have a single Blue Mountain in the entire bag of coffee beans, just a patchwork of other coffees: the imaginary Blue Mountain flavor. Of course, it may also be mixed with a little coffee beans of origin, such as the ancient pit coffee sold on the market. The whole bag of beans often does not exceed 10% of the ancient pit, and a large number of beans from other origins are used to make up the number.

4. Taste Challenge Composition:

If a boutique coffee shop has the ability to prepare hand-brewed mixed coffee beans, sometimes it will prepare several mixed beans with different flavors, which will make the drinks of the store more varied.

From the moisture content point of view, the same washed 2 beans are relatively close, and the bean quality is soft, but the relatively large particles of Yunnan and the harder but smaller particles of Kocher are also close in heat conduction, mixed baking of these 2 beans is not easy to cause uneven baking; and we use the step-by-step reduction of the fire baking method, after dehydration and homogenization, there is a longer Mena reaction time so that the 2 beans tend to develop more synchronously.

In the determination of roasting degree, we also adopted "take the middle value". Such development time and lower bean temperature not only effectively removed the sour taste and excessive herbal flavor of Yunnan coffee, but also well retained the flower and fruit fragrance of Yejia.

300 grams of beans, beans temperature 170 degrees, turn off the fire beans. Fire 140, throttle 3 in 30 seconds. Bean temp 140, fire down to 120, throttle 4. Dehydration turns yellow in 4 minutes and 30 seconds. Reduce fire to 90 again at 168 degrees. The first explosion starts about 8 minutes, the damper is opened to 5, and the first explosion develops for 1 minute and 45 seconds to 195 degrees.

In terms of proportion, we chose Huaguoshan for the first time: Kocher-6:4 ratio, cup test results: cleanliness is good, sweet, apple fragrance, plum acid, orange aftertaste. The overall impression is that the taste is good, but the flavor is slightly thin.

[Bean Mix Adjustment]

Therefore, after a cup test discussion, we decided to add a flavor enhancement bean-[Rose Summer Village Rose Summer] sun, this time using the ratio of Huaguoshan: Kocher: Rose Summer-6: 3:1.

Reducing the proportion of Kocher makes the acidity of the whole bean softer than before, and 10% of Guixia Village brings more fruity flavor, but also enhances the floral and later tea aroma.

In order to retain more flower and fruit aroma, the baking temperature will be reduced a little; the time from dehydration to first explosion will be shortened slightly, and more reactive substances will be retained and the development time of first explosion will be increased.
