Kenya PB? Flavor and taste characteristics of coffee round beans 8 grades and standards of Kenyan coffee

Peaberry means that one coffee bean grows in a cherry, not two. Because the rounder shape minimizes the sharp edges, it makes it easier for the berries to roll in the baking room and roast slightly more evenly, bringing a very consistent flavor to the coffee.

Kenyan round bean coffee tastes similar to Kenyan AA coffee.

Kenya round beans (PB) coffee beans are a natural mutation in the reproductive cycle of coffee trees, when coffee fruits produce only one kind of coffee beans instead of two. Peaberry beans must be manually sorted after picking to separate the rounder, fatter beans from their double counterparts. This increases the price of Peaberry, some people say, because there is only one kind of bean, it will get more flavor, taste and sweetness when baking.

In the dry mill, the coffee will pass through the stripping machine, the thresher and the polishing machine before reaching the sorting machine where the letters appear.

A sorting machine is a giant sieve that sorts grains according to size. In this case, the rank is a physical parameter, not one of the masses.

AA: Screen 18, (15-20% of total output)

Kenya's AA coffee beans grow at an altitude of more than 6600 feet. Kenya AA is considered to be one of the best specialty coffee in the world.

Some Kenyan AA coffee is light and still very bright and shows a floral aroma. Passion fruit and wine flavors are often present, which is almost always balanced by fresh acidity, which is one of the reasons why it is one of the best gourmet coffee in the world.

AB: screen 16.

Kenya AB coffee beans are made up of coffee beans An and B. Class A uses 6.8 mm screening, while Class B uses 6.2 mm screening. These two legumes, An and B, are mixed together to form a Kenyan AB. Although it does not have the high value of Kenyan AA, Kenyan AB is also very popular and is rated as high-quality coffee. In general, the Kenyan AB grade is the most abundant in certain goods and is used as a representative of other grades.

C: screen 15Universe 10.

PB: Kenya PB coffee beans are pea coffee beans. There is only one coffee bean in a cherry instead of the usual two and a half beans. About 10% of Kenyan coffee beans are round beans E: elephant beans super soybeans

TT Kenya TT coffee beans are the result of the separation of light coffee beans from Kenya E, Kenya AB and Kenya AA coffee beans by suction.

T Kenya T coffee beans are made up of broken, defective, thin and small coffee beans or lightweight coffee beans separated from Kenyan grade C coffee beans.

MH ML Kenya MH/ML coffee beans account for about 7 per cent of Kenya's coffee production. These coffee beans either follow from the falling coffee plant itself to maturity, or are not picked at all. MH/ML coffee beans usually have a distinct sour taste.

All coffee delivered to the dry mill will go through the same process and will be classified throughout the season.

We can find some interesting things:

The price range of AA grade is very large, and the quality varies greatly.

If you look at the worst price in Class C, it is higher than the lowest AB price of the day. The best price for PB is higher than the best AB price of the day.

At the same time, we cannot say that the denser and heavier coffee beans will not taste better than the lighter C-grade coffee beans in the same batch. But it is important to know that this is not always the case or the rules.

The conclusion is that AA batches may taste as bitter or fermented as C or T due to processing problems. Although many PB and AB taste better than bad AA, they are also more expensive.

At present, there is only Kenyan AA AB coffee in Qianjie. It is recommended that you first standardize and compare the flavor of the two with the following brewing methods.

Recommended cooking method: hand flushing

Filter cup: v60 filter cup

Water temperature: 90-92 °C

Amount of powder: 15g

Powder / water ratio: 1:15

Degree of grinding: medium and fine grinding (Chinese standard No. 20 screen pass rate 80%) flushing and cooking method: segmented extraction

Steam with 30 grams of water for about 30 seconds, when 125 grams of water is injected around the center of the small flow, continue to inject water to the end of 225 grams when the water level is about to expose the powder bed, and remove the filter cup when the water level is about to expose the powder bed. The extraction time is 2 minutes 39 percent 00 ".
