What is the difference between PWN Gold Manning and G1 Manning introduction to the grading system of Mantenin coffee beans

I believe that friends who like full-bodied coffee should be no stranger to Indonesia's golden Manning. PWN acquired the G1 grade Mantening coffee raw beans and carefully selected to ensure high quality, neat granules, clean and bright. The Mantenin coffee on the front street bean list is the gold manning from PWN, which shows rich dark chocolate, caramel, nuts and unique herbal and spicy aromas.

How to grade raw coffee beans in Indonesia?

Indonesian coffee is graded mainly according to the number of defective beans, supplemented by size. Indonesia's general quality requirements are no live insects, no mildew and rotten beans, with a maximum moisture content of 12.5%. The impurity rate is less than 0.5%. According to the defect rate classification (based on 300g), the grade Grade standard is mainly divided into six levels, namely G1-G6.

Grade

Grade

Standard

G1

Grade 1

The total defect is less than 11

G2

Grade 2

Total defects are greater than 12 and less than 25

G3

Grade 3

Total defects greater than 26 and less than 44

G4a

Grade 4a

The total defect is more than 45 and less than 60

G4b

Grade 4b

Total defects are greater than 61 and less than 80

G5

Grade 5

Total defects greater than 81 and less than 150

G6

Grade 6

Total defects greater than 151 and less than 225

Usually the rough sacks of Indonesian coffee with raw beans will be marked: national + graded + raw bean merchants, such as Lindong Manning coffee and PWN gold Manning coffee on the Qianjie bean list are all G1 grade.

Characteristics of PWN Gold Manning Coffee

"Golden manning" is the exclusive brand of PWN Coffee Company in Indonesia. There are many different types of mantenin products on the market. As the PWN company registers the English "Golden Mandheling" of the golden manning as the company's trademark, only the golden manning coffee produced by the PWN company is the gold manning in the real sense. You can identify the authentic gold mantenin according to the raw bean sack with the PWN logo and a certificate of origin signed by PWN, which are displayed in the Dongshankou store in Qianjie.

At that time, the Japanese took a fancy to Sumatran coffee after buying it for a long time, and gradually found that the quality of local beans was often mixed. So he paid more attention to the production of Mantenin and began to formulate strict standards and methods for screening defects, including the density, specification, shape, chromaticity and other values of beans, and the resulting Mantenin needed to be removed by machine and manner. to ensure that the resulting Mantenin particles are complete, uniform, large and bright, but also reduce the soil and fishy smell of Mantenin. It is rumored that it is golden in the sun, so it is named "Golden Manning".

The classification of raw coffee beans in Indonesia is based on the number of defective beans, supplemented by specifications. General quality requirements are no live insects, no mildew and rotten beans, with a maximum moisture content of 12.5%. The impurity rate is less than 0.5%. According to the defect rate will be divided into six grades, of which the highest grade G1, the total number of defective beans in 300g samples must be less than 11. The Lindong Manning coffee in the Qianjie food bean series is G1, which is treated with wet planing, which is the conventional version of Indonesian Mantenin flavor.

PWN, which is the best in screening, buys Mantenin raw beans with more than 18 mesh, and the G1 grade with less than 3 defective beans in 300g samples, that is, the highest grade of Indonesian raw beans. In the follow-up, 1 machine selection + 3 manual selection of defective beans will be carried out in strict accordance with the standard to ensure that the shape and size of Mantenin coffee beans are uniform. In addition, PWN will also put the raw beans in the machine for density color separation before packaging, so as to make the golden manning color even and bright. As a result, PWN gold manning will taste cleaner and brighter, and the mellow thickness and sweetness will be more obvious.

The suggestion of cooking in Qianjie

Like Golden Manning Coffee, which has a strong taste and strong regional flavor, Qianjie suggests using hand-made black coffee to extract and taste it to better taste the aroma of the coffee. The coffee beans shipped in Qianjie are freshly roasted within 5 days, so that when we receive them, they are still the freshest stage, which can add more flavor levels to our cups.

Due to the medium-depth roasting of golden Mantenin coffee beans, the internal texture of coffee beans is loose and has strong water absorptivity. if you use the water temperature and grinding degree of shallow roasted coffee beans, the coffee is easy to extract, showing an unpleasant scorched taste and astringent feeling. In order to avoid this, Qianjie baristas will lower the water temperature and thicken the grinding degree to reduce the release of bitter macromolecules in coffee. The front street will use hot water of 87 degrees Celsius and a medium grinding degree (70% of the pass rate of the Chinese standard No. 20 sieve), together with a KONO filter cup for extraction.

Three-stage water injection: first inject 30 grams of water for steaming for 30 seconds, inject fine water from the central point and slowly circle to 125 grams, wait for the water level in the filter cup to drop to 225 grams around the powder bed, and the total extraction time is about 2 minutes.

The entrance of hand-made gold Manning coffee can feel a strong aroma of dark chocolate, with very mixed flavors of baked hazelnut, caramel and melon, with obvious spice aromas in the mouth and a long finish.
