The difference between mechanical and hand-picked coffee beans-Hawaiian hand-picked coffee
I. mechanical picking
Mechanical picking is suitable for coffee plantations with flat land and large areas of cultivation. Afterwards, it is necessary to check the coffee beans picked by the machine and pick out the leaves and branches that fall into the hopper. This method is often used in Brazil.
Advantages: low cost and high efficiency
Disadvantages: Automated machine harvesting will pick up debris such as branches and leaves, and mature and immature fruits will be picked up. This naturally does not have good quality.
II. hand picked
Selective picking, i.e. walking through the trees several times at 8-10 day intervals and picking only the ripe red berries, the higher quality beans are used. There are three types:
1. Twisting method: Harvesting personnel wear a basket at the waist, straighten the branches, and rub them from bottom to top along the branches with mobile phones, so that all the fruits on the whole branches fall into the basket.
2, shaking branch method: Harvesting personnel shake the trunk hard, so that the fruit falls to the ground, and then pick up the basket.
3, artificial harvest method: only pick mature fruits, one by one into the basket.
(Selected coffee is collected manually, divided into 3-6 times)
Advantages: the coffee fruit after picking is uniform in size, close to maturity, and contains no other impurities, which is conducive to later processing.
Disadvantages: high cost
1. Raw bean treatment: washing method, honey treatment, sun treatment method, but no matter which treatment method is used, it is the process of removing pulp and obtaining coffee beans. As for the application of different treatment methods, it is related to the treatment cost and taste demand. You can do it yourself.
2. Roasting: The process from raw beans to ripe beans This process is also the key step for coffee beans to have that aroma. The technical content of this process will be relatively high. If you want to involve it, you need a lot of practice for a long time.
Grinding: The process of turning coffee beans into coffee powder must be preceded by a more uniform and moderate extraction.
4. Extraction: If it is an espresso machine, it is the process of getting Espresso. After adding milk, you can make latte, cappuccino and other kinds of coffee. If it is other appliances, you can get different coffee liquids.
