Defective beans, as the name implies, are defective beans, and poor beans are like bad apples. The causes of the attacks are various and there are many kinds. Let's give a detailed introduction to the things that affect the quality of coffee.

A variety of factors can cause bad behavior. The breeding of defective beans can occur as large as the growth of coffee trees and as small as the process of harvest and treatment of raw beans. But do not despise these lacking beans, if the beans adopted by one or even several coffee bars are full of harmful beans, it will not only affect the coffee civilization of my own brand, but also seriously affect the market merger rate of the entire coffee chain and the reputation of coffee joining the market.

Raw coffee beans will absorb the ingredients contained in the soil of the planting land, and if they contain too much iodine, as in the soil of Rio de Janeiro, Brazil, the final coffee accumulated after adsorption will also have iodine flavor, although it may not be very significant. On the premise of the weather of the coffee growing place, the amount of rainfall will affect the growth of raw coffee beans, and the coffee beans with poor growth will also occur due to lack of nutrients. Worms drill into the coffee fruit to lay eggs and simply form pest beans. Other growth conditions also make up two extraordinary disadvantages: beans and beans. Elephant beans are bigger than ordinary raw beans. Round beans are literally a coffee fruit with only one round seed. When the number of these two kinds is small, it will not have much effect on the taste of coffee, but it is best to pick them out by hand and compare them with each other until the end of the day.

It has poor heat permeability when roasting, and sometimes catches fire, which is an advertisement that causes the astringent taste of coffee. There are other beans, red peas (beans that rain in the process of artificial drying, which taste flat and monotonous), stunted beans (small grains of beans that stop growing because of insufficient nutrients, full-bodied taste), and so on. Occasionally mixed with corn or pepper, and so on.
