If you’re a coffee lover or you run a roasting business, you know that sourcing the right beans is crucial to making the best cup of coffee. Whether it’s dark, light or decaf beans, there are many factors to consider when picking green coffee.

Selecting high quality, fresh and sustainable green beans isn’t an easy task. But it’s well worth it.

Origin

When you want to brew the perfect cup of coffee, it’s important to pick กาแฟ ยี่ห้อ ไหน ดี for the job. The origin of the green beans can have an impact on how the brewed coffee tastes, so it’s crucial to know how the green beans were harvested and processed.

Ethiopia, regarded as the birthplace of coffee and the origin of the Arabica bean, produces the finest quality green beans for roasting. They can be dry (natural) or fully washed and can yield “fruit bomb” flavors, or delicately sweet and floral notes.

Colombian green coffee beans are also a เมล็ด กาแฟ สด ที่ นิยม. They are mellow-flavored and make a great base for blends. These beans are hand-picked and sorted by farmers before being transported to the roastery, and they are then roasted in small batches.

Processing

One of the most important aspects of coffee quality is the processing of green beans. Choosing the right process can make all the difference between delicious flavor and a bitter cup.

There are two major processing methods – dry and wet – both of which may include a number of different cleaning and grading processes to achieve a final product that is marketable.

Dry processing involves removing the fruit flesh from the green bean, usually with a depulper, before laying them out to dry. Traditionally, this method was mainly used in developing countries, but is now being embraced more and more by specialty roasters.

The process of removing the fruit flesh can also result in some coffee beans having a sour or unpleasant taste. Typically this is because of fermentation after the fruit flesh has been removed.

Storage

As you can imagine, a fresh coffee bean will have a different taste and aroma from a roasted one. This is because roasted beans go through a roasting process that changes their chemical composition.

While a good roasted coffee has its charms, the flavor of unroasted green coffee beans can be just as delicious if you know how to pick them. You can do this by checking the color, smell and touch of the beans.

You can also perform coffee cupping, a method of tasting the beans for their unique taste and aroma. This will help you pick the best-unroasted green coffee beans for your preferences.

Like all fresh plant products, the quality and flavor of unroasted green beans are affected by light, heat, air, moisture, time and pests. Therefore, they should be stored in a stable and cool environment.

Roasting

Getting the best flavor and quality from coffee beans requires skilful roasting. However, a poorly-roasted bean can result in bitter, woody or papery flavors.

Green beans can be roasted as dark or light as you like to brew your coffee, but remember that the darker they are roasted, the less acidity and sweetness they will have. This makes it important to buy a good range of different green beans, so you can pick the right one for each brew.

You can also check out your local roasting shop for advice on the types of green beans that will be suited to your needs. Alternatively, you can order your beans online from a supplier.

You can store your green coffee beans for up to twelve months without losing their quality if you keep them in a cool, dark, and pest-free environment. The best way to do this is to use vacuum-sealed bags, as they keep out moisture and odours that can affect the flavor and aroma of the beans.
