How to Make Ice Pour-Over Using the Stirring Method? What Water Temperature, Ratio, and Grind Size Does Japanese Iced Coffee Use?

What Makes High-Quality Green Coffee Beans?

First, look at the bean's surface. Fresh, high-quality green beans have a glossy appearance. Additionally, well-processed green beans have uniform color. Beans with uneven surface coloration cannot be considered good beans, so you must select beans with uniform color when purchasing. Secondly, consistent particle size is evidence of good quality control. When buying, confirm whether the particle size is consistent. Uniform and neat green coffee beans can achieve consistent roasting results; otherwise, some may be over-roasted and bitter, while others may be under-roasted and acidic, both affecting the overall flavor of the roasted coffee beans.

Green beans are classified into several grades based on quality standards, which vary by region. Basically, they are determined by size and shape, with higher grades indicating better quality. Currently, due to the domestic green coffee bean market being in its early stages, the green coffee beans sold are mainly low-grade futures beans. The green beans that consumers receive typically have many defects.

The Dangers of Defective Coffee Beans

Defective coffee beans pose significant risks:

Mutant Beans: Neither flat beans nor round beans, these beans break at the center during dehulling due to developmental abnormalities. These beans tend to roast unevenly.

Fermented Beans/Black Beans: These beans ferment internally during processing or washing. They have fermented sour odors.

Unripe Beans/White Dead Beans: Coffee fruit is harvested before fully ripening. These beans appear ivory-colored after roasting and have a green, astringent taste.

Moldy Beans: These become damp during processing and transportation, exposed to rain, and develop mold growth. Just one moldy bean can quickly spread to others, so extreme caution is necessary.

Insect-Damaged Beans: These are damaged by a pest called the coffee berry borer, have insect holes, and cause coffee to produce off-flavors.

Guatemala is one of the most important coffee-producing countries in Central America. With extensive mountain ranges and diverse regional climates, Guatemala has developed eight major coffee-producing regions, all located in highland terrain under subtropical climates. Abundant and stable rainfall and fertile volcanic ash soil provide an excellent environment for coffee tree growth.

Plan del Guayabo is located near the Volcán de Suchitán volcano. In Spanish, it means "Guava Plain," named after the large number of guava trees cultivated locally. The estate owner is Benjamin Donado. The Donado family has been dedicated to coffee production since 1990, for over 20 years.

Previously, local farmers were quite unfamiliar with coffee production. It was difficult to imagine planting coffee trees in such steep and high-altitude environments. However, it has now been proven that Benjamin made the correct choice back then, specializing in producing high-quality specialty coffee beans with different varieties and processing methods.

In the early days of Guatemala's New East region, berry purchasers would regularly come to buy coffee cherries from farmers, then resell them to larger intermediaries, who would then transport them to Esquipulas town. There, they would be mixed with other batches into a large, untraceable SHB (Strictly Hard Bean) lot, finally sold worldwide under the name "New East."

In response to this situation,越来越多的国际生豆贸易商 are working to change this dynamic. They collaborate with local partners to produce exceptional, traceable green coffee beans, breaking the traditional vicious cycle. Guava Plain Estate is one of the important members in this effort.
