African Premium Pour-Over Specialty Coffee Bean Grading Guide

If you drink pour-over coffee regularly, African beans need no introduction. Top-quality coffee from Africa's growing regions is famous for its bright acidity and abundant floral aromatics. But the beans we buy often carry all sorts of grade labels — Ethiopian G1, Kenyan AA, and so on. How are these grades actually assigned? There's no single unified system: every producing country grades in its own way. Take Africa's two most famous origins, Ethiopia and Kenya — their grading approaches could hardly be more different.

Kenyan Coffee Bean Classification

Kenya grades its coffee by bean size. The largest beans are classified as Grade E — the so-called "elephant beans" — abnormally developed beans that measure over 18 screen size. Next comes AA, the grade most commonly seen and consumed, covering beans between 17 and 18 screen size. From there, the grades continue down to progressively smaller beans.

Ethiopian Coffee Bean Classification

Ethiopia grades by defect count instead. The standard works like this: fewer than 3 defective beans per 300 grams qualifies for the top grade, G1; 4 to 12 defective beans per 300 grams earns G2; and so on down the scale. Unsurprisingly, the specialty coffee most of us drink is almost always of the highest G1 grade.

FrontStreet Coffee Recommendation

There's no better place to put that G1 label to the test than Ethiopia itself — the birthplace of coffee, home to countless heirloom varieties and a favorite origin among pour-over lovers. For a first taste, FrontStreet Coffee's washed Yirgacheffe is the classic entry point: crisp jasmine florals and bright citrus acidity in a light, elegant, tea-like body, like a clean lemon tea. Yirgacheffe is a small town in southern Ethiopia whose cool, misty, spring-like climate has nurtured thousands of coffee trees and a signature interplay of florals and fruit.

If you'd like to go a step further, try the FrontStreet Idido Cooperative lot from the Worka area — a washing station that became an independent cooperative of roughly 300 farming families in 2012. Because the fruit is pulped before drying, the washed beans show remarkably clear flavors of citrus, lemon, and elegant white florals. And for a natural-process contrast, the FrontStreet natural Hua Kui from Hambella, Guji, is dried for 21 days on raised beds and turned constantly to prevent mold, yielding a fuller, more complex cup of fermented wine notes, florals, citrus, and mango with a thick body and long finish.
