Many people are familiar with Kenya AA as the most common标志 of Kenyan coffee in China. In fact, AA is a grade of Kenyan coffee. Below it is AB, and above it are AA+ and AA TOP (premium grade). If coffee beans are only marked as AA, it generally indicates that this coffee is of uniform AA grade, without specific farm or cooperative information, and the flavor may not be the best - it only shows that the bean shape meets standards and has good appearance. However, if the labeling specifies a particular farm, cooperative, or even purchaser, then this coffee, whether AA or AB, is worth trying.

Introduction to PB (Peaberry)

PB stands for Peaberry, which we often call round beans. Typically, one coffee fruit contains two seeds - these are the common coffee beans we see, with one curved side and one flat side, similar to peanut shape, which we call flat beans. Round beans, however, occur when there's only one coffee bean in a coffee fruit. The bean shape is oval, and they account for a very small proportion of the entire coffee tree's fruit. Round beans are all selected manually one by one, ensuring overall quality, so it's not surprising that they taste good.

Pour-over Kenya Brewing Method

15g coffee powder, medium-fine grind (Fuji ghost tooth grinder 3.5 setting), V60 dripper, water temperature 91-93°C. First pour 30g water and let bloom for 27 seconds. Pour to 105g and stop pouring. Wait until the water level in the coffee bed drops to half, then pour again slowly until reaching 225g. Avoid the tail section. Water-to-coffee ratio is 1:15, extraction time 2:00.

Kenya Nyeri Thagrini Peaberry Farm Introduction

Kenya, located in East Africa, is one of the major coffee-producing countries. Approximately 6 million people nationwide are engaged in the coffee industry, mostly in a combination of small farmers and cooperatives. Kenya's coffee trees are mostly grown at altitudes of 1400-2000 meters, with growing regions including Ruiri, Thika, Kirinyaga, Mt. Kenya West, Nyeri, Kiambu, and Muranga. The main areas are the foothills of Mt. Kenya and Aberdare. Many regions in Kenya strive to preserve native forest ecosystems, protect natural gene banks, support the reproduction of wild coffee varieties, and nurture diverse coffee trees.

In the early 20th century, French and British missionaries and researchers selected and cultivated bourbon varieties in Kenya. Over the past century, these have adapted to Kenya's high-phosphorus soil, nurturing the unique acidic fragrance of Kenyan beans, which differs from Central and South American bourbon beans. This Kenyan native variety was created in 1930 by Scott Laboratories, abbreviated as SL. Agronomists wanted to find a bourbon variety resistant to diseases and pests with high yield. Through experiments, they obtained SL28. SL28 is a genetic variant with mixed heritage from French missionaries, Mocha, and Yemeni Typica. The original goal of cultivating SL28 was to mass-produce coffee beans that combined high quality with disease and pest resistance. Although SL28's later yield was not as high as expected, its copper-colored leaves and broad bean shape offer wonderful sweetness, balance, and complex, varied flavors, with significant citrus and dark plum characteristics. This important variety introduces us to the unique Kenyan style: strong, rich fruit acidity, full body, and beautiful balance. Kenya AA is one of these.

SL28 is a delicious variety suitable for growing in medium to high altitude areas with serious leaf rust problems. It can yield 1.8 tons of green beans per hectare. Only when you taste the charming plum-like acidity can you experience Kenya's national treasure.

Region Introduction

This green bean comes from Chakuni Processing Station in Nyeri, produced by surrounding family farms. On 0.5 acres (approximately 2023 square meters) of land, about 250 coffee trees are planted. Nyeri has historically been a classic coffee-producing region in Kenya, relying on Mount Kenya and possessing an excellent environment suitable for coffee growth. Most Kenyan coffee comes from small-scale farmers, about 65%, with large farms accounting for about 35%.

Flavor Profile

Classic Kenyan flavor, rich, high body, caramel, blackcurrant, apple, pure, long aftertaste. Full tropical fruit and fresh citrus aroma, sweet taste as if holding mango, plum and other preserves in your mouth. The refreshing lime aroma that emerges at medium to low temperatures is like drinking iced fruit tea! Very distinctive cherry tomato flavor!! Full of the passionate and bold flavors characteristic of African beans!
