Tasting Notes

A striking coffee with rich fruit flavors and a mature, sweet sensation, showing blackberry and rosehip with subtle black tea and floral notes.

Grade

AA (soil: red volcanic ash)

This is the highest grade of Kenyan coffee that Nairobi exporters buy at the Kenya coffee auction. Among Kenyan producing regions, Kirinyaga and Nyeri in particular are famous for high-quality coffee, and they draw close attention from specialty coffee professionals in Europe and America. The aromatic, varied fruit flavors leave a lasting impression. Other varieties purchased this time are also highly rated specialty coffees, all Kenyan coffees with an excellent aromatic aftertaste.

Kenya Kainamui Gichugu is a coffee our editor considers a must-have for home brewing. The flavor is gentle, with ample fruit and sweet aromas, and the key point is that it tastes excellent no matter how you brew it. We have tried pour-over, cold brew, and espresso, and none of them disappoints.

Coffee Grind Size and Brewing Guide

Coffee grind size is generally divided into five levels: coarse, medium, medium-fine, fine, and very fine.

Light roast coffee uses a medium-fine grind, which suits lighter roasted beans. Today we are using a Hario V60 transparent resin dripper, with a Fuji Royal grinder setting of #3.5 - granulated sugar size, the most common granulated sugar sold in supermarkets, slightly larger than regular sugar - and demonstrating with [Kenya Asali] for brewing instruction.

FrontStreet Coffee's brewing recommendations for Kenya AA beans: medium-light roast Kenya AA is suited to extraction at around 90-92 degrees Celsius, while dark roast Kenya AA is suited to 86-88 degrees Celsius.

First Pour

Pour from the center with a small stream, then spiral outward slowly, as if gently laying a layer of water on the surface of the powder. Even with a small stream, be careful not to slow the circular motion deliberately: if the circle is too slow, the water will run in a single direction and the bed will absorb it unevenly.

Once the first pour ends, the coffee particles push against one another as they degas, and the bed expands. When that expansion peaks or nearly stops, and the surface water gradually dries, it is time for the second pour.

Second Pour

The second pour also starts from the center, driving into the bottom of the bed with a small stream. To concentrate the stream's penetrating power, keep the circular motion small - about the size of a coin - then spiral outward. From the start of the second pour, watch the water volume and try not to exceed the height of the bed. That means stopping when the stream approaches the filter paper.

During the initial pour, most particles are actively degassing, and the resulting airflow quickly reaches the edge of the filter paper. If you pour too much water at once, it will carry water to the sides instead of the bottom layer, so keep the stream small and the circular motion faster to avoid that problem.

As the thicker layer of powder at the original filter paper edge grows heavier from absorbed water, it slides down and thins as the water level drops. When the level reaches halfway, you can move to the third pour.

Third Pour

From the third pour on, watch the rate at which the water level falls. Again, start from the center and spiral outward, keeping the water volume below the height of the bed. At this point the foam has filled the surface. The third pour should increase the rolling of the coffee particles, letting the settled grounds roll so their soluble material dissolves.

The rolling particles begin to settle once pouring stops. At that point, rely on the flow rate created by the falling water level to generate friction between the particles. Once pouring stops, the particles sink and can block the filter, so pay close attention to the pouring rhythm.

If there are too many pauses in the pour, it is effectively letting the particles soak continuously, which leads to astringent and impure flavors in the later stages of extraction.

As you approach the target - 15g coffee, 225g water - you can remove the dripper.

FrontStreet Coffee Recommendation

If this Kenyan AA has shown you how juicy and structured a good washed East African coffee can be, FrontStreet Kenya Little Tomato takes that style in a fruitier direction. It comes from Kenya's Sika region, grown at 1,550-1,750 meters from the classic SL28 and SL34 varieties, and it reaches the AA TOP grade. It is processed with Kenya's distinctive 72-hour double washed fermentation, which draws out the fruit while keeping the cup clean and pure, and FrontStreet roasts it light to preserve the lively acidity and layered fruit. Expect cherry tomato and dark plum up front, pear and black plum in the middle, and a clean, long finish with yellow sugar sweetness and a touch of green tea.

Because the acidity of a Kenyan coffee like this is so refreshing, it also makes an outstanding cold brew. FrontStreet Yirgacheffe Gedingding Cooperative is another excellent candidate for cold extraction: as a washed Yirgacheffe, it brings the clean, bright sweet-and-sour character and the wallet-friendly daily-drinking positioning that make it a go-to single origin for home users, and it works across pour-over, siphon, French press, and cold brew. Cold brewed, it shows sweet berry, layered structure, and honey.

For something more intensely aromatic, FrontStreet Colombia Sidra is worth trying cold as well. Grown at 1,650-1,800 meters on a champion-caliber variety and processed with a double anaerobic natural method, it is roasted medium-light to keep the native fruit aromas intact: jasmine and citrus on the dry aroma, then passionfruit, blueberry, grape, and apricot in a bright, gentle juice-like cup with a long cocoa finish. In an iced pour-over, its clean, smooth grape-juice character stands out especially well.
