Rwanda - Kilimbi - Anaerobic Natural

A fruit forward coffee with notes of juicy, ripe plum, grape candy, grenadine and fruity dark chocolate complemented by a balanced acidity, a date-like sweetness and syrupy body.

Producer: Small-holder producers - Kilimbi Washing Station

Region: Nyamasheke, Western Province, Rwanda

Varietal(s): Red Bourbon

Process: Anaerobic Natural

Altitude: 1,800 masl

Recommended rest time: at least 10-14 days post roast (if you want to get into it early, it tastes nice right out of the roaster but gets considerably better with rest)

Founded in 2016, Kilimbi may be one of Rwanda’s smaller washing stations, but its impact has been outsized from the beginning. Located along the shores of Lake Kivu, the station quickly gained recognition after earning distinction in Rwanda’s Cup of Excellence, helping establish Kilimbi as one of the country’s most progressive coffee producers.

Under the leadership of agronomist Joseph Ntarindwa, Kilimbi became the first washing station in Rwanda authorized to export natural and honey processed coffees. At the time, these processing methods were still largely unexplored within the country’s specialty coffee sector. Kilimbi’s success helped open the door for wider experimentation across Rwanda, paving the way for producers seeking new approaches to processing and flavor development.

Beyond processing innovation, the station maintains a strong focus on long-term quality and producer support. Joseph works closely with surrounding producers throughout the growing cycle, providing agronomic guidance before and after harvest to help improve cultivation practices, coffee quality, and consistency year after year.

This lot underwent an anaerobic natural process, where coffee is fermented in oxygen-limited environments before drying with the fruit intact. The result is a vivid, fruit-forward cup that highlights both the expressive potential of the process and the quality of the coffee itself. Joseph works closely with surrounding producers throughout the harvest cycle, providing agronomic support aimed at improving quality and consistency year after year.

Anaerobic natural coffees are often celebrated for their intensely fruit-forward character, but they can sometimes lean so heavily into fermentation-driven flavors that balance and clarity are lost. This lot from Kilimbi offers a different expression. While it delivers the vibrant fruit notes and sweetness that make anaerobic naturals so compelling, it does so with remarkable restraint and structure. The fermentation enhances the coffee rather than dominating it, allowing the underlying character of the coffee to remain clearly intact. The result is a cup that is expressive and complex yet refined, showcasing both the possibilities of the process and the quality of the coffee itself.

Brew Guide

Hario V60 Dripper 

This coffee works great with a pretty standard by-pass style pour over recipe. This recipe highlights the fruit character and syrupy mouthfeel of the coffee.

Recipe

Coffee: 25 grams

Grind size: 5.5 on the Fellow Ode (medium)

Water: 375 grams at 200˚F

Coffee to Water Ratio: 1:15

Method

1.     Rinse filter

2.     Add ground coffee

3.     Start timer and saturate grounds with 75g of water.

4.     Let bloom one minute.

5.     Slowly pour another 225g of water on the coffee, taking care to evenly saturate the grounds. You should end up with 330g of water poured by about 1:45.

6. Swirl brewer to ensure an even draw down of water through the bed of coffee.

7. After all water draws down, remove the brewer from your carafe. 

8. Add 45 grams fresh, hot water to the carafe to dilute the brew to the proper strength.

9. Swirl the carafe once more to ensure the brew is homogenized.

Espresso

Gotta love a syrupy, fruit-forward shot!

Recipe

Coffee in: 18 grams

Coffee out: 36 grams

Brew ratio: 1:2

Extraction time: 30-35 seconds

Extraction tips

If your shot is too intense, try a wider ratio. If it is too weak, try a tighter ratio. Depending on machine and grinder used, these complex, fruity coffees can benefit from wider ratios and longer extraction times. We found great results with a pretty standard ratio but results may vary.
