Quick answer
Use a 1:16 coffee-to-water ratio, a medium-fine grind, and water just off the boil (around 200-205°F). Start with a 45-second bloom, then pour in slow spirals to finish the brew in 2:45–3:15. This method brings out the bright, fruity notes of the light anaerobic natural roast without letting bitterness creep in.
Why this coffee rewards a careful pour-over
Rwanda Nyungwe is a light roast anaerobic natural from the Nyungwe forest region, grown at 1800 masl. Its Red Bourbon lot delivers the tradition and complexity that make Rwandan coffees stand out. Because it's a light roast, it has less soluble material than darker roasts, so you need to extract a bit more to get the full flavor. A pour-over gives you control over every variable, which is exactly what this coffee needs.
Red Bourbon
If you normally brew dark roasts, you'll want to adjust your routine: use slightly hotter water, a finer grind, and a slower pour. The goal is to pull out the fruit and acidity without over-extracting and creating a dry, bitter cup.
Gear and prep that make a difference
A cone dripper with a paper filter works well for clarity, but a flat-bottom dripper can also work if you adjust the grind slightly coarser. Rinse the filter with hot water before brewing to remove paper taste and preheat your server. Weigh your beans and water—a scale is non-negotiable for consistency. Grind just before brewing; pre-ground coffee loses aromatic compounds quickly.
Use filtered water. If your tap water tastes like chlorine or has a lot of minerals, it will flatten the coffee's bright notes. A simple carbon filter or bottled water with moderate mineral content is fine.
Step-by-step brew recipe
This recipe makes one 10-ounce (300 ml) cup. Adjust quantities proportionally for larger batches. The key is to keep the water temperature steady and pour gently.
Brew steps with checkpoints
- 1. Heat water to 200–205°F (93–96°C): Water temperature is critical for light roasts. If it's too cool, the coffee will taste sour and underdeveloped; too hot, and you risk scorching the delicate fruit notes. Use a variable-temperature kettle if you have one. Checkpoint: If you don't have a thermometer, bring water to a boil and let it sit for 30–45 seconds before pouring.
- 2. Weigh and grind 18g of coffee to medium-fine: You want a texture like table salt—slightly finer than you'd use for a dark roast. If your grinder produces a lot of fines, sift them out to avoid clogging the filter. Common mistake: Grinding too coarse leads to a weak, sour cup. Adjust finer if your brew drains in under 2:30.
- 3. Place filter in dripper and rinse with hot water: This removes papery taste and preheats the brewer. Discard the rinse water. Add the ground coffee and gently shake the dripper to level the bed. Checkpoint: The dripper should feel hot to the touch before you add coffee.
- 4. Bloom with 50g of water for 45 seconds: Pour just enough water to saturate the grounds, starting from the center and spiraling outward. You'll see bubbles as CO2 escapes. This is normal for fresh coffee. Wait 45 seconds. Common mistake: Skipping the bloom or rushing it. A proper bloom ensures even extraction and prevents channeling.
- 5. Pour in stages to 300g total: After the bloom, pour slowly in a spiral from the center outward, keeping the water level steady. Aim to finish pouring by 2:30. Give the dripper a gentle swirl to flatten the bed. Checkpoint: Total brew time should be 2:45–3:15. If it's faster, grind finer; if slower, grind coarser.
- 6. Serve and taste: Let the coffee cool for a minute or two. The flavor will open up as it cools. Look for bright fruit notes and a clean finish. If the cup tastes sour, try a finer grind or hotter water next time. If bitter, grind coarser or lower the temperature slightly.
About the coffee in this guide
- Rwanda Nyungwe - Process Coffee: Rwanda Nyungwe is a light roast anaerobic natural from the Nyungwe forest region of Rwanda, roasted by Belfast-based specialty roaster Process Coffee exclusively for Fellow Drops. The anaerobic natural process and light roast mean you'll get fruit-forward flavors and higher acidity, so brewing with slightly hotter water and a finer grind helps balance the cup.
