Brew Rwanda Tumba as a pour over to highlight its Earl Grey, lemon, and honey notes. Get a grind size, ratio, and step-by-step recipe that keeps the tealike body intact.
Quick answer
Brew Rwanda Tumba as a pour over with a medium-fine grind, a 1:16 coffee-to-water ratio, and a total brew time around 2:45. This keeps its Earl Grey tea, sweet lemon, and honey notes clear without flattening the tealike body.
Why a pour over suits this washed Rwandan coffee
Tumba comes from Rwanda's Rulindo district and is a washed coffee, so the cup is clean and the acidity is bright rather than heavy. A pour over lets you control water temperature and pour speed, which matters when you want the lemon acidity to stay lively and the honey sweetness to round it out.
If you usually drink darker, nuttier coffees, expect a lighter body and a tea-like finish. That is the point of this coffee, not a sign that you brewed it wrong.
Grind size and ratio: where most brews go off track
Start with a medium-fine grind that feels like fine sand, not powder. Too fine and the brew stalls, pulling out bitterness that hides the lemon; too coarse and the cup tastes thin and watery, losing the honey roundness.
Use 15 g of coffee to 240 g of water. If your grinder has numbered settings, treat the first attempt as a baseline and adjust one notch finer if the cup tastes weak, one notch coarser if it tastes harsh or dry.
When to change the recipe
If the cup tastes sharp and the lemon dominates, shorten the brew slightly or grind a touch coarser. If the tea note disappears and the finish feels empty, grind finer or raise the water temperature by a few degrees.
For a stronger cup, increase coffee to 17 g rather than grinding finer; that preserves the clarity that makes this washed Rwandan coffee worth brewing carefully.
Step-by-step Rwanda Tumba pour over recipe
- Heat water and rinse the filter: Bring water to 200–205°F (93–96°C). Rinse the paper filter with hot water, then discard the rinse water. Common mistake: skipping the rinse leaves a papery taste that masks the Earl Grey note. Check that your kettle holds temperature steady before you start pouring.
- Weigh and grind: Weigh 15 g of Rwanda Tumba and grind medium-fine. Common mistake: grinding too fine for a pour over, which slows the drawdown and turns the lemon acidity bitter. If the grinder setting is unfamiliar, grind a small test batch and compare texture to fine sand.
- Bloom the coffee: Place the dripper on your scale, add the grounds, and pour 45 g of water. Wait 30–40 seconds. Common mistake: pouring the full bloom volume too fast and letting the bed go dry before the next pour. A bloom that bubbles evenly is a good sign the coffee is fresh.
- Pour in stages: Pour in slow spirals to 120 g, pause briefly, then continue to 240 g. Keep the water level below the dripper rim. Common mistake: pouring down the filter wall, which bypasses the coffee bed. Aim for a total brew time near 2:45; adjust grind if you finish far outside that.
- Swirl and serve: Give the dripper a gentle swirl after the final pour to level the bed, then let it drain fully. Serve immediately. Common mistake: letting the brewed coffee sit on a hot plate, which dulls the honey sweetness. Taste the cup at a few temperatures; the lemon note often becomes clearer as it cools slightly.
About this coffee
- Rwanda Tumba: Washed Rwandan coffee from the Tumba washing station in Rulindo, with tasting notes of Earl Grey tea, sweet lemon, honey, and a tealike body. Those notes tell you to brew for clarity and sweetness rather than heavy extraction, so a medium-fine pour over is a better starting point than a fine espresso grind.
