  • Dose (Coffee): 18.5g
  • Yield (Water/Output): 300g (Ratio 1:16.2)
  • Grind Size: fellow ode gen2: 5.2 - 6.0 | comandante c40: 21 - 23 clicks | mahlkonig x54: 23 - 25 | mahlkonig ek43: 9.5 - 10.0 | eureka mignon specialita: 4.8 - 5.2 turns | timemore c3: 15 - 16 clicks
  • Water Temperature: 93°C
  • Brew Time: 3:00 - 3:30 minutes
  • Equipment Note: Matched: wave-185-stainless, stagg-ekg-pro

Step-by-step Instructions:

1. Insert Wave 185 filter. Rinse gently in center without flattening horizontal corrugated waves.

2. Add 18.5g ground coffee.

3. Bloom with 55g water for 45 seconds.

4. Pulse pour in 50g increments: 105g, 155g, 205g, 255g, and finish at 300g.

5. Flat 3-hole bottom maintains even saturation, maximizing caramel sweetness.

Rwenzori Dial-in Pro-Tip: The horizontal wave flutes insulate brew water from metal walls, maintaining constant 91°C slurry temperature.

V60 Pour-Over

  • Dose (Coffee): 15g
  • Yield (Water/Output): 250g
  • Grind Size: Medium-Fine (Similar to coarse sea salt)
  • Water Temperature: 94°C (201°F) - Hotter water helps extract those bright fruit notes.
  • Brew Time: 2:30 - 3:00 minutes
  • Equipment Note: Set the Ode Brew Grinder Gen 2 to 5.1

Step-by-step Instructions:

  1. Rinse your paper filter with hot water and discard the water. Add your 15g of ground coffee.
  2. 0:00 - Bloom: Pour 45g of water in circles. Swirl the brewer gently and let it sit for 45 seconds to release trapped gases.
  3. 0:45 - First Pour: Pour in slow, concentric circles up to 150g of water.
  4. 1:30 - Second Pour: Continue pouring gently until you reach your total weight of 250g.
  5. Give the brewer one final gentle swirl and let it drain completely.

Rwenzori Dial-in Pro-Tip: Naturally processed Rwenzori coffees can sometimes produce more "fines" (coffee dust) when ground, which might slow down your brew. If your water is draining too slowly, try grinding just a tiny bit coarser next time!
