Roastown Coffee: An Inverted Daily Driver

Creator: Sidechain W
I came across this on bilibili, YouTube’s Chinese equivalent.

As an inverted recipe, it hits all the right spots: low-dose, no fuss, time-efficient.  

Jason of Roastown Coffee created this recipe as a response to “championship” recipes. Popularized by WACs of recent years, these recipes typically use high doses (e.g., 30g) and bypass. Although punchier in flavor, they just can't function as daily drivers. 

I always found washed light roasts hard to dial in on the AeroPress, yet Jason’s recipe blew me away.

Recipe Notes:

  • Grind size: In the video, Jason recommends the same grind size as a cupping. For me, a medium-fine grind size works very well; #22-24 on C40 might be a good starting point.
  • Ratio: 1:18 or ~55g/L (same as James Hoffmann’s recipe)
  • Jason also suggests lowering acidity by dropping your water temperature.

I think this recipe can suit a wide range of roasts and processing. For lighter roasts, I always perfer my water straight off the boil. If you are brewing a darker roast, try grinding coarser, using more coffee and lowering your water temperature.

Recipe details:

Paper Filter


Medium (Cupping)
Light Roast


100°C / 212°F


  1. Set inverted AeroPress at full capacity (plunger below ④ marker)
  2. Boil your water, grind 12g of coffee and add to chamber. Pre-wet your filter-cap combo.
  3. Start a timer, quickly add ~216g water in one pour.
  4. Stir continuously until about 0:40.
  5. Twist on cap with filter and let sit.
  6. Optional: Gently swirl the AeroPress a few times to further de-gas, then slowly push out extra air in the chamber. (this makes flipping drip-free)
  7. Flip at 1:30.
  8. Optional: If any grounds are still stuck to the piston/wall, gently swirl to knock off. (this maximizes extraction during percolation)
  9. Press gently all the way, finishing at about 2:00.
  10. Enjoy!
