This has yielded pretty good results with a couple of different dark roasts. It is adapted from An AeroPress Recipe by Tim Wendelboe. The following seems to work well as a starting point:
- Brew ratio of 1:12.5, which works out to 18g coffee with 225g water or 20g coffee with 250g water. The latter is about the max capacity of the AeroPress+Prismo without using bypass water.
- Water at 85°C
- Steep time of 1:30 to 1:40
- JX grind setting 12 to 16 (36 to 48 clicks)
- Use an insulated mug like a Hydro Flask, with a lid
- Set AeroPress up in standard orientation with Prismo and metal filter. Optionally, add a paper filter in front of the Prismo filter for a “cleaner” cup
- Add ground coffee
- Start timer and add all of the water, finishing at around 0:35, and stir several times back to front
- Cover AeroPress to minimize heat loss. I typically use whatever is on hand, such as the lid for my mug. I don’t use the plunger for this when brewing with the Prismo.
- Steep the coffee– e.g., if the pour took 0:35 and we are steeping for 1:35, then steep until the timer reads 2:10.
- Stir several times back to front again
- Insert plunger and press slowly, using just enough pressure to keep the Prismo valve open
- Put lid on mug immediately to retain heat
