This made a pretty good cup. It had no bitterness, and the body and flavor actually seemed better than the pourovers I have been making recently with these beans. I wonder if the cooler ambient air temperature this time of year is affecting the extraction of the pourovers.

I had been wanting to get back to occasionally brewing lighter roasts in the AeroPress, since I’ll likely be doing it a lot while traveling, where I won’t have precise control over the temperature of the water, or access to a scale. This seems like a good first stab. The recipe is very similar to what I’ve been using for dark roasts, but adds a bloom step. I used the scoop that came with my plastic V60 dripper to measure the beans, and also weighed them, and it seems that 16-17 grams translates to one slightly heaping scoop of beans. I’ll have to try this with a couple of different light roasts to see how much variance there is between them. Then, I’ll just need a way to eyeball the amount of water, and I expect that I can use the markings on the AeroPress cylinder for that. The Prismo definitely makes this easier, as it keeps the water from dripping out through the filter without the need to invert the AP.

1/21: I brewed the same recipe today with Zeke’s Holiday Roast (a medium roast) except I dropped the water temperature to 95C. It produced a perfectly OK cup that was neither better nor worse than my V60 cups. I have a feeling it would benefit from a little bit of tweaking, but as I’m almost out of the beans, I’ll likely just go back to V60 to use them up.
