I use a breville, and a dual wall cup.
Never did get super deep into coffee science, measuring the water/bean ratio with respect to extraction time etc etc. Though maybe I could in the future.
I have access to an entire breville that has a bad motherboard, I've thought about converting it in this way. It would be fun to do, but would I benefit in any way other than the experience of doing it?
What benefits do you personally get from this?
