I like espressos (especially mochas) but they take a bit of work to prepare a single cup. With drip brew, I can do very little and get unhealthy amounts of caffeination into my corpse. Also, I pour ungodly amounts of creamer into my coffee. That Mason jar is quite literally half coffee half creamer.
It’s just kinda how the regular old Mr Coffee machines work, but you boil the water in a kettle and pour it on top all at once. So it’s pourover with a drip throttle.
