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.
I use the Clever for loose tea to save on cleanup. I buy Ceylon and Assam from various places to make my own blends but nothing ever seems to quite match up to Twinings, dunno what magic they’re doing.
