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.
Have you tried black tea? I have heard it has the most amount of caffeine out of all the different types of tea.
I have, and do often drink black tea. Not enough caffeine content though.
Darn, OK.
