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’m not from the US, but creamer isn’t typically milk, right? It’s some kind of protein-heavy vegetable fat?
Powdered creamer is usually corn syrup solids, others vary. I personally just add a splash of milk to my coffee and sweeten slightly with Splenda (I’m T2 diabetic, no sugar).
