The first sip hitting my throat burns right through me, firey brown bubbles from a nuclear fridge. The second sip, a pleasure, a sweetened soup of caramel (E 150d) colour. The third sip, I hold it in my mouth for a while, unable to swallow, my teeth coated in acid, the caffeine beginning to infiltrate my mind. The fourth time, I'm not sipping, just pouring the crushed petrified wood straight down my throat, I can't stop.
