SO apparently if you add enough instant coffee to make it taste like a "strong" cup of coffee... its gonna contain way more caffiene than you expected. Didn't realize it until my hands wouldn't stop jittering.
It actually tastes pretty good but yeah. Don't be like me. Looks like I'm definitely staying up until midnight.
way more coffee to liquid ratio than suggested.
Sometimes this can be achieved by making a normal pot of coffee and letting the coffee pot sit on a heat source long enough to evaporate a portion of the water but leaving the caffiene sludge behind.
