I used to cup 200 coffees a week as a Q Grader for a specialty importer in Seattle. Every sample got scored for acidity, body, flavor — but nobody was tracking the milligrams. I was consuming caffeine all day, every day, and I had no idea what it was doing to my sleep.

When I left the industry to get my master's in food science at WSU, I started studying caffeine metabolism for real. I learned about CYP1A2 — the enzyme that breaks down caffeine — and discovered I am a slow metabolizer. That means 200mg hits me like 400mg hits a fast metabolizer. No wonder I could not sleep.

I built CaffeineCheck because most people have no idea how much caffeine they are actually drinking. A Starbucks Grande Blonde Roast has 360mg — nearly the entire FDA daily limit in one cup. Cold brew can hit 200mg+ per 16oz. Energy drinks are marketed to teenagers who have no concept of half-life.

This site treats caffeine like the drug it is: useful, but dose-dependent. Every tool is built with lab-verified data, pharmacokinetic models, and a healthy respect for sleep architecture.

I live in a converted warehouse loft in Capitol Hill with my partner Sam, who drinks tea and thinks my obsession with milligrams is "endearing but exhausting." Our cat Espresso sleeps 20 hours a day and has never had a sleepless night in his life. I am trying to learn from him.
