Every man is a borrower and a mimic, life is theatrical and literature a quotation.
- Ralph Waldo Emerson
At lunch last weekend I overheard someone at another table say that when she wanted a greater caffeine buzz, she chose a different roast. I can’t remember whether she chose darker or lighter roast for the greater buzz, but it doesn’t matter; both answers were wrong. The effect of coffee roasting on caffeine content is so negligible as to be immeasurable except under tightly controlled laboratory conditions.
