No one was more serious about how he took his morning coffee than the classical composer Ludwig van Beethoven. He would count out 60 coffee beans every morning. It was this number, he believed, that would make a perfect cup of coffee. Sixty ground beans is roughly equivalent to 8 grams (enough for a decent espresso), though this wasn’t invented until 1884, according to Open Culture. Beethoven used a glass, balloon-style coffee maker of his own invention, which probably looked similar to a modern siphon brewer. But it must have pulled a great cup of coffee because this ritual remained unchanged for the remainder of Beethoven’s short life.
