One of the oldest books about coffee?
Some time ago I wrote about books. (https://steemit.com/books/@andrea.pacini/when-you-read-the-book-last-time)
The book about coffee exists too (I think not even one)
But you look what year of release: 1872.
Book about coffee, State Library of Massachusetts by Hewitt, Robert Jr., 1872.
Read, drink, enjoy.
Peace for everyone!
