If you are by car in Monteverde / St. Elena and do not wish to use the taxi/shuttle services or the "help" of people who get a lot of commission, just drive up to San Luis by car. In San Luis you will find the sign (i.e. to the right at the only junction in San Luis) with "Cafe San Luis" which is where the tour is. It starts most often at 8h30 and always at 14h, every day. Without the transport you pay 16 USD per person (and kids for free) for a very interesting tour by the owner, Victor, (and a dolmetscher) and get to taste the best coffee.
He also has explanations about other agricultural things than coffee.
You could check out "victorsfarm" on the internet. (.com) for mor info/telefone nr, etc.
