Edwin Martinez is not only the US representative of the Hario products, he's also a third-generation coffee farmer from Guatemala. While we visited him last month, he talked to us about a coffee processing experiment that he undertook with some of his roasting customers who were looking to change the base flavor of the coffee before they got their hands on it. This video covers the experiment and talks about coffee processing in general, as well as how what is done to the coffee at the plantation effects the end flavor of what will end up in your cup.
