I’m at work on this year’s version of my annual holiday gift guide, but you might first want to check out this primer from coffee god James Hoffmann’s youtube channel. There’s a lot of really good stuff here on what to gift someone into coffee, helpfully segmented in terms of just how much they’re into the stuff as well as price points, and even better is the information about what not to get them.
I might have a very minor quibble with some of the points (opinions, everybody’s got ’em, amirite?), but well worth your time.
