coffee aficionados tend to have lots of random bulky objects in the kitchen anyways. coffee makers,coffee implements, temperature sensors etc etc

it quickly becomes a hassle to stow it all away everytime so you end up chucking it all in one "space"

Coffee aficionados don't want to be restricted to buying from a single, web-based company. Unless this company stocks hundreds or thousands of varieties.

anecdotally i'd say that coffee people tend to buy excessive amounts of the one coffee brand they like, they mess around and buy a lot of samples/get gifts but they only have one or two blends that they really like
