We'd definitely have kidney beans in chili and some other dishes, but I got the impression it was a hassle otherwise.

Friend and I ran a weekly pop-up espresso bar and did a lot of experimenting over the winter. The USAP "house" beans are quite dark, but at least they're roasted within a year or two because coffee is always available and we go through a lot of beans every season. Except the decaf. That stuff is decades old.
People often bring down a big bag from one of the roasters in Christchurch. We personally shipped down a lot of specialty coffee, mostly made V60 and aeropress. The outbuilding where our telescopes live also has a Chemex and an automatic.
There’s other tricks: various beans can be found in the form of instant powder or flaskes (1 min watering - no cooking) semolina (5 min watering - no cooking) and pre steamed (no watering - 10/20 min cooking). I bring those to hike on the mountain and use gaz only to make them hot. Mixed with cereals semolina, spices, herbs and oil/nuts its the perfect submit meal.
