I buy coffee beans in bulk, fair trade organic. I keep it in the freezer, but even just a few weeks after opening, the flavor of the beans aren't like the zest of the original unsealing of the vacuum sealed bag. I would like something like 1 oz sealed bags of beans that I can buy in bulk. Maybe even larger sizes. That way, every time I grind, I am getting that freshly-opened flavor. Bonus: with smaller bags, you can sell sampler packs, flights, or varieties to people who are looking to sample your blends.
