title: "Do You Need a Coffee Canister?"
lead: "Not if you buy only what you'll drink in two weeks — the valve bag it came in, clipped shut in a dark cupboard, is enough. Canisters and freezer storage matter only once you buy ahead of your pace."
recommendation:
  name: "The original valve bag, clipped, plus a two-week buying rhythm"
  reason: "The best freshness tool isn't a container, it's how much you buy. The bag's one-way valve exists to vent the CO2 fresh beans release, and clipped shut in a dark cupboard it keeps two weeks of flavor intact. The day you switch to buying ahead is the day to add an opaque canister or the freezer routine."
