Storage tips
- Keep diet powder mixes and drink mixes sealed in a cool, dry cupboard after opening to hit the window above. They do not need refrigerating.
- Keep coffee, tea and drink powders airtight in a cool, dark cupboard, away from the kettle and the stovetop. Air, light and damp are what flatten them, not time alone.
How can you tell if diet powder mixes and drink mixes have gone bad?
- Any mold at the neck or under the cap.
- In dry drinks: a stale, flat or musty aroma, or powder that has clumped hard from damp. These fade in quality long before they become unsafe.
