Matcha is delicate. Light, heat, and air degrade its color and flavor over time. To keep your BrewNova fresh:

• Store it in an airtight container—the original tin is fine if it seals well.
• Keep it in a cool, dark place, like a cupboard away from the stove.
• Avoid the fridge unless the packaging says otherwise. Condensation can cause clumping.
• Use it within 3 to 6 months of opening for the best taste.

If your matcha turns dull brown or smells musty, it's past its prime. Toss it and open a fresh one.
