Expiration & Storage Tips
When does matcha expire?
Matcha powder is a delicate ingredient and should be treated with care. Unopened and stored in a cool, dark place, high-quality matcha powder can last up to a year. However, always check the 'Best Before' date printed on the package. Once opened, matcha should be consumed within 2 to 3 months for optimal freshness and flavor. If you store opened matcha in the freezer, it can extend its lifespan for another 2 to 3 months.
How do you tell if matcha is bad?
As matcha powder loses its freshness, it goes through noticeable changes. First, the bright green color turns a dull, brownish green. This color change is due to oxidation and a clear sign that your matcha powder is losing its quality. Also, the fresh, earthy smell will start to fade. If your matcha powder develops an unpleasant, sour or stale smell, get rid of it. Taste is another indicator; fresh matcha tastes smooth and slightly sweet with vegetal notes, while stale matcha tastes bitter.
Tips for storing matcha to extend shelf life
• Store your matcha in an airtight container to prevent exposure to oxygen which can cause it to oxidize and lose its flavor quickly.
• Keep your matcha in a cool, dark place, away from sunlight. Sunlight can cause matcha to oxidize faster and lose its vibrant green color.
• Avoid storing matcha in a spice rack or near a heat source, like above your stove, as heat can accelerate its degradation.
• If you choose to freeze your matcha, ensure it's tightly sealed to prevent any moisture from getting in. Always allow it to reach room temperature before opening to prevent condensation from forming which can affect the quality.
