How long does matcha last after opening?

Opened matcha stored in an airtight container in a cool, dark cupboard is at peak flavor for 4 to 6 weeks. It remains drinkable for up to 3 months, but the color and flavor degrade. Buy in quantities you will use within 4 to 6 weeks.

Should you refrigerate matcha?

Generally no. Refrigerator storage risks condensation damage every time you open the container. Store in an airtight container in a cool, dark cupboard instead. If you must refrigerate, use a completely airtight container and let it reach room temperature before opening.

Can you freeze matcha?

Yes, if the container is completely airtight. Divide into small portions, freeze in airtight containers, and let each portion reach room temperature completely before opening to prevent condensation. See /learn/storage/how-to-store-matcha for the full freezing guide.

How do you know if matcha has gone bad?

Check the color -- fresh matcha is vivid bright green. Degraded matcha turns dull olive or yellow-green. Also check the smell: fresh matcha smells grassy and sweet; degraded matcha smells flat or musty. Degraded matcha is not harmful but produces a weak, bitter drink.

What is the best container for storing matcha?

An opaque tin with a tight-fitting lid is best -- it blocks light and minimizes air exposure. Most quality matcha comes packaged in these. Dark glass jars with airtight lids also work. Avoid clear containers and loosely sealed bags.

How to Store Matcha: Shelf Life and Freshness Guide

Store matcha in an airtight container away from light, heat, and moisture. Use within 4 to 6 weeks of opening for peak flavor. Unopened matcha lasts 12 to 24 months. Do not refrigerate unless the container is completely airtight -- condensation degrades matcha quickly.

The four enemies of matcha freshness

Matcha degrades from four things: light (breaks down chlorophyll), heat (accelerates oxidation), moisture (causes clumping and oxidation), and air (oxidizes catechins and chlorophyll). Store matcha in an opaque, airtight container in a cool, dark cupboard to protect against all four.

For the complete storage guide including shelf life tables, freezing instructions, and how to tell if matcha has gone bad, see /learn/storage/how-to-store-matcha.

Storage Condition	Shelf Life After Opening
Airtight tin, cool dark cupboard (ideal)	4 to 6 weeks peak; up to 3 months drinkable
Airtight container, refrigerator	Up to 3 months (condensation risk)
Airtight container, freezer	Up to 6 months (must be completely airtight)
Loose bag, room temperature	1 to 2 weeks before noticeable degradation
