Matcha is famous for its rich flavour and impressive health benefits. However, to enjoy matcha to the fullest, it is essential to store it correctly. Matcha is a delicate product, sensitive to light, air, heat, and moisture; if not stored properly, it can quickly lose its freshness, flavour, and nutrients. In this blog, you will learn how to store your matcha correctly so that you can enjoy it for as long as possible.
Matcha is different from most loose-leaf teas because the powder is consumed directly rather than being steeped first. This means that all the nutrients in the leaves, including antioxidants such as catechins, chlorophyll, and the amino acid L-theanine, remain intact. However, these compounds are sensitive to external factors such as air, heat, and light.
When matcha is exposed to these elements, it can oxidise, leading to a bitter taste, a loss of vibrant colour, and diminished health benefits. Oxidation causes the antioxidants in the tea to lose their effectiveness, preventing you from fully benefiting from its properties, such as increased focus, improved metabolism, and relaxation.
Factors that affect matcha
There are four key factors that can influence the freshness of matcha:
- Air: Exposure to air can rapidly reduce the quality of matcha. As soon as matcha comes into contact with oxygen, the oxidation process begins. This diminishes both the flavour and the nutritional value.
- Light: Direct light can affect the colour of matcha, making it less vibrant green and more dull. This is caused by the breakdown of chlorophyll, the pigment that gives matcha its vivid hue.
- Heat: High temperatures can negatively impact the freshness of matcha. Ideally, matcha should be kept cool to prevent the delicate compounds in the tea from breaking down.
- Moisture: Because matcha is a fine powder, it can easily absorb moisture. This can lead to clumps and a pasty texture. Damp matcha also loses its flavour more quickly.
How to store matcha
Storing matcha properly requires attention to detail, but with a few simple steps, you can maintain its freshness and flavour perfectly.
- Store matcha in an airtight container. Once you have opened your matcha, it is important to keep it in an airtight container. The original packaging is often specially designed to keep air out, so it is a good idea to leave the matcha in there. If you wish to transfer it to another container or pouch, ensure it is airtight, such as a glass or metal jar with a tight seal. This prevents air from reaching the matcha and accelerating oxidation.
- Protect it from light. Light is the enemy of matcha’s bright green colour. Therefore, store your matcha in a dark place or an opaque container. Many matcha tins are made of metal or tinted glass, which helps keep light out. Avoid storing matcha in places with direct sunlight, such as a windowsill.
- Cool, but not too cold. The ideal temperature for storing matcha is cool, but not freezing. A dark, cool cupboard is usually sufficient. If you live in a warm climate or want to store your matcha for a longer period, you might consider keeping it in the fridge. Only do this if the matcha is sealed airtight to prevent it from absorbing moisture from the fridge. Also, ensure you let it reach room temperature after taking it out of the fridge before opening it, to prevent condensation.
- Moisture and matcha do not mix. Moisture is perhaps the greatest enemy of matcha. Even a little water or damp air can cause matcha to clump together and lose its fine texture. This can reduce both the flavour and the quality of the preparation. Always store matcha in a dry environment and close the packaging tightly immediately after use.
How long does matcha stay fresh?
Matcha is at its best within a few weeks of opening. Although it does not spoil quickly, the flavour and colour can fade over time. Ideally, you should use matcha within 1 to 2 months of opening to enjoy the optimal taste and benefits. Unopened matcha can usually stay good for up to a year, provided it is stored in a cool, dry place.
Tips for using matcha
- Use a clean spoon: Every time you use matcha, ensure you use a clean, dry spoon. Dirt or moisture can affect the quality.
- Buy small quantities: Instead of buying large amounts of matcha at once, consider buying smaller portions and using them up more quickly.
Storing matcha is simple as long as you take the factors that affect its freshness into account. Keep your matcha protected from air, light, heat, and moisture, and you will be able to enjoy its rich flavour and health benefits for a long time.
