Regarding the difference between matcha’s first flush and autumn harvest, the key distinctions lie mainly in their delicacy of flavor and aroma.
I. First Flush
Picking time: Early Spring, from March to May.
Features:
• Stronger umami and a more delicate aroma
Spring buds are rich in amino acids, giving matcha a distinctive sweet and fresh taste.
• Brighter, more vibrant green color
Shading and nutrient accumulation during spring allow the tea leaves to develop a vivid emerald-green hue.
• Smoother texture with lower bitterness
Lower tannin content results in a milder, more mellow flavor.
II. Autumn Harvest
Picking time: September to October.
Features:
• More intense aroma but less delicacy compared to spring tea
Amino acids decrease while polyphenols increase, creating a stronger aroma but less sweetness than spring matcha.
• Darker or slightly yellowish-green color
Longer sun exposure and older leaf age make the color less bright.
• More astringent and stimulating taste
Higher polyphenol levels contribute to a stronger, sharper flavor.
Summary
If you prefer a smooth taste with a delicate aroma, first flush matcha is the ideal choice.
If you enjoy a stronger aroma and don’t mind a slightly bitter or astringent taste, autumn harvest matcha is a good option.
