How can I visually tell the difference between First Flush and Second Flush matcha?

First Flush matcha has a vibrant, almost neon emerald green color due to high chlorophyll content. Second flush or lower culinary grades appear duller, with yellowish or brownish undertones.

Is culinary grade matcha bad for you?

No, culinary grade is actually higher in catechins (antioxidants). However, it lacks the L-theanine that provides the sweet, calming umami flavor found in Ceremonial Grade, making it too bitter to drink just with water.

Why is Yame Matcha so special?

Yame, located in Fukuoka prefecture, is famous for its morning mists and large temperature variations between day and night. This unique terroir produces matcha with an exceptionally rich, deep umami flavor compared to other regions.

First Flush vs. Second Flush Matcha: Why Ceremonial Grade Matters

The Importance of the Harvest Season

When you purchase matcha, you are not just buying powdered green tea; you are paying for the precise timing and meticulous care of the harvest. The most profound difference in matcha quality comes down to when the tea leaves were plucked: the First Flush (Ichibancha) versus the Second Flush (Nibancha) or later harvests.

What is First Flush (Ichibancha)?

First Flush refers to the very first harvest of the spring, typically occurring in late April to early May in regions like Yame, Fukuoka. After resting throughout the cold winter, the tea bushes store massive amounts of nutrients, amino acids (specifically L-theanine), and natural sweetness.

Only the youngest, most tender shoots at the very top of the shaded tea plants are hand-picked. This results in matcha that is vibrant emerald green, profoundly sweet, rich in umami, and devoid of astringency. This is the only tier that qualifies as true Ceremonial Grade.

What is Second Flush (Nibancha)?

Second Flush is harvested in late June to early July. Because the plant has already expended its stored winter nutrients during the first harvest, these leaves grow faster in the summer heat and contain far more catechins (tannins). This results in a duller, yellowish-green color and a noticeably bitter, astringent taste.

While Second Flush is excellent for culinary purposes (baking, smoothies, heavily sweetened lattes) where its bold flavor can cut through sugar and dairy, it should never be consumed as traditional Koicha (thick tea) or Usucha (thin tea).

The Danger of "Fake" Ceremonial Grade

Unfortunately, because "Ceremonial Grade" is not a legally protected term internationally, many overseas brands package cheap, bitter summer-harvest matcha in luxury tins. At WAGYUNINJA, we source exclusively from award-winning tea estates in Yame, ensuring our premium matcha is 100% First Flush, stone-milled to perfection.
