Uji's 2026 First Flush: Record-Breaking Chlorophyll Levels Signal an Exceptional Season
Tea farmers in Uji's Ogura district are reporting the deepest green of the decade — and the science behind the leaves backs them up.
At 5:30 on a May morning in Uji's Ogura district, fourth-generation tea farmer Kenji Morita runs a single leaf between his fingers and nods slowly. "The colour this year," he says, looking for the right word, "is alive."
He is not speaking metaphorically. The 2026 ichibancha — first flush — has produced leaves with chlorophyll concentrations that, when measured by Kyoto Prefectural University's tea research lab, came in 18% above the five-year average. L-theanine content, the amino acid responsible for matcha's distinctive calm-alert effect, was up 12%.
What drove this year's exceptional results
The answer lies in an unusual confluence of weather: a colder-than-average February, which slowed bud development and concentrated nutrients in the remaining leaves, followed by an extraordinarily warm and cloud-filtered April.
"We don't chase records. But when the leaf tells you it's ready to be something special, you listen to the leaf."
What it means for buyers and drinkers
Ceremonial-grade matcha from Uji's top producers will be worth seeking out this autumn. Watch for releases from Marukyu Koyamaen, Ippodo, and smaller single-garden producers in September through November.
