The Story
The matcha that teaches you to slow down
Most mornings are rushed. Sei Jaku was made for the ones that aren't — or for the ones you decide to rescue. When our 4th-generation master turned his attention to this premium grade, he chose patience above all else.
"Stillness isn't the absence of flavor. It's flavor that makes you stop talking."
Twelve months of aging under controlled conditions mellow the sharpness of fresh matcha and coax forward the sweeter, deeper notes. The result is a cup that asks something of you — and rewards you fully for giving it.

Coffee
Replacing your morning coffee with matcha doesn't mean giving something up — it means upgrading what energy feels like. No crash. No jitters. Just clear, sustained focus, backed by 80 years of Japanese mastery.
Matcha
Matcha combines caffeine with L-theanine — an amino acid found almost exclusively in shade-grown tea. Together they produce calm, sustained alertness without the adrenaline spike.
L-theanine promotes alpha brain wave activity — the same relaxed-but-focused state experienced in meditation. Your mind stays sharp. Your body stays still. No jitters, no anxiety.
Rich in EGCG catechins — the most potent antioxidant in green tea. One bowl of matcha contains the equivalent of 10 cups of brewed green tea in antioxidant value.
Coffee
Coffee delivers caffeine alone — a rapid, sharp spike in alertness followed by an equally sharp drop. The well-known "coffee crash" typically hits 2–3 hours after your cup.
A standard cup contains 80–100mg of caffeine with no L-theanine to buffer it. For many people this means jitters, anxiety, and heart palpitations — particularly on an empty stomach.
Coffee has significant acidic and addictive properties. Regular consumption can contribute to dependence, disrupted sleep, and reduced morning cortisol response over time.
