Matcha powder

Energy: ~320 kcal / 100 g dry (planning figure — the product label is the final reference)

Shelf life: Sealed: months; fades fast once opened — use within a few weeks.

Storage: Sealed, cold, away from light and air — matcha oxidizes quickly.

Sift first, then whisk with water at 70–80°C — never boiling; keep it airtight, cool and dark, and finish the tin within weeks of opening.

Whole-leaf caffeine plus L-theanine — a serving counts fully toward the ~400 mg/day adult caffeine guidance (much lower in pregnancy).
