Brew Basics

Use water just off the boil (around 95°C / 203°F). Measure 2–3 g (≈ 1 tsp) of dried Cyperus rotundus per 250 ml (1 cup) of water. Steep for 5–7 minutes, then strain. For a second steep, increase time by 1–2 minutes. This herb can be enjoyed hot or cold, with optional additions like a small piece of ginger or a cinnamon stick to complement its warm, earthy profile.

Brew log

• 4 minutes: Light aroma, mild earthy flavor, slightly astringent.
• 6 minutes: Richer aroma, deeper earthiness, subtle spicy warmth.
• 8 minutes: Stronger flavor, more pronounced bitterness, lingering finish.

Taste/Use Tuning

If the brew tastes too bitter, reduce steeping time or add a natural sweetener like honey. To soften astringency, blend with milder herbs such as chamomile or lemongrass.

Rituals

• Enjoy a warm cup mid-morning to gently support focus and calm.
• Use as part of a quiet evening ritual to unwind without caffeine.
• Combine with other earthy herbs in a mindful tea ceremony emphasizing connection to nature.
