Simple ratios, friendly temps, dreamy cups — hot, iced, lattes & cold brew.

These are great starting points for Coo Coo’s Coffee teas (sachets or loose leaf). Adjust to taste — Bert believes in happy tweaks.

Bert: For most teas, start with 1 sachet per 8–12 oz (240–350 ml) or 2–3 g loose leaf. If it’s too strong, shorten the time before lowering the temp.

Quick Calculator

Use 1 sachet or 2.5 g loose leaf per cup. 200–212°F • 3–5 min

Iced & Cold Brew

Hot-Brew Iced Tea (Quick)

  1. Double the tea: 2 sachets (or 5–6 g) per 8 oz.
  2. Steep with hot water using the hot guidelines above (2–4 min for green/white; 3–5 min for black/oolong; 5–7 for herbal).
  3. Sweeten if desired, then pour over a tall glass packed with ice.

Bright, aromatic, ready in minutes.

Cold Brew (Ultra Smooth)

  1. Use 1 sachet or 3 g per 8 oz (240 ml) cold water.
  2. Steep in fridge:
    • Green/White/Oolong: 6–12 hr
    • Black/Herbal/Rooibos: 8–12 hr
  3. Strain/remove sachets. Serve over ice; keep refrigerated (24–48 hr).

Lower bitterness, super refreshing.

Bert approves lemon in iced tea

Lemon clarity trick: For iced tea, add ~⅛ tsp (a few drops) of lemon juice per 8–12 oz while the tea is still warm. It brightens flavor and helps keep the tea from turning cloudy when chilled.

Tea Lattes (Cozy Mode)

London Fog (Earl Grey)

  1. Steep 2 sachets Earl Grey in 6 oz hot water at 200°F for 3–4 min.
  2. Steam/froth 6–8 oz milk (dairy or oat).
  3. Combine; add vanilla + honey to taste. Optional: lavender sprinkle.

Rooibos “Fog” (Caffeine-Free)

  1. Steep 2 sachets rooibos in 6 oz boiling water for 5–7 min.
  2. Steam/froth milk; sweeten with honey or maple.
  3. Great with our Creamsicle Smoothie or vanilla-leaning herbals.

Chai (Stovetop)

  1. Simmer 2.5–3 g chai (or 2 sachets) in 4 oz water for 5–10 min.
  2. Add 4–6 oz milk; return to a gentle simmer, then strain.
  3. Sweeten to taste. Cinnamon on top = chef’s kiss.

Matcha Latte

  1. Sift 2 g matcha. Add 2–3 oz water at 175°F.
  2. Whisk until frothy; top with 6–8 oz steamed milk.
  3. Sweeten lightly (honey or simple syrup).

Dial-In Troubleshooting

Too Bitter

  • Use a lower temp (esp. green/white).
  • Shorten time by 30–60 sec.
  • Use a bit less leaf.

Too Weak

  • Steep longer (add 30–60 sec).
  • Use more leaf or a second sachet.
  • Cover your mug/teapot while steeping to keep heat.

Water matters: If tea tastes flat or harsh, try filtered water. Cooler water for greens/whites preserves sweetness and avoids bitterness.
