Tea Brew Guide

Steep It Right — Hot, Iced, or Cold Brew

Hey — Bert here. Tea shouldn't be complicated. These are the exact temps, times, and ratios we use — written so you can glance at it mid-brew and get on with your day.

A friendly, no-stress cheat sheet for every tea type. Whether you're steeping a single cup or brewing a gallon for the fridge — start here, trust your taste, then adjust from there.

The Don't-Overthink-It Method

A kettle and a timer is all you need. Use fresh water, pre-warm your mug, and let the chart below do the thinking.

Two Rules That Fix 90% of Bad Tea

Most tea problems come down to two things: wrong temperature, or too long a steep. Get those right and everything else is a bonus.

Bitter tea? Water was too hot or steeping time was too long. Lower the temp by 10–15°F or pull the tea 30 seconds earlier.

Weak tea? Not enough leaf, or not long enough. Add a little more tea before you extend the steep time — it's faster.

Flat tea? Start with fresh cold water. Stale or re-boiled water strips all the brightness out of the cup.

Per 8 oz / 240 ml

Easy Ratios

  • Black Tea 1–2 tsp
  • Green Tea 1–1½ tsp
  • Herbal / Tisanes 1–2 tbsp
  • Rooibos 1½–2 tsp
  • Matcha (powder) 1–2 tsp
  • Oolong 1–2 tsp
  • White Tea 1½–2 tsp

Have a scale? Most teas land around 2–3 g per 8 oz. Herbals can be more — they're fluffy.

Hot Tea — Times, Temps & How Much Leaf

Use this as your starting point, then dial in based on your tea and your taste. These ranges are intentionally wide — work from the gentler end first.

Tea Type Water Temp Steep Time Leaf per 8 oz (240 ml) Bert's Notes
Black Tea 200–212°F 93–100°C · Full boil OK 3–5 min 1–2 tsp Shorter = smooth and bright. Longer = bold and brisk. Bitter? Drop temp a touch or pull it 30 sec earlier.
Green Tea 160–180°F 71–82°C · Never boiling 1–3 min 1–1½ tsp The most temp-sensitive tea. Grassy or sharp? Cool the water + cut time. Cooler = sweeter, smoother cup.
Oolong 185–205°F 85–96°C 3–5 min 1–2 tsp Hotter for roastier, darker oolongs. Cooler for lighter, floral ones. Can be re-steeped 2–3 times.
White Tea 170–185°F 77–85°C 2–4 min 1½–2 tsp Delicate and very forgiving. Use more leaf if it's not "showing up" in the cup — it needs volume to bloom.
Herbal / Tisanes 200–212°F 93–100°C · Go hot 5–8 min 1–2 tbsp Herbals love time and heat. Cover while steeping to trap the aromatics — otherwise they just steam off into the air.
Rooibos 200–212°F 93–100°C 5–7 min 1½–2 tsp Nearly impossible to ruin — naturally caffeine-free. Longer steep brings out deeper vanilla and caramel notes.
Matcha 160–175°F 71–79°C · Never boiling Whisk 15–30 sec 1–2 tsp (powder) Sift if clumpy. Use cooler water for sweeter, smoother matcha. Hotter water makes it grassy and bitter fast.

Bert's reminder: These ranges are starting points — not rules. Your water hardness, your kettle, the age of your tea all matter. Start gentle, taste it, then adjust. That's the whole game.

Beyond Hot Tea

Iced Tea, Sweet Tea & Cold Brew

Three methods, three totally different results. Pick the one that matches your mood — or your fridge situation.

Quick & Bright

Iced Tea

Brew it hot, chill it fast. This keeps flavour lively and avoids flat "fridge tea" syndrome.

  1. Brew at normal hot-tea strength using the chart above.
  2. Fill pitcher with ice — about half your final volume.
  3. Pour hot tea directly over ice, stir, then top with cold water to taste.
  4. Citrus, mint, or sliced fruit? That's "summer porch" territory. Do it.

Cloudy or harsh? Brew a little cooler and shorter — especially for green tea. It hates hot + fast + ice.

1 Gallon Fridge-Ready

Sweet Tea

A practical starting recipe — tea-forward, not sugar-forward. Adjust sugar to your crowd.

  • Tea: 6–10 black tea bags (or 18–30 g loose)
  • Hot water: 1 quart (4 cups)
  • Steep: 4–6 minutes
  • Sugar: Start ¾–1 cup, adjust from there
  • Finish: Cold water + ice to fill a 1-gallon pitcher

Clean sweetness trick: Dissolve sugar in the hot concentrate, then dilute. Sweetens evenly — no gritty bottom.

Ultra Smooth

Cold Brew Tea

No heat needed. Best for greens, whites, and anything that turns bitter when brewed hot. Silky, complex, naturally sweet.

  • Ratio: 1–2 tsp per 8 oz (or 10–20 g per litre)
  • Water: Cold, filtered if you have it
  • Time: 6–10 hours in the fridge (herbals can go longer)
  • Finish: Strain, chill, drink within 2–3 days

Why it works: Cold extraction pulls sweetness and complexity without triggering the bitter compounds heat releases.

Fix It Fast

Troubleshooting — When Something's Off

Nine out of ten tea problems come down to temp, time, or ratio. Here's how to fix all three before you give up on a tea you might actually love.

☹ Too Bitter

Heat and time are the usual suspects.

  • Lower the water temp by 10–15°F
  • Shorten steep time by 30–60 seconds
  • Use a little less leaf
  • For green tea — never use boiling water
Especially: green & black tea

? Too Weak

Your tea isn't getting enough room to express itself.

  • Add a little more leaf before extending time
  • Make sure water is at the right temp (especially for black & herbal)
  • Steep a little longer — particularly herbals
  • Check your leaf isn't stale or old
Especially: herbal & white tea

? Tastes Flat

Something's killing the brightness before it gets to you.

  • Always start with fresh, cold water
  • Never re-boil water — it goes flat and loses oxygen
  • Cover while steeping to keep aromatics in
  • A squeeze of lemon or pinch of salt can brighten it up
