Brew Earl Grey at 95°C / 203°F for three to four minutes. That is the answer if you are short on time. The longer answer — what kind of water, how much leaf, how to handle the bergamot, and what to do if you want it iced or with milk — is in the rest of this piece.
The fundamentals
Earl Grey is a black-tea blend. Black tea wants hot water, but bergamot oil is volatile and does not survive prolonged extraction. The combination means a relatively short steep at high temperature, and almost nothing else.
| Variable | Setting |
|---|---|
| Water temperature | 95°C / 203°F (just before a full boil) |
| Leaf | One sachet, or 1 heaped teaspoon (~3g) loose, per 8oz cup |
| Steep | 3 minutes for a lighter cup, 4 for a stronger one |
| Maximum steep | 5 minutes — beyond this the bergamot collapses and the cup goes bitter |
| Water | Filtered, fresh, low mineral content |
If you remember nothing else: water just off the boil, three to four minutes, no longer.
Why temperature matters
Below 90°C, black tea does not extract its full body and the cup tastes thin. Above 100°C — say, water that has boiled and been kept at a rolling boil for a minute — the bergamot's top notes vaporize before they reach your nose. The narrow window at 95°C is the sweet spot: hot enough for the leaf, gentle enough for the oil.
The simplest way to hit it is to bring the water to a full boil, then let it sit for thirty seconds before pouring. Or use a kettle that holds temperature.
Why time matters
Black tea steeped for three minutes gives a balanced cup. Pushed to four, it gains strength but loses some of the floral lift; pushed to five, the tannins flatten the bergamot entirely. The signature of a well-brewed Earl Grey is the back-of-the-mouth lift from the bergamot — losing that is losing the cup.
Use a timer. Three minutes is short enough that the difference between three and four matters. Do not eyeball it.
Water
Use filtered water with a low total dissolved solids (TDS) reading. Hard tap water — high in calcium and magnesium — combines with the tannins in black tea to produce a dull, flat cup with a film on top. Reverse-osmosis water or a Brita-filtered cup will give you a noticeably cleaner result.
What you are aiming for is roughly 50–150 ppm TDS. Bottled spring water hits this naturally. London tap water does not (London is famous for being the worst city for tea brewing, despite its tradition).
Leaf format
Whole-leaf Earl Grey gives a noticeably better cup than dust-grade tea bag tea. The leaves expand fully, the bergamot oil distributes evenly, and the steep is even.
- Pyramid sachets with whole leaf — what we use in the box. Convenient, accurate, no mess.
- Loose leaf in a strainer or pot — gives the most even cup. One heaped teaspoon per 8oz.
- Standard tea bags — generally fine but the leaf is dust-grade. Steep for the lower end of the time range; the surface area is much higher.
The serious method (loose leaf)
- Heat the pot. Pour boiling water into the empty pot, swirl, and tip out. This pre-warms the pot so the brewing water does not lose temperature.
- Measure the leaf. One heaped teaspoon (~3g) per 8oz / 240ml of water.
- Heat the water to 95°C. Boil, then wait 30 seconds.
- Pour, then time. Three minutes for a lighter cup, four for stronger. Set a timer.
- Strain and pour. Pour into the cup; do not let leaf sit in the pot or it keeps extracting.
With milk
Earl Grey with a small splash of milk is a perfectly classical British morning cup. A few notes:
- Use whole milk, not skim. Skim milk's extra water dilutes both tea and bergamot.
- Splash, do not pour. The bergamot is delicate; too much milk will obliterate it.
- Brew slightly stronger — closer to four minutes — to compensate for the dilution.
- Milk first or tea first is a debate British grandmothers have settled in opposing directions; the honest answer is that for hot brewing, tea first is fine.
Iced Earl Grey
Two methods:
- Hot brew, ice down. Brew at double strength (two sachets per 8oz, or 6g loose). Steep three minutes. Pour over a glass of ice. Add a slice of lemon. Drink immediately.
- Cold brew. One sachet or 1 teaspoon per 12oz of cold water. Steep in the fridge for 8–12 hours. Strain. Less assertive than hot-brewed-iced, but smoother and lower in tannin.
Iced Earl Grey with lemon and a touch of honey is one of the better summer drinks in the canon. Iced Earl Grey with milk (a "London Fog" served cold) is also surprisingly good if the milk is whole and the brew is strong.
The London Fog
Brew Earl Grey at four minutes. Steam (or microwave) milk to hot. Combine 50/50. Add a small dash of vanilla syrup if you want it; some prefer a small spoonful of honey instead. The whole thing should taste like Earl Grey rounded out with milk-vanilla, not like a flavored latte. Restraint is the difference between the genuine version and the syrupy coffeeshop interpretation.
What not to do
- Do not boil it. Vigorous boiling water destroys the bergamot's top notes.
- Do not over-steep. Five minutes is the absolute outer edge. Past that, the cup goes bitter.
- Do not re-steep most Earl Greys. The bergamot oil mostly extracts on the first pour. A second cup from the same leaf will taste of plain black tea.
- Do not microwave-brew. Microwaving denatures the bergamot and gives a flat, slightly off cup.
- Do not add lemon to a hot Earl Grey with milk. The lemon will curdle the milk. Lemon is for the iced or non-milk versions.
FAQ
What temperature is best for Earl Grey?
95°C / 203°F. Just below a full rolling boil. Higher temperatures vaporize the bergamot oil before it reaches the cup; lower temperatures fail to extract the body of the black tea.
How long should Earl Grey steep?
Three to four minutes. Three for a lighter, more floral cup; four for a stronger, milk-friendly cup. Five minutes is the absolute maximum before the bergamot collapses and the tannins take over.
Can you re-steep Earl Grey?
Generally no. The bergamot oil — which is the entire point of the cup — extracts almost entirely on the first pour. A second steep gives a flat black tea, not Earl Grey. (Some Chinese-base Earl Greys give a usable second pour, but the rule is to make the first one well and stop there.)
Is it OK to drink Earl Grey black?
Yes — and a well-made Earl Grey is best black. Milk masks the bergamot. Use milk only for stronger, breakfast-style cups; for the floral expression, drink it straight.
How much caffeine is in a cup of Earl Grey?
Roughly 40–60 mg per 8oz cup, depending on steep time and base tea. About half an espresso. Suitable for morning and early afternoon; we'd switch to hōjicha in the evening.
