Two claims to retire
Red tea comes with two claims that push brewers towards the same bad cup.
The first is that it must be brewed with boiling water and left there for a long time.
Boiling water suits a sturdy broken leaf, and it ruins a fine bud heavy Dianhong.
A golden tip tea brewed at 100 °C for 5 minutes turns bitter and stewed.
Most modern Chinese red teas do better at around 90 °C with a shorter steep.
The rule was written for a different leaf entirely and then never revised.
The second claim is that red tea gives you one infusion and nothing after it.
A good one gives three decent pours, and often more from a whole leaf grade.
What kills it after the first cup is usually the water rather than the leaf.
Scalding the leaf extracts everything at once and leaves nothing behind for later.
Lower the temperature and the same tea spreads itself across a whole session.
Both claims come from the habit of using one setting for an entire category.
Why they persist
Both claims persist because they produce a strong cup, and strong reads as correct.
A dark, bitter, over extracted brew looks like exactly what people expect red tea to be.
Nobody sends that cup back, so the method that produced it never gets questioned.
Shops teach it because a strong first cup sells better than a balanced second one.
Writers repeat it because the previous writer did, and few people brew side by side.
There is also an industrial history behind the rule, and it is worth naming.
Broken grades were developed for tea bags and for milk, and boiling water suits them.
Whole leaf Chinese red teas arrived in most markets much later and inherited the rule.
The rule was never wrong for the leaf it was originally written for.
It is simply wrong for a bud heavy Yunnan tea or for a light Keemun.
The fix is to ask what grade the leaf is rather than what colour it brews.
Grade tells you the water temperature, and colour tells you nothing useful at all.
How to check any claim
Checking a claim about red tea starts with the leaf grade and the water.
Grade describes how much of the leaf was broken during rolling.
Broken leaf gives up its material quickly, and whole leaf gives it up slowly.
That single difference sets the temperature and the time more than anything else does.
Hotter water suits a broken grade, and cooler water suits a whole leaf one.
Time follows from both, and 3 minutes is a fair starting point for most of this category.
Dose is the last variable, and 4 g in 150 ml is the standard working ratio.
Change one of those at a time and the whole category becomes predictable.
Then run the milk test, since a great deal of this tea is drunk that way.
A tea that keeps its body under milk has the material to be worth buying.
One that thins out to coloured water was never going to survive a second infusion either.
Those two tests take a quarter of an hour between them and settle most disputes.
The honest baseline
The honest baseline for red tea is narrower than most people expect it to be.
Most Chinese red teas want 90 to 95 °C rather than a full rolling boil.
Most want 3 to 4 minutes rather than five, and most will give 3 infusions.
A broken grade is the exception, and it can take boiling water without any complaint.
Those three sentences replace the two claims entirely, and they are easy to act on.
What they require is knowing the grade, which is something the seller should state.
Ask whether the leaf is whole or broken, and ask for a water temperature.
A shop that answers both specifically is worth buying from.
One that says boiling water for everything is describing tea bags, not this tea.
Brew the first cup at 90 °C, and raise the temperature only if the cup comes out thin.
That one adjustment improves most red tea more than any change of leaf would.
It is a small habit, and it is the difference between tolerating a category and enjoying it.
