Two claims to retire
White tea attracts two claims that do not survive contact with the leaf.
The first is that white tea contains no caffeine at all.
It contains less than some teas, and it does not contain none.
Caffeine sits in the leaf regardless of how gently that leaf was handled.
A bud heavy Silver Needle is made from exactly the young leaf that holds the most.
So the mildest looking white tea is often among the stronger ones in the cup.
The second claim is that white tea and yellow tea are the same thing.
They are not, and the difference is a deliberate process step rather than a shade of colour.
White tea is withered and dried, and that is the whole method.
Yellow tea adds men huang（闷黄）, a wrapped damp stage that changes the leaf.
One category is defined by doing almost nothing, and the other by doing one slow thing.
Confusing them is rather like confusing a dried herb with a pickled one.
Why they persist
These claims persist for the same reason every tea myth does, which is brevity.
White tea has no caffeine fits on a label, and the qualified version does not fit anywhere.
White is just yellow needs no explanation at all, while correcting it takes a paragraph.
Retailers repeat the short version because the long one loses the customer’s attention.
Writers repeat it because the previous writer did, and nobody goes back to the maker.
There is a grain of truth in both claims, which is precisely what makes them stick.
White tea is often brewed weakly, which does produce a light cup that feels caffeine free.
White and yellow teas are both mild, both rare and both pale in the glass.
The error sits in the words no and same, and those are the words that get repeated.
A myth with a true centre is much harder to remove than a pure invention.
The boring fix is to ask what the maker actually did to the leaf.
That question has a real answer for every white tea, and myths dislike real answers.
How to check any claim
Checking a claim about white tea means naming the variable it quietly ignores.
Almost every false rule about this category rests on the colour of the liquor.
Colour tells you about oxidation, and it tells you nothing about caffeine or sweetness.
The variables that matter are cultivar, picking standard, withering time and brewing.
Fuding Dabai（福鼎大白）and a Zhenghe landrace give different cups from one method.
A bud only picking and a bud with two leaves are different teas before drying begins.
Withering runs for 24 to 48 hours in most working systems, and the end point is judgement.
Then brewing decides the rest, since 3 g at 85 °C and 5 g at 95 °C are not comparable.
Change one of those at a time and hold the others, and the picture clears quickly.
Two cups brewed side by side from one leaf will settle most arguments in a few minutes.
That is the whole method, and it needs nothing beyond two vessels and a thermometer.
A claim that cannot be tested this way is not really a claim about tea at all.
The honest baseline
The honest baseline for white tea is shorter than the myths and harder to sell.
White tea is withered, not oxidised, not yellowed, and not uncaffeinated.
It is usually gentle in the cup at 3 g in 150 ml and 85 °C for 3 minutes.
It can be strong, grassy and distinctly brisk when the leaf is young and the water is hot.
Those two sentences cover most of what a buyer actually needs to know.
What they do not do is fit on a label, which is the real reason the myths survive.
The practical habit is to treat any absolute claim about this category as a question.
Ask what was done to the leaf, and ask what water the seller would use themselves.
A shop that answers both in specific terms is worth returning to.
One that repeats the slogan is selling a story rather than a tea.
Storage matters as well, since white tea changes over years and the myths ignore that.
A tea that was true at one year may not be at five, and that is a feature, not a fault.
