Green Tea: What the Grade Actually Buys
A hundred grams of leaf, a glass tumbler and water off the boil
The cafe cup replaced by a thermos at the desk
A tea shop counter with a row of tins and a scale.
Green tea is priced by the hundred grams and drunk by the cup, and the cup is where the arithmetic lands.
Prices for green tea arrive in ranges rather than headlines, and the ranges are what a household can plan with.
The cheap version of green tea costs less per pack and more per use, and the per-use number is the one that matters.
Where the money goes
For green tea, the cost splits into 5 lines, and the table is the only honest way to show them.
A hundred grams of green tea makes dozens of cups, and the bottled version costs more per litre than the leaf.
A gift tin of the tea is priced by the tin as much as the tea, and the tin is kept after the tea is gone.
Treat every figure as a typical range, because the same line is a different number in the next city and the next season.
A jar of the tea is priced by the label as much as by the contents, and the label is the part that is marketed.
A cheap pack of the tea is cheap because it is smaller, and the smaller pack usually costs more per gram.
| Line | Typical range | Basis |
|---|---|---|
| Teapot or gaiwan | $30–150 | one purchase |
| Loose leaf, 100 g | $8–40 | typical range |
| Cup at a tea shop | $3–8 | typical |
| Gift tin | $20–80 | typical |
| Bottled tea | $2–4 | per bottle |
A worked example
Take two lines of the tea: loose leaf, 100 g at $8–40 and teapot or gaiwan at $30–150. Together they run $38–190 before anything optional.
That total is the number to budget, and the optional lines are the ones to cut when the month is short.
The sum is the minimum a household should expect, and the minimum is the number that survives a bad month.
The line that moves most in the tea is the material, and the material is priced by the season.
Add the third line, teapot or gaiwan at $30–150, and the minimum rises to $68–340 before anything optional.
| Line | Typical range |
|---|---|
| Loose leaf, 100 g | $8–40 |
| Teapot or gaiwan | $30–150 |
| Minimum total | $38–190 |
What a household gives up instead
Every price for the tea has an alternative next to it, and the alternative is what the household is really choosing between.
The table lists the substitutes, and the cheapest substitute is usually the one that costs an hour rather than a fee.
A household that prices the substitute before the purchase usually finds that the expensive version was buying convenience, not quality.
The price of the tea moves with the season, and the season is not announced on the shelf.
| Alternative | Typical range |
|---|---|
| A bottled iced tea | $2–4 |
| A tea-shop pot | $8–20 |
| A cafe cup | $4–7 |
Six moves that change the number
The order matters less than the first move, which is to know which line is fixed and which is optional.
Store the tin away from light. Tea takes the flavour of the cupboard, and the tea is no exception.
Drink the second infusion. The second pour is the one the leaf was picked for.
Pour out the last mouthful. The bottom of the cup is the bitter part.
Buy the tea by the leaf, not the bag. A bag is a portion, and a portion costs more per cup.
Keep green tea off the boil. Boiling water scalds a green leaf and the cup turns bitter.
Rinse the leaf once. The first pour wakes the leaf and washes the dust.
A household that writes the range down before it shops is already ahead of the one that guesses.
Where does it go wrong?
A fair account of the tea has to include the parts that do not work.
Tea from a thermos stays at a temperature that scalds, and the household should pour into a cup.
The tea is a drink and not a treatment, and a cup is not medicine.
Tea drunk with a meal reduces iron absorption, and a household with anaemia should leave a gap.
Cheap leaves are cheap for a reason, and a bag of dust brews a bitter cup that ends the habit.
A strong cup on an empty stomach sits badly with some people, and the household that drinks it all day should eat first.
The habit is cheap at the low end and expensive at the high end, and an aged cake costs more than a month of coffee.
A household that buys the tea in bulk saves money only if it finishes the pack before it spoils.
The label on the tea lists salt and sugar early, and the order of the list is the honest part.
When to buy
Timing changes the number more than bargaining does.
Buy the tea in the spring, when the first pick reaches the shop and the price is set for the year.
The summer is the season for cold-brewing the cheap leaf, and the winter is the season for the dark roast.
The season sets the price of the tea, and the first week of the season is the cheapest.
The date is the only line in the table that can be moved without buying anything different.
Before you pay
Before paying for the tea, five checks change the total more than any discount.
Date the jar when you open it. An opened jar of the tea has a shorter life than the label suggests.
Keep the receipt for the case. A case of the tea bought on price alone is a case the household may not finish.
Buy the refill. The bottle for the tea is the expensive part, and the refill is the same product.
Read the first three ingredients. Salt, sugar and water lead the label on most versions of the tea.
Buy the staple in the size you use. A sack of the staple behind the tea is cheaper per kilo and a problem if the household does not finish it.
Check the pack size you will finish. Bulk the tea is a discount on storage, and storage is not free in a small flat.
The checks take ten minutes and cover the lines that a table cannot show.
Which household is this for?
The cost falls on the person who books it, and the benefit falls on everyone at the table.
A household with an older parent carries a different version of the bill, and a household with a child carries another.
The table does not change with the household, but the number of lines a household uses does.
A household with children uses a different quantity of the tea from a household of two.
The one line to keep
What the tea costs is the leaf, and the leaf is the only line that a household can choose.

The search for the tea ends with a number, and the number is easier to check than to argue about.
What the tea costs is a range, and the range is small enough to plan a week around.
The imported version of the tea costs several times the local one and does the same job.
The household that prices the tea by the use rather than the pack keeps the grocery bill flat.
The price of the tea splits into what is used and what is thrown away, and a household controls the second half.
