How much matcha does a cafe use, and how much should you order?
Buyer briefing
What to know
How much matcha a cafe uses is drinks per day times grams per drink, plus a waste allowance for sifting, training, and dose drift. At 3 to 4 grams for a 12 oz latte, a 1 kg bag is about 250 to 330 servings, so a bar pouring 40 matcha drinks a day works through roughly a kilo a week. Set two par levels rather than one: a station tin finished within one month of opening, and a sealed, cold reserve sized to your supplier's lead time. Reorder against total on-hand, not against the tin you can see.
Decision checks
- Weekly use is matcha drinks per day times grams per drink times service days, plus a waste allowance. Weigh the dose, because a scoop swings it 20 to 30 percent.
- A 1 kg bag is about 250 to 330 lattes at 3 to 4 grams. Divide by your drinks per day to get days of cover before you pick any order size.
- Split par in two: a station tin finished within one month of opening, and a sealed, cold reserve. The freshness clock limits how much you open at once, not how much you own.
- Set the reorder point at daily use times your supplier's real lead time plus a few days of safety stock, counted against total on-hand rather than the tin you can see.
How much matcha a cafe uses is arithmetic. Count the drinks you pour in a day, multiply by the grams in each, add a waste allowance, and you have the weekly number behind your par level and your reorder point: big enough that you never stock out, small enough that every drink comes from a bag still inside its freshness window.
How long does a kg of matcha last in a cafe?
A standard 1 kg bag is 1,000 grams. A 12 oz cafe latte uses 3 to 4 grams of matcha, so at 3 grams a cup you get about 330 servings from a single kilo, and at 4 grams about 250. The dose table lives in our matcha latte profit margin guide, the only page that prints it.
Servings become days once you divide by drinks per day, which is where a yield question turns into an inventory question.
How much matcha does a cafe use in a week?
- Count matcha drinks per service day. Pull the POS count for every item that touches matcha, with baked and frozen counted separately.
- Multiply by grams per drink. Use your recipe card. If your 16 oz iced build is your bestseller, your average gram weight is higher than your 12 oz spec suggests.
- Add a waste allowance. Sifting loss, training drinks, remakes, and dose drift come out of the same bag: a scoop swings the dose 20 to 30 percent, so scooping costs more than the recipe says.
- Multiply by service days. Work weekly, not monthly: matcha volume is weekday-weighted, and a monthly average will be short on your busy days.
Worked example, assumed inputs. Say 40 matcha drinks a day at 3.5 grams, six service days a week, with a 10 percent waste allowance used purely as a round placeholder. That is 140 grams a day, 840 grams a week, and about 925 grams once the allowance is on.
That figure, not a price break, sets your order quantity.
Setting a matcha par level and a reorder point
Split the par in two: opened and sealed matcha age on different clocks. Working stock is the tin at the station, sized to roughly a week of that drink’s volume. Once air is in it, plan to finish an opened tin within one month. Sealed reserve is everything you have not opened. Unopened, sealed matcha holds for months. The freshness clock governs how much you open, not how much you own: a deeper reserve costs nothing while it stays sealed and cold.
A 2020 study in Food Science and Biotechnology stored matcha for two months at five temperatures and reported that 4°C was the suitable condition, while at 25°C the authors estimated storage of about seven days (Kim et al.). That is chemistry rather than the cup, but the direction is clear: a warm back bar is where inventory dies. More in our storage guide.
Then set the reorder point: daily use times your supplier’s real door-to-door lead time, plus a few days of safety stock, counted against total on-hand, not the tin you can see.
Two ways cafes get the order quantity wrong
Ordering too much. Oxidation strips the vivid green and the fresh, grassy top notes, leaving a flat, hay-like cup. Regulars will not say the matcha went off; they just order it less. And the better the lot, the more you lose: a single-cultivar Okumidori from Kagoshima, 2026 first flush, is exactly the character oxygen takes first.
Ordering too little. Running dry on a Thursday is harder to fix than it was. Japanese growers have been converting sencha fields to shaded tencha, the leaf matcha is milled from, which tightens supply now while building matcha capacity over the next few seasons. Shizuoka’s 2026 second-flush trading closed at an unprecedented high, up by more than half on 2025, with the tightness attributed to that switch (中日BIZナビ). More in our matcha shortage guide.
Where Hisa fits
For most cafes the freight math decides, not the freshness math: small and frequent is right and impossible when a supplier’s minimum runs to tens of kilos, so cafes over-buy and the end of the bag pays for it.
That is the tradeoff Hisa dissolves. A 1 kg per-lot minimum and stock already sitting in the US mean your order quantity can follow your weekly consumption instead of a container schedule. Reserve stays sealed, the station tin stays inside its window, and a restock is not an import project.
