A matcha supplier backup plan is a one-page plan for two bad days: the day a lot isn't fit to pour and the day a shipment doesn't arrive when it should. It holds four things: days of matcha on your shelf, a first-24-hours routine for a bad lot, a rule for who approves a substitute, and a second supplier you've already tested. I wrote this one for cafe owners and managers, in the order the bad day happens.
This is the "what now?" half of the job. For the planning half (forecasting, grade mix, a fallback supplier), see my supply security playbook. To check a supplier before you order, use my ten-check supplier list.
Key Takeaways
- Keep a reorder point, not a feeling: the matcha you use between order and door, plus a week of slack. For the made-up cafe below (50 drinks, 180 g a day, a 10-day lead time) that comes to about 3 kg.
- A failed lot shows up on paperwork, in the cup or in a lab. Stop pouring if you're in doubt, keep the bag, and tell your supplier the same day with the lot code and a photo.
- A substitute is a different lot. Get it named in writing, taste it before it ships, and approve it yourself.
- Test a second supplier in a calm week, so you already trust the backup when you need it.
What goes into a matcha supplier backup plan?
A backup plan has four layers, and you reach for them in order: cover, triage, substitute, second source. Each one buys time for the next.
- Cover. Days of sealed matcha on the shelf, with a number that tells you when to reorder.
- Triage. What you do in the first 24 hours with a lot you doubt.
- Substitute rule. Who may swap your lot for another, and what has to happen first.
- Second source and menu fallback. A tested backup supplier, and a way to keep the menu honest while you wait.
The reorder numbers, the days-of-cover zones and the checklists below are my own starting points, not industry standards. Change them to fit your bar.
How many days of matcha should a cafe keep on hand?
Keep enough matcha to cover the time between ordering and the box arriving, plus a week of slack. Inventory courses call that the reorder point: reorder point = daily demand x lead time + safety stock (University of Kentucky, Inventory Management). When your stock falls to that number, you order.
How do you work out daily grams and lead time?
Here is a made-up cafe, so swap in your own numbers. It pours 40 lattes a day at 3 g and 10 large iced drinks at 6 g, which is 120 g plus 60 g, or 180 g of matcha a day. Our 3 g house shot guide sizes drinks the same way, in whole shots of 3 g.
Plan on 10 days from order to door. Our in-stock Latte Grade (Organic) and Ceremonial (Organic) ship from US inventory in 2 to 3 business days with no customs entry, and your written quote confirms the lead time. Our shipping policy lists Standard Shipping at 3 to 5 days. Those two add up to about eight days at worst on paper, and two more days cover a weekend in the middle.
That 10 days is for in-stock matcha. If you buy a made-to-order run from Japan, use 4 to 6 weeks (28 to 42 days) from deposit to shipment-ready, plus transit, as your lead time, and run the same sum.
Days of cover is grams on hand divided by grams used a day, and it is the one number I'd put on the wall by the scale. In the made-up cafe, 10 days at 180 g is 1,800 g and a week of slack adds 1,260 g, so the reorder point is 3,060 g, about 3 kg or 17 days of matcha.
Is a 17-day buffer a freshness risk?
A 17-day buffer of sealed pouches isn't a freshness problem. Our pouches are nitrogen-flushed, heat-sealed aluminum, and the shelf life is 2 years from packing, unopened and stored cool, though matcha is freshest in the first months. Open one pouch at a time, because opened matcha is a different story: my shelf-life guide puts well-stored opened matcha at its best for about one to two months.
A 17-day buffer is far short of a year of stock. In my guide to Hormuz and cafe matcha costs I advise keeping a small buffer for late shipments rather than buying twelve months ahead.
What counts as a failed lot?
A lot is a batch of matcha that shares one lot number. I sort a failed lot three ways: on paperwork, in the cup, or in a lab. Sort the problem first, because the first move is different for each.
| Type | What you see | First move |
|---|---|---|
| Paperwork | The certificate of analysis (COA) has no lot number, or a different one from the bag | Hold the lot unopened and ask for the COA that matches it |
| Cup, stale | Dry powder, but pale or yellowish, a faint or hay-like smell, a flat or slightly bitter taste | Compare it with your sealed reference (a sealed 30 g bag kept from your last good lot), then pause that lot |
| Cup, spoiled | A sour or musty smell, or wet, clumped powder | Stop pouring from that pouch the same minute |
| Lab or safety | A lab result or a recall notice names your lot, or a guest reports feeling unwell | Stop pouring that lot today and call your supplier; if a guest reports feeling unwell, also follow your local food-safety reporting rules |
A COA counts only if its lot or batch number matches the one printed on your bag, which is the paperwork row above and check 1 of my vetting guide. The two cup rows come from my shelf-life guide, where dull, dry matcha is safe but past its best and a sour or musty smell means stop.
Color is a clue, not proof. A 2026 review in Foods ties matcha's bright green primarily to chlorophyll and says oxygen, light and storage conditions add to color loss (Onder et al., 2026), so a duller delivery is worth a side-by-side check against your sealed reference.
What do you do in the first 24 hours of a failed lot?
Run six steps in order, starting the minute you doubt a pouch and finishing with a written note to your supplier by the end of the day.
- Stop and separate. Pull the doubtful pouch off the bar. Don't pour it while you decide.
- Photograph. Shoot the lot code and date on the pouch, then a pinch of powder on white paper beside the last good lot, in the same light.
- Keep everything. Seal the pouch and whatever is left. Don't throw anything away until the claim is settled.
- Write to your supplier today. Give the lot number, the delivery date, the photos, what you saw, how many kilos are left and the date you run out.
- Ask for the remedy in writing. A replacement from a different lot, a credit or a refund, and by when.
- Log it. One line in a notebook: date, lot, what happened, what was promised.
Our published refund policy asks the same of you on arrival: inspect the order and contact us immediately if an item is defective, damaged or the wrong one, and send an image of a damaged or defective item with your refund or replacement request.
For wholesale, what a failed lot gets you depends on the written terms, so ask before you pay, from any supplier. With me it's a simple request: ask in your quote request how a failed lot would be handled, and I'll reply to you myself.
One habit makes every complaint easier. Keep a sealed 30 g bag from each delivery, labeled with the lot and date, until that lot is gone. It's the same idea as the sealed reference in my matcha sample bench test, and it turns "it tastes different" into a side-by-side you can show your supplier.
What do you do when a shipment slips?
When a shipment slips, count your days of cover today, tell your supplier that number, and then choose a bridge in this order: faster shipping, a split order, a second source, a smaller menu. The number comes first because it decides how many of those you still have.
| Days of cover left | What it means | First move |
|---|---|---|
| Over 17 | On plan | Reorder when you fall to 17 |
| 10 to 17 | Inside your reorder point; a delivery on schedule still lands in time | Order today and give your supplier your days-of-cover number |
| 3 to under 10 | A standard delivery, about 8 to 10 days, can land after you run out | Ask for the fastest shipping option, ask about a partial shipment first, and open the backup account |
| Under 3 | Run-out is close | Start the menu fallback and put up the guest sign |
Our shipping policy lists Expedited Shipping at 2 to 3 days next to Standard at 3 to 5, so ask what the faster option costs before you need it. It also says plainly that we aren't responsible for shipments affected by customs, force majeure events, carrier handoffs, or transport strikes or delays. I'd assume every carrier date is an estimate, whoever your supplier is.
Who handles customs when matcha ships from Japan?
Whoever is the importer of record handles customs. On One with Tea's made-to-order and private label runs, we ship and you are the importer of record (bulk supplier terms), so ask any supplier who holds that role before a Japan-origin run ships.
CBP's Form 7501 instructions (February 2026) define the importer of record as the owner or purchaser of the goods, or a licensed customs broker designated by the owner, purchaser or consignee. They also make that party liable for payment of all duties and for meeting all statutory and regulatory requirements incurred as a result of importation (CBP Form 7501 instructions).
Food can also stop at the port for paperwork. FDA's prior notice guidance says food imported or offered for import with inadequate prior notice is subject to refusal and, if refused, must be held at the port of entry unless directed to another location (FDA, Prior Notice guidance).
That guidance is older, so before a Japan-origin run ships, ask your customs broker who files the prior notice and what the plan is if the box is held. In-stock bulk from US inventory has no international leg, so none of this applies to it.
How do you stretch matcha through a gap?
Pause sizes and add-ons first, and keep the dose in every drink you still sell. I won't thin the powder to stretch the tin, because a weak drink loses the regular who orders it for the taste. That is my view as the person who sells the matcha, so weigh it against your own bar.
Here is what the first pause is worth in the made-up cafe. Say it has 1,500 g left when the delay hits. Moving its 10 large iced drinks from 6 g to a standard 3 g saves 30 g a day, so usage drops from 180 g to 150 g, and cover goes from 8.3 days to 10, a gain of 1.7 days.
That is real but small: a pause buys you time to wait for a box, not a way out of a long gap, and for a long gap you need the second source.
Pausing the add-a-shot, a 3 g extra on our house shot menu, saves another 3 g for every guest who would have taken one. And tell guests. A small sign that says matcha is on a limited menu until your next delivery is a better answer than a quiet substitution.
Who approves a substitute lot, and how?
You do, in writing, before it ships. A substitute is a different lot, sometimes a different grade, and "it's the same product" is a claim you can test.
Expect substitutions upstream too. Japan's tea export status report, compiled by the Japan Tea Export Promotion Council, noted for June 2025 that short supply and rising prices had affected product-making for that year's new-tea reservations. Some reserved orders went unfilled and, in some cases, a substitute was proposed in place of the regular product (as summarized in a December 2025 House of Councillors research office paper, in Japanese).
That row covers new-season tea in general, not only matcha. The base behind it is thin: tencha, the raw material of matcha, reached 5,336 tonnes in 2024, about 2.7 times its level ten years earlier, yet it is still only about 7.3 percent of Japan's tea production (same paper).
Write these into your plan:
- A substitute must be named by lot number, with the matching COA, before it ships.
- You get a 30 g sample of it first, and you run it against your sealed reference as in the bench test.
- A different lot can need a different dose, so re-weigh and taste at the bar before you change the recipe card.
- You can decline it without penalty, and the order stays open for the lot you chose.
Before you sign a quote, ask who approves a substitute if your lot sells out or fails testing, because a quote's validity date means little until you know who actually holds the lot. I put that question in check 10 of my vetting guide.
How do you set up a second supplier before you need one?
Qualify the backup in a calm week, with the same checks as your primary, so that you already trust it on a bad day. My playbook suggests running about 80 percent of volume through your primary and keeping a secondary supplier active with orders every 60 to 90 days. The secondary only works if it knows you and you know its matcha.
- Run the ten vetting checks on the backup, not just on your primary.
- Taste its sample blind against your current matcha, using the bench test.
- Write a backup recipe card: the dose that tastes right with its matcha, and the cost per drink from your margin worksheet.
- Place an order on a schedule, so the account is open and someone there knows your name.
If I'm the backup, our samples are free, one set per business, in every grade, as 30 g mylar bags. Ask for them when you request a quote, and the written quote follows within 2 business days.
What should the one-page plan say?
The one-page plan fits on a single sheet by the scale: numbers, names and the six steps. Fill in the blanks while nothing is wrong.
- Numbers. Grams a day. Days of lead time. Your reorder point in grams. The date of your last count.
- Names. Primary supplier contact, backup supplier contact, customs broker if you import, and who on your team places the order.
- Failed-lot routine. The six steps above, with the email address to write to.
- Substitute rule. Lot number, COA and sample first, your written approval.
- Menu fallback. What you pause first, second and third, and who puts up the sign.
- Review date. Re-count your daily grams after any menu change, and re-test the backup twice a year.
Our order calculator turns drinks per day and grams per drink into kilos per month, a good cross-check on your daily grams.
What does One with Tea publish about lead times, shipping and lab testing?
One with Tea publishes these terms today, so you can hold me to them. Our Latte Grade (Organic) and Ceremonial (Organic) are USDA Organic, held in US inventory and ship in 2 to 3 business days; Superior and Royal come on request and are not organic certified. In-stock bulk orders are paid in full before shipping. A made-to-order run takes 4 to 6 weeks from deposit to shipment-ready, with transit quoted on top.
Your written quote follows the price sheet within 2 business days and holds for 21 days.
We test for heavy metals, pesticides, microbes and radiation, and lab results are available on request (see our lab results page), so ask for the one that matches the lot number on your bag. I've walked tea gardens in Shizuoka and Kagoshima, among other regions, and your order has one point of contact from order to delivery. I read every quote request and reply to each one myself.
Whoever you buy from, fill in your matcha supplier backup plan while nothing is wrong. Request a quote and samples when you're ready, or write to info@onewithtea.com with questions first.

Frequently Asked Questions
How much matcha should a cafe keep in reserve?
Keep your lead-time demand plus a week of slack. In my made-up cafe that is 10 days plus 7 days at 180 g a day, so 3,060 g, about 3 kg. Count your own grams a day, add your real order-to-door days, and keep the extra pouches sealed.
What should a cafe do with a bad lot of matcha?
Stop pouring from the doubtful pouch, photograph the lot code and the powder beside your last good lot, and keep everything sealed. Write to your supplier the same day with the lot number, the photos and the date you run out, and ask for the remedy in writing. A sour or musty smell, or wet, clumped powder, means the pouch stays off the bar.
Can a cafe switch matcha grades if its supplier runs out?
Yes, but approve the swap before it ships, not after. A substitute is a different lot and sometimes a different grade, so get it named by lot number with its certificate of analysis, taste a 30 g sample against your sealed reference, and check the dose at the bar. Keep the right to decline it.
Should a cafe have two matcha suppliers?
In my view, yes. One supplier is a single point of failure for your matcha menu. I suggest about 80 percent of volume through the primary and an order to the secondary every 60 to 90 days, with the backup vetted and tasted in advance.
