Read the timeline in order
A product description might mention a harvest year while the packet carries a best-before date. Those dates need not contradict each other: they describe different stages. Before comparing two products, write down what each date actually labels. Do not silently convert a harvest year into a milling date or a packing date into a guarantee about storage before purchase.
| Date or claim | What to ask | Avoid assuming |
|---|---|---|
| Harvest | When were these leaves picked, and is the product a blend? | That they were ground immediately |
| Milling | When did these leaves become powder? | That every earlier storage detail is known |
| Packing | When was this package filled or sealed? | That packing and milling happened together |
| Best-before | What date and storage instructions does this product carry? | A new opening date invented from a generic article |
| Opened at home | When did I open this particular pack? | That every product shares one opened-pack window |
First harvest and new harvest are not interchangeable promises
When a seller uses first-harvest language, ask which picking and year it refers to. When it uses new-harvest language, ask what is new about that release. Neither phrase on its own tells you the milling date, the full storage history or how much of the tea you will use before opening another pack.
Ippodo's July 2025 harvest explanation describes resting tencha and introducing new leaves into regular blends over time. Its July 2026 announcement describes a separate seasonal new-harvest matcha release. Together, these examples show that one producer can offer different release approaches. They are not a universal calendar for all Japanese farms or a statement that either product is currently in stock.
Use two imaginary listings to spot the missing information
Listing A says spring harvest and gives a year, but no milling information. Listing B names a regular house blend and provides storage directions and a best-before date. A is more specific about one stage; B may be clearer about how to handle the purchased package. You cannot declare a freshness winner from those incomplete descriptions alone. Ask for the missing detail that matters to your decision.
- Copy the exact date labels from the listing or package, including any year.
- Check whether the tea is a single harvest or a blend; mark undisclosed details unknown.
- Ask about milling or packing only if that information will change your purchase decision.
- Choose a pack size that fits your real drinking frequency and the product's instructions.
- After opening, record the date and follow the maker's storage guidance rather than treating this timeline as a shelf-life calculator.
Calculate how quickly you will use the pack → Portion planning tells you supply duration, not a validated freshness window.
What this timeline cannot establish
Dates do not reconstruct temperature exposure, seal integrity or every other handling condition. This page cannot judge the safety of a particular opened pack or give an expiry extension. Keep its original instructions and contact the seller if a date, seal or product condition looks wrong.
Frequently asked questions
Is first-harvest matcha always freshly milled?
The harvest claim does not establish that. Look for a separate milling statement or ask the maker what information is available.
Is a blend from different harvests automatically stale?
No. Ippodo describes intentionally incorporating different harvests into regular blends. Evaluate the actual product information and storage instructions instead of using the word blend as a freshness verdict.
Which date should I record after buying?
Keep the package's dates and lot information, then add your purchase and opening dates. Label them separately so you do not confuse your own record with a producer claim.
