Resting between roasts (tui huo)
Weeks or months of doing nothing between one roast and the next, during which the raw fire note recedes and the maker finds out what the roast actually did.
The categories this step defines
In tea, processing is not a modifier applied to a category — it is what creates the category. These are the types that exist because this step exists.
- Oolong — Deliberate bruising to initiate edge oxidation, halted partway, frequently followed by roasting.
What it is
A tea straight off the charcoal tastes of charcoal. The roast note sits on top of everything, the leaf is dry and hard, and no useful judgement can be made about whether it has had enough. So a roasted oolong is sealed and set aside — a few weeks at minimum, often two or three months — and during that period the surface fire note recedes and the sweetness the roast built underneath comes forward. Only then is the tea tasted again and only then is the decision taken about whether to roast it a second or third time. This makes a heavily roasted Wuyi oolong a tea with a production schedule measured in seasons rather than days, and it explains something buyers find confusing: a yancha bought too soon after its final roast is not the tea the producer intended to sell, and the same tea a few months later is noticeably different without anybody having done anything to it. It is also the reason a producer's roasting decisions are made against last year's experience rather than this week's.
Also transliterated as: tui huo, tuihuo, hui huo.
What it does to the leaf
Holds roasted leaf sealed and undisturbed so that the volatile surface products of the roast dissipate and moisture equalises through the leaf, making the underlying effect of the roast assessable.
What it does to the cup
The harsh, dry, smoky top note of a fresh roast fades and a rounder caramelised sweetness comes forward; a tea judged before its rest is routinely judged to be over-roasted when it is not.
Variants that matter
Ways this step is carried out that produce genuinely different results, rather than regional names for the same thing.
- Rest between staged roasts
- Two or three roasts separated by rests of weeks or months. The standard construction for heavily roasted Wuyi and Anxi styles.
- Rest before sale
- A final rest after the last roast, before the tea is released. Producers who skip it sell a tea that will improve in the buyer's cupboard, which the buyer then credits to storage.
- Annual re-roasting
- Stored roasted oolong is given a light refresh roast in later years, each time followed by its own rest. `process-re-firing` covers the operation; this record covers the interval after it.
Where this gets misdescribed
Roast level is discussed as though it were set at the fire and fixed thereafter. It is set at the fire and then read weeks later, and a great deal of what drinkers describe as heavy roasting is a light roast tasted too early.
Other steps at the Roasting stage
- Charcoal roasting — Slow roasting over charcoal in baskets, in repeated sessions separated by weeks of resting.
- Electric baking — Roasting in a temperature-controlled electric oven rather than over charcoal.
- Final firing (hiire) — The last heat a Japanese green tea receives, applied at the refiner rather than the grower, and the lever that decides whether a sencha reads as fresh and grassy or sweet and toasted.
- Hojicha roasting — A short, hot roast applied to finished Japanese green tea, which converts it into a categorically different drink in minutes.
- Re-firing — A light low-temperature bake applied to already-finished tea to drive off absorbed moisture.
- Roasting — Applying sustained heat to finished leaf to build toasted character, reduce moisture and stabilise the tea for keeping.
Teas that go through this step
Guides covering this step
- What happens when the order is wrong — Almost every fault in tea is a timing fault rather than a technique fault. Here is what each of the common mis-orderings actually produces, and why several of them are invisible on the day and obvious six months later.
- The steps between the steps — Spreading, cooling, resting, turning. Four operations that occupy most of the elapsed time in tea manufacture, have names in every producing language, and are compressed in English writing into the word “then”.
- What happens after the drier — In several traditions a tea is not finished when it comes out of the drying machine. Sorting, refining, final firing, blending and resting are real operations, they are frequently performed by a different business, and they can move a tea further than anything the grower did.
