Advisory

How long should I let these beans rest before brewing them?

ALS-COFFEE-1.2-REST-001

This question is worth asking but is not reducible to a check a page can settle. It is published as guidance, not as a test.

Assertion

rest_window is_stated true

Applicability

applies when
the product is whole-bean roasted coffee
signal
product text discusses degassing or resting

Accepted evidence

  • product_description — a rest or peak window with explicit units and an explicit anchor to the roast date, attributed as this roaster's own recommendation

Explicitly insufficient evidence

What does not count, and why. Published because the omission is where a check quietly becomes a claim.

  • a rest figure attributed to a trade organisation's published standards
    The only trade-anchored rest figure that exists is a cupping sample-preparation requirement for assessment within a day of roasting, and transplanting it to a shopper's brewing advice inverts its meaning. This is the near-miss most likely to be dressed in authority.
  • a rest window with no roast date to anchor it
    A window measured from an unstated roast day is unactionable, and it is the commonest shape.
  • "let rest a few days" or "allow to degas"
    No units, so nothing can be acted on or checked.
  • any single number presented as the industry standard
    Published sources span three to thirty days and disagree openly, and the best-designed study located contradicts the professional norm it tested.
  • a rest claim inferred from the presence of a valve
    A valve manages gas escape and bounds nothing about the coffee's age or readiness.

Conflict rules

  • When a rest window and a peak window are both stated — then record both with their units; the standard reports the seller's stated guidance and declines to adjudicate the number

Discrimination

Authored expectation: no prediction, confidence low. The numeric band this standard used to carry is not published at this grammar version.

Few pages state a window with units and an anchor, and no external definition exists to check the number against, so this is published as advisory rather than as something to run. Degassing is a real measurable physical process; the consumer window is not a settled quantity.

The numeric fail-rate band this reasoning was authored with is NOT carried at grammar 1.2 and is not reproduced here. Authored bands held 1 of 10 against this category's own sample and every miss was HIGH, so a direction derived from the band would inherit the error that condemned it (SCHEMA.md §9.3 step 3). The band survives in ALS-COFFEE v1.1 (standard_hash f8ec2780f60c38931913e5b6cd37506500c8462709209de7180ba6691d6137e7), which is byte-frozen and still served.

For a shopper

Freshly roasted beans release gas for days and can taste better after a rest, but the trade genuinely disagrees about how long, with published advice spanning three to thirty days. Any single number offered as the industry standard is overstating a real disagreement.

For a merchant

State your own recommended window with units, anchored to the roast date, and present it as your recommendation rather than as a settled figure.
