Observed evidence / no theater
Testing standard
What Espresso Receipt has and has not physically tested, and the protocol required before we publish observed performance claims.
Current status
At launch, Espresso Receipt has not physically tested every catalog product. Current recommendation receipts are built from verified public specifications, authorized-retailer records, disclosed cost assumptions, and a versioned matching model. A product page must say “specification-verified” unless an observed test record exists.
We will not convert a manufacturer claim, owner anecdote, review roundup, or modeled score into an “our tests show” statement.
Minimum hands-on protocol
Before a page receives an Observed label, its test record should include:
- Retail U.S. production unit, firmware if applicable, purchase or loan status, and test dates.
- Room conditions, water composition, coffee, dose, basket, grinder, and warm-up definition.
- At least three repeated timing or measurement runs, with raw values retained.
- Stored and operating dimensions, including portafilter, reservoir, hopper, cord, and steam-wand travel.
- Ready time, hands-on time, one-drink time, two-drink time, and cleanup time reported separately.
- Sound measurements with device, distance, room background, and operating task documented.
- Energy readings with meter and cycle boundaries documented when energy is claimed.
- Photographs or video sufficient to identify the exact unit and reproduce the workflow.
What each test label means
- Specification-verified
- Public primary or authorized-retailer sources checked; no hands-on performance claim implied.
- Observed
- A named unit was used under a published protocol, with test date and limitations attached.
- Measured
- A numeric observation has instrument, procedure, units, and repeated-run details.
- Long-term
- The exact unit has a published ownership interval and maintenance log; short reviews do not qualify.
Samples and commercial relationships
If a manufacturer supplies or discounts a unit, that fact belongs near the result. Brands may correct objective product facts before publication, but they do not receive score approval, copy approval, or a promise of coverage. Affiliate availability cannot convert a product into a test winner. Read the editorial policy and affiliate disclosure.
