Espresso & Machines Manufacturer documentation, cited
Method

How this site sources every specification

Espresso & Machines documents what espresso manufacturers publish. Every specification is taken from a manufacturer instruction book, service manual, declaration of conformity, or product leaflet, cited by document name, revision and URL, and dated to the day it was read. Nothing here is a test result, a measurement, or a personal impression. Where a manufacturer publishes nothing on a question, the page says so instead of estimating.

Every specification names its document

A specification on this site carries the document it came from: the manufacturer, the document type, its revision or issue code where the document prints one, and the URL it was downloaded from. Where a document exists in several regional versions that disagree, the page states which version was read and what the other version says instead.

Every page is dated

Manufacturer documents get revised and manufacturer URLs get retired. Each page states the date its documents were read, so a reader can tell how old the reading is before relying on it.

Counts state how they were counted

Where a page reports a number of models, documents or brands, it states the rule that produced the number and the set it was counted from. A count without its counting rule is not published here.

What this site does not do

  • No machine on this site has been tested, measured, timed or disassembled by its author.
  • No page reports a shot time, a brew temperature, a pressure reading or a taste result.
  • No page states that a part from one machine fits another unless both machines share a part number in a published parts catalogue. Where they do not, the page says that no published source addresses it.
  • No page ranks machines or names a best one. That judgment needs testing this site does not do.

Where the documents stop

The most useful pages here are often the ones recording an absence. When five manufacturers are checked for the same figure and none of them publishes it, that is a finding, and it is published as one rather than filled in with an estimate.
