Origin and traceability terms explained

How country, region, producer, farm, lot, species, variety, process and roast relate to each other — and why none of them alone predicts flavour.

Geography: country, region, producer, farm and lot

These describe increasingly specific places and people, not increasingly important facts. A country (e.g. Ethiopia) covers enormously varied growing conditions within it; a growing region narrows this to a named area within it; a producer or farm is a specific business or smallholding within that region; a lot is a quantity of coffee kept and sold as one thing, which may be one farm's separately processed batch or a blend of many sources. The trade calls small, separately sold parcels micro-lots, a word with no standard definition. A claim made at the country level (like 'grown in Ethiopia') says very little about a specific cup compared with a claim made at the lot level, and the two should not be treated as equally precise.

Biology: species and variety

Species and variety are a separate axis entirely from geography. Species (mainly Coffea arabica or Coffea robusta/canephora in commercial coffee) is the broadest botanical grouping; variety (sometimes called cultivar) is a specific genetic type within a species. The variety catalogue CoffeeHQ uses records each one's yield, disease resistance and quality potential separately — for example SL28 and SL34, both selected in Kenya in the 1930s. A catalogue rating describes what a plant can do under good conditions, so a variety's name does not fix how a particular coffee tastes.

Process and roast: what happens after harvest

Processing method (see processing and roasting) and roast level are decisions made after the coffee is grown, not facts about where or what it is — the same lot could in principle be processed or roasted differently. This is why a full, specific description of a coffee usually needs several of these axes together (e.g. 'a washed SL28 lot from a specific Kenyan farm, light roast') rather than any single term doing all the work.

Why this means broad origin claims deserve caution

Because country, region, producer, species, variety, process and roast are all independent variables, a claim like 'Ethiopian coffee tastes like X' is really a claim about one narrow combination of all of these, generalised past the point it can support. That is CoffeeHQ's reasoning from how the terms are defined, not a finding from a tasting study. CoffeeHQ's own origin pages describe growing and processing facts for this reason, rather than asserting a single fixed flavour for an entire country.
