“show me a map of all specialty coffee roaster across the USA. show me their founding date and other important attributes as well in a table. do state-by-state queries, and then aggregate”
State-by-state web queries run on 2026-08-31 produced a best-effort discovery index — not an official registry — of 3,300 deduplicated specialty, craft and third-wave roaster names across 49 states plus Washington, DC, backed by 6,177 source mentions. West Virginia was queried but no entry survived the evidence filters. The map shows discovered counts per state, not storefront locations: city is known for only 541 of the 3,300 names.
Hover a state for its count and attribute coverage. Colour is discovered roaster count; darker roast, more roasters. Counts are discovery hits, not a census.
Method: best-effort live-web discovery index built from state-by-state queries on 2026-08-31, then deduplicated and aggregated — 3,300 state-roaster rows, 50 covered jurisdictions (49 states + DC; West Virginia returned no entry that passed evidence and state-matching filters), 6,177 source mentions. “Specialty roaster” has no complete national licensing list; sources may be stale, operating status can change, and duplicate or brand-location ambiguity may remain. Blank cells mean unresolved or not stated, never “No”. Long free-text notes are truncated for space; no coordinates or founding dates were inferred.
