the standard
the company (not the coffee) is certified to balance profit with social and environmental impact. b lab scores the business across governance, workers, community, environment, and customers. 80/200 minimum to certify.
audit cycle
every three years. annual disclosure of impact metrics. legally requires the business to amend articles of incorporation to consider stakeholders, not just shareholders.
cost to the roaster
$1k-$50k/year in certification fees by revenue band. the cert signals values to wholesale buyers - cafés running b-corp programmes preference b-corp roasters.
a roaster carrying b corpon the bag doesn't always mean every bean is certified. ask for the cert number and the percentage of their range that qualifies. transparency reports are the gold standard.
certification proves a minimum standard. it doesn't tell you about cup quality, freshness, or how the roaster treats their wholesale clients. use this directory to shortlist, then judge the coffee on the cup.
many specialty roasters carry two or three stacked certs (organic + fair trade, b-corp + direct trade). that signals values-led sourcing. it also adds cost - a single-cert bean is typically 10-20% cheaper than the same lot triple-stacked.
