Archaeologist Laura Dietrich analyzed more than 8,000 grinding tools from Göbekli Tepe, along with hundreds of stone vessels, including vessels large enough to produce 43 gallons of beer or porridge.

Confirmed by original archaeology.org feature and corroborated by Dietrich's peer-reviewed PLOS ONE study and DAI excavation blog; minor variation in tool counts reflects evolving research rather than inconsistency. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
