Technological Corks, Zinc Gutters, Traditional Basque Ham, Chisteras

How It's Made – Season 29

Processed cork is purified, ground and compressed into consistent bottle closures designed to reduce natural defects. Zinc sheet is roll-formed and joined into rain gutters; pork legs are trimmed, salted and slowly air-dried into traditional Basque ham; and long, curved chisteras used in pelota are woven by hand around shaped wooden frames.
