Topic: Cork Oak

A recent trip to the Algarve region of Portugal reveals striking similarities between the Portuguese landscape and California. The discussion details the biology of cork oak trees, noting that they are a specific species of oak and that every tree in Portugal is legally registered. The hosts suggest that California could potentially support a lucrative cork industry based on these environmental parallels.

The Portuguese cork industry is facing a public relations battle against the plastics industry regarding the sustainability of cork stoppers. Cork is harvested from the bark of specific oak trees every seven years, a process that does not harm the tree and is strictly regulated by Portuguese law. Despite propaganda claiming cork forests are shrinking, the plantations are currently growing at a rate of four percent annually.
