Episode Details

When the Ever Given blocked the Suez Canal in 2021, North American boba shops faced a tapioca pearl shortage. This episode uses that strange supply chain story to explore bubble tea, from the precise brewing temperatures for green and black tea to pearls that must be used within 24 hours, cheese foam that balances bitterness, and heat-sealed cups built for shaking.

We examine the rival origin claims of Chun Shui Tang in Taichung and Hanlin Tea Room in Tainan, and the court ruling that declared bubble tea a non-patentable food, which helped it spread worldwide. We also look at boba as a cultural symbol for Asian American youth and the health concerns around sugar, creamers and dense tapioca.
