During the Venice Biennale Architecture 2025, coffee made from Venice's canals is served at the Canal Café by design studio Diller Scofidio + Renfro.
The water used for the coffee is drawn directly from the city's canals and goes through a purification system designed to make it potable, ensuring the safety of drinking it.
The water purification process involves an artificial wetland, reverse osmosis, and UV light treatment to clean the water naturally and remove toxins before turning it into espresso.
The Canal Café has a monitoring system in place to track the purification process, making sure that the coffee made from the canals remains potable for visitors at the Venice Biennale Architecture 2025.
