The smart tap which aims to serve 'perfect' beer

San Francisco start-up, Pubinno, has created smart taps that aim to pour a great beer every time.

The device is designed to work with bartenders, not replace them and connects to a dashboard that collects data about the pints served.

Each tap costs $35 (£27) a month. They are currently in 30 bars and breweries in the US and Europe.
