Voltaire is the world’s first high-performance portable burr grinder. An IoT (internet of things) connected sensing platform and smartphone app allow users to measure bean freshness and receive replenishment alerts or auto-replenish when it’s time for fresh beans. Voltaire’s high-performance LiFePO4 batteries will last through over 3lbs of beans and hold a charge for up to three weeks. This is seriously smart coffee.

If you’re not into the whole internet-of-things movement, but still want an amazing portable grinder, you can opt out of the sensing platform and simply pledge for the standalone model.
