Sigma On Demand Coffee Grinder

About the Brand

Sigma is a South Korean grinder brand based in Sejong, built around what it calls Barista Friendly Design — electrical and electronic components made in Korea, paired with burrs developed over years of collaboration with Italian craftsmen. The brand's grinders are shaped by direct feedback from working baristas, aimed at fast, low-noise, genuinely easy-to-use commercial grinding. Sigma's footprint outside Korea is still growing, so we've kept the details here to what's verifiable.

The Product

The Sigma On Demand Coffee Grinder is built around a 64mm burr set refined through years of development with Italian burr specialists, aimed at fast, low-heat, low-noise grinding for a busy bar. Preset single, double and manual dosing keep daily service simple, while a digital display tracks temperature and humidity in real time. This is barista-designed grinding, built for speed without the noise.

Key Features

64mm Burrs (Fast, Refined Grinding)

Developed through years of collaboration with Italian burr craftsmen, this burr set is tuned for faster grinding with reduced heat and noise.

Grind-On-Demand Dosing (Single, Double or Manual)

Preset single and double doses, or switch to manual control, covering both quick service and custom portioning.

Temperature & Humidity Digital Display (Real-Time Awareness)

Monitor grinding conditions at a glance, giving you one more reference point when dialling in.

Hands-Free Portafilter Holder (Faster, Cleaner Dosing)

A robust holder frees up your hands during dosing, speeding up your workflow behind the bar.

Anti-Static, Anti-Clump Outlet (Cleaner Grounds Delivery)

Reduces static cling and clumping at the outlet, so grounds land in the portafilter rather than on your counter.

1.6kg Hopper (Fewer Refills During Service)

A 1.6kg hopper keeps you grinding through a busy shift without constant refilling.

LCD Display (Clear Daily Operation)

Simple, legible controls for adjusting dose and settings without digging through menus.

Who It's Built For

You want fast, quiet grinding from a machine designed by baristas rather than just engineers, without importing an unfamiliar brand at a premium. The Sigma On Demand gives you 64mm burrs, real-time environmental feedback and hands-free dosing in a grinder built for daily bar use. Built by baristas, priced for reality — that's Sigma's pitch.
