R10,000 | Secondhand | Excellent condition
The short version
Sigma is a modern commercial-grinder brand that pairs Italian-made burrs with Korean-engineered electronics — a combination that’s earned it a strong following in busy South African cafés wanting professional grinding without a top-tier European price tag. This is Sigma’s on-demand model with the smart temperature-and-humidity display, finished in silver/grey, in excellent condition and ready to drop straight into a café setup or a serious home espresso bar. Confirmed from the photos: this is the on-demand touchpad version with the live environmental readout on the front LCD.
New to on-demand commercial grinders? Here’s the rundown
“On-demand” means fresh, every time. Instead of grinding a batch in advance and storing it in a chamber where it goes stale by the minute, an on-demand grinder grinds precisely what you need, exactly when you need it, straight into the portafilter. Since ground coffee starts losing aroma and flavour within minutes, on-demand grinding is the modern standard for quality espresso.
The smart display is the standout feature. The front LCD shows live bean temperature and humidity — information that normally only lives on far more expensive grinders. Why does it matter? Coffee grinds slightly differently as conditions change through the day: warmer burrs and more humid air shift how the beans break down, which subtly changes your shot. Seeing those readings lets a barista stay ahead of the drift and keep espresso dialled in, rather than chasing it.
Commercial vs. home grinders. As with all the professional gear in this range, the gap from a home grinder comes down to burr quality and duty cycle. This Sigma uses Italian flat burrs and a motor built to grind continuously through a service without overheating or losing consistency — where a domestic grinder would struggle and heat up. For a home espresso setup, that means enormous headroom: you’ll never come close to working it hard, and you get commercial-grade consistency in every dose.
Barista-friendly touches: a touch-panel control layout with programmable single/double dose buttons and a manual mode, a hands-free portafilter cradle so you can grind straight into the basket, and an anti-static, anti-clumping grind path for clean, even dosing.
