Equipment notes

The GS30 is a household electric burr grinder from Australia's Precision Coffee Tools, positioned a step above the mainstream home machines above as an espresso-oriented model. It features micrometric coarseness adjustment and a generous hopper, and is designed to operate via a front button and a rear switch. It uses steel flat burrs, grinding beans between two discs and biasing toward particle uniformity and cup clarity. A comparatively large 60mm-class flat burr combined with micrometric adjustment lets it tighten values finely in the fine zone, more so than mainstream machines at this price. It handles from the espresso-fine zone through drip, with strength across the filter-to-espresso span rather than the very coarse zone of French press. It fits home users on a limited budget aiming at both espresso and precise filter grinding, and those who value fine adjustment resolution. For simply grinding large amounts coarse for filter only, a simpler machine is more reasonable.
