GDS stands for Grinding Dynamics Research. Past grinding for various brew strategies, the variable-RPM machine is designed as a platform for evaluating the identical espresso floor via completely different burr geometries, speeds and workflows.
The machine is at present priced at US$3,450 for preorders immediately via Choice-O.
The system might be configured with a customized set of 100-millimeter conical burrs on one aspect and 102-millimeter flat burrs on the opposite, or with twin flat-burr carriers that enable customers to isolate RPM as a variable or examine completely different flat-burr geometries via side-by-side brewing.
“It’s not likely about combining two grinders into one,” Choice-O Managing Director Sam Regulation informed Each day Espresso Information. “It’s about giving customers the liberty to decide on the burr set that most closely fits the espresso, brewing technique or cup profile they need at that second.”

We additionally assume some cafes could think about it as a press release piece.”
A single 1,650-watt brushless DC motor drives a tuned belt-drive system that delivers completely different RPM ranges on all sides. The system affords ranges of 100 to 500 RPM on the conical aspect and 200 to 2,000 RPM on the flat aspect.
As a result of the grinder is designed for compatibility with normal North American 15-amp family retailers, Choice-O recommends grinding on just one burr set at a time, at the same time as each units spin directly.

The next yr, Choice-O merged with Australian firm Helor, maker of high-end guide espresso grinders, and launched the primary Choice-O electrical grinder, the Lagom P64. The corporate has since rolled out a variety of high-end house and prosumer grinders of various sizes, with flat and conical burr choices and the identical clear, trendy industrial design language.
The Lagom GDS comes amid rising curiosity in particular person grinders that may alternate between flat and conical burr units.
In 2021, Hong Kong-based Wug2 launched its mannequin 83A grinder, providing variable velocity and interchangeable burr carriers appropriate with flat and conical burrs. Three years later, one other Hong Kong-based firm, Varia, launched its VS6 grinder with an ordinary set of 58-millimeter flat burrs and an choice for 63-millimeter conical burrs. Coming quickly from China is the Muvna Mammoth grinder, a machine initially revealed late final yr with removable, swappable grind chambers containing both 98-millimeter flat burrs or 83-millimeter conical burrs.
