Hario Skerton Pro Upgrade Kit

The Blue Horse Upgrade Kit, compatible solely with the Hario Skerton PRO coffee grinder, produces a better and more consistent grind by centering and stabilizing the lower burr. This installation requires only a screwdriver, and there is no need to remove the lower burr from its shaft. While the grinder alone is suitable for finer grinds, the upgrade kit is a must-have for users of french press or those demanding a consistent coarse grind. It significantly improves the consistency of coarser grinds by keeping the burr centered, resulting in an even gap between the upper and lower burrs - the key to a reliable and consistent grind.

The easy installation process takes approximately 5 minutes and is as follows: First, install the burr shaft and upgrade kit as shown. Next, reinstall the upper burr and retaining ring. Finally, install the lower burr and set the grind adjuster knob. This reduced burr wobble means better coffee, as the stabilized burr shaft maintains a more consistent gap between the burrs, resulting in more uniform grinds. Fewer fines in the ground coffee translates to a smoother, less bitter final brew.

Designed and manufactured in the USA, this PRO Upgrade Kit is compatible solely with the Hario Skerton PRO, not the original Hario Skerton model. It stabilizes the lower burr to produce a more consistent coarse grind, making it perfect for french press users. The easy 5-minute installation with a single screwdriver sets this kit apart from the original Hario Skerton upgrade, which has a 4.2-star rating from 320 customers, while the PRO version boasts a 4.1-star rating from 21 reviews and is priced at $12.99.
