About Grindhog

Never spend 4-5 shots dialing in a new bag again. Grindhog uses knowledge graphs to learn from your equipment and beans, instantly recommending the perfect grind settings - and it taps into the power of the dial-in community!

What’s new

Version 0.3.16 · Updated July 23, 2026

This release improves Grindhog’s recommendation engine: - Recommendations now recognize when a previously successful recipe may no longer perform as expected as beans age. - Grindhog considers recent extraction time and rating changes when calculating recommendation confidence. - Recommendation matching is more cautious when newer shots indicate that an older recipe may need adjustment.
