Overview
Kuhn Rikon's Vase Grinder Mini uses a ceramic grinding stone and a click-adjustable coarseness dial in a compact, screw-cap-refill body sized for counter-to-table use. It's built for salt, pepper, and dried herbs or spices.
Owners who've kept the larger original Vase grinder for decades back the ceramic mechanism's grind quality, but this smaller model has a well-documented failure point across multiple reviews: the plastic housing around the grinding axle cracking after roughly a year and a half to two and a half years of regular use. Grind quality holds up, long-term durability is the trade-off.
- Ceramic grinding stone mechanism
- Click-adjustable coarse-to-fine grind
- Screw-on fill cap
- Compact counter-to-table size
Who it's for
Suits cooks who want a precise, repeatable grind adjustment for salt, pepper or dried herbs and don't mind an unconventional shape. Not the pick for anyone expecting one grinder to last indefinitely without a known wear point.
What buyers say
From Amazon customer reviews.
Owners consistently rate the grind itself highly, describing the fineness adjustment as satisfying and repeatable and the ceramic mechanism as capable of handling tough spices others struggle with. The recurring complaint across several reviews is that the plastic housing supporting the grinding axle cracks after extended use, timelines range from as little as 3 months in isolated cases to roughly 2.5 years for most owners, after which the mill stops grinding.
Strengths and trade-offs
Drawn from this product's published specifications.
- Ceramic mechanism grinds tough spices consistently
- Click-adjustable coarseness holds its setting
- Simple screw-on cap for refilling
Performance notes
A ceramic grinding stone rather than steel handles the actual grinding, and the coarseness dial clicks into position so a setting can be dialed back to reliably. The screw-on cap makes refilling straightforward without disassembling the body, and the mechanism keeps working through dense material like peppercorns without binding.
