Grinders for spices? It’s a tempting shortcut—but the risks might outweigh the rewards. The Reddit thread buzzes with debate: is it safe to repurpose your coffee grinder for spices, or is it a recipe for disaster? The consensus leans toward caution, but the question lingers: what if you’re already grinding your own beans and want to experiment?
The science is clear: coffee grinders aren’t designed for spices. Metal components and retention chambers—key features in burr grinders—trap oils and residues from spices like cinnamon or clove. These oils can seep into your coffee grounds, altering flavor profiles and potentially leaving a lingering spice note in your brew. Even if you clean the grinder thoroughly, the risk of cross-contamination remains. A single misstep, like grinding nutmeg alongside coffee, could ruin a batch of beans and leave your grinder smelling like a spice rack.
Then there’s the practicality. Coffee grinders prioritize consistency and precision, while spices demand a coarser grind and less control. The DF64 and Kin K4, though made of metal, aren’t built for the varied textures of spices. Their retention chambers, designed to hold coffee particles, struggle with larger spice fragments. Over time, this can lead to uneven grinding and clogs. Plus, if you’re using the same grinder for both coffee and spices, you’re essentially creating a hybrid tool that’s neither fully one nor the other.
The real issue isn’t just about flavor—it’s about respect for your equipment. A grinder is an investment, and repurposing it for spices risks shortening its lifespan. If you’re set on experimenting, consider a dedicated spice grinder or a mortar and pestle. But if you’re tempted to test the waters, start small: grind a single spice and monitor the results.
Key points: Cross-contamination risks taint both coffee and spices; grinders aren’t built for the varied textures of spices; repurposing shortens tool lifespan.
