Best Coffee Grinders for Espresso (2025 Guide)
Ask any experienced barista what matters most for great espresso, and they'll say the grinder. A quality grinder transforms the same beans from a mediocre shot into something extraordinary. It's not an exaggeration to say that a $300 grinder paired with a $300 machine will produce better espresso than a $100 grinder paired with a $2,000 machine.
Espresso demands a grinder that can produce a consistent, fine grind with minimal clumping and low retention. The two main burr types — flat and conical — produce different flavor profiles: flat burrs tend toward clarity and uniformity, while conical burrs often produce more body and sweetness. Both can make outstanding espresso.
Key features to consider include burr size (larger burrs grind faster and cooler), stepless adjustment (for infinite grind fine-tuning), single-dose capability (for minimal retention), and build quality. Here are our top picks across every price range.
