Best Burr Grinder for Home Coffee? DeLonghi KG39 Review

If you’re trying to make better drip or filter coffee at home but your current grinder only gives you dust or gravel, you’re not alone. Many entry-level grinders lack consistent grind settings, don’t offer enough range, or simply can’t keep up with a full pot. The right grinder should let you adjust easily—without guessing—and handle enough coffee for your daily brew routine.

The DeLonghi KG39 is a straightforward electric burr grinder with three distinct grind settings (marked by green indicator lights), a 4–12 cup capacity selector, and auto shut-off after grinding. It’s built for home users making multiple cups at once, not single-origin pour-overs, but it gets the basics right for drip coffee.

What Is the DeLonghi KG39?

The DeLonghi KG39 is an electric blade-and-burr-style coffee grinder manufactured in China. It features a simple control layout with a grind selection switch showing three green indicator lights for choosing between coarse, medium, and fine grind settings. The machine includes a stainless steel burr set designed for durability, and a grind amount selector that lets you choose between grinding enough coffee for 4 to 12 cups—with automatic power-off once the selected amount is reached. The maximum output is enough to brew approximately 12 cups of coffee. It is operated via an on/off button, has an ergonomic rubberized handle for easy handling, includes a built-in cord storage compartment, and has non-slip rubber feet to keep it stable during use. The device consumes 150W of power.
