    Introduction: Ditching the Blade for a Real Grind

    Quick Answer: The DeLonghi KG79 is a budget-friendly electric flat burr grinder. It replaces inconsistent blade choppers to give you an even, precise coffee grind for daily home brewing.

    The Problem with Blade Grinders Making coffee on a cold morning requires the right gear. Using a cheap blade grinder is like cutting a 2×4 board with a butter knife. The fast blade chops the beans poorly. This leaves you with a messy mix of fine dust and large chunks. The final result in your cup? A weak and sour brew.

    Enter the DeLonghi KG79 Meet the DeLonghi KG79. Think of it as a handy power tool for your kitchen. It is an electric flat burr grinder that fits a tight budget. During our test runs, it proved to be a solid starting point for better daily coffee. It handles the hard work without the high cost.

    Why Grinding Fresh Matters Why does a fresh, even grind matter so much? The secret is in the burrs. Burr grinders crush coffee beans to a uniform size. Blade grinders just hack them apart. When the grind size is even, hot water pulls the flavor out smoothly. You avoid that harsh, burnt taste entirely.

    Who Is This Grinder For?

    • The DIY Home Maker: Great for learning the ropes of good coffee extraction.
    • The Beginner: Very easy to use right out of the box.
    • The Budget Buyer: A major taste upgrade without a huge price tag.

    If you want to step up from old, pre-ground coffee, this unit is a smart, low-cost choice.

    Key Features That Actually Work Hard

    Key Feature

    The Flat Burr Grinding System Inside the machine are two flat metal wheels. These are the burrs. They work together to crush the coffee beans. Think of a power sander in a wood workshop. A sander gives a smooth, even finish. The burrs do the same for your coffee. They give you a uniform grind size. This provides a much better extraction than a choppy blade.

    16 Adjustable Grind Settings You can change the grind size easily using the side dial. You get 16 different settings. The range goes from fine to coarse. During our testing, the dial moved smoothly and clicked right into place. This simple setup helps you match the exact grind size to your specific coffee maker.

    Automatic Cup Selector (2-12 Cups) An automatic cup selector sits on the front of the unit. This dial lets you pick how much coffee to grind. You can set it anywhere from two to twelve cups. Just push the start button. The machine stops on its own when finished. This reduces waste and adds speed to your morning routine.

    Removable Upper Burr for Easy Cleaning Coffee oils build up fast on metal parts. Keeping the burrs clean is vital for good taste. The top burr on the KG79 pops right out. You just twist it and lift. This makes deep cleaning very simple. A clean machine lasts much longer. It also makes a DeLonghi coffee grinder burr replacement fast and easy if the metal ever wears down over the years.

    Built-In Dual Safety System This grinder features a strict safety shut-off. The motor will not run if the top bean hopper is loose. It also stops if the ground coffee bin is removed. Think of it like the automatic brake on a table saw. If you pull the bin out while it runs, the motor stops instantly. This keeps your hands safe and prevents big messes.

    Design, Build Quality, and Maintenance

    Materials and Look The KG79 features a black plastic outer body. The design is boxy and very utilitarian. It does not look fancy, but it feels sturdy enough for daily home use. It is built to get the job done.

    Compact Size and Footprint Its size is a major plus for small kitchens. The footprint is very compact. It tucks easily under standard kitchen cabinets. You will not lose much valuable counter space.

    Hopper and Catch Bin The top bean hopper holds 120 grams of whole beans. It is made of clear plastic. The ground coffee container at the bottom is also clear. This makes it very easy to see exactly how much coffee you have ready.

    Maintenance and the Static Solution Maintenance is easy but required. Never use water to wash the metal burrs. Use a small, stiff-bristled brush to clear out old grounds. During testing, we noticed that static buildup caused coffee dust to stick badly to the plastic bin walls. We fixed this quickly using the Ross Droplet Technique (RDT). You just add a tiny drop of water to your whole beans before grinding them. This trick completely eliminates the static. The grounds pour out clean.

    Performance Test: Real-World Use

    Grinding Speed How fast does the DeLonghi KG79 work? During our tests, it pushed out about 1.8 grams of coffee per second. This is a very good speed for a budget home grinder. It takes less than half a minute to grind beans for a full pot of drip coffee.

    The Noise Level We need to be honest about the noise. This machine is loud. When it runs, the motor makes a high-pitched whine. We noticed this right away during our first morning test. It will likely wake up anyone sleeping in the next room.

    Grind Evenness We checked the ground coffee across all 16 settings. The unit does a great job in the middle range. The medium size for drip coffee is very even. The coarse size for a French press is also solid. But it struggles at the far ends. On the very finest setting, we saw some big chunks mixed with fine dust.

    Ease of Use This grinder is entirely idiot-proof. You load the beans in the top. You turn the side dial to your size. Then, you push the front button. It does exactly what you tell it to do.

    Best Brewing Methods for the KG79

    Where It Wins This electric flat burr grinder shines with standard daily brewing. It is a perfect match for these popular coffee styles:

    • Drip Coffee Makers: The medium setting gives a smooth, balanced pot of coffee.
    • French Press: The coarse setting works perfectly for soaking grounds in water.
    • Pour-Over (Chemex or V60): The medium-fine settings allow for steady water flow.
    • Moka Pot: The fine settings are tight enough for a strong stovetop brew.

    Where It Fails The KG79 has limits. It fails at real espresso. Out of the box, it cannot grind beans fine enough for a proper espresso machine. The grind is simply too sloppy at the lowest level. The water will shoot right through the coffee. If you want thick espresso with rich crema, this grinder falls short.

    The Good and The Bad: Pros & Cons

    Quick Answer: The DeLonghi KG79 offers great value and ease of use for daily coffee. However, it is quite loud and cannot grind fine enough for true espresso out of the box.

    The Pros: Where It Excels

    • Highly Affordable: It brings electric flat burr grinding to almost any kitchen budget.
    • Very Beginner-Friendly: Just load the beans, pick a size, and push start.
    • 16 Grind Settings: You get plenty of choices for standard drip and French press brewers.
    • Compact Footprint: It is small and takes up very little counter space.
    • Easy to Clean: The removable top burr makes quick maintenance a breeze.

    The Cons: Where It Falls Short

    • Sloppy Fine Settings: The lowest grind settings create too much dust mixed with large chunks.
    • Loud Motor Noise: The high-pitched sound is very noticeable during early morning use.
    • Static Buildup: Coffee dust sticks to the plastic bin walls heavily. (Though the water droplet trick fixes this fast).
    • Not for Pro Espresso: It fails at making rich espresso without voiding the warranty and modifying the internal parts.

    Comparison: DeLonghi KG79 vs. The Rest

    DeLonghi KG79 vs. DeLonghi KG89 These two units are exactly the same inside. The motor and the metal burrs match perfectly. The only difference is the outer case. The KG89 features a stainless steel look. The KG79 uses a tough black plastic body. If you want to save money, buy the KG79. You get the exact same coffee quality for less cash.

    DeLonghi KG79 vs. Manual Hand Grinders A good manual hand grinder offers better precision for the same price. A hand grinder gives you a much more even grind size. However, hand grinding takes real physical effort. Turning a crank by hand at six in the morning gets old fast. The electric KG79 offers push-button speed and pure convenience.

    DeLonghi KG79 vs. Cheap Blade Grinders This is not even a fair fight. The KG79 wins easily every single time. A blade grinder simply chops beans into a chaotic mess. The flat burr system in the KG79 crushes beans much more evenly. Upgrading from a cheap blade chopper to this burr grinder will completely change how your coffee tastes.

    The Good and The Bad: Pros & Cons

    Quick Answer: The DeLonghi KG79 offers excellent value for standard daily coffee. However, the motor is quite loud, and the unit fails at making fine espresso grinds out of the box.

    Here is a simple breakdown of the best and worst features we found during our hands-on tests.

    The Pros: Where It Wins

    • Highly Affordable: It brings electric flat burr grinding to almost any kitchen budget.
    • Beginner-Friendly: It is very easy to use. Just load your beans, pick a size, and push start.
    • 16 Grind Settings: You get plenty of choices for standard drip and French press brewers.
    • Compact Footprint: It is small. It takes up very little space on your counter.
    • Easy to Clean: The top burr lifts right out for fast wiping and brushing.

    The Cons: Where It Falls Short

    • Sloppy Fine Settings: The lowest grind settings create too much dust mixed with large chunks.
    • Loud Motor Noise: The high-pitched sound is very loud. We noticed this clearly during our first morning test.
    • Static Buildup: Coffee dust sticks heavily to the plastic bin walls. Luckily, the water droplet trick fixes this fast.
    • No Pro Espresso: It is useless for high-end espresso without voiding the warranty and modifying the internal parts.

    Comparison: DeLonghi KG79 vs. The Rest

    DeLonghi KG79 vs. DeLonghi KG89 These two machines are exactly the same inside. They share the same motor and flat burr system. The only difference is the outer shell. The KG89 has a metal look. The KG79 uses black plastic. If you want to save cash, buy the KG79. You get the exact same coffee quality for less money.

    DeLonghi KG79 vs. Manual Hand Grinders A good hand grinder gives you better precision for the same price. It makes a more even grind. However, manual grinding takes physical work. Turning a heavy crank by hand at six in the morning is tough. The electric KG79 gives you fast, push-button ease instead.

    DeLonghi KG79 vs. Cheap Blade Grinders This is not a close race. The KG79 wins easily. A blade grinder just chops beans into an uneven mess. The flat burr system on the KG79 crushes beans evenly. Upgrading from a blade chopper to this burr unit will quickly improve your daily cup.

    Who Should Actually Buy This Grinder?

    The Beginner Are you tired of stale, pre-ground coffee? This unit is the perfect starting point. It is very simple to learn and use daily.

    The Budget Barista You want a real flavor upgrade. But you do not want to spend over two hundred dollars. This electric flat burr grinder fits a tight budget perfectly.

    The Drip Coffee Drinker This is a great match for a standard drip coffee maker. During testing, the medium grind setting worked very well for regular pots of coffee.

    Who Should Skip It? Skip this model if you are a specialty coffee nerd. Do not buy it if you use a high-end espresso machine. It simply cannot grind fine enough for real espresso without extra work.

    Final Verdict

    The Bottom Line The DeLonghi KG79 is a fantastic entry-level tool. It brings fresh flat burr grinding to the masses. During our daily tests, it proved highly reliable. It simply works well for a basic kitchen setup.

    Known Flaws We must note its limits. This machine is very loud when running. It will not win any pro barista championships. The motor and burrs also fall short for real espresso grinds.

    The Final Call Despite the noise, this is a smart buy. It remains one of the best budget upgrades you can make. If you drink daily drip coffee, it is perfect. It is also great for a French press.
