Mazzer Super Jolly Timer: The Commercial Classic That Still Holds Up

Walk into almost any established coffee shop in North America or Europe, and there's a decent chance you'll spot a Mazzer Super Jolly behind the counter. This grinder has been a workhorse in commercial espresso for decades, and the Timer version adds electronic dosing that makes it more practical for both cafes and home setups. If you're considering one, here's everything I've learned about it.

I've used the Super Jolly Timer alongside modern grinders and compared the results head-to-head. It has some clear strengths and some areas where newer designs have passed it by. Let me walk you through both.

What Is the Mazzer Super Jolly Timer?

The Mazzer Super Jolly is a mid-size commercial espresso grinder made by Mazzer, the Italian manufacturer that's been building grinders since 1948. The "Timer" designation means this version has electronic timed dosing instead of the old manual doser (that star-shaped chamber with the lever).

With the Timer model, you press a button, the grinder runs for a set number of seconds, and stops automatically. You program the time to match your desired dose weight, so you get roughly the same amount of coffee each time without manually counting or weighing.

Specs at a Glance

  • Burrs: 64mm flat steel burrs
  • Motor: 350W, single-phase
  • RPM: 1,600
  • Hopper capacity: About 2.7 pounds
  • Weight: 27.5 pounds
  • Dimensions: 8" wide x 11" deep x 23" tall (it's tall)
  • Grind adjustment: Stepless worm gear system
  • Dosing: Electronic timer with two programmable buttons (single and double)

The 350W motor is more powerful than the Mazzer Mini's 250W motor, which means faster grinding and less bogging down under load. The 64mm flat burrs are the same diameter you'll find in popular home grinders like the DF64, but Mazzer's commercial burrs are built for higher volume and longer life.

Grind Quality and Espresso Performance

The Super Jolly produces a grind profile that's been the backbone of commercial espresso for years. The 64mm flat burrs create a clean, balanced particle distribution that works well across a wide range of espresso recipes.

Compared to modern boutique grinders with aftermarket SSP burrs, the Super Jolly's stock burrs produce a slightly more traditional espresso profile. You get good body, solid sweetness, and a round flavor. It's less about razor-sharp clarity of individual flavor notes and more about a well-balanced shot that tastes great with milk.

Dialing In

The stepless worm gear adjustment is one of my favorite things about the Super Jolly. You turn a knob on the side that moves the burrs incrementally closer or further apart. It's smooth, precise, and easy to make micro-adjustments. Unlike some grinders where you're fighting with a collar or ring, the worm gear feels intentional and controlled.

One tip: the adjustment moves slowly by design. It takes several full turns to go from espresso to drip grind range. This is a feature, not a bug. It means each small turn changes the grind size by a tiny amount, giving you fine control in the espresso range.

Timer Accuracy

The electronic timer works well for repetitive dosing. You program your single and double shot times, and the grinder delivers consistent amounts. There's some variance (usually within 0.3-0.5 grams) due to bean density and static, but it's accurate enough for a busy cafe workflow.

For home use, I'd still recommend weighing your output on a scale rather than trusting the timer alone. Bean moisture, origin, and roast level all affect how much coffee grinds in a given time. A scale removes the guesswork.

Retention: The Elephant in the Room

Like the Mazzer Mini, the Super Jolly has notable grind retention. Expect 3-5 grams of coffee to stay trapped in the burr chamber and chute after each use. In a commercial setting where the grinder runs continuously, this is meaningless because old grounds get pushed out by new ones constantly.

At home, retention is a bigger deal. Your first shot of the morning will contain stale grounds from the day before. Switching between beans means contamination for several doses.

Managing Retention at Home

Here's what works:

Purge a few grams first. Grind 3-4 grams and toss them before pulling your actual shot. This flushes out stale grounds. It wastes a little coffee, but the shot quality improves.

Single-dose with a bellows. Remove the hopper, weigh your beans, drop them in, grind, and then use a bellows or air puffer to blow out retained grounds. It adds steps to your workflow but gets retention down significantly.

Use it hopper-fed and accept the trade-off. If you go through 4+ doses per day of the same beans, the retention cycles out fast enough that it barely affects taste. Load the hopper Sunday night and grind through the week.

Size and Noise Considerations

The Super Jolly is big. At 23 inches tall with the hopper on, it won't fit under most kitchen cabinets. The 27.5-pound weight means it's stable on the counter (a plus), but moving it is a two-hand job. Make sure you have the counter space before buying.

Noise is moderate for a commercial grinder. The 1,600 RPM motor produces a steady hum that's noticeable but not as sharp or whiny as the Baratza Sette. It's louder than a Eureka Mignon but quieter than a Rancilio Rocky. Not a whisper, but tolerable for home use.

New vs. Used: Where the Value Lives

A new Mazzer Super Jolly Timer costs $800-$1,000. At that price, you're competing against modern single-dose grinders that have less retention, smaller footprints, and features designed for home use. The Niche Zero at $700 or a DF64 with SSP burrs at $550 are arguably better home purchases at similar price points.

But the used market is where the Super Jolly becomes a compelling buy. Cafes upgrade their equipment regularly, and used Super Jollys show up for $200-$400. At that price, you're getting commercial-grade grind quality for the cost of an entry-level consumer grinder. Slap on a new set of burrs ($50-$60 from Mazzer) and you have a grinder that'll last another decade.

When shopping used, check for:

  • Burr wear (measure the diameter; replace if significantly below 64mm)
  • Motor noise (it should hum evenly, not rattle or grind)
  • Adjustment collar play (the worm gear should turn smoothly with no dead spots)
  • Doser vs. Doserless (make sure you're getting the Timer/doserless version)

FAQ

Is the Mazzer Super Jolly good for home espresso?

Yes, especially if you buy used. The grind quality is excellent for espresso, the build is nearly indestructible, and replacement parts are cheap and available. The downsides for home use are the large footprint, high retention, and the fact that it's designed for hopper-fed workflows rather than single dosing.

How does the Super Jolly compare to the Mazzer Mini?

The Super Jolly has a more powerful motor (350W vs. 250W), larger body, and the same 64mm burr size as the Mini's 58mm. The Super Jolly grinds faster and handles higher volumes more comfortably. For home use, the Mini's smaller size might actually be an advantage if counter space is limited. Grind quality is very similar between the two.

Can I convert a Mazzer Super Jolly doser to doserless?

Sort of. Mazzer sells a doserless chute kit that replaces the doser. The conversion costs about $100-$150 for the parts and takes an hour or so. Alternatively, some people just remove the doser and 3D print or buy a simple chute adapter. It's not as elegant as a factory Timer model, but it works.

How long do the burrs last on a Super Jolly?

Mazzer rates the 64mm flat burrs for approximately 550-660 pounds of coffee. At home usage of 1 pound per week, that's over 10 years. In a busy cafe, you might replace them every 1-2 years. New burr sets cost $50-$60 from Mazzer dealers.

The Verdict

The Mazzer Super Jolly Timer is a commercial grinder through and through. It wasn't designed for home use, but it works there if you're willing to accommodate its size and retention. Buy it new for $800+ and you're paying too much compared to modern alternatives. Buy it used for $200-$400, put in new burrs, and you've got one of the best-value espresso grinders available. That's the move.
