Availability: Black and White are currently in stock and ready to ship. This is the 110–120V, 60Hz US version.
Factory testing notice: Turin grinders are tested with coffee before leaving the factory. A new grinder may therefore contain a small amount of coffee residue in the burr chamber.
Turin SK40 Single-Dose Stepless Espresso Grinder
The Turin SK40 is a compact, mostly metal single-dose grinder built around 40mm eight-point stainless-steel conical burrs. Its worm-drive stepless adjustment makes very small grind changes easy, giving espresso drinkers substantially more dialing control than a conventional stepped grinder at this price.
A tilted aluminum body, bellows, and short grounds path support a low-retention workflow. The 150W gear motor turns at approximately 400 RPM while grinding, producing a cup profile that generally emphasizes body, texture, and balanced sweetness. Although optimized for espresso control, the SK40 can grind from espresso through pour-over and French press.

How the SK40 Stepless Adjustment Works
The SK40 uses a side-mounted worm-drive knob to rotate the grind collar gradually. This provides nearly unlimited positions between marked settings and makes it particularly useful for espresso, where a small adjustment can substantially change shot time.
The tradeoff is speed when moving between brew methods: turning from fine espresso to coarse French press takes more knob rotations than it would on a stepped or directly rotated collar. The SK40 is therefore best for someone who stays primarily within one brew range, especially espresso, rather than switching back and forth several times each day.
Turin SK40 First Look

Dialing In the SK40 for Espresso
Start with a dose that fits your basket. For example, an 18g dose with a 36g espresso yield gives you a 1:2 starting recipe for an 18g basket; adapt it to your coffee and taste. Keep dose and target yield unchanged while testing small grind adjustments.
- Use the side knob to make a small change in the required direction. Follow the SK40 user manual; do not force the mechanism or tighten the burrs into contact.
- Grind the weighed beans into the supplied cup, using the same feeding and bellows routine each time.
- Prepare the puck evenly, brew to your target yield, and record shot time and taste.
- Change one variable at a time. Once flow is consistent, adjust the recipe to improve taste rather than chasing a universal dial number.
Examples using the same dose and target yield
| What you observe |
What to try next |
| The target yield arrives much faster than intended. |
Try a small change finer, keeping dose and yield the same. |
| The shot barely flows or takes much longer than intended. |
Try a small change coarser and check that the basket is not overfilled. |
| Flow is uneven or changes greatly between identical recipes. |
Check dose, distribution, tamping and grounds buildup before making a large grind change. |
Different coffees and grinder calibration produce different usable dial positions. Record a reference for your own setup, and expect to fine-tune after changing beans or returning from a coarser brew method.
What Does the Turin SK40 Taste Like?
The 40mm conical burrs generally produce a rounded, full-bodied cup with blended sweetness. That makes the SK40 a strong match for traditional espresso, medium and darker roasts, and milk drinks. It can also prepare pour-over and other filter methods, but customers seeking maximum flavor separation from light-roast filter coffee may prefer a flat-burr grinder such as the DF54.
Single-Dose Workflow
- Weigh the coffee beans for your recipe.
- Set the grind size using the worm-drive adjustment knob.
- Start the motor and add the beans for a running start.
- Allow the grinder to finish, then use the bellows with a few controlled presses.
- Transfer the grounds from the included metal dosing cup.
- Make small adjustment changes while dialing in and record useful reference positions.
Retention and static vary with roast level, bean age, humidity, cleaning, and bellows technique. A very light spray of water—RDT—may help in dry conditions, but it is not necessary for every coffee or environment.

Turin SK40 vs DF54: Compare the Workflow
The SK40 uses 40mm conical burrs and a worm-drive adjustment knob. The current DF54 v4.1 uses 54mm flat burrs, a directly rotated adjustment collar, a plasma anti-static system, a metal declumper and an enlarged chute. Both are stepless single-dose grinders; the adjustment mechanism and selected burr profile are more useful buying distinctions than burr shape alone.

Choose the SK40 if you mainly stay in the espresso range and prefer gradual knob adjustments. Compare the DF54 if you switch brew methods more often or want its flat-burr options and static-control features. For an espresso machine, select a DF54 Espresso burr configuration; choose the separately labeled Brew option for filter-focused use. Taste also depends on burr geometry, beans and recipe, so flat versus conical alone does not guarantee a particular result.
The Moshi C63 and Turin DC63 above provide larger conical-burr alternatives. Prefer a manual option? Compare the Turin H40 V2, or browse all single-dose grinders and home espresso grinders.

Frequently Asked Questions
Is the Turin SK40 good for espresso?
Yes. Espresso is one of the SK40’s primary strengths because its stepless worm-drive adjustment permits very small grind changes while dialing in.
What cup profile does the SK40 produce?
Its conical burrs generally emphasize body, texture, and rounded sweetness rather than the pronounced flavor separation associated with clarity-focused flat burrs.
Can the SK40 grind fine enough for a non-pressurized espresso basket?
Yes. The grinder is designed to reach espresso-fine settings and provides enough adjustment control for standard non-pressurized baskets.
Can the Turin SK40 grind for pour-over and French press?
Yes. Its range covers espresso through coarse brewing methods. However, the worm-drive mechanism requires multiple turns when moving a long distance between settings.
Is the Turin SK40 stepless?
Yes. The side adjustment knob drives the grind collar gradually without fixed clicks, allowing precise positions between the printed reference marks.
What is the difference between the SK40 and older SD40 designs?
The SK40’s defining difference is its stepless worm-drive adjustment. Stepped SD40 versions are faster to move between brew methods, while the SK40 provides finer espresso control.
How does the SK40 compare with the DF54?
The SK40 has 40mm conical burrs with worm-drive adjustment. The DF54 v4.1 has 54mm flat burrs, a directly rotated collar and plasma static control. Compare the adjustment workflow and burr choices above, then choose for your primary brew method.
Is the SK40 a single-dose grinder?
Yes. It is intended for weighing and grinding one dose at a time and has an approximate 40g hopper capacity.
How much coffee does the SK40 retain?
The tilted body and bellows are designed to reduce retention, but no grinder is literally zero retention. Results vary with the coffee, grind size, static, cleanliness, and bellows technique.
Does the SK40 require RDT?
Not necessarily. A very light mist can reduce static in dry conditions, but many users will not need it with every coffee. Avoid adding excessive water.
Should I start the grinder before adding beans?
A running start can reduce the initial load on the motor, especially with dense light-roast beans at fine espresso settings.
Should I adjust finer while the SK40 is running?
If beans are between the burrs, run the motor while making a significant adjustment finer. This helps prevent coffee from binding the burrs.
How fast does the SK40 turn?
The grinder operates at approximately 400 RPM while grinding and approximately 650 RPM without beans. Actual behavior varies under load.
Is the SK40 noisy?
The geared motor has a distinctive mechanical sound. Perceived volume depends on the beans, grind setting, counter surface, and room.
Can I grind directly into a portafilter?
The intended workflow uses the included metal dosing cup, which provides a clean and broadly compatible transfer into the portafilter.
Why is there coffee residue in my new grinder?
Each grinder is tested with coffee at the factory to check operation and burr alignment. A small amount of residue in a new unit is therefore normal and does not mean it was previously owned.
Do the burrs need seasoning?
The SK40 can be used immediately. Grind behavior may become more consistent after several pounds of coffee, but there is no need to waste a large amount before use.
How should I clean the SK40?
Unplug the grinder, brush away loose grounds, and keep water out of the burr chamber and motor. Oily dark roasts generally require more frequent cleaning.
Are replacement burrs and parts available?
Yes. Espresso Outlet stocks compatible replacement burrs, bellows, dosing cups, motors, switches, declumpers, and other SK40 parts.
Is this the 120V US version?
Yes. This listing is for the 110–120V, 60Hz version intended for use in the United States.
What warranty is included?
The Turin SK40 includes a one-year warranty through Espresso Outlet, subject to the published warranty terms.
