Difference Between V1 and V2

The look and feel of v2 is similar to v1, but v2 has a few nice improvements. First, it has a new and improved 8 point burr that provides for a more uniform particle size distribution and a better flow of grinds through the burrs (less clogging potential). Second, it has a new adjustment dial without any brew methods listed. Third it has an improved circuit board.

Breville Built In Grinder vs Turin SD40 Grinder



The Turin SD40 is a single dose grinder that uses bellows and a tilted base to reduce retention. It has 40mm stainless steel conical burrs and a sturdy aluminum body.

Most grinders in the price range of this grinder are made with plastic, smaller burrs, ceramic burrs and are not very well built and have high retention. This grinder is well built with mostly metal construction and low retention. We are excited to be the exclusive US importer for this product and we think it will do very well when compared to other grinders in it’s price range. It compares well against the Breville Smart grinder, Ascaso grinders, Baratza grinders, Fellow grinders, and does a lot better in terms of grind quality when compared to blade grinders. In terms of noise level it is quieter than a lot of the grinders in it's price range.

Grinders are tested at the factory with coffee to ensure proper alignment, so there can be minimal signs of coffee in the burrs.

    Grind Quality

    Posted by Adrian on 1st Sep 2023

    This is my first power grinder. I have arthritis in my hands and hand grinding is painful. I purchased this grinder (after watching many videos) because it appeared to be one, without breaking the bank, that could grind Turkish-style coffee. It grinds very fine when set up properly. <1 on the dial. Overall I am pleased with its performance so far. I also drink filtered coffee along with my wife but prefer Turkish.

    Nice Grinder but could be better

    Posted by Randy R. on 29th Jul 2023

    I've had the SD40 for about a month. Overall, I'm happy with it but think that there could be some improvements. Out of the box, I love the size and the weight. Very sturdy construction. After dialing it in, I found the grind quality to be excellent, but calling it "low retention" is a bit of a stretch, IMO. If not for the bellows it would retain quite a bit of coffee. Things I think could be improved: 1) Increase the size of the bellows. Add one more "pleat" so that more air can be forced through per push. Right now it takes too many pushes to remove all of the ground coffee. 2) Shorten the "fingers" on the anti-clumping gasket. They really don't do much to reduce clumping and just get in the way. 3) I wasn't happy with the large amount of change between clicks on grind adjustment ring (approx. 4 marks per click). I did some searching and found a mod online that allows the ring to stop at every mark on the dial. I 3D printed it and it works great. I now have 105 stops as opposed to the factory 36. Not "stepless" but close to it. I sold a Niche Zero for this grinder and have no regrets. If Turin would make a couple of changes (especially the bellows and the adjustment ring) they could turn a very good grinder into a great one.

    First Take

    Posted by Hooey Dee on 23rd Jun 2023

    Preordered this because we have replaced our Breville Espresso machine with the built in grinder with a Rocket espresso machine. Pros Very lightweight Grinds for espresso really fast Low Retention Very quiet Cons The magnetic cup doesn't sit still it sometimes moves in a circular motion. Always powered on which is ok but the placement of the button to start the grind is at a place where it can be pushed by accident. The power button seems a bit flimsy sometimes I have to push it twice to start/stop the grind. I've had this for about 2 weeks now and so far I like it. I've been trying to find more videos on it to teach me some tricks and tips to use it better for my espresso shots.
