SD40 vs DF64 Noise Level Test


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.

    Quiet, Powerful, and No Retention

    Posted by Keith on 23rd Jun 2022

    I love this little grinder! Its build quality is quite impressive. It's all metal, except for the grind selection wheel and locator (and the very bottom of the base) - and obviously the bellows. Feels and very solid. It has a pleasing, powerful sound that is not too abrasive. It makes short work of beans, even on a fine setting that I use for espresso. I have the polished aluminum version, with clear bellows and a wood top. It looks great on the counter. But probably the best thing is that it really is zero retention. 18g in, 18g out. The bellows helps push that last little bit out with a few pumps. Highly recommended!

    First big girl grinder

    Fully obsessed! Take it with a grain of beans because it’s my first legit grinder, but I am super impressed with the quality of the grinder. I also love the look of it, I got the wooden lid and it adds such a cool modern look. I’m not ultra-concerned about retention, and I’m pulling amazing shots, so I’m pleased.
