Hello!! It's Joseph

    From David Schomer : A condensed list of additional features and capabilities critical to an espresso grinder includes:     a) Retention of less than 1 gram (g) of chambered ground coffee     b) Grinding output speed of no more than 2g per second.     c) Propulsion of powder into the portafilter with no clumping or micro-particle drift     d) Cessation of grinding upon achieving an exact dose by gram weight (+/- 0.1g)     e) Temperature Control: The powder must remain between 32°C to 35°C.   outcome: controlled Flow Rate. for espresso, too-fast shot that reaches full volume in less than 25 seconds will have a flavor profile dominated by sour/astringent notes. Too slow, extracting 25ml in 33 sec, and the flavor might be hollow, sour, or bitter. ( yield extraction) What features are key in maintaining an ideal flow rate of the shot? Stepless grind setting adjustments Dosing by weight Low retentio...

  It claims to have higher extraction, more sweet, less bitterness, less fines 80mm flat burr, cast steel belt driven 13000 rpm    home-barista mobile01

for practical use, 4 to 5 clicks in eg Ditting and EK43, increase the burr gap by 0.2 mm Mahlkoenig GH2: the range is from 0 to 1200 microns(1.2mm), from Turkish to Percolator   just as a rough guide: sieve: For Hario mini hand grinder, the pitch is 1mm, 7 clicks per rotation. It's not easy to find the "zero". here is my settings: espresso:  7 clicks pourover:  13 clicks (1.5 mm) french press: 14 clicks   baratza encore or virtuoso: range: (250 in encore) 200 microns to 1200 microns steps: 40 step size: 25 microns  baratza preciso: 40mm conical range: 200 microns to 1170 microns step size: 100 microns macro(40 steps), 10 microns micro(11 steps), total 440 steps   etzinger / baratza sette 270: 40 mm steel burr, from etzinger. range: 230 microns to 950 microns step size: 100 microns macro(30 steps), 10 microns micro(9 steps, stepless in baratza), total 270 steps rotating: outer burr, instead of i...

Grind by Weight:  integrated high-precision load cell ( upto 0.1 g accuracy ) ground breaking real-time scale controlled dosing for unmatched control over your espresso quality. High consistency: - DDD ( burr Disc Distance Detection) upto 0.01 mm burr size: 65mm disc motor speed: 1450 / 1600 ( 50 Hz/60 Hz) control. via LCD display and mobile app. Can save grind recipes in the app. So you can fine tune the grind profile, by setting different grind size profile, eg for a 18g grind, it can be made of 8 g of 0.14mm gap, and 10g of 0.16mm gap coming soon target to be start delivery: May 2020 website
