Where the sources disagree

Grinder specs

Grinder	Field	Values	What differs
1Zpresso K-Plus / K-Ultra / K-Max	Microns per step	22 (K-Plus) (Hedrick) · 20 (K-Ultra) (Chronicler, Hedrick) · 15 (K-Ultra / K-Plus) (Hedrick) · 22 (K-Max) (Chronicler)	The figures differ by model. The K-Plus is 22 µm and the K-Ultra 20 µm, and a later Hedrick video gives about 15 µm for both. The Coffee Chronicler gives 22 µm for the K-Max and 20 µm for the K-Ultra.
1Zpresso K-Plus / K-Ultra / K-Max	Adjustment	stepped (external numbered dial) (Hedrick) · stepped (Chronicler) · stepless (Chronicler)	Most sources describe a clicked external dial. One roundup video lists the K-Ultra as stepless.
1Zpresso J-Max	Microns per step	8.8 (Chronicler, Hedrick, Rowsell) · 8 (Hedrick)	Six videos from three creators (Hedrick, Rowsell, The Coffee Chronicler) give 8.8 µm. One Hedrick video gives 8 µm, which may be rounding.
Kingrinder K6	Burr size (mm)	48 (Hedrick) · 32 (Hedrick)	Two videos give 48 mm and one gives 32 mm.
Pietro Pietro (Pro Brew / multi-purpose burrs)	Burr type	conical (Hedrick) · flat (DGC, Hedrick) · flat (58 mm) (DGC)	Some Hedrick videos list it as conical and others as flat. Daddy Got Coffee consistently says 58 mm flat.
Millab M01	Burr type	conical (Chronicler, Hedrick) · flat (Chronicler)	The reviews describe a stacked conical (pineapple) burr. One roundup video lists it as flat.
Baratza Encore ESP	Microns per step	18.8 (Hedrick) · about 18 (Hedrick) · 8 (Hedrick) · 19 (Rowsell) · just over 18 (Bluebird)	Hedrick (two videos), Kyle Rowsell and Bluebird Coffee Roastery give about 18 to 19 µm per step in the espresso zone. One Hedrick video gives about 8 µm. The higher figures may differ only by rounding.
Niche Zero	Adjustment	stepless (Hedrick, Hoffmann, Quan, Rowsell, Sprometheus) · stepped (Hedrick)	Nearly every video (Hedrick, Hoffmann, Rowsell, Sprometheus, Brian Quan) describes it as stepless. One Hedrick video lists it as stepped.
Fellow Opus	Microns per step	16.6 (Hedrick) · 50 (DGC, Hedrick, Rowsell)	Four videos (Hedrick, Daddy Got Coffee, Kyle Rowsell) say 50 µm per step on the main dial. One gives 16.6 µm (possibly the micro-adjust wheel).
Option-O Lagom 01	Burr size (mm)	98 (Hedrick, Sprometheus) · 102 (Hedrick)	One Hedrick video gives 98 mm and the full Hedrick review says 102 mm. Sprometheus says the stock set is 98 mm with an optional 102 mm set, which may explain the split.
Turin SD40	Burr type	conical (Hedrick, Rowsell) · flat (Hedrick)	Three Hedrick videos and Kyle Rowsell describe it as conical. One Hedrick video lists it as flat.
Turin SD40	Adjustment	stepped (Hedrick) · stepless (Hedrick, Rowsell)	Two Hedrick videos describe it as stepped (some owners mod it to stepless). One Hedrick video and Kyle Rowsell describe it as stepless.
Turin SD40	Burr size (mm)	40 (Hedrick, Rowsell) · 38 (Hedrick)	The Hedrick review and Kyle Rowsell say 40 mm. The 2024 Hedrick tier list says 38 mm.
Weber Workshops EG-1	Adjustment	stepless (5 µm divisions) (Hedrick) · stepped (Quan)	Hedrick's review describes 5 µm divisions held by a pin and is recorded as stepless. Brian Quan calls it stepped (Hoffmann also mentions locking steps).
Kafatek Monolith M98V	Brand	Coffeetech / Kafatek Monolith M98V (Hedrick) · Mahlkönig (EK/M98V-type) (Hedrick)	The full review names the Monolith. The 2026 beginner video credits a 98 mm M98V to Mahlkönig.
Eureka Mignon Oro (single dose)	Burr size (mm)	64 (Hoffmann) · 65 (Rowsell, Sprometheus)	Hoffmann says the burrs are really 64 mm though the grinder is sold as 65 mm. Kyle Rowsell and Sprometheus give 65 mm. May be rounding or marketing.
Option-O Lagom Casa	Burr size (mm)	38 (DGC) · 48 (DGC, Sprometheus)	One Daddy Got Coffee video gives both 38 mm and 48 mm, and Sprometheus gives 48 mm.
Option-O Lagom P80	Burr set	Mizen 80 mm (DGC) · Mazzer (DGC) · in-house blind 80 mm (Sprometheus)	One Daddy Got Coffee video mentions Mazzer burrs. The video description and Sprometheus describe Option-O's own (Mizen) blind burrs.
Mx. Cool Aries	Adjustment	stepped (lockable, 25 µm) (DGC) · stepless (Chronicler)	Daddy Got Coffee describes lockable 25 µm steps. The Coffee Chronicler describes a numbered dial that is stepless between numbers.

Starting settings that differ between creators

These aren't mistakes. Each creator used a different coffee, recipe and zero point, so the numbers spread out. Every row is also on the grinder's own page, marked with who gave it.

Recipes

Where one video gives a recipe more than one way, for example spoken on camera and written differently in the description, every version is kept as its own labelled row in data/recipes.json and the recipes. We haven't picked one as right.

Recipe	Version	Pours	By	Source	What differs
Flat-bottom or cone dripper (Kono and Origami mentioned)	as described (three pours)	Three 100 g pours every 30 s. The coarser grind keeps the flow moving and avoids a stalled filter.	Bluebird	6:09	Five pours are mentioned first, then three 100 g pours are described. The three-pour version is the one recorded here.
Origami Air with a V60 paper (four-pour version from the video description)	video description: four 50 g pours	0:00, 50 g (30 g in the centre, 20 g in circles). 0:30, the same 50 g again. 1:00, 50 g in circles. 1:30, 50 g in circles.	Bluebird	2:33	The spoken recipe uses two 100 g pours 1:20 apart. The recipe written in the video description uses four 50 g pours 30 s apart. Both are kept.
Origami Air with a V60 paper (two-pour version as spoken)	spoken: two 100 g pours	Two 100 g pours, 1:20 apart, as described on camera.	Bluebird	2:33	The spoken recipe uses two 100 g pours 1:20 apart. The recipe written in the video description uses four 50 g pours 30 s apart. Both are kept.

Chemex, moka and batch guides

The roaster and maker guides added for Chemex, moka and batch don't agree with each other. Every recipe is kept as its own row in the recipes, and we haven't picked one as right.

Chemex ratio.
- Blue Bottle gives a dose range, 36 to 46 g for 600 g of water, which runs from about 1:13 to 1:16.7.
- Verve uses 1:15.
- Stumptown (42 g to 700 g) and Hoffmann (60 g per litre) both work out to 1:16.7.
- Counter Culture says 1:17, but its own 45 g and 750 g also make 1:16.7.
Chemex water temperature.
- Counter Culture uses 93 °C (200 °F).
- Stumptown and Verve use 96 °C (205 °F).
- Blue Bottle gives a range of 93 to 99 °C.
- Hoffmann gives no figure.
Chemex grind and brew time.
- Stumptown, Counter Culture and Blue Bottle say medium-coarse, and Verve says medium.
- Hoffmann advises against grinding much coarser to make up for the thick paper, and accepts a 4 to 5 minute brew instead.
- Total times run from 3:30 (Verve) to 5:30 (Blue Bottle).
Chemex bloom. Blooms run from about twice the dose (Blue Bottle 80 g, Counter Culture 100 g) to about 3.5 times (Verve 50 g for 15 g, Stumptown 150 g, stirred). Bloom times run from 30 s to 45 s.
Moka starting water.
- Bialetti's Moka Express page says to start with room-temperature water on low heat. It gives no dose, so it isn't a recipe row.
- All four roaster guides use hot water instead. Coava uses 96 to 99 °C, Stumptown and Ozone use water just off the boil, and Compass preheats it. Compass warns that cold water can scorch the grounds.
Moka tamping. Ozone presses the coffee down gently. Stumptown and Compass level it without packing, and Bialetti says not to press it.
Moka grind. Stumptown uses a drip grind, about as fine as table salt. Coava says fine but not espresso-fine, and Ozone just says fine. Stumptown's is noticeably coarser than the others.
Moka ratio, time and when to stop.
- By water, Ozone is about 1:7, Coava about 1:9 and Compass about 1:11.
- Coava brews until the pot steams, at about 4:00. Stumptown and Compass stop earlier, when the stream turns honey-coloured.
- Ozone's one cup takes about 60 s.
Batch ratio. The guides run from 55 to 70 g per litre.
- La Cabra uses 70 g/L (1:14.3).
- Market Lane uses 60 g/L (1:16.7).
- Allpress uses 56 g/L (about 1:18).
- Breville's SCA-certified Gold mode uses 55 g/L.
- Bluebird's Ratio Six recipe uses 1:15.
Batch bloom on a Moccamaster.
- Allpress closes the basket's slide gate for a 30 s bloom.
- Market Lane brews with the basket open from the start.
- La Cabra skips a bloom and stirs at about 20 s.

Temperature, roast and grind

The Brew matrix shows a range for each roast and lists these next to the method they affect, without settling them. The full wording and timestamps are in Temperature, roast and grind.

Light-roast espresso: finer, or coarser with a longer ratio? Lance Hedrick (2022) and Sprometheus go finer. Lance Hedrick (2023, 2025) prefers coarser with a longer ratio and a faster shot.
How hot for light-roast espresso? James Hoffmann uses 90 to 95 °C. Lance Hedrick went up to 96 °C for dense washed coffees in 2022, and uses around 90 °C for light or Nordic shots in 2025.
Temperature before or after grind? European Coffee Trip changes the temperature first, while Sprometheus treats it as a last resort.
Ultra-light filter: as hot as possible, or capped? James Hoffmann brews as hot as possible, and Lance Hedrick used 95 to 97 °C in 2024. In 2025 Lance Hedrick capped ultra-light, gently processed coffees at 93 °C, and in 2026 he brewed at 91 to 93 °C.
Do all light roasts want a finer grind? James Hoffmann grinds light roasts finer. Bluebird grinds dense washed Kenyans coarser, and Asser Christensen notes that light-roast Ethiopians may want a few steps coarser.
Hot or cool AeroPress? James Hoffmann uses water off the boil for light roasts, while European Coffee Trip's guests prefer 85 to 88 °C or a low-temperature competition recipe.

Topics where views differ or changed

Each topic page keeps every creator's position in its own section instead of merging them. Changes in Lance Hedrick's own view over time are dated on the page.

Summarised in our own words from the creators' videos, with every point linked to the moment it comes from. Notchbook isn't affiliated with or endorsed by any of these creators, so please watch the originals for full context. Sources
