Ditting · Flat burr807 Lab Sweet
An 80mm cast-steel-burr single-dose grinder built for cupping labs and cafes that has become a cult pick for home espresso and filter obsessives who want one grinder to do it all.
The short version
This is a bag grinder wearing a home-bar costume: a lab/shop tool from a company that has made burrs since 1928, repurposed by enthusiasts for its uniquely sweet, syrupy cup.
Accept the size and the price before you accept the coffee, because both are commercial-grade.
Why people buy it
- 80mm cast-steel burrs give a genuinely distinct cup character: dense body and pronounced sweetness that owners consistently single out
- Near-zero retention out of the box makes it legitimately single-dose capable despite being built as a bulk/shop grinder
Why they don’t
- Large commercial footprint and height (over 21 inches stock) that will not fit under many kitchen cabinets
The full tally
- 80mm cast-steel burrs give a genuinely distinct cup character: dense body and pronounced sweetness that owners consistently single out
- Near-zero retention out of the box makes it legitimately single-dose capable despite being built as a bulk/shop grinder
- Stepless adjustment spans Turkish to cold brew, so it actually covers espresso, filter, and everything between on one dial
- Commercial-grade simplicity and parts availability from an 90+ year old manufacturer means long-term serviceability most boutique single-dosers cannot match
- Large commercial footprint and height (over 21 inches stock) that will not fit under many kitchen cabinets
- Premium price for a home setup, and the base retail hopper/platform config is overbuilt for anyone grinding under 20g at a time
- Dialing in fine espresso settings has a real learning curve according to owners, and the standard configuration needs aftermarket mods (Sworks single-dose kit, ESP fork) to feel truly home-optimized
What the community knows
Years of owner threads, distilled — strongly recommended.
Reference-grade flat burr platform with proven Hemro/Mahlkonig heritage, exceptional build, and remarkable serviceability—but QC alignment issues and a genuine learning curve on espresso mean this is for committed prosumers, not stepping stones; once dialed, its burr geometry…

Worth knowing before you buy — Most experienced owners reframe this as "buy the 804 if you prioritize proven simplicity and Swiss build; buy the 807 LS if you want modern looks, Peak burrs, and will dial in alignment yourself"—suggesting the 807 LS appeals to patient…
Known weak points — Burr alignment variance on arrival (documented across multiple units 2021-2022, appears improved in recent batches); owner reports of poor service response from some dealers when shimming attempted; occasional reports of high retention with thicker metal flappers.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners rarely outgrow the burrs, they outgrow the stock hopper and platform: most serious home users add a Sworks single-dose hopper or move to the purpose-built Prima-collab 807 Lab Sweet ESP configuration with the low-profile hopper and portafilter fork for a tighter footprint and true small-dose workflow.

- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs pull syrup — naturals and classic medium roasts play straight into their character.

Common questions
Is the Ditting 807 Lab Sweet good for espresso at home?
Yes, though it is a commercial/lab-oriented grinder rather than a purpose-built home espresso grinder. Owners report a real learning curve dialing in fine espresso settings, but once dialed the 80mm cast-steel burrs produce a notably sweet, dense-bodied shot.
How much retention does the 807 Lab Sweet have?
Manufacturer and retailer copy describes it as close to zero retention, and an owner report on Home Barista measured about 1g unseasoned dropping to near 0g after a few doses.
What is the difference between the 807 Lab Sweet and the standard 807 Shop grinder?
The Lab Sweet is the only 807 model equipped with the premium cast steel burrs and their special grinding teeth geometry, which Ditting says spreads particle size to boost sweetness and consistency versus the standard 807 burrs.
