Cuisinart · ThermoblockEspresso Bar Grind & Brew Espresso Machine (EM-640)
Cuisinart's flagship all-in-one semi-automatic with a built-in conical burr grinder, 54mm bottomless portafilter, assisted tamping, and a cold extraction mode — a wide-feature package priced at the competitive boundary with Breville and De'Longhi.
The short version
The EM-640 packs a grinder, assisted tamper, cold-extraction, and manual steam wand into one cabinet at a price that puts it in direct competition with more refined machines.
What you must accept is that there is no PID, no pre-infusion, and the grinder's wide 16-setting range hints at a breadth-over-depth compromise.
Why people buy it
- Built-in conical burr grinder with 16 settings covers espresso-to-coarse in one machine, eliminating a separate grinder purchase for beginners
- Cold extraction mode dispenses room-temperature espresso without dumping hot liquid over ice — a genuinely useful feature for iced drinks
Why they don’t
- No PID temperature control and no programmable pre-infusion — both are available on directly competing machines (Breville Barista Express, De'Longhi La Specialista Arte Evo) for roughly the same street price
The full tally
- Built-in conical burr grinder with 16 settings covers espresso-to-coarse in one machine, eliminating a separate grinder purchase for beginners
- Cold extraction mode dispenses room-temperature espresso without dumping hot liquid over ice — a genuinely useful feature for iced drinks
- Generous 75 oz front-loading reservoir and top-loading cup warmer plate reduce daily maintenance interruptions
- 3-year limited warranty substantially outlasts the 1–2 year coverage of Breville, De'Longhi, and Ninja competitors at this price
- No PID temperature control and no programmable pre-infusion — both are available on directly competing machines (Breville Barista Express, De'Longhi La Specialista Arte Evo) for roughly the same street price
- Large cuboid footprint (~16 × 15 × 16 inches) dominates a counter more than most comparably featured grind-and-brew machines
- Steam wand reported by multiple reviewers as slow and prone to splashing; reaching true microfoam requires patience and technique that the hardware does not reward consistently
What the community knows
Years of owner threads, distilled — well regarded.
Built-in grinder and integrated workflow genuinely lower the beginner barrier and deliver acceptable espresso out of the box, but proprietary parts, limited serviceability, and documented durability concerns make it a capable entry point you will eventually outgrow — the frother…

Worth knowing before you buy — Most owners wish they had invested the difference into the grinder separately and used a manual machine to learn lever technique.
Known weak points — Frother wand durability concerns; proprietary portafilter and parts limit long-term serviceability.
“The frother wand was perhaps the trickiest aspect of this machine to get to grips with, although that's no different to other models I've tried with this functionality.”
“Delivers a consistent great grind for espresso from the whole bean holder, large water reservoir for multiple brews, solid construction with high-quality materials, and produces excellent foam and steamed water from the frother.”
“The built-in grinder is a standout feature — it offers multiple grind settings, so you can really customize your espresso exactly how you like it. The quality of the espresso is rich, smooth, and full-bodied, with a beautiful crema every time.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who dial in technique and grow frustrated by the absence of PID temperature stability and pre-infusion typically move to the De'Longhi La Specialista Arte Evo or Breville Barista Express at similar street prices, or the Breville Barista Pro for active temperature management. The 54mm portafilter is a dead end for aftermarket accessories — an upgrade path almost certainly requires a new machine.

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 machine gets blamed for it. While you learn it, a forgiving medium-light roast keeps dial-in kind — bright enough to taste progress, sweet enough to drink the misses.

Common questions
Does the EM-640 have a PID temperature controller?
No. The EM-640 does not include a PID. Competing machines at a similar street price — such as the Breville Barista Express and De'Longhi La Specialista Arte Evo — do include PID or active temperature management.
What does the cold extraction mode actually do?
It brews espresso at room temperature rather than running a hot shot. This means you get a concentrated cold espresso directly into your cup without dumping hot liquid over ice and diluting the drink.
Can I use pre-ground coffee?
The EM-640 includes single and double shot filter baskets. There is no dedicated bypass doser, but pre-ground coffee can be loaded directly into the portafilter basket.
Will it fit a 20 oz travel mug?
Yes. Cuisinart states the machine accommodates travel mugs up to 20 oz.
What warranty does the EM-640 carry?
Cuisinart provides a 3-year limited warranty, which is longer than the 1–2 year coverage offered by Breville, De'Longhi, and Ninja at this price level.
