Our take
The Costco item list names a De’Longhi coffee mill model DCG4T. Separate secondhand seller records tied to model DCG-4T and UPC 044387231244 describe a burr grinder; one also lists a timer. Those records do not map row 517's historical ASIN to the same physical item. De’Longhi's checked manual portal and archive yielded no DCG4T manual, and an unrelated Manuals+ page uses another ASIN and is not a manufacturer document. This is a cautious used-product candidate: inspect its model plate, electrical label, burr condition and instructions before relying on any setting, timer, capacity or voltage claim. No current offer or grind result is established.
For a buyer evaluating a physical DCG4T after confirming its label and instructions; not for hard performance, dose or electrical requirements..
Not for a verified voltage, dose target, capacity, adjustment range, commercial duty, espresso-performance requirement or current exact Amazon offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Costco's item list preserves the De’Longhi DCG4T model name as a coffee mill.
- Two seller records use the DCG-4T model and same UPC, offering clues to check on a physical unit.
- The saved review excludes unsupported third-party manual details instead of treating them as manufacturer facts.
What to weigh up
- No De’Longhi manual or specification sheet for DCG4T was found in the saved source check.
- The row's historical ASIN is not mapped to the seller records; timer and burr claims remain secondary.
- Voltage, capacity, settings, dose behavior and current offer cannot be confirmed.
The key details

What the features mean for you
A model clue, not a complete specification
Costco Japan's item list identifies a De’Longhi coffee mill as model DCG4T and says the model number is on the bottom of the unit. That helps a buyer check whether a used appliance carries the same code. It does not establish a complete grinder design or connect row 517's historical ASIN to another marketplace listing. The exact-model seller pages use DCG-4T and the same UPC, but remain seller records. Treat DCG4T as a cautious model candidate until the physical label and documentation agree.
Do not assume the timer behavior
One secondhand seller record mentions a timer, but there is no located De’Longhi operating manual to explain whether it is a run timer, cup selector or another control. A third-party Manuals+ page is tied to ASIN B00004RGAF and is unrelated to the historical row. The saved research excluded that page's detailed claims. As a result, a shopper who needs automatic stopping or saved single/double portions cannot count DCG4T as a match. Inspect the control panel and obtain instructions for the exact appliance before relying on the timer label.
Electrical and capacity questions stay open
A used-item listing reports 120 V and 24 tablespoons, but those fields are not mapped to the row's physical machine. The manufacturer source checked here gives only the model name, and the seller values conflict with the unrelated manual-page content. The profile therefore leaves voltage, bean load and grounds capacity unknown. That matters for installation and for any capacity filter: tablespoons in a seller entry do not establish the bin size of this candidate. Read the rating label, inspect the containers and confirm the instructions before purchase.
A cautious burr-grinder comparison
Seller records classify the DCG-4T as a burr grinder, which may help identify a physical used item, but no manufacturer source confirms the burr geometry, material, setting range or grinding behavior. The coffee-mill label alone does not demonstrate espresso suitability. A buyer can use the model code and UPC as verification questions, then compare the actual grinder with products whose dose controls and maintenance steps are documented. The saved evidence contains no performance test, customer-review summary or current offer.
Who should keep investigating DCG4T
A buyer who has found a physical De’Longhi DCG4T may continue if they can confirm the label, condition and operating instructions. Someone who needs a dependable voltage match, weight dosing, a stated hopper capacity, known duty or measured espresso performance should choose a better-documented candidate. The row's ASIN did not yield a readable exact-item match and no current Amazon offer was verified. The tracked model search can locate candidates, but it cannot validate model identity, stock or condition; confirm those details directly before paying.
What else to compare
Before you buy
What is the DCG4T?
Costco Japan's catalog identifies a De’Longhi coffee mill model DCG4T; it does not provide a full grinder specification.
Is it definitely a burr grinder?
Two used-item seller records describe DCG-4T as burr-equipped, but no matching De’Longhi manual confirms the construction.
Does it have a timer?
One seller listing says so, but the exact timer function is not explained by a manufacturer manual.
How much coffee can it hold?
A seller lists 24 tablespoons, but that quantity is not verified for row 517's physical unit.
What voltage does it use?
A used-item listing reports 120 V; check the actual rating plate because it is not mapped to the historical row.
Can it dose by weight?
No integrated scale or gram target is documented in the saved sources; do not assume one.
Is the historical ASIN a current listing?
No current exact-model offer was verified, and the row ASIN is not a live purchase link.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
