Compatibility

Fits all DeLonghi machines with 51 mm portafilters, including La Specialista, Distinta, Dedica, and similar models. Fits perfectly into original DeLonghi portafilter without removing plastic insert.

Compatibility Notice: Please verify your exact machine model and portafilter diameter before ordering, as brands often use different sizes across models. If you are unsure, contact us before purchasing - we’re happy to confirm compatibility.

Instructions & Care

Before first use: Rinse thoroughly with warm water or run a blank shot through your machine with the basket in place to remove any manufacturing residue.

Daily cleaning: After each use, knock out the puck and rinse the basket under hot water to remove coffee oils and residue.

Monthly maintenance: Soak in a solution of espresso machine cleaner and hot water for 15–30 minutes. Rinse thoroughly before reuse.

Avoid abrasive tools: Use a soft brush or cloth to clean. Do not use steel wool or harsh scouring pads as they may damage the surface.

Storage: Keep the basket dry and store it in a clean environment when not in use.

Brewing Tips:

Grind Size: Use a fine grind, slightly finer than for a standard double basket. Consistency is key - use a burr grinder.
Dose: 8-13 g of freshly ground coffee, adjusted to your taste.
Tamping: Apply even, level pressure with a 51-51.3 mm tamper.
Extraction Time: Aim for 25-35 seconds for ~25-30 ml of espresso.
Taste Profile: Expect enhanced sweetness, fuller body, and thicker crema. Light roasts reveal fruity and floral notes; darker roasts emphasize chocolate and nuts.

Very high quality basket. I use it in a bottomless portafilter but, as advertised, it will fit into the pressurized portafilter that comes with the DeLonghi Dedica. You’ll have to use quite a bit of strength before it pops in but it works.

Excellent choice using it in a bottomless portafilter - that’s where the precision geometry truly shines. Wishing you many clean, balanced extractions ahead.

Help & Advice

Is this IMS basket compatible with 51 mm tampers?

IMS baskets are compatible with DeLonghi original and most custom tampers. Some tamper manufacturers make “precision” tampers with a very tight fit. Unfortunately, they do not leave any space for air and even small particles of coffee can make tamper to get stuck in the basket.

How to recognize an IMS basket?

Every genuine IMS basket has two engravings:

Lot number – identifies the production batch and ensures full traceability for quality control and distribution.
IMS code – indicates the exact model and dimensions of the basket.

This system guarantees authenticity and helps you confirm you’ve received the correct product.

Why was my IMS basket packaging open?

IMS packs baskets in a small cardboard sleeves that may sometimes shift or loosen in transit. This does not mean the product is used or fake. Every basket we sell is new, unused, and shipped exactly as we receive it from IMS.

Could I have received a “fake” IMS basket?

No. All our IMS baskets come directly from IMS in Italy, in their official packaging.
