Ninja does not document any of its blenders as a coffee grinder, and for one of the three models this page used to recommend it says the opposite outright. The current SharkNinja owner’s guide covering the BL456 lists, among its numbered safety instructions, “DO NOT perform grinding operations” and “DO NOT process dry ingredients without adding liquid to the Single-Serve Cup. They are not intended for dry blending.” For the BL610 and BL770 we could not establish one consistent answer: the guide revisions we were able to read disagree with each other about whether dry grinding is prohibited, and we are not willing to tell you a manufacturer permits something on evidence that thin. What is not in dispute is that neither guide contains any coffee instruction, and neither lists a grind you could brew espresso with. Treat dry grinding as not sanctioned on any of these models. If you want ground coffee, use a grinder.
An earlier version of this page said the answer was “YES” and “a resounding ‘yes'”, and named the BL610, BL770 and BL456 as “the most effective” models for the job. That was wrong. It also told readers that 15–20 seconds of blending produces “a fine grind (best for espresso)” — a blade device cannot produce an espresso grind at any blending time, for reasons set out below. And its cleaning section ended at the words “Follow these steps:” with no steps after it. All of that is corrected here, using Ninja’s own documentation.

What each named model’s owner’s guide actually says
These are the three models the old page named. Every quotation below is from the owner’s guide SharkNinja itself publishes for that model, opened in August 2026.
| Model | What Ninja’s own guide says | What that means for coffee |
|---|---|---|
| BL456 (covered by the BL450 Series Nutri Ninja Pro guide, which names BL456 in its SKU list) | Safety instruction 30: “DO NOT perform grinding operations.” Instruction 40: “DO NOT process dry ingredients without adding liquid to the Single-Serve Cup. They are not intended for dry blending.” | Explicitly prohibited. Not a grey area, not a “do it gently” — the manufacturer says don’t. |
| BL610 (BL610 Series guide) | Revisions we could access disagree on whether dry grinding is prohibited. No coffee instruction in any of them. Treat as not sanctioned. The Blending Chart’s nearest entry is MEDIUM — “grate hard cheeses, beat dips, grind nuts, and thoroughly chop”. Assembly note: “Add liquid ingredients first and then dry ingredients.” The warning block opens “Do not use appliance for other than intended use.” | Not rated for it. Coffee appears nowhere in the guide, and the only dry-ingredient instruction assumes liquid is already in the pitcher. |
| BL770 (BL770 Series guide) | The Speed Settings & Uses table in the revision we read lists a Grinding function — but as Bowl / Chopping Blade Assembly / speed 2 / Meat, not beans. Other revisions appear to prohibit grinding outright, so treat dry grinding as not sanctioned. A separate Grating row covers “Grated cheese, Bread crumbs, Spices”. An earlier revision of the same guide adds: “CAUTION: We do not recommend grinding in any of our Nutri Ninja® cups.” | A grinding function exists, but not for this. Coffee is not listed in any row, and the cups the old page pointed at are the ones Ninja singles out. |
So the honest answer is model-specific, and none of the three versions of it is “yes”. One model is told not to. The other two are simply not documented for the job, which matters when something goes wrong. SharkNinja’s one-year limited warranty covers the unit “when it is used under normal household conditions and maintained according to the requirements outlined in the Owner’s Guide”, and its exclusions list “Damage caused by misuse, abuse, negligent handling”. Using an appliance for something its guide never describes is exactly the argument you would have to win.
Why a blade cannot give you an espresso grind
A blade device does not grind. It smashes beans repeatedly at high speed and you stop it when the average looks right — which leaves boulders and dust in the same batch. The National Coffee Association puts the limit plainly: with a blade grinder “You can’t ensure a consistent grind, which impacts taste”, and it recommends a burr grinder because burrs “are better for the types of coffee that require smaller grind sizes, like espresso or French press” (NCA, drip coffee).
Notice what a real grind specification looks like. The Specialty Coffee Association defines its cupping grind by particle distribution, not by time: the coffee “shall be ground so that 70–75% of the grinds pass through the 20 US standard mesh sieve (850 µm aperture)” (SCA Standard 102-2024, §5.2.3). No number of seconds in a blender gets you a stated distribution — and espresso, which needs the finest and most uniform grind of any common method, is the furthest thing from what a blade can do. Water finds the channels through the dust and races past the boulders, and the shot fails.
If you have no grinder right now
- Buy the coffee ground. Ask the shop to grind for your brewer. Freshness is lost faster once ground, so buy smaller and more often.
- Brew the whole beans. There are methods that work without grinding at all — see how to make coffee with whole beans without grinding. Slower, and it costs you nothing in equipment — but read that page first: steeping whole beans has its own food-safety question if you start hot and let the pot sit.
- Buy a burr grinder. It is the single piece of equipment that changes the cup most, and it is the one the NCA actually recommends.
Disclosure: the product link in this section is an affiliate link. As an Amazon Associate I earn from qualifying purchases. We have not tested this grinder ourselves; it is named because it is a widely available conical burr model, not on the basis of any measurement by us. A common entry point is the OXO Brew Conical Burr Coffee Grinder. Whatever you buy, dose by weight rather than by scoop.
On dose: the SCA’s own brew ratio is 55–60 g of coffee per litre of water, which it describes as “approximately 17:1 to 18:1 water-to-coffee ratio” (SCA Standard 102-2024, §5.3). Work at 1:18 by weight and adjust from there — and note that stronger means more coffee, not less water-to-coffee restraint. A coffee “cup” in brewing terms is 6 fl oz (about 177 mL), not 8, so a 6 oz cup at 1:18 is about 9.7 g of coffee. For water temperature, this site’s brew temperature page already states the SCA range correctly.
Cleaning a Ninja blender (the steps that were missing)
The old page promised cleaning steps and then printed none. Here they are, taken from Ninja’s Care & Maintenance instructions rather than invented:
- Unplug the motor base first.
- Separate all parts from each other.
- Hand-wash the pitcher, lid and blade assembly in warm, soapy water. Ninja’s instruction is to use “a dish-washing utensil with a handle to avoid direct hand contact with blades”. Rinse and air-dry thoroughly.
- If using a dishwasher, Ninja specifies the lid and blade assembly go on the top rack, and that the blade assembly is removed from the pitcher first.
- Wipe the motor base with a clean, damp cloth. Ninja’s guide adds: “DO NOT use abrasive cloths, pads, or brushes to clean the base.” Never immerse the motor base.
Two operating limits worth carrying over from the same guides, whatever you are blending: “Do not run the appliance over 4 minutes at a time to prevent overheating”, and if the unit does overload, its thermal switch cuts the motor and you unplug it and let it cool roughly 15 minutes before resetting. Those numbers are Ninja’s, not ours.
