Grinding your beans is an important step in the pursuit of caffeinated nirvana, and the best way to produce the freshest coffee.

Granted, you can get some very good pre-ground coffee, but as long as they're stored correctly (a largely but not totally airtight container, in a cupboard rather than the fridge) beans will last longer than pre-ground, and unleash more flavour when put through a grinder.

With an unprecedented number of grind settings, stainless steel conical burr grinder and intuitive LCD control system with LED screen, the Sage Smart Grinder by Heston Blumenthal is an obvious winner here. However, we also rate the cheap and cheerful De'Longhi KG79 and, above all, the superb high-end Niche Zero.

How to choose the best coffee grinder for you

There are three main types of grinder on the market: burr, blade and manual. Ask a barista, and they'll always choose burr, here's why.

Blade Grinders (£10-£50) work just like a kitchen mixer, smashing and slicing up the beans using small, exceptionally sharp blades. While quick, cheap and compact, blade grinders don't produce the most consistent coffee grounds, while the speed of the blades can burn the beans, altering the taste. 

To be frank, if you tell a coffee expert you use a blade grinder, they will laugh in your face. However, maybe the joke's on them: these versatile machines may not be the best for coffee but they are great for blitzing spices for cooking.

Burr grinders (£40-£2,000) slowly crush the beans instead of smashing them up. They offer a more uniform grind to blade models and more expensive grinders can be adjusted so you can produce a fine grind for high-pressure espresso machines, or a looser mix for filter and French Press. 

Look for either ceramic, stainless steel or hardened steel grinders, and opt for conical, rather than wheel burrs for a quieter, gentler, grind.  

Hand Grinders (£10-50) offer a more traditional approach, and while time consuming and laborious, the grind can be excellent. The opposite to blade grinder, if you tell a coffee expert you use a manual device, you will get double Hipster points for your person-powered, artisanal approach to a flat white.

The best coffee grinders, in order of grandness

1. Sage Smart Grinder Pro

The best coffee grinder

Grinder: Stainless steel conical burr
Grind settings: 60
Power: 165W
Reasons to buy
+Bomb-proof build+Accurate dosing +Intuitive design
Reasons to avoid
-Not budget priced

The previous Sage coffee grinder the 'Dose Control Pro' has been providing faultless bean smushing every morning for the last 5 years, round T3's way.

Now its replacement, the stainless steel Smart Grinder Pro offers the same industrial quality, usability and professional results, and continues to put most domestic grinders to shame.

Thanks to the large blue LCD screen you can clearly see what type of coffee you're grinding, and choose between cafetiere, filter, percolator or espresso. 

With no fewer than 60 grind settings, you can fine tune the results quickly and easily, something we've only seen before on more expensive pro models. Once you’ve chosen the grind, it's a simple matter of selecting the number of shots and then either accepting the calculated grind time, or adjusting it manually, to produce the perfect amount of coffee for a specific machine or method. 

You can also adjust the machine's presets, tailoring it for your own coffee machine or personal taste. 

What really sets it apart from the rest of the domestic machines is the ability to grind directly into your coffee machine's Portafilter (the handle sticking out the front with the coffee in it). To that end, it comes with two cradles, one for domestic, one for professional sized machines. 

This is incredibly convenient for espresso lovers and cuts down on mess. You can also use the supplied plastic airtight container, or grind direct into paper filters.  

And speaking of mess, the huge 450g hopper can also be removed so switching between bean varieties is mercifully simple – because it only grinds what you need you can quickly switch between decaf and regular beans without contamination - while the removable grinds catcher reduces the amount of mess on the worktop significantly. 

Making coffee is usually a messy business, but this provides so many solutions to that, it verges on OCD.

Features mean nothing without performance, but the step-up in grind quality and consistency here is exceptional, with an espresso grind every bit as fine as a shop-bought packet. 

It's not cheap, but if you're serious about your coffee, it's not that expensive, and it is well worth the investment.

best coffee grinder 2020: De'Longhi KG79

2. De'Longhi KG79 Professional Burr Grinder

Best value coffee grinder

Grinder: Ceramic wheel burr
Grind settings: N/A
Power: 110W
Reasons to buy
+Exceptional value+Slick design
Reasons to avoid
-Occasional grind inconsistency

At a quite incredible price, this monolithic design looks the business, can grind 2-12 cups worth of beans, and has a dual safety system, that cuts power if either the bean hopper or grounds container is removed during operation. 

Despite being all-plastic it's reassuringly robust.

The minimalist design only has one niggly issue – a lack of numbers on the coarseness dial means there's an element of guesswork involved in choosing your perfect grind. 

That's only really a problem if you're constantly switching between espresso, filter and cafetiere, however. Most people will find a preferred setting and either leave it there forever, or make small variations to suit the age and type of bean being ground.

Okay, you will find some variation in the coarseness of the grind, particularly with the finer settings, where a few larger chunks of bean can squeeze through into the collector. 

It's not a deal breaker, but as with most non-professional grinders – don’t let the product title mislead you, this is still very much a domestic machine – anyone used to only the finest of fine grounds for their espressos might occasionally be left wanting.

3. Niche Zero

The best small prosumer grinder you can buy

Grinder: Hardened steel 63mm conical burrs
Grind settings: Infinite
Power: N/A
Reasons to buy
+Exquisite performance+Small footprint+Infinite adjustability+Zero retention+Really quiet

•Buy the Niche Zero directly from Niche Coffee

Any of the electric grinders on this page will appease the vast majority of freshly ground coffee lovers. But for the true coffee connoisseur or trained barista, nothing but the very best grinder will do; we’re talking big industrial-looking machines that cost between £400 and £2,000 a throw and come with names most of us have never heard of, like Mahlkonig, Baratza and Mazzer.

According to those in the know, a good quality grinder noticeably improves flavour and strength and lets you produce coffee to rival the best coffee shops. Well this young upstart from Niche – a crowdfunded enterprise – is causing quite a stir among coffee aficionados and luckily we’ve had our hands on one for the past few weeks.

The Niche Zero has been described as a prosumer model so it’s as much for home use as it is for small cafés. It’s much, much smaller than the majority of high-end grinders (just 30cm tall and 15cm wide) and so simple that any creature with opposable thumbs could use it.

The Zero is equipped with a premium 63mm ‘food grade’ conical burr set powered by a small DC motor. On the side is a silver on/off switch and on the top an ingenious twist ring to set the grind levels from coarse to fine. This large tactile ring turns in smooth increments from ‘course’ through ‘filter drip’ to ‘espresso’ and ‘fine’, with the finest setting producing a ground of true Talcum powder consistency.

One facet that has had coffee cognoscenti twittering on the web is the Niche Zero’s ability for zero retention (hence the name). This means that if you fill the provided silver cup (which incidentally fits perfectly into the average portafilter for mess-free filling) with 18.5 grams of coffee beans, the machine will dispense 18.5 grams of pure ground coffee powder, leaving only a few negligible grains in the machine. This may seem a bit over the top but to coffee nerds it’s is a very important thing indeed.

Available in black or white, this elegant looking grinder is far and away the most efficient model on this page and the best looker – we love the natural oak details – but its price (£499) pops it down a couple of spots in the list. Nevertheless, for coffee connoisseurs looking for a premium grinder that delivers in spades, is really quiet and effortless to use, this one's a bit of a Holy Grail that may well transform your coffee sipping experience.

best coffee grinder 2020: Dualit Burr

4. Dualit Burr Coffee Grinder

Solid, competitively-priced option

Grinder: Stainless-steel conical burr
Grind settings: 10
Power: 150W
Reasons to buy
+Large hopper+Easy clean+Portion control
Reasons to avoid
-Not ideal for espresso

Here, a large 250g bean hopper combined with the ability to control the amount of beans ground via a simple dial (2-10 cups) helps avoid wasting fresh coffee. 

It's a good deal for what it costs but if you're looking for an exceptionally fine grind for a pro-style espresso machine, you may need to stretch your budget past the 60-or-so quid this will cost you. 

It also suffers from a quite infuriating build-up of static around its plastic grounds collector. 

Given Dualit's industrial toaster heritage, we were expecting a classy metal construction, so the plastic feel was a bit of a disappointment.

Even so, this is a good-looking machine, and the features and performance more than make up for it any material short-comings. 

best coffee grinder 2020: KitchenAid Burr Grinder

5. KitchenAid Burr Grinder

Lower-tech Sage alternative

Grinder: Stainless-steel conical burr
Grind settings: 15
Power: 185W
Reasons to buy
+Easy fineness adjustment+Battleship build+Extreme redness
Reasons to avoid
-Fragile looking collector-Quite pricey

So we recently got a cold brew coffee maker and were alarmed to find it required the grinding of an entire bag of beans to use it.

Luckily, this KitchenAid grinder was to hand and did the job with zero fuss. 

That was on one of its lower grind settings, which are great for drip and cold-brew machines, and cafetieres. Dial it up and you get properly fine espresso grinds. Although the dial is numbered one to eight there are also half stops in between each of those, giving 15 grind settings in all.  

This suffers slightly in comparison to the similarly-priced Sage in that it doesn't have a dosing function, but it is somewhat sexier, and better for those who don't like all that hand holding. 

You can even take it apart and manually adjust the burrs if the presets aren't quite to your liking. Surely nobody is ever going to actually do that, but it's nice to know you could.

-Takes practice-Lower quality results

Costing less than a week's worth of takeaway coffees, this compact twin-blade design will assuredly not win favour from 'proper' coffee lovers, who dislike the supposedly flavour-destroying heat and lack of grind control inherent in this type of grinder.

Its main purpose is to produce a super-fine grind, suitable for most espresso machines, making it an ideal first upgrade for coffee bean converts. 

Although it can handle enough beans in one go to make 15 cups, results are noticeably more consistent if you grind fewer beans at a time, and limit it to short bursts, to avoid overheating.

It's also capable of a coarser grind for cafetieres and drip machines, but you'll really have to practice for that.

Also good to know: the safety lid cuts off power instantly when removed, hopefully preventing any pinkie amputations, and it is great for grinding spices. Although maybe don't use it for both that and coffee unless you take your latte curried.
