What with your conical burr grinder, your blade grinder, your smart grinder, and a vast array of grind settings, there is plenty to think about when setting out to buy the best coffee grinder for you and your household. No one can deny that grinding your own whole beans offers you the best chance of achieving the right grind sizes, whether you end up using a hand grinder or a state-of-the-art electric blade grinder. You retain so much more of the coffee bean’s inherent aroma and taste than with pre-ground coffee and can get as close to drinking the smell your nostrils delighted in the morning, thus satisfying your taste-buds which know when the coffee just isn't up to par.
Within every coffee bean, there are essential oils. The moment a bean is a ground, these oils are released; however, they can evaporate all too easily, and a more bitter taste experience will follow. The serious coffee drinker will thus want to grind the beans as closely as possible to the moment of drinking that delicious nectar. The serious coffee drinker will also want to experiment with a range of different coffee-making methods, from press to drip to espresso, etc. so having a coffee grinder that allows at least a dozen different grind sizes is greatly beneficial in this regard.
As well as grind settings you will also want to consider whether a burr grinder or a blade grinder is best for you. They will also complement your kitchen's aesthetic look, may need to be easily stored away, and may even please you either with their relative noise or relative quiet. Whether grinding coffee at home or in the office and whichever grind settings you end up gravitating towards, however you want your ultimate cup of coffee to taste, let the grinding begin!

Features To Consider With Coffee Grinders
Burr System
A burr grinding machine is better than a blade grinding one; it creates a more uniform grind in which the coffee particles tend to end up the same size. Experts say that this is the number one difference in producing just good coffee or outstandingly aromatic coffee, that's as close in taste to smell as possible. Within burr systems there are two kinds - flat plate and conical. Flat burr grinders achieve the most consistent, even grind; however, conical grinders are less expensive and quieter. These are finer distinctions, though, and your main goal is to decide between a burr or a blade option.
Cups Per Grind
You'll need to think about what your coffee grinder will be doing, 99% of the time. This will influence your decision making with regard to which size of grinder you'll opt for. A coffee grinder that has a smaller capacity will suffice if you just intend to making coffee for yourself or a small group of friends or family. However, if you intend your coffee making to be used in the office or for regular socializing you'll likely need a larger grinder. There is no other advantage or disadvantage that comes with the size of your grinder. What really counts is the quality of burr, as discussed above. You might also want to store it away after use, so need to consider whether it is the right size to go snugly into your kitchen storage space.
Countertop Space
As mentioned, size is a factor because your grinder will have to go somewhere, and it isn't likely to be small enough to go just anywhere. If you're thinking of buying a high-quality grinder then you probably already have a high-quality coffee maker or espresso maker, so these two products could take up quite a lot of valuable countertop space. The best grinder for coffee will likely be in use fairly often, so having to store it away and take it out all the time could become quite annoying. It's all very well having the best smart grinder or best grinder coffee can handle; where will it go, on a day to day basis? And for that matter, among so many models which one will fit in your kitchen's overall theme, allowing you to become the barista you can be.
Cleaning
Reviews will generally tell you not only whether a particular coffee grinder produces a supreme grind or allows you to make a fine espresso or has a 10 grind or 60 grind capability. But a more mundane but important factor is how easy the grinder is to clean. For example, do all its main parts easily disassemble, allowing you to use a cleaning brush or dishwasher to good effect? Or does this home grinder have reviews that criticize this often ignored but important element? Over time ground coffee can actually disrupt and block your easy to use coffee grinder from maximum effectiveness. It may be a brilliant blade grinder or conical burr grinder. It may be easy to use or be voted one of the best overall manual grinders or burr coffee grinders. But is it going to be easy to clean, or will it require significant effort? Such a thing is important to know in advance. It may be that you're willing to put in the effort, so as to gain all the other benefits.
Ease Of Use
The amount of coffee ground produced is one thing, grind time another, consistent grinds still another. However, an often ignored but key question is, how easy is it to use? Does it require an awkward clicking of various parts into place? Is the plastic lid easy or difficult to remove and put back on? It might be perfect for coffee lovers or connoisseurs, but can anyone in your household use it, or only you? If it's too easy to use, is it safe for children who might meddle with it? The best grinders coffee lovers turn to will be one that can be both easy to use yet safe to have around children. But maybe you don't have children; however, they might visit when your friends or family come over. The best coffee grinders will tend to have lots of reviews over many years because so many have been sold.
Electric Vs Manual
Budgetary concerns are usually the deciding factor here; manual coffee grinding being significantly less expensive than electrical grinding. With all of its guaranteed power and grind settings, electric coffee grinders also allow you to tailor your grinding to different shades of coffee so that the needs of filter coffee, needs of an espresso machine, french press or cold can all be efficiently catered for. A manual grinder will allow you to select a grind setting but not to the extent that an electric grinder can offer.
Portability
In terms of ease of transporting and using, manual grinders can be used anywhere, not just where there are enough electrical plug sockets. Whether you want a press or cold brew you will be able to take a manual grinder in a bag or suitcase and use it whilst on vacation or camping. The best coffee grinder doesn't have to be electric, state of the art smart grinder. If you love the tactile and auditory qualities of manual grinding, as well as its retro look, then it could be the best one for you.
Settings
The models will allow you to select from a number of different settings, so you can get the best coffee for your particular taste buds. On the whole, there are two main varieties of grinders; stepped or stepless. Stepped grinders will have a number of pre-set settings, eg. fine ground, coarse ground, etc. whereas their stepless cousins offer more fluidity, permitting to gradually shift from one end of the spectrum to another, rather than having pre-set 'clicks'. Stepless grinders are a little more costly and more suited to a coffee connoisseur. If you really know your stuff, you'll like the freedom to able to peer through the translucent lid and just grind until, in your judgment, the grounds are at an optimum consistency.
Coffee Grinder FAQ
Q: How to choose the right grind size?
Consistency is king when it comes to grinding your coffee beans so as to yield the perfect cup of joe.
- Coarse Grind - Particles of coarse ground coffee bean look about the same as flecks of sea salt. It is mostly used in French press coffee, while an even more coarse 'extra coarse grind' works well for cold brewing.
- Medium Grind - This is perfect if you want to indulge in drip coffee; the taste can be subtly altered by setting slight variations within the medium grind theme. Medium ground coffee is also great for cone-shaped filter coffee; it tends to produce a more pungent, bitter taste.
- Fine Grind - This works best with Moka or espresso coffee, ie. if you want to grind coffee that will flourish for those methods of percolation. Fine ground coffee, to the naked eye, looks about as 'fine' as granulated sugar particles.
- Extra Fine Grind - This is great for Turkish coffee. This thrives on having particles that are as small and fine as possible because they dissolve excellently in water.
Q: Is it cheaper in the long run to grind your own coffee?
In general, coffee beans that you yourself grind will tend to be more expensive than pre-ground coffee, due to the more mass-produced condition in which pre-ground coffee is usually sold. In order to retain its freshness, it will often have fillers, additives, and other preservatives, thus making it cheaper. It can also be transported more cheaply because more of it can fit into fewer bags, unlike whole-bean coffee beans, which will take up more space within each bag. Certain high-end pre-ground coffee will actually still be quite expensive, while others will charge the same regardless of whether you buy it in its pre-ground or whole-bean form. If cheapness is high on your agenda, then pre-ground is perhaps best for you; either that or buying in bulk.
Q: Do you need to replace the blades on a coffee grinder?
Coffee blades can become a bit blunt over time. Among coffee beans are commonly mingled with tiny rocks and objects, while blades like any other form of metallic knives or cutting implements will naturally lose their sharpness after repeated usage. If you notice that you're tending to produce increasingly coarse coffee grounds, then this may be a telltale sign that they need replacing. Grounds can also start to get a bit thick and clumpy; another giveaway. Lastly, you might notice that your grounds are less consistent than they used to be. If so, it's probably time to change your blades. If you can get your existing blades sharpened in a local knife-sharpening or key-cutting stall then great. It will probably be easier and more effective, though, just to order a replacement set from the manufacturer or vendor.
How To Sharpen Coffee Grinder Blades?
There is, however, a DIY option in terms of sharpening your own blades yourself. You can pour some uncooked rice into the grinder bowl, grind it for around 60 seconds, as you would your coffee beans. Then, throw out the rice and unplug your machine. Use a damp cloth to wipe your blades. Voilà!
Q: Does freshly ground coffee deliver a better taste than store-bought?
As mentioned, pre-ground coffee, unless it is a high-quality brand, can sometimes contain fillers and additives in order to elongate its freshness, whereas unground coffee beans never do. At the very point when you grind a coffee bean, gasses are released and aromatic oils start to evaporate, so you ought to be doing this at the last possible point in the whole process, from coffee seed to delicious cup of coffee. Every time you open a bag of even freshly ground coffee, oxygen is getting in, which causes even more oils to dry up. Unground beans, however, tend to be larger than pre-ground beans, so take longer to dry out, thus tasting better for a longer amount of time. Grinding your own beans affords you the option of grinding it to the exact consistency you desire. The same cannot be said for its pre-ground counterpart. You only get a one size fits all approach with pre-ground coffee, so the more serious you start to take your coffee the less likely you are to purchase it. Some connoisseurs even take to roasting their own coffee beans, but that's another story!
