Coffee

A coffee grinder is a must have for anyone who loves coffee, for two simple reasons:

1. Freshness
2. Control over the Coarseness of the Grind

Freshness

To keep coffee as fresh as possible you need to minimise its contact with air. Air is one of coffee’s worst enemies as it destroys delicate flavours by turning the natural oils present in coffee rancid.

If you have a coffee grinder at home you can grind your coffee beans as and when you need them. This preserves their freshness, as a whole coffee bean has a much smaller surface area than that of a ground bean and therefore is less exposed to air.

The actual process of grinding releases many of the coffee’s aromatics; as you grind you can smell this in the air. If you don’t quickly use these grounds then you are going lose this aroma and deprive your cup of valuable flavours. This is another good reason to only grind coffee on demand.

Control over the Coarseness of the Grind

Different coffee makers require a different coarseness of ground coffee. For example: an espresso machine, which has a short brewing time (less than 30 seconds), needs a very fine powder-like grind; whereas a cafetiere, which has a long brewing time (3-4 minutes), needs a much coarser grind.

With your own coffee grinder you get to control the coarseness of the grind as you can adjust the grinder’s setting. So if you find that your coffee tastes bitter, a result of over-extraction, then you can adjust the grind to a coarser setting; and if your coffee tastes flat, a result of under-extraction, you can adjust the grind to a finer setting.

Blade Vs Burr Coffee Grinders

Coffee grinders come into two categories:

1. Blade Grinders
2. Burr Grinders

A blade grinder works in a similar way to a food processor: there is a set of spinning metal blades which roughly cut through the coffee beans. The coarseness of the grind is determined by how long the grinder is left running. Coffee ground by a blade grinder is inconsistent in size as some beans will be sliced through more times then others.

Rather than chopping the coffee beans into tiny pieces, a burr grinder crushes the beans between two pieces of burred metal. A burr grinder produces a much more consistent size of grounds as the coarseness is controlled by how close the two pieces of metal are set to each other: i.e. a smaller distance for fine grounds and a larger distance for coarse. For this reason, burr grinders are far superior to blade grinders.

Why is Consistency Important?

The ultimate aim when making coffee is to extract the maximum amount of flavour whilst leaving behind bitter compounds and caffeine. This is why different coffee makers require a different coarseness of grounds. However, if your grounds are inconsistent then the larger particles in the grounds are going to be under-extracted, leaving behind flavour, and the smaller particles are going to be over-extracted, releasing bitter compounds and further caffeine into the cup. Unfortunately, the two don’t balance each other out; instead you have a flat, bitter coffee that will keep you awake for hours.

Choosing a Coffee Grinder

The coffee grinder you choose should depend on for what type of coffee maker you’re grinding the coffee. If you’re using a cafetiere or stove-top espresso maker then a hand grinder is perfectly adequate, although they do require plenty of physical effort to get results.

However, for an espresso machine a good quality electric burr coffee grinder is essential. As making an espresso is a pretty intense process (its all over in less than 30 seconds) the margin of error for the grind is very slim. This is why you need a grinder which allows for minuscule adjustments to be made so you can get the grind spot on.

here are so many types of coffee that you would find it really difficult to say which one is the best. Of course, a lot depends upon the personal taste as well. However, when it comes to judging the quality of the coffee, the smell, flavor and richness of taste are a few factors that are taken into consideration such the quality of beans, the grinder you use and the time elapsed from the preparation of the coffee cup.

Why Coffee Grinders Are Important?

The truth is that without coffee grinders you would never been able to taste a cup of coffee. Boiling the beans directly would never give you the taste of this magical beverage that has people all over the world craving for it. The type of coffee you have would very much depend upon the way ad the time your coffee beans are ground.

For example, if you love espresso the beans need to be totally powdered for the right taste; if you want to use the coffee in coffee pots, it is best to have the coffee coarsely ground as these would release the flavor slowly over a longer period of time.

There are two major types of coffee grinders available today in the market. The first utilizes blades which rotate and quite literally chops the beans into pieces. Your actual consistency of the powder will depend on how long you ruin it and the speed at which the grinder runs. To control the powder you get – if you let it run on a slow speed for less time, you would get coarse coffee; if it were to run for a longer time at a higher speed you then would get superfine powder for your espresso.

How Do The Coffee Grinders Work?

Burr Grinders are the other type of coffee grinders also known as burr grinders, use grinding wheels. What these grinders do is to permit you almost a complete control over the grind you get on your beans. They come in two varieties – there is one shaped like a cone and one that is flat. The cone shaped unit, because it does not plug up as easily as the flat one, is preferred.

Then, you have the electric models which run on plain old household electricity. In answer to the growing popularity of coffee, these grinders come in portable sizes. You can but these very affordably with prices starting under $20 American. This makes them easy to take every where.

Why People Love Coffee Grinders?

Today you find all types of coffee ground and not-ground in the market making it easy for you to pick up any type of coffee and use it. Why then the coffee grinder is still so much in demand? The answer to this question lies in the flavor of the coffee made with freshly grounded powder – as you would have guessed, the taste and flavor can never be compared with anything ready made.

First, let’s talk about why you should use coffee grinders for better coffee. Most people don’t bother to grind their own coffee. This is purely because of convenience. I hear excuses like “I don’t have the time,” or “coffee grinders make too much noise”, or “I don’t want to clean up the mess” and on and on. The simple fact is this: you should grind the coffee just before you brew it. Here’s a simple test. Go ahead and open up a can of ground coffee. Smell the aroma? Now go ahead and grind some coffee at the supermarket. Smell the bag. Do you smell the difference? Well, you’ll taste the difference too. The reason for grinding the coffee is to get more surface area to extract more coffee taste. As soon as you grind the coffee, the grounds are exposed to air and the flavor and aroma begin to dissipate. You should brew the coffee immediately after using the coffee grinder for maximum flavor.

Coffee Grinders – Cheapie Blade Grinders

The cheapest type of coffee grinder is the blade grinder. Blade grinders work like your blender does. Spinning blades chop the coffee until the desired grind size is achieved. The benefit is that the blade grinder is inexpensive. The problem is that the coffee is ground unevenly. To the coffee expert, this yields a cup of coffee that is uneven and undrinkable. My take on this is that it is still better than not grinding the coffee yourself. All is not lost, however. On to a better option.

Coffee Grinders – The Burr Grinder

Burr grinders are used by professionals for good reason. Metal discs called burrs are set apart by a precise distance. Coffee beans are ground until they are the size of the gap between the burrs and they fall down the chute into the hopper. The benefit is an even grind. This results in a better coffee experience. The better burr grinders have precision settings for all types of coffees and brewing machines.

If you want a better cup of coffee, use a coffee grinder and grind the coffee beans immediately before brewing. If you want even grounds for smoother flavor, get a burr grinder. Take these two pieces of advice and you’ll be on the way to your best cup of coffee yet. There are many more topics and articles on coffee on our website. Please take a moment to visit us.

For the best flavor possible from your coffee beans, grind them yourself. Adding to that philosophy, use only beans that were roasted within the past ten days to get the freshest flavor. Beware of beans that are too new, though. Beans that have been roasted only within the past day or two are full of carbon dioxide. It will get released into your cup of coffee, causing it to turn sudsy.

There are two main types of grinders on the market: blade grinders and burr grinders. Burr grinders are also known as mills. Each type of grinder has its benefits and drawbacks, and you must decide which qualities are the most important for you.

Blade Grinders

These are the easiest and cheapest coffee grinders. A metal blade inside the grinder spins rapidly, chopping the coffee beans. The result is coffee flakes that are uneven in size, often causing the taste of the brewed product to be inconsistent.

There are generally no settings to tell the machine how coarse or how fine to grind coffee. It is up to the user to determine how long to let the grinder run to achieve the desired level of fineness.

Blades build up heat while grinding. If you are trying to grind coffee to make espresso, you will have to allow the blades to run for a long time. This causes them to get hot, which can in turn give the coffee a burned taste.

If you want a good, basic grinder for everyday use, you can find them in nearly every home goods or department store for approximately $30.

Blade grinders are fantastic for basic day-to-day coffee consumption, but if you want more finesse in you flavor, you need to move to a burr grinder.

Burr Grinders

Typically referred to as mills, burr grinders crush the beans uniformly between a grinding wheel and a stationary surface. There are two types of burr grinders.

Wheel Burr

This is the less expensive form of burr grinder. The grinding wheel spins very quickly to crush the beans, and the fineness of the grind depends upon where the grinding wheel is set. These grinders can be noisy and can get quite messy.

Conical Burr

The burr spins much slower in these grinders, making them quieter and cleaner. These grinders are more expensive, but will not clog and can be used to grind oily or flavored beans.

In addition to wheel burr mills and conical burr mills, there is also a wide assortment of handheld grinders. Due to the very nature of the handheld grinder, the wheel is turning much more slowly, which means it is not building up heat. If you desire a very fine grind for something such as espresso, you will get the best results and maintain the most flavor with a handheld burr mill.

Beautiful, heirloom-quality solid wood, handheld burr mills can be found for around $80 to $100. Modern, electric burr mills will run anywhere from $150 to $200 for very good ones.

How Fine to Grind

There are essentially four main grinds you need to concern yourself with. There are some others in addition to these, but the ones listed below will get you well on your way to becoming a coffee connoisseur.

o Extra Fine is nearly powder, much the consistency of sugar. Extra fine ground beans are used to make espresso.

o Fine could be described as just slightly coarser than table salt. Fine coffee would be used in pots or automatic drip machines with a conical filter.

o Medium would be much like the consistency of sand, and would work best in automatic drip coffeepots with flat-bottomed filters.

o Coarse coffee will have distinct particles or flakes. This is the coffee you would want to use in a French press or old-style percolator.

The finest coffee of all is Turkish coffee. This must be ground to a baby-fine powder, and many times must be finished off in a mortar and pestle after being ground in a burr grinder. Even the best of grinders cannot always get coffee as finely ground as it needs to be for Turkish coffee.

Never use your coffee grinder for anything other than coffee. Many people use their coffee grinder to chop up spices or herbs, or even to chop medicine for children or pets. It is extremely difficult to remove every foreign particle in the grinder, so save yourself some trouble and keep the coffee to itself. Use a food processor to chop other things such as herbs or spices. This way, the flavors will not be able to intermingle, and your coffee will remain pure.

Many modern coffee makers incorporate a grinder into the piece of machinery. This is a convenient way to grind and brew all at the same time. You will definitely get what you pay for, though. Cheaper models will most certainly have a blade grinder, while the more upscale versions will come with a burr grinder. Pay close attention to the product description so you know exactly what product you are receiving. This is particularly important if you enjoy finely ground coffees such as espresso.

Did you know that approximately 1.4 billion cups of coffee are drunk every single day worldwide? With an estimated four-out-of-every-five Americans consuming no less than four-hundred-million cups of coffee a day.

With so many people enjoying coffee, it stands to reason that coffee enthusiasts want to try and improve their brew.

I can tell you right now that if you’re making coffee from instant or bought pre-grounded coffee you can significantly improve the taste by investing in a coffee grinder.

The reason is very simple, only coffee beans that you grind yourself offer the freshest and generally better tasting coffee – period… This is because when you purchase pre-grounded coffee the grounds are already likely to be past their best due to prolonged air exposure that is totally out of your control.

You see, when coffee grounds are exposed to air they start to oxidize. If you love coffee this is bad news and the results can often mean a ruined brew. So throw away any instant or grounded coffee that you have in your kitchen – there is a better way…

All you need to start making the perfect cup is a coffee grinder and some coffee beans. There are two basic types of grinder to consider that we’ll discuss.

The Blade Style Coffee Grinder:

Theses are the least expensive type of coffee grinders and utilize a metal blade to slice up the coffee beans. The main problem is that you control how long the slicing occurs and so it is extremely difficult to achieve an even grind that all too often leads to an inconsistent brew.

Another pitfall is because the blade has to spin very fast to slice the coffee beans the potential for heat-build up is extremely likely. This again is bad news for any coffee enthusiast as the results can a ruined brew.

That said, choosing a blade style coffee grinder is still a step-up from pre-purchased grounds or instant.

The Burr Style Coffee Grinder:

A coffee lovers dream, a burr grinder is widely considered to be the best way of grinding coffee. There are two variants, the wheel based burr and the conical burr. Both are extremely efficient a producing a consistent, even grind every time.

They work by crushing the coffee beans between a rotating grinding wheel and a fixed surface. The ability to manually adjust the burr to the desired height enables the coffee lover to experiment with a multitude of brews whilst still producing uniform grounds.

Of the two types, the conical is considered the better. More expensive than it’s cousin it is able to rotate far slower making it quieter and that generally means less mess too.

It’s a fact that conical burr grinders produce the best tasting coffee. For more information, including some great deals and our must read review of the new Rancilio Rocky doserless coffee grinder make sure you visit us toady…
