Grinding Gourmet Coffee Beans

The fast rule of thumb is the faster the infusion the finer the grind. The objective is to get the most flavor out of your ground gourmet coffee beans when infused with hot water. The type of coffee grind that you use is important in order to properly match the type of brewing method you will be using.

The espresso brewing method need the least amount of time and requires the grind to be very fine. The various grind categories are "fine," "medium" and "coarse." The finer grinds don't need to be in contact with water for as long as the coarser grinds.

If you would like to make a stronger or weaker brew it is easier to just add or reduce the amount of ground coffee than to vary the grind. If you tried using an espresso grind in your drip filter machine, the water will take much longer to filter through and the flavor will not improve.

After deterioration expect to taste stale and coffee with a reduction of flavor. Oxygen and moister in the air quickly deteriorates ground coffee as it oxidizes and looses its flavor. The effective life of ground coffee is only a few days after grinding. It cannot be emphasized more that grinding coffee immediately before brewing makes a huge different in the freshness of your coffee.

There are a larger variety of bean grinders available on the market that can either look as a nice appliance in your kitchen or can be quickly put away. Grinding beans at home is very easy to do.

The oldest bean grinders are the mortar and pestle. This takes a while to use and the grind is not consistent. But since we are in living in the electronic age there are simpler and faster methods.

Electric motor grinders can either have blades or two crushing burr plates. The blade grinders are the least expensive and can be found at places such as Wal-Mart for under $15. The burr grinders are little more expensive. An attractive burr grinder can be found at finer food or kitchen appliance stores for $50 and above. Check out place such as Williams-Sonoma, Bed Bath and Beyond or Linens and Things.

Burr vs. Blades

Burr vs. Blades

The extra expense of a burr grinder will translate into a better grind. A blade does not really grind but slashes the beans into smaller and smaller particles. The blade particles are inconsistent; around the edges are fine powder and larger chunks in the center.

The blade grinder is the best option as someone's first grinder. It is the least expensive and can be quickly put away after use. The two major draw backs are that they are messy as the grounds spill from the container when you open it and the inconsistent grind mentioned above. Still, having a blade grinder will cause a major difference in the flavor your experience from your gourmet coffee beans if you are currently buying ground coffee.

How to Use a Blade Grinder

How to Use a Blade Grinder

When you use a blade grinder do not hold your finger on the button the entire time but push it in intervals. Grind in quick bursts of 2-5 seconds so that it prevents the beans from heating up too much. Also hold it with two hands with one over the top container and shake it up and down as you grind to mix up the contents and to give it a better consistency.

For a course grind spin your blade grinder for 7-10 seconds, a medium grind will take 10-14 seconds and a finer grind will take 15-20 seconds. If you drink espresso you will need one of the more expensive burr grinders, a blade version will not produce the consistently fine grind that is required for espresso.

One of the latest developments is a drip coffee machine with a built-in blade grinder. It has a timer you can set so in the morning the beans are automatically ground then pushed into the coffee filter and the brewing will start automatically. All you have to do is add the beans and water in the morning. This is perfect for people on the go. One of the most popular models is the Cuisinart Stainless Steel Grind & Brew, which retails for around $120. The only drawback is that a burr grinder is not available but we have hope for the future.

Burr Grinders

Burr Grinders

If you are looking for the best method for grinding your gourmet coffee beans go straight for a Burr grinder. The grind is consistent and most of the machines have various grind settings. Many include a bean hopper on top where you can store your beans with an airtight lid. Some have a setting to set how many cups you want to grind and include a receptacle where your coffee grounds are deposited. After grinding you simply pour your coffee grounds from the receptacle into your coffee maker. This type of burr grinder not only produces a great and consistent grind, it also keeps your ground coffee well contained with little spillage.

For the professional users you will find bean grinders that will grind directly into your coffee filter which is ideal for restaurants. Check out versions from Gaggia and Bunn for these types of burr grinders.

The Bottom Line

The Bottom Line

Stop settling for lower quality pre-ground store bought coffee. If you have not already done so, make the jump and get a quality grinder and buy whole bean coffee to grind just before you brew. If you are on a budget or are not ready for a larger commitment, get an inexpensive blade grinder. If you are a lover of coffee and want the best for your beans, buy a quality burr grinder. A good burr grinder will eliminate some of the hassles and spillage of a blade grinder and will produce a more consistent grind.

4 different coffee brewing methods

Here we explore the four most popular Coffee Brewing Methods: Espresso, French Press, Drip Filtration and Mokta or Stovetop method. Coffee Brewing Methods range from popular Espresso or French Press methods to lesser used methods like Turkish. Espresso The water then finds a path through the coffee grind it is referred to as the 'shot being pulled' through the group. The pressurized infusion process ensures that the water stays in contact with the coffee grounds long enough to draw out much of the coffee ground flavor. Super hot, pressurized water is forced through fine ground, tightly packed coffee. Probably the most popular of the Coffee Brewing Methods in recent times is making an Espresso using a machine. Using a course grind will still produce a good coffee, but it will taste more like a coffee produced using a Drip Filter coffee brewing method rather than true Espresso coffee. And if you didn't catch it when I started talking about Espresso, use a fine grind. Oils break down with time, and so a rich crema will be produced using fresh beans. This is produced by the pressurizing process and the oils of the coffee bean. Crema is the hazelnut foam that sits on the surface of the coffee. The sign of a good espresso, using fresh coffee beans, is the richness of the crema. French Press One of the simplest of all Coffee Brewing Methods is the French Press or Plunger. This is probably the easiest way to make great coffee! The French Press works by directly mixing ground coffee with near boiling water. The coffee flavors get drawn out into the water and then the press or plunger is depressed, separating the exhausted coffee grind from the brew. While the process has a similar taste to the Drip Filtration style, the French Press can extract more flavor from the coffee grind by extending the brewing time. Manual infusion requires you to get your timing right. If you let the brewing process run too long you may end up with a bitter coffee. Conversely, if you brew too quickly you will have a weak tasting coffee. One more point, use a course grind. You don't want fine ground coffee escaping through the metal filter and into the brew. A dusty cup of coffee is not an experience worth having. Drip Filtration
Let's start with the Drip Filtration style. Drip Filtration is probably the most popular method of all. The Drip Filtration machine works by spraying hot water across ground coffee that is held in a conical shaped filter. The hot water then slowly moves through the ground coffee. Once the water reaches the bottom of the conical filter, it drips into a container beneath it. The most widely used conical filters are made of paper, while expensive stainless steel or gold conical filters are also available. When buying paper filters, be sure to use oxygen bleached paper. Chemically treated papers may affect the taste of your coffee. Another point to be aware of with paper filters is that you may also have some of the flavorful coffee oils trapped by the paper filter. It is the oils that produce the rich crema when you make an espresso. The grind is also important with Drip Filtration. If the grind is too fine, you may clog the pores of your filter. You can avoid this by using a course grind (read about grinding here). Finally, if you do not expect to drink the full pot of coffee, either by yourself (all that caffeine....) or with friends, beware the constantly heated coffee. It loses its flavor and may even become bitter. And the golden rule....never reheat coffee.
Mokta Pot/Stovetop The Moka Pot style is also known as a Stovetop coffee pot. Moka pot's come in several sizes including 2, 4 or 6 cup capacities. The Moka Pot a simple 3 piece pot. The water reservoir is at the base, with a coffee basket in the middle and the brewed coffee ends up in the top.
The coffee brewing method is very simple. The pot is placed on a stove top which heats the water in the lower reservoir. As the water reaches boiling point, the steam rises and the water starts to push upward through the coffee grounds. This continues to travel up the central funnel and seeps into the top chamber where it comes to rest. The process finishes when the coffee stops moving into the top chamber. This should only take a few minutes to brew depending on the cup size of the Moka pot.

The grind should be a fine grind, similar or finer to that used in an Espresso machine. If you want to fill the coffee basket the way traditional Italian drinkers do, then heap the coffee grounds high in the coffee basket and screw the two pieces together. Don't worry about compacting the coffee. When the top half of the pot is screwed on, the grounds will be compacted by the filter screen. You should end up with a dry, compacted puck of coffee grounds at the end of brewing.
