The number and variety of espresso machines available today can be a little intimidating but it is helpful to remember that there are really only four major types:
Manual
While the oldest style of espresso machine, the manual machine is also by far the most difficult to master as it involves learning how to consistently work a piston that forces water through the coffee grounds. For those who love the ritual of brewing and claim to be espresso purists, a manual espresso machine promises all you want in a single package but of course with an effort.
Semi-automatic
Typically the least expensive of the four types of machines the semi-automatic is probably the most common home espresso machine. The user manually starts the brewing cycle by the on/off switch and stops the process in the similar way when the extraction completes. Semi-automatic machine gives the user a control over the quality of the espresso but do not usually come with a grinder. To develop good froth for cappuccinos and lattes, you use what is called a steam wand.
Fully-automatic
There is not a great difference between fully and semi-automatic machines except for the fact that with a fully automatic espresso machine the user has no control over the extraction process once they have turned the unit on. There is little difference in espresso quality but of course the benefit is that there is very little in the way of skill necessary to operate a fully-automatic machine.
Super-automatic
As the name suggests these machines pretty much take care of everything for you. Jura Capresso makes a number of very popular super-automatic espresso machines such as the Impressa C5 and Impressa J5. The machine will grind the coffee, tamp the ground beans into the filter and extract the concentration to your preset volume. There are usually several controls available to adjust things such as strength and amount brewed. These machines represent the latest in technology but of course they usually carry a price tag to match. The Jura Impressa Z5 sets the benchmark in ultimate super-automatic espresso machines currently on the market.
If you take the time to figure which type of espresso machine you need you should find the whole buying process much easier.

Coffee has five primary ways of being brewed. Each method has brewing variables – introduction of water, brewing temperature, and separating the brewed liquor from the coffee grounds. These five methods are called Turkish brewing, concentrate brewing, percolating, drip brewing, and French Press brewing.
“Turkish” or “Greek” Coffee
Turkish coffee or kahve is the traditional name is made in small containers directly on the flame with water and finely ground kahve comes to a boil. Often times it is brewed up with sugar already introduced. In some traditions they will pour off a little into each cup and then bring it to a second boil, pouring the rest off into each cup insuring an even distribution of grounds. In some regions they serve the kahve with added spice which is usually cardamom. The coffee is not filtered from the liquor which leaves a thick pungent and muddy brew. The mud settles to the bottom of the tiny demitasse cups the coffee is served in. In many countries they read the coffee mud after you have drank your coffee and tell you your future.
Concentrate Brewing
Concentrate brewing is very popular in Latin America and other parts of the world. It is beginning to make a come back in the U.S.. Concentrate brewing takes large amounts of coffee that is brewed with small amounts of water to brew a concentrate. To make a cup of coffee you mix some of the concentrate with hot water. The concentrate is brewed either hot or cold. When it is brewed cold you must let the coffee sit for at least a day. This method creates a mild light-bodied coffee with little aroma and a little acidity with a muted flavor.
Percolating
This procedure involves a continuous brewing of the coffee grounds using boiling water which then turns to boiling coffee liquor brewing over the grounds. This method is practical but is an insult to the coffee bean. Brewing with boiling water is bad enough, then boiling the liquor is asking for a thin, bitter and tarry coffee.
Though this produces an awful cup of coffee many people still prefer percolation. If its for you then more power to you!
Auto drip
This is the most popular way to brew coffee in the U.S.A. Pouring hot water over grounds in a filter and letting the brew drip out the bottom, simple. Drip brewing can produce an excellent cup of coffee if the proper equipment is used. One of the biggest issues with auto drip machines is they don’t brew at the right temperature. Bunn is one of the few companies which calibrate their machines to the proper temperature. If you have a good auto drip brewing machine then the next hurdle to tackle is the filter. Paper filters can deposit a flavor in the coffee and also do not allow a lot of the coffee oils and organic compounds through. A gold-plated reusable filter is the perfect option for drip brewing. It will not deposit a taste in the coffee and doesn’t trap as much of the coffee’s essence as paper filters do.
French Press or Press Pot
French Pres brewing gives you complete control. It is more labor intensive than auto drip the brewing variables can be better controlled. Coarsely ground coffee is placed in a glass carafe. The hot water is then poured over the grounds. When the brewing is complete the top is placed on and a plunger that consists of a metal mesh plate is pressed down pushing the grounds to the bottom. The coffee liquor is on top ready to be poured off. The mesh filter allows the oils and fine coffee particles through without a problem. Also because a coarser grind is required a longer brewing time is required. A general rule of thumb is four minutes for a French press. This direct contact of the grounds to water allows a more complete, controllable, and even extraction. Even with the coarse grind though a coarse grind will still produce some fine particles. A cup of French-pressed coffee will be fuller, more body, and more flavor. It will also have sediment on the bottom of the cup.

Air is the enemy of all coffee drinkers. Once air comes in contact with your coffee grinds, they begin to lose their flavor. Coffee manufacturers vacuum seal their grinds to keep them fresh while they sit on the shelves at the supermarket but once you break that seal, it’s all downhill from there. Buying whole coffee beans and grinding them yourself is a great way to ensure that your coffee remains as flavorful as possible. But do you know how to grind your coffee beans properly?
Different types of coffee calls for different types of grinds. So you’ll need to learn to use your coffee grinder properly if you want to make the freshest best tasting coffee possible.
If you plan on brewing your coffee with a percolator or a French Press coffee maker then you’ll need a coarser grind. Place the coffee beans in your coffee grinder and tap the grind button a few times as you would use the pulse feature on your food processor. The goal is to break the beans up so that they look like tiny pieces of coffee bean. If they look like a powder, then you need to slowly back away from the coffee grinder and start again. Remember to tap the button and not hold it down.
Automatic drip coffee makers work best with medium grinds. Picture the grinds that you’d find in a can of supermarket coffee. Those are medium grinds. They can be described as looking like brown sand. So remember the last time you went to the beach but instead of seeing the sand in between your toes, imagine seeing sand in your coffee maker. Once again, while holding the coffee grinder button, don’t get carried away and over grind your coffee beans. You do not want a fine powder if you’re going to use an automatic coffee maker.
Finally if your using an espresso maker, you want those fine powdery grinds that you’ve been trying to avoid when making coarse and medium grinds. So grind away until your heart is content.
Grinding your own coffee beans right before you brew your coffee is a great way to make sure that you’re getting the freshest cup of coffee possible. But a fresh cup of coffee can still be bitter or weak. Learning how to grind your coffee beans is an important part of making great coffee.

Could there be anything better than a hot, fresh brewed cup of coffee? As you open that can of pre-ground Maxwell House Coffee, did you even know that coffee comes in different roasts? Did you know that you can roast your own coffee beans at home? If you think that the aroma of your fresh ground coffee beans can’t be beat, get a home coffee roaster, you’ll be in Java Heaven.
Roasting the coffee beans is what imparts flavor. Similar to the making of a fine wine or a hand rolled cigar, some consider the roasting of coffee beans as an art. Those that describe coffee use some of the same vocabulary they use to describe wine. Depending on the roast level chosen the beans take on different flavor characteristics. The lighter the coffee bean the less flavor it will have, the darker the coffee bean the stronger the flavor it will have.
There are generally four different categories of roast. A light roast (American) , a medium roast (Breakfast), a dark roast (French), and darkest roast (Italian or espresso). Each type of roast imparts a different appearance to the coffee beans.
When a coffee bean is roasted to an American roast the beans will have a very light color to them and they will appear dry. A medium roasted bean, or Breakfast roast will have a rich brown color and will be oily in appearance. A French roasted coffee bean will have a very oily appearance with the beans appearing very dark brown. The darkest roasted beans or Espresso beans will appear black.
Coffee roasting can easily be done in your home. Depending on the roast that you desire you can roast coffee in five to fifteen minutes. Green beans are available online from a number of sellers, as are coffee roasters. Choose different types of green coffees to sample. Drum roasters are very popular for use in the home. It’s best to consider purchasing a roaster as it will give you the most consistent finish to your beans. Some try to roast beans in frying pans, some use hot air popcorn poppers. While each of these techniques will work, as mentioned above they don’t give a consistent finish to all the beans and you will most likely be disappointed in the result.
Enjoy!

Today, I will propose to you how to make a great cup of coffee. You can do it. There are a few secrets to the process. I will share these with you.
Start with the bean and pick your roast. Quality coffee can only come from a quality coffee bean that is properly roasted. The process of roasting a coffee bean is complex and can result in a given bean tasting very different depending on how it is roasted. If you desire a strong intense flavor to your coffee, choose a dark roast (ex: French Roast). If you like to a light flavor, less intense, choose a lighter roast.
Never use pre-ground coffee. Pre-ground coffee will lose its flavor and essence within a short period of time. Grinding before you brew will assure you that no flavor is lost due to time.
Always use cold filtered water when brewing your coffee. The water you use represents 98% of your cup of coffee. Filtering the water will remove impurities that could affect the taste. Poor quality water can come from a variety of sources. Example, older house will have older pipes. Theses pipes tend to give the water an off flavor. You will want to remove this by filtering. The basic rule is the better the water, the better the coffee.
Skip the paper filters and go for the gold. Yes, these are 23k gold plated stainless steel filters. Paper filters will influence the flavor of the coffee in a negative manner. The Gold plated filters influence the flavor by allowing natural oils to infiltrate into your brew, adding a level of flavor and aroma you wont find with paper coffee filters. Another plus is that these filters can be reused over and over, and will last a very long time. Not only will your coffee be better, but you will be helping the environment by saving on waste.
Never over do it on the add-ins. Cut down on the sugar, cream, and other flavor add-ins to really enjoy the true essence of the brew. If we disguise the coffee to much; we will never know the true taste.
Part of what makes a great cup of coffee is how and when we enjoy it. We all have our favorite time and rituals. For me, nothing beats enjoying a great cup of coffee on a Sunday morning and reading the paper.
