Most of us love a good cup (or two) of coffee in the morning and maybe another to keep us going in the afternoon on a busy day.

But most of us, unless we’re really hardcore about our coffee preference or are involved in producing coffee beans, don’t usually think about what a quality coffee bean is or where they come from.

So, I’ll be going into what makes a quality coffee bean and the countries they’re commonly grown in. And also how coffee is roasted and decaffeinated.

What Makes a Quality Coffee Bean?

As with a lot of things, freshness is a key factor in the quality of beans. The best coffee beans are vacuum sealed under two weeks from roasting and brewed under two hours from grinding them.

Location also matters. High grown Arabica beans are usually considered the best.

This isn’t directly to do with the bean, but another factor is the cleanliness of your coffee pot and mineral content in your water. Scale can alter the taste of your coffee brew…

How do you sense a good bean when it’s brewed? Aroma, how it smells, is your first impression. Floral and nutty are indicators of a good quality and fresh bean.

Of course, there’s also body and taste. Body, how thick and rich the coffee is, is another way quality is measured. A French Pressed coffee is usually more rich because it retains more of the bean’s natural oils.

As far as taste goes, bitterness, at least to a degree, is actually a desirable trait in a coffee bean.

Where is Coffee Grown?

The coffee tree is a tropical evergreen shrub, so it grows in an environment that is warm or hot and gets a lot of rain. It’s also typically grown at a high altitude (usually very hilly places or mountains), at least Arabica beans. Because of this, coffee beans are usually handpicked.

There are two main commercially grown types of coffee beans. Arabica and Robusta. Arabicas need a temperature of around 15-24 C to grow. Robustas need a temperature of 24-30 C and can be grown at just above sea level.

So, to answer the question a little more directly, mainly South American countries…

How is Coffee Roasted?

Now that we know how to pick a quality coffee bean and where they’re grown, how is coffee roasted?

For commercial roasting, the beans are sorted into a hopper first, then moved to the roaster by conveyor belt. Then they’re roasted until they reach a temperature of 175 C or 347 F. Then the temperature may be adjusted. When the roasting is done, they’re moved again to be air cooled with a draft inducer.

Coffee beans lose about 15-18% of their weight due to water loss during this process, but can double in size.

The Decaffeination Process

For those of you who can’t have caffeine for health reasons or just want to cut down, but still love the taste of coffee, you might be wondering, how do they remove the caffeine?

This process is done before roasting, while the beans are still green and there’s four main ways to remove caffeine. Two using solvents and two without solvents.

The two solvents that are commonly used are methylene chloride and ethyl acetate.

There’s also two ways to use these solvents. The beans can be soaked directly in solvent, or the solvent can be added to the water used to soak the beans after, so it never touches the beans.

Then there’s the Swiss Water Process and the CO2 (or Carbon Dioxide), which don’t use solvents.

The Swiss Water Process begins by soaking the beans in very hot water to dissolve the caffeine. Then the water is drawn off and passed through an activated charcoal filter. The beans are discarded and the water is reused to soak a new batch of beans.

With the CO2 method, water soaked beans are put in a stainless steel container. The container is then sealed and liquid CO2 is forced into the coffee at a pressure of 1000 pounds per square inch. The CO2 is then transferred to a different container, where the pressure is released and the CO2 goes back to a gaseous state and the caffeine is removed. The CO2 is pumped back into a pressurized container and reused.

So, no matter where you buy your coffee or whether you buy regular or decaf coffee, enjoy your next cup and appreciate the work that goes into it. If you need a source, check out this Best Espresso Beans for the Money content. Cheers!

Are you discontented with the sound being produced by your car audio system? Is it too plain? Does it lack the extra oomph? Whatever you say, car owners always have the right to complain about their own car stereos since they are the ones who mostly benefit from it the moment the play button is pressed. More so, each car owner has different musical definitions and that definition extends to the music or sound being released by different vehicular stereos. Do you think it needs an extra boost? Well, there are three solutions that could be done to fix that problem. Just choose one or two, and you’re good to go.

But before we tackle the said solutions in detail, it is important that you first understand the possible reasons why your sound stereo is performing in lesser quality than expected. There are many reasons that could cause such problem. As a car owner, it is your job to have the problem identified before we figure out an excellent solution. But hey, most of the time the problems are the solutions themselves and it’s only a matter of choosing car audio equipment like pro’s do. If you don’t seem to confident by this, then feel free to contact an expert to figure out the problem and solution for you. All right. Let’s begin.


Technically, an amplifier prepares the source before it’s release through the loudspeakers. By this, source means the kind of music or sound that you want to hear playing over your car audio system. An amplifier is directly connected to a power supply to which audio signal comes from. It’s task is to take full control of the wirings connected to the speakers. How complicated it is on the inside is the total opposite on how it seems for car owners as it readies itself for operation. With easy-to-navigate options and buttons, sound is easily produced.

A good amplifier must able to balance the input (audio) and the output (produced audio), which means it is well compatible to the speakers. Mediocrity of either one of them would only result to poor sound quality.


High-quality loudspeakers are usually cone-shaped. It is where sound comes out after thorough balancing of audio signals that occur inside the unassuming wirings within an amplifier. Now, most built-in or factory loudspeakers are not as impressive as aftermarket speakers. Give your car audio’s sound more definition and get clearer audio with precise production of bass sounds. Change isn’t something to be fearful about.  If you have special needs in your vehicle, due to space, then check out special categories such as Shallow Mount Subwoofers.


Now, who says you need to focus your attention solely on car audio equipment in which music is directly involved? Give yourself a breather and focus on another angle. You might just realize that your amplifier and speakers are working in their best condition; it’s only that your car’s interior noise is overshadowing your stereos’ music. What do you say about that? Cars, especially the old ones, tend to produce interior noise resulting from loose grips of car parts that resonates through unpleasant vibration sounds. Fortunately, this can be fix through a “damper.” This can be install in some parts of your car to drop unwanted string vibrations.

It is also a great feeling passing your time while stranded in a street jam and at such times listening to some soft heart touching music or some updates of the latest news or the commentary on your favorite game. If you are on a family move to some picnic or party it will be a great entertainer for your family and kids. All that you require is a well-designed stereo system for your car. You can even improve the performance of your car alarms and thus enhance the security of your car. Above all, you can turn on some heads while you are in the parking lot and waiting for someone.

Time that you spend on your car either coming from or going to your workplace or attending meeting or such other business events is not meant for entertainment. It is meant for business. But qualitative car stereo can make your dull timing turn into something real exotic. After all one may not like the dull driving even when going to some important endeavor. Typically a good quality system can include speakers with full range, powered car subwoofers, receiver with blue tooth, and plug-and-play satellite radio that will make your audio experience really excellent.

In fact the car audio system is not merely the combination of a stereo and a pair of speakers. It is much more than that. Multiple components can be added and come into action in making the car stereo system unique and most appealing. It includes satellite radios, amplifiers, various ,types of subwoofers, navigation units, video systems, and the satellite radios. Any or all of them can dramatically transform the features of any traditional car stereo system. Such additions and alterations will not only transform the features of your system but also can change your boring day into something to be highlighted. After all it will be one of the greatest feelings getting your favorite sporting events, news, and multiple other audio streams in your car stereo systems while driving on the highway.
