Caffeine Benefits - Does It Boost Memory?

Caffeine, like chocolate, often receives bad publicity. Whilst in some instances, and in excess, these can have negative effects on our body, they can also be quite beneficial.

I am not disputing that some people are more sensitive to the negative effects of either caffeine or chocolate. For example, excess caffeine can create anxiety, nausea (particularly if taken on an empty stomach), an increase in heart rate, and even depression in some people. And chocolate is certainly not something that should form the mainstay of one's diet. If struggling with sugar addiction, or wanting to lose weight, there are more nutritionally complete foods that are available.

But scientists have turned up some interesting facts on caffeine. For example, caffeine actually blocks the effects of a neurotransmitter in the brain (adenosine) that otherwise makes us feel tired. This is why it works so well to keep us awake. It also encourages the release of another brain chemical, dopamine (as well as adrenaline). Dopamine contributes to a feeling of well being.

Two studies, one a population based study (which are not as specific or rigorously defined as other types of studies, but nonetheless valuable indicators) found that drinking caffeine containing drinks like coffee and tea had a protective effect for those at risk of developing liver disease. Issues that the study participants had that increased their risk of liver disease included alcoholism, hepatitis B or C, obesity, or other complications.

And the results indicated that people who drank more than 2 cups of coffee a day had a 44% lower chance of showing actual liver damage compared to those who drank no caffeine. This was not a clinical trial, and the reason why coffee and tea had such an effect is not known. Coffee and tea contain a range of plant chemicals (phytonutrients) that could be responsible for this. A 2005 Norwegian study also found similar benefits for coffee with regards liver disease. This study found that drinking 3 cups of coffee a day could lower the risk of death from liver cirrhosis.

Even if you're not at risk of liver disease, caffeine still has some advantages. Recent research from Austria showed that caffeine may actually enhance short term memory. Researchers found that there was an increase in brain activity (as measured by functional magnetic resonance imaging) in the parts of the brain that were associated with memory and attention. These parts of the brain were the frontal lobe and the anterior cingulum. This was a placebo controlled study, meaning that some people were not given any caffeine. Another, earlier study (2004) found that caffeine did support short term memory, but only when it was in relation to a topic that people were already thinking about. This study found that when testing coffee's effects on unrelated subjects, short term recall was actually inhibited.

Everything does have a flip side though. Adenosine, which is blocked by coffee, is also calming. This could be why it can also cause anxiety in excess, and in some individuals. After all, the balance of our brain chemistry is unique. And when we are addicted to stimulants like caffeine, we lose the sensitivity to our own natural stimulants (dopamine and adrenaline).

The Best Picks For Home Coffee Makers

Coffee in the morning. Coffee at the office. Coffee in the afternoon or after dinner. Coffee consumption is a ritual of enormous proportion and that has feed the need for the ever faster and more efficient way to make the coffee.

Coffee makers have evolved like everything else in the world of technology. A simple filter over a pot of steamy water is ancient history. The coffee makers we find today do it all and do it better than ever before.

How Do You Take Your Coffee?

There are so many new kinds of coffees and ways to take it that you almost need an English to Coffee dictionary to interpret for you at the coffee shop. Even more revealing is the fact that many people want to have these exotic mixes and brews in their own homes to enjoy any time of day or night.

Home coffee makers don’t just make regular coffee. There are Espresso Maker machine and Cappuccino Makers that make what one could only find at a nice restaurant a decade or two ago. Now these machines at home can grind fresh beans into the perfect recipe and dispense the perfect cup.

The Machines Behind the Madness

Coffee makers are machines of fine craftsmanship and technological wonders all blended into one. The build-in grinder for example, allows you to have a freshly ground cup that is strong and flavourful without having to grind it at the grocery store or specialty shop. Each cup has its own freshly ground beans. Bunn is one such manufacturer of the combination coffee maker.

The espresso machine or cappuccino maker can add milk at just the right time and temperature so the art of making it yourself is easy to master. (Your guests need never know you didn’t figure it out on your own.)

Today’s kitchen is rendered almost obsolete if it doesn’t contain one of the latest coffee makers. The single cup coffee maker is a growing trend as people are trying to cut down on the caffeine. The single cup maker is also ideal if there is only one coffee drinker in the house or if you usually take your coffee at the office.

Let’s Talk Beans

Part of what makes a great cup of coffee is the beans. The other part is how well the coffee maker can accurately blend that perfect balance between water and coffee grounds. Most of the world’s coffee is grown in a belt consisting of a latitude around central America and around the globe through Africa and Asia. It is this climate that gives the beans the right conditions and perfect growing season so beans can be naturally brought to ripeness.

The next step is the roasting of the beans. The methods vary, but the goal is the same. The idea is to roast the beans to the point they are the most flavourful and aromatic.

Of all the drinks to come and go, coffee remains internationally neutral and has proven a staple of homes world wide for generations. The only difference is in how simply and skilfully it is made. The coffee makers behind the beans have taken coffee making to an art form.

Tips For Buying A Great Espresso Maker

Most people who love specialty coffee drinks eventually purchase an espresso maker. With a good one, you can make all your favourite drinks in the comfort of your own kitchen and try out a new recipe or two. Since this is a large investment, you should spend some time learning about these machines before you buy. Learn about the features available and then read some reviews to find the best machine for your home.

Common Types of Espresso Maker

Manual Espresso Makers
Manual machines require you to do all the work. You measure and grind the beans, tamp the grounds and brew the coffee. These are the least expensive machines. Some avid espresso drinkers will only use a manual machine.

Semi Automatic Machines
Semi automatics do some of the work for you. You adjust the water temperature and pressure. Grind and tamp the beans and the machine will do the rest. They are more expensive than a manual machine, but much more affordable than a fully automatic model. These machines are a good first cappuccino maker.

Automatic Machines
Automatic machines do the whole job for you. All you need to do is add the water and the beans. With the touch of one button, you will have a great cup of your favourite java drink.

Super Automatic Machines
Super automatics do everything from grinding and tamping the beans to the finished product. They pre infuse the beans with water for more flavour than other machines. The entire process is faster than regular automatics. These machines are often found in restaurants and coffee bars.

Great Espresso Maker Features
The features vary from machine to machine. When comparing two models, look at the features included with each to determine which will suit your needs better.

Bean Grinder
More expensive machines often have a built in grinder. The beans are ground for each individual cup. This results in more flavour from the oils inside the beans. The drink will taste fresh with this feature.

Milk Frother
For cappuccino or latte drinks, you will need a frother. This can either be a frothing wand or a separate milk container. More expensive models have a container.

Pod Compatible
Pods are small packets that consist of a filter material on the outside and ground beans on the inside. The pods are pre measured for one cup. Just put the pod in the machine and brew your coffee. Most people either love the pods for the convenience or hate them and lament the bitter taste.

Water Filter
Some of the more expensive machines have a built in water filter to remove chlorine or other chemicals from the water prior to brewing. These are mostly carbon filters. If your water is heavily chlorinated, you will notice the difference with a built in filter.

Cup Warmer
A cup warmer keeps the cup warm before brewing. This results in a hotter drink. This feature is usually located on the top of the machine.

Hot Water Dispenser
Some machines have a separate valve for dispensing hot water. This feature is great for making tea or hot chocolate. Most machines used in commercial establishments have this feature.

Some Other Things to Consider

o Steel or brass machines are best. Some people detect an aftertaste with aluminium machines.
o Look at the pump pressure on home coffee makers. More powerful pumps work will with finer grounds. You should have a minimum of 14 bars or more for pump pressure.
o Look for a removable water tank. This is easier for cleaning or emptying and will prevent stagnant water from collecting at the bottom of the tank.

The Coffee Bean

Coffee is a beverage, served hot or with ice, with or without cream and sugar, prepared from the roasted seeds of the coffee plant. These seeds are almost always called the coffee bean. Coffee is one of the most popular beverages in adults today.

The coffee bean, itself, contains chemicals which are mind-altering (in a way some find pleasing) to humans as a coincidental result of their defense mechanism; those chemicals are toxic in large doses, or even in their normal amount when consumed by many creatures which may otherwise have threatened the coffee beans in the wild.

A coffee bean from two different places usually have distinctive characteristics such as flavor (flavor criteria includes terms such as "citrus-like" or "earthy"), caffeine content, body or mouthfeel, and acidity. These are dependent on the local environment where the coffee plants are grown, their method of process, and the genetic subspecies or varietal.

Some well-known arabica coffee beans include:

* Colombian - Coffee was first introduced to the country of Colombia in the early 1800's. Today Maragogype, Caturra, Typica and Bourbon cultivars are grown. When Colombian coffee is freshly roasted it has a bright acidity, is heavy in body and is intensely aromatic. Colombia produces about 12% of the coffee in the world, second only to Brazil.

* Colombian Milds - Includes coffees from Colombia, Kenya, and Tanzania, all of which are washed arabicas.

* Costa Rican Tarrazu - from the Tarrazu Valley in the highlands outside of San José, archetypal estate coffee is La Minita.

* Guatemala Huehuetenango - Grown at over 5000 feet in the northern region, one of the most remote growing regions in Guatemala

* Ethiopian Harrar — from the region of Harar, Ethiopia

* Ethiopian Yirgacheffe — from the area of the town of Yirga Cheffe in the Sidamo (now Oromia) region of Ethiopia

* Hawaiian Kona — grown on the slopes of Hualalai in the Kona District on the Big Island of Hawaii.

* Jamaican Blue Mountain — From the Blue Mountain region of Jamaica. Due to its popularity, it fetches a high price in the market.

* Java — from the island of Java, in Indonesia. This coffee was once so widely traded that "java" became a slang term for coffee

... and more.

Some coffee bean varieties are so well-known and so in-demand that they are far more expensive than others. Jamaican Blue Mountain and Hawaiian Kona coffees are perhaps the most prominent examples. Often these coffee beans are blended with other, less expensive coffee beans and the suffix "blend" added to the labelling, such as "Blue Mountain blend" or "Kona blend" even though they only contain a small amount of the coffee bean mentioned.

One unusual and very expensive variety of robusta is the Indonesian Kopi Luwak and the Philippine Kape Alamid. The coffee bean is collected from the droppings of the Common Palm Civet, whose digestive processes give it a distinctive flavor.

How To Select A Coffee Roaster

If you have decided to roast your own coffee then your first port of call will be to consider how to select a coffee roaster that is right for you. This decision is probably one of the hardest coffee-related choices you’ll have to make – there’s nothing worse than buying the wrong kind of roaster for your needs.

We’re going to be primarily looking at automated custom coffee bean roasters for the purposes of this article. But, it’s worth noting that you can roast your own coffee beans fresh at home without having to buy a roasting machine.

It is possible to roast beans in or on the stove, on a barbeque or fire or even, sometimes, in a popcorn popper. But, if you take your home roasting seriously and want some help with the process (the do it yourself approach can take a lot more time and effort) then a proper roasting machine may be your best option.

So, why do people roast their own beans at home? Well, it’s basically all about freshness and the quality of the roast you will ultimately get. If you buy green coffee beans – i.e. beans that are unroasted – you can simply roast them at home when you need to use them in batches so they’ll be ultra fresh. Green coffee beans are cheaper and last longer than ready roasted beans into the bargain. By the way, more information on bean roasting can be found here: http://www.coffee-n-beans.com/roasters.html

The ability to roast your own beans is a desirable must with many coffee aficionados – you can do away with stale coffee, get the level of roast you want when and where you want it and save yourself some money into the bargain!

In very simple terms there are two main types of machine to consider when you’re deciding how to select a coffee roaster which are Fluid Bed/Air Roasters and Drum Roasters.


Fluid Bed/Air Roasters

If you want to roast your own coffee beans at home then the first thing you should look at is getting hold of a standard fluid bed based roaster. These machines are small, can be compact and are primarily designed for small-medium home use. So, they will roast your beans for you fairly quickly and with minimal fuss – you don’t have to stand over them for example, as you would if you were home roasting on the stove top.

These kinds of roasters kind of work like popcorn makers in that they use hot air during the roast process. You can see how the roast is progressing in most cases so you can control it more effectively and you will sometimes also be given pre-set roasts to choose from in any case. If you’re a home roasting ‘newbie’ then this kind of machine may suit you best as you will get a feel for the whole process as you go along – you can always upgrade to a bigger and more complex roaster at a later date when you have more experience. These machines are also cheaper than other options and are relatively easy to use in the kitchen.

There are a couple of downsides with this kind of roaster, however. You will find that some models won’t roast that much coffee at once and will burn out if you use them too often. Some models also don’t have such great controls or pre-sets (some don’t have any) – so it may take a while for you to get used to using the machine if this is the case.


Drum Roaster

If the option of a fluid bed roaster doesn’t seem quite right to you when you’re thinking about how to select a coffee roaster then you could also look at drum roasting as an alternative. Drum roasters were once only seen in coffee shops and stores that roasted their own coffee beans but, nowadays, it’s real easy to buy machines for domestic use.

Drum roasting machines can basically roast more beans at once – in most cases – than fluid bed machines as they are bigger. Most will work on a convection or conduction method. With this kind of machine you place your beans in a drum, close it up, set it running and wait until the roast is done.

This is more of a pro machine – although they are designed for use at home – simply because they can be more complex to operate than fluid bed roasters. But, the majority of true coffee fans will prefer this method over time as it is held to produce better results in coffee taste terms.

The downsides with many drum roasters is that they don’t have a window so you can’t always look inside them as you can with most fluid bed roasters. So, you may have to rely on your sense of smell or hearing (as you listen to the coffee bean cracks!) to work out when your roast is perfectly done. This is one of the reasons why these machines may not suit ‘newbie’ roasters to start off with.

Some of these drum machines can also give off a lot of smoke so you may need to sort out adequate ventilation or even do your roasting outside if this is the case. And, as you might expect you’ll pay more for drum roasters than for fluid bed machines. At the end of the day you’ll need to think long and hard about how confident you are with the home roasting process – if you haven’t roasted at home before then you may be better off starting off with a fluid bed machine but if you feel more confident and need the extra functionality then a drum roaster may suit you better.

Whichever type of machine you choose to buy do remember that it’s absolutely vital to read some user reviews on the Internet before you buy a roaster as these will tell you stuff the manufacturer won’t. These reviews are written by people who have used these machines and they will give you a real good idea of the pros and cons of any machine from people that have used them regularly.

Some example tips to look out with for fluid bed roasters include:

- How well do the programs (if there are any) work?
- How easy is it to use and what kind of functions does it have?
- How well made is the roaster?
- How evenly does it roast?
- How well can you see into the roasting chamber?
- How noisy is the machine?
- How easy is it to clean the machine/parts?
- What happens to the chaff?

Some example tips to look out with for drum roasters include:

- How well do the programs (if there are any) work?
- How easy is it to use and what kind of functions does it have?
- Does it produce a lot of smoke?
- Can you see inside the drum from the outside?
- Does the machine get too hot?
- What happens to the chaff?
- How easy is it to clean the machine/parts?

Brewing A Perfect Cup Of Coffee

Brewing a great cup of coffee depends on a number of things such as the quality of the coffee bean, the quality of the water being used, the type of brewing being done, and the grind of the coffee. Now quality of bean and water is something you can easily take care. Just use good quality beans and pure water. However the relationship between the grind of the coffee and the type of brewing being done is more detailed and could use a little explanation. Now we all know that we make coffee by passing hot water over crushed coffee beans. However for it to really work well we need to understand just how long the water should be passing over the beans. The purpose of this article is to help you understand how to match your coffee's grind to the type of brewing you are doing in order to make the best coffee possible.

Generally speaking, the 'soaking' time relates directly to how coarse the coffee is ground. This means that smaller coffee grinds need less contact with the water, and coarser grinds need longer contact. Espresso coffee is only exposed to water for 20-40 seconds and as a result is made using extremely fine grind coffee. A French press coffee maker can take as much as 4 minutes and uses an extremely coarse grind. If coffee is left contacting water for too long for its grind size, unwanted extracts emerge and make the coffee taste bitter. Of course if the grind is too large and the water passes very quickly (like using frech press grind in an espresso maker), very little of the caffeine and flavours extracted and will have poor flavour.

Of course filters play an important role in managing the balance between over and under brewing your coffee. Not only do they keep the grind out of your cup, but they also control how fast the water passes over the grinds. Paper filters are the most common, but many people are also using metal varieties. Paper filters are quite good. However they can absorb some of the coffee flavour, and some people claim they can taste the paper in the final coffee. Metal filters are normally made from stainless steel or gold plated mesh. They have very fine weave and filter out the coffee grinds very well. They also do not alter the taste of the coffee at all. Metal filters are also more environmentally friendly than the paper alternative.

Whichever you choose, be sure to buy decent quality. Cheap filters often clog or not allow the coffee to brew properly. A decent quality metal filter will last years and save money in the end.

Brewing a cup of coffee is not that hard. Brewing a great cup takes a little more understanding, but isn't any harder. Start with fresh beans and good clean water and then match your brewing style to the proper grind and then mess around with the exact proportions and pretty soon your be brewing killer coffee every time.
