How many coffee cups can be made from 1kg of coffee beans?
One coffee portion is usually made from 8 to 12 g of coffee, so taking the average, from 1 kg approximately 100 cups of coffee can be made. This calculation can differ according to the chosen coffee strength, i.e. grounded coffee amount.
Does the roasting affect the coffee taste?
When choosing coffee we recommend to pay attention to the roast levels. This bean processing step is very important and can either reveal and balance the flavors or ruin them. Choose lightly roasted coffee if you want to try the real taste from nature. Usually, light roasts are made from high quality beans, for the purpose of highlighting and bringing out its all finest qualities. Medium roasts are very popular in blends, when the goal is to balance the taste of different types or beans that are grown in different regions. Dark roasting can result in a dark color and chocolaty bitterness, that is why it is especially suitable for italian, belgian, french type coffee blends. Though, dark roasts should not be mistaken with burnt coffee beans. Very oily and pungent coffee beans have nothing in common with high quality dark roasts. This type of product can be found at a very low price, however their taste will not be as pleasant.
How does the coffee origin impact coffee?
It is important to mention that the best conditions for growing coffee are near the equator, that is why the number of countries where you can find coffee plantations - is very limited. This area is called the “Coffee Belt”. However, due to the soil and climate peculiarities, local farmers tend to choose the most yield giving plant varieties (there are about 150 Arabica types in the world, Robusta - about 50). Due to this reason, coffee in each region is very different. For instance, coffee originated from different American regions tends to have a fairly universal taste. The majority of them have little sourness (fruitiness), the dominant flavors are nutty, it is possible to feel slight bitterness, flower aromas. It is also important to mention that the majority of the whole world coffee is grown in Brazil, that is why the coffee from there is considered to be a classic taste standard. Coffee that is grown in African regions is more fruity, its flavor can have a softer or stronger acidity. This coffee is medium intensity and is especially liked by coffee experts. The richest flavored coffee of this region is often from Ethiopia, so to get acquainted with this region's flavors choose coffee from this country. Meanwhile the coffee that is grown in Asia is usually the “heaviest”. When this coffee is made it has a dark, intense color, and the aftertaste can be felt for a long time. Dominant notes - chocolate, spices, and can even have soil or wood aromas. For example, coffee grown in Sumatra region due to its region of origin, as well as special local processing has almost no acidity. Brown sugar, cinnamon and caramel can be felt in this type of coffee. If you prefer a classic coffee taste - coffee grown in Sumatra can become your starting point in the journey of getting acquainted with quality coffee.
How to identify high quality coffee?
The highest quality coffee is usually lightly roasted. Consequently, its color tones will always be light brown. High quality beans will be in a classical form, healthy, without any significant damages. The aroma will always be pleasant and resemble natural, in nature existing scents - flowers, fruits, wood, soil. Whereas low quality beans are oily, can have dampness, mold scent. Burnt beans are also identified as a low quality coffee. They have a pungent taste not only after opening the package, but also after making the coffee. Only in low quality coffee bitterness and unpleasant sourness can be felt at the same time. This, during processing developed sourness, has nothing to do with the fruity lime, raspberry, cranberry or other fruits and berries sourness.
What makes specialty coffee beans exceptional?
Coffee beans that are certified by the American coffee association are called Specialty coffee. This document is granted for those coffee bean producers that ensure high-quality coffee bean growth, crop harvesting, processing, and in the end result in well-balanced flavors and aromas. This type of coffee beans will always have the proper shape, will be dry (not oily), fragrant. This coffee category includes only the coffee that has a score of more than 80 points. For example, “Ethiopia Burtukaana” is evaluated by 88 points, and “Kenya Kariru“ – 87,5. Specialty coffee can also be a limited edition, in special conditions grown, collected, and processed coffee. One of these types of coffee “Kivu” is unique in a way that it is grown only near Kivu lake, in the democratic republic of the Congo. Another coffee that stands out with its extraordinary growing location is called “Blue mountain”. Its coffee bean bushes grow in a mountainous area, that is why their crop harvesting is extremely difficult. Moreover, the “blue” mountain status is only given to the coffee that grows 910 m and higher above sea level. Growing in these conditions, this coffee stands out with its exceptional taste and is highly appreciated by the coffee enthusiasts. Because of its unique way of processing the coffee beans, “Kopi Luwak“ is considered to be one of the most expensive coffee in the world. This coffee cares more about fair and animal abuse free trade certificates, than any other quality validations. Thus, even without the highest evaluation, “Kopi Luwak” is referred to as a specialty, limited edition coffee.
What is Arabica and Robusta?
Both Arabica and Robusta are coffee bean types. Arabica coffee beans tend to have a more intensive flavor, fruitiness, and have a naturally sweet taste. Whereas Robusta coffee beans are more bitter and have up to 2 times more caffeine. Due to high caffeine levels, harmful pests tend to avoid damaging Robusta beans, thus it is easier to grow them. Arabica coffee is particularly popular. However, now more often than before Robusta is being added to coffee bean blends. If properly balanced, these two coffee bean types can create a great coffee, filled with roasted caramel or black chocolate bitterness flavor, dark color, and a beverage that goes especially well with milk.
How to choose coffee beans?
To find your favorite coffee, you should ask yourself this question - which coffee do I find to be the tastiest? Do you prefer light, but fruity sourness or strong, maybe a bit bitter taste? Or maybe you prefer just a good and simple cup of black coffee? Or will you drink it with milk? It is important to mention, that coffee flavor is influenced by a couple of factors:
- COFFEE BEANS TYPE: Arabica is softer, a bit sweeter, more fragrant. Whereas blends with Robusta are more bitter, harsher, and have more caffeine in it.
- COUNTRY OF ORIGIN: Depending on the country of origin, dominant flavors and aromas can differ in coffee.
- ROASTING: Light roasts help to preserve the natural coffee flavor - soft fruitiness, fragrance, and light brown coffee bean tones. The higher the coffee bean roasting level gets, the darker, stronger, and more bitter the coffee flavor gets.
What is Cold Brew Coffee?
Cold brew - cold brewed coffee. The ground coffee is prepared by pouring cold water and leaving it to mature for several hours. It can be prepared by yourself without the use of any devices: we pour coarsely ground quality coffee with cold water (in the ratio 1: 5, and if we want to prepare the dilutable concentrate - in the ratio 1: 2). We leave for several hours to mature in a cool place. After that we knock out the thick and we can enjoy it for even a few weeks. If we don’t want to “play with the thicken,” we can purchase a special Cold Brew coffee tool.
Cold brew coffee is especially popular during the warm season because it is extremely fresh, tonic (high in caffeine) and sweet. It is especially tasty to drink just like that, seasoned with ice cream. Cold brew concentrate is also used to flavor desserts.
Caffeine: What kind of coffee does have the most of it?
Most caffeine is found in robust coffee beans - twice as much as in arabica beans. Therefore, a blend that includes robusta, or 100% robusta coffee, or instant coffee (which is mostly made from robusta) will have more caffeine than 100% arabica coffee.
The amount of caffeine also depends on the method of coffee preparation. Caffeine is soluble in water, so the longer the coffee to water ratio, the more caffeine there will be in the coffee. So comparing a small cup of espresso to a cup of coffee in which water was simply poured on ground coffee, the adviser will have more caffeine. Although in the sense of taste it may turn out the other way around.
Which coffee beans are best suited for automatic coffee machines?
All coffee beans, except flavored ones, are suitable for use in automatic coffee machines because they damage the mill itself. And then it all just depends on individual taste. Just keep in mind that lighter roasted beans, which are more designed for filter coffee preparation, can be much higher quality when prepared through an automatic espresso machine. However, it would be better to choose medium or dark roasted coffee beans to make the taste more pleasant. Some coffee makers even state on the package that the coffee is roasted specifically for espresso coffee machines or automatic coffee machines.
What are the main types of coffee?
There are many types of coffee, but the most common and popular are these three: Arabica, Robusta and Liberica.
Arabica coffee trees are much more difficult to grow than Robusta or Liberica. They are particularly sensitive to cold, temperature differences, they need shade and higher altitudes. However, the palette of flavours that develop in ripening Arabica coffee berries is the richest. There are numerous of Arabica subspecies and they all have their own special taste characteristics. Dominated by sweet and sour, fruity berry notes.
Robusta coffee trees are not as delicate as Arabica. They are much more resistant to climatic conditions and pests. Therefore, they are much cheaper and easier to grow. The palette of flavours is narrower. Robusta has twice as much caffeine as Arabica. Mostly used in coffee blends and less often on its own. Robusta provides thickness in body, stronger caffeine kick and bitterness to the coffee blend. Dominated by bitter, intense flavour notes.
Liberica is the least popular of these three species because it does not have such flavour characteristics as Arabica or Robusta. Liberica is used to make instant coffee.
How to distinguish Arabica, Robusta and Liberica?
Arabica, Robusta and Liberica beans can also be distinguished visually. Arabica beans are oblong in shape and have a wavy stripe in the middle. Robusta beans are round in shape, smaller, the strip in the middle is straight. Liberica beans are much larger than Arabica or Robusta.
