1st Wave of Coffee
The first wave of Coffee dates back to the 1800s when this beverage consumption started to grow exponentially, brands such as Folgers and Maxwell House are an example of the forerunners of this wave. Quality was not important as price in this wave. A great innovation in this wave was the Vacuum packing which took the air out of the coffee tins to maintain the freshness of the beans. There was zero knowledge about the origins of the coffee or processes.
The focal point of this wave was to make coffee a widely consumed product, to become a mass market product which could be found in every household. An innovation which marked this first wave was the invention of instant or soluble coffee which made the preparation of coffee a fast and convenient way to make this beverage.
2nd Wave of Coffee
The second wave of Coffee started in the 1970s especially with the birth of the now coffee giant Starbucks which understood that people needed to see coffee as a whole experience rather than just as a beverage. Customers started expressing the desire to know more about the origins of their coffees and the unique roasting styles, thus bringing the start of the specialty coffee era.
The most important characteristic of this wave, is that the coffee experience evolved from just a quick caffeine fix to a point of encounter, thus making coffee shops a point where people went to have social interactions and giving coffee a special place in the social dynamic.
3rd Wave of Coffee
The third wave of Coffee as a term was first used by Trish Rothgeb back in 2002 published in the Roasters Guild Publication defining the three Coffee movements as “waves”. This wave is characterized by a market made up of much more sophisticated coffee consumers, that are interested in having an exceptional cup of coffee rather than just a cup of who-knows-where this came coffee from?
An important feature of this wave is that of the Specialty Coffee which was a turning point on the coffee industry. The quality of the coffee became very important, and with it, a lot of other aspects of the coffee such as the formation and professionality of the barista, the traceability of the coffee beans, micro roasters and fair-trade coffee just to mention a few.
“The third wave is, in many ways, a reaction. It is just as much a reply to bad coffee as it is a movement toward good coffee.” – Trish R. Skeie

Coffea Arabica or just Arabica is also known as the Arabian Coffee. This is one of the two main species of Coffee, it is regarded as the one with a rich and complex organoleptic profile and better quality, no wonder why it represents approximately the 60% of the worlds coffee production. Arabica is grown all over the world, in regions such as Africa, Latin America, and Southeast Asia. It is thought to be the first type of Coffee to be cultivated in the world.

It is expressed as the ratio of ground coffee mass to water mass used during extraction. It can be expressed with the European standard which is g/l(grams per liter/ e.g. 60g/l for pour-over coffee) or with the American standard 1:x(e.g. 1:16 it’s the same as 60g/l)
One of the most important parameters during the extraction phase is the water temperature. It substantially affects the organoleptic characteristics of the coffee cup. Usually, temperatures between 92 ° C and 98 ° C are preferred: low temperatures emphasize the acidity and the fruity scents, while higher temperatures mostly extract the chocolatey and toasted notes up to the bitter. It is possible to precisely control the water temperature by using electric boilers with temperature setting or special thermometers for traditional boilers.
It refers to the period of time in which the water comes in contact with the ground coffee, this is when the extraction happens.
There is an optimal brewing time for every method, check out our brewing guides for more details.

Main natural alkaloid present in coffee, responsible for the stimulating and psychoactive effect of this drink. From a sensorial point of view, it gives bitter notes to coffee, which is why the Robusta, which contains more caffeine than Arabica, is characterized by a more marked bitterness. The amount of caffeine contained in the coffee beans varies according to the cultivar, however, the content of this alkaloid extracted in the drink depends substantially on the extraction method and on the contact time between coffee and water.

Also known as “World’s most expensive Coffee” is a type of Coffee made with the help of a little cat-like animal named Asian palm civet (Paradoxurus Hermaphroditus) native to southeast Asia. Coffee cherries are eaten and then excreting the partially digested beans, and theoretically, it makes the flavor of the coffee even better. Given the difficulty of finding the civet droppings in the wild, and having to collect them by hand the price is inflated so much that it has been renamed as the most expensive coffee. The problem with this coffee is that because of its high demand, some farmers started caging the animals and feeding them only coffee cherries thus restricting their diet and making them suffer in the process, that’s why many activists have called out companies that sell that coffee and asking the public to not consume this product.

The process of heating the beans to be able to extract the great flavors of the bean. During the roasting process, the coffee beans tend to lose most of their humidity they then start getting brownish and depending on the roasting time the darker they will get. This process is vital to the development of the flavors that will then be extracted on a cup.
The roast date is used to keep an eye on the freshness of the beans, a rule of thumb is that roasted coffee lasts fresh for about 2-3 months, depending on the type of roast and the way it is stored, but if you want to be more precise you should ask your roaster directly how long it stays fresh.
Roasting degree refers to how light or dark is the bean after the roasting process, there are many types of roasting such as first crack, city roast, full city, second crack, Vienna, French roast, charcoal, etc..
A roast profile represents the effects of how the airflow and the heat are controlled during the roasting which determines how quickly the beans arrive at a roasting degree.
The second of the two main species of coffee, its scientific name is Coffea Canephora and it is characterized by having a smaller and rounder bean. Its organoleptic profile is less rich and complex compared to that of the Arabica. Usually, it is used in mixes intended for espresso because it gives a strong bitter note and a more consistent crema.

Seasonal coffee is different from commercial coffee because commercial coffee has such great volumes that it can be available all year long.
Semi-washed honey process
This style of processing the coffee which is a mix of the dry processing and the washed
These terms often refer to the same style of processing, where the first stages of the above are followed up until the cherries are pulped. Then, instead of fermenting the coffee in tanks, it is sent to be dried while the mucilage is still intact and stuck to the seeds. As the seeds dry, the mucilage loses a good deal of moisture but can contribute a greater degree of sweetness to the seeds (perhaps because less fermentation is taking place, meaning fewer sugars are being consumed by microorganisms). Once dried, the seeds may be washed to remove the stuck on pulp, or simply proceed to de-hulling. The green coffee seeds may also be dried again to reach the desired moisture content, as drying coffee in this state can take longer than the washed process. This process can also introduce complications that lead to flavor degradation, including mold growth, rot, and pests which are attracted to the sweet-tasting mucilage as it dries in the open air. These coffees must be carefully attended to during drying to properly maintain their flavor.
A type of coffee which is not a blend, to be considered single origin it has to come from only one producing country, sometimes from a specific region or plantation
A coffeemaker that utilizes vacuum pressure and a series of containers for brewing the coffee.

A harvesting method which consists in stripping all the coffee cherries in a branch, usually also the leaves. In this way, the harvest is not homogeneous because alongside the mature cherries there will also be unripe and over mature cherries. This method is usually used for massive plantations with low quality. Strip picking can be done by hand or with mechanical devices made for this purpose.
A device that is used to press the ground coffee into the coffee basket to prepare it for extraction.
Terroir is a French expression that comes from terre “earth”, it means a well-defined area and the set of all the environmental characteristics that affect a crop or a product. It is also used in other industries such as wine, agave, tomatoes, chocolate, maple syrup, and cannabis. It includes conditions such as type of soil, average temperature, elevation, atmospheric pressure, annual rainfall, amount of sunlight, etc…
