Numerous ill-understood chemical reactions occur during the development phase, and the length of this phase in concert with a coffee’s finish temperature (the temperature at which it drops from the roaster and into the cooling tray) is what determines a coffee’s level of acidity and sweetness. Post was not sent - check your email addresses! Now that we’ve discussed green coffee analytics and roasting technique, I will apply this information to an example coffee to illustrate how I might approach profiling a new coffee for production. Washing coffee is a prevalent processing method because it tends to produce coffees which are very clean and free of off-flavors, which is a result of the use of water to clean the coffee seeds. In the complex international coffee trade, beans are bought and sold as commodities and specialty products, through direct sales or via several layers of middlemen. Cafe Altura Organic Coffee Cafe Altura, the first organic coffee company in the United States, was created to share organic beans sourced from farms around the world with coffee lovers everywhere. Washed Process On this edition of the blog we’re going to discuss the coffee world’s major processing methods, the ways in which these methods differ from one another, and the way processing exercises influence on the flavors you taste in your cup. Like a washed coffee, honey processed coffee is pulped, but like a natural coffee, no water is added, and the coffee is dried with the skin removed, but some of the mucilage remaining. Coffees produced using the washed method tend to have great flavor clarity and express a wide array of flavor profiles because of this; optimally, washing coffee yields the truest expression of that coffee’s inherent flavor characteristics. Caramelization phase is the middle phase of the roasting process, during which sugars inside of the coffee bean begin to caramelize rapidly. Here’s a look at 5 reasons why coffee should work its way into your diet. $27.40. Want to add a belated word here about the integrity of Cafe Altura. Washing coffee begins by running freshly picked coffee cherries through a pulper, a machine which removes the skin of the fruit and exposes the coffee seeds (called parchment at this stage) underneath. The same is true of a small bean coffee over a large-bean coffee; a smaller surface area changes temperature more rapidly than a larger surface area, despite the larger surface area’s greater thermal conductivity. There is more to roast profiling than green coffee, however; understanding the way in which a coffee roasting machine operates and the different ways in which they change coffee beans as they heat them is also irreducibly crucial to coffee roasting success. The standard coffee processing method in Indonesia, wet hulling starts off like washed processing; First coffee is pulped, then fermented. Effective coffee roasting requires constant learning and iteration, and even when you’ve done it for a while, new coffees can always throw you a curveball. Honey Process This is my second bag of Colombian Whole Bean Organic Coffee by Cafe Altura. Save my name, email, and website in this browser for the next time I comment. The fact that this coffee is only grown in Chiapas makes it somewhat a single origin coffee. Peaberry beans, around 5-10% of coffee beans, represents one such niche. Shorter development phases and lower drop temperatures tend to produce coffees which are high in acidity and sweetness, whereas longer development phases tend to produce coffees which are low in acidity and possess more caramelized flavor profiles. Article By : Bret Colman, Director of Coffee / Head Roaster, Cafe Altura Organic Coffee If the coffee is not constantly turned while it is drying, it will ferment and produce off flavors. The most salient properties are bean density and bean size. While we often discourage such adding too many flavors that distract from the coffee itself, we aren’t above making exceptions. Peaberry beans, around 5-10% of coffee beans, represents one such niche. Natural processed coffee is a simple method which requires little machinery, and its lack of water means that it is popular in countries like Brazil which have a dry climate and constrained water resources. This article has detailed a few of the major methods of processing coffee, and hopefully shed some light on why your morning cup tastes the way it does. We roast only the highest quality beans, which deliver a rich, flavorful cup of coffee with a seductive aroma and smooth finish. In earlier posts on this blog, I spent some time describing the factors we consider when we purchase green coffee at Café Altura, as well as the phases of the roasting process and how their manipulation can affect a coffee’s flavor. As a hybrid process, honey processing faces some of the difficulties of both washed processing coffee (higher equipment costs) and naturally processed coffee (need for meticulous drying practices), but overall represents an exciting new chapter in the coffee industry with lots of potential for tasty coffee. After fermentation, however, the processes diverge; instead of being floated and washed, the coffee is stripped of all its protective coating and then dried. This would mean a high initial temperature and heat setting, as well as aggressive application of heat throughout the roast. Coffee and its health benefit have been well-documented, on this site and beyond. Exceptions to these rules abound, of course, but this is what makes roast profiling so compelling; it is an inexact science which requires relentless experimentation to achieve success. These same properties considered in purchasing can also be helpful clues when I begin to contemplate a coffee’s roast profile. This in turn allows farmers to get the highest possible price for their crop, as the coffee market tends to favor clean and flavorful washed coffees over other processing methods. In situations like this, i.e., when a coffee has primarily low toned flavors but retains some acidity, I tend to keep development static and modulate acidity through changing the coffee’s finish temperature. Drying phase thus affects a coffee’s flavor profile indirectly, and as such modulation of the drying phase is used as a profiling technique primarily as a means of setting up the later phases of the roast to occur in a desired timescale. As the industry has grown, so too have its by-products and repurposed defects grown into industries of their own. Vary levels of mucilage removal leads to different levels of honey processing, which range from black honey (a lot of mucilage left on the beans) to white honey (very little mucilage left on the bean). The most common means of processing coffee throughout the world is known washed or wet processing. This means that a high density, small bean coffee will take on heat very fast and roast very quickly, whereas a coffee with low density and a large bean size will roast more slowly. This causes the acidity to be present while preventing it from predominating, allowing the coffee’s primary low-toned sweet notes to take center stage. Follow these steps and you’ll fast become an office favorite. As described in my previous post on green coffee analytics, understanding the physical and sensory properties of a given green coffee is a crucial step in the purchasing process. We offer a wide variety of coffee processed in these different methods over the course of the year, so be sure to keep an eye out and sample some new processes. Today, I’m going to talk about how we combine these elements in our roast profiling, or how Café Altura determines roasting and flavor specification in coffee production. Sign up for our world class barista training and learn from the very best. Fermentation is followed by floating the coffee in channels to remove defective beans; low density coffee, which tends to be lower in quality, rises to the top of the channels where it can be collected and disposed of, while higher quality, high density coffee remains at the bottom of the channel. Allergy Relief , 24 Hour Allergy Relief , Loratadine 10mg Tab , 100 Tab 4.7 out of 5 stars 1,084. Coffee cooperatives are one of the most influential parts of the global coffee trade and one way that growers try to have their voices heard within the …, Why Cans are the Best Packaging for Coffee. Drying phase, the first stage of the roasting process, does not directly impact a coffee’s flavor profile, but rather, sets the momentum for the entire roast, which sets up the phases which succeed it. The coffee is then washed by repeatedly moving it back and forth in the water channels, with the goal being to remove the mucilage loosened by fermentation. Save my name, email, and website in this browser for the next time I comment. Additionally, the coffee has mild, but present acidity, which means that development can’t be too long, nor finish temperature too hot. A long caramelization phase generally dictates that a coffee will have heavier body, low sweetness and potentially low acidity, whereas a short caramelization phase generally means that a coffee has lighter body, high sweetness, and potentially high acidity. As the industry has grown, so too have its by-products and repurposed defects grown into industries of their own. It’s a number which continues to increase, along with demand for beans. People can have a love/hate relationship with office coffee. I tried others like their Sumatra and Peruvian but have come back to this. The coffee’s sensory characteristics aid me in making that general outline a little more specific. The dry husk surrounding the coffee is then removed, and the coffee is bagged and prepared for export. Read our blog! Article By : Bret Colman, Director of Coffee / Head Roaster, Cafe Altura Organic Coffee, Your email address will not be published. Knowing how these properties of a given coffee bean combine and equate to behavior in the roaster is an important step in determining the optimal profile for a coffee. As long as there has been good coffee there have been people trying to put new things in it. The same goes for sorting the cherries after drying; since there is no water float as in washed coffee, meticulous hand sorting is needed to ensure coffee quality. One thing that we always find exciting is to see how diet approaches incorporate and leverage coffee’s energy boosting and appetite suppressing qualities.. One of the more interesting ways it is being used currently is with butter coffees popular among those who follow a ketogenic diet. Notify me of follow-up comments by email. Required fields are marked *. For example, if a coffee is very dense and its bean size is very small, I know that I can push that coffee with a large amount of heat; the coffee has the cellular structure to accept the heat without scorching, which gives me a wide variety of profiling options. Sorry, your blog cannot share posts by email. Until I feel adventurous again, this is the coffee I'll be sticking with. Sorry, your blog cannot share posts by email. So whether you’re thinking of upgrading the office joe, or considering offering coffee as a perk for the first time, here are five great reasons why spending a little on coffee can be a worthy investment. Modulation of this phase primarily has to do with body; it is the easiest way to place emphasis on or or compensate for a given coffee’s mouthfeel characteristics. For the sake of this example, let’s say that the coffee is a high density, medium bean size coffee from Colombia, and that in the sampling process I found the coffee to have primary notes of chocolate and brown sugar with a back note of red grape, medium-full body, and mild acidity.
