Recently, we covered a review on coffees and made a comparison to the label on a fine wine bottle, so we thought we’d share an article that talks about aromatic profiling in coffee. Did you know that you can actually detect subtle flavors of spice, butter, caramel, and smoke even in your coffee? Learn how it all happens in this article from coffeereview.com by Sébastien Gavillet.
Aromatic Profiling in Coffee
Proper Aroma/Flavor profiling is all too often neglected in Coffee. Coffee Aromas/Flavors are essential to understanding and appreciating coffee. As in wine, coffee gets its aromas or flavors from the soil and the climatic environment in which the coffee plant grows. The coffee variety (genetic) and the method in which the green coffee was processed also contribute to the aromas/flavors. Like wine, coffee has many variables which can affect its quality. Coffee crops can be harmed by insects, freeze and poor storage conditions during harvest, which may lead to moldy and sour flavors. It can also be contaminated during its processing such as in the depulping and washing of the coffee cherries, and lastly, during the final storage conditions where once again several defects can develop on the beans. These problems are not exactly the same but similar to those which occur during wine production. Coffee has different varieties, as does wine, which get their characteristics from the soil (terroir). The core aromatic profile of the end product (in the cup) is defined by these characteristics and by the roasters. The coffee blender creates the finishing touch by assembling different roasts. This is very similar to what consulting winemakers do during the wine blending process. We talk about taste, aromas, flavors, acidity and body in coffee as we do in wine. The main difference between coffee and wine, taste aside, is that coffee is not rated by vintage. Unlike certain wines, roasted coffee does not keep for years. The fresher the roast, the more aromatic the coffee beverage will be. Let it age and you will create unpleasant tastes and aromas; this is especially true for the volatile aromas. The consumer also has an important hand in the outcome of her/his coffee experience as does the wine consumer. In wine, serving temperature, wine glass shape and proper food pairing play an important role in properly enjoying a wine. In coffee this process is a little different. The important factors are the grinding, blending and brewing process. The grinding size and the water temperature play major roles in the proper extraction of coffee aromas/flavors, as well as the quantity and quality of water used to prepare a good cup of coffee. Ultimately, the coffee drinker puts her/his final touch to the coffee beverage.
I like to think of aromatic profiling in coffee as complexity training for my palate. Life is about appreciating its subtlety, is it not?
