Coffee Tasting

this is some valuable information about coffee tasting. I am not poetic enough to have written it. Someone else did. Enjoy!


tasting: terms and tools

Coffee tasters use four main categories to help describe and define a cup of coffee. These are acidity, body, bouquet or aromatic profile, and flavor.

* Acidity: this is probably the most important coffee-tasting term, and also the most easily misunderstood. Acidity in coffee tasting is a positive term that denotes a liveliness and vibrancy on the palette, bright taste sensations caused by sugars and other acidic compounds. Coffees are rated as high, medium, or low in acidity according to the overall presence of these qualities
* Body: body describes the texture of coffee and how it feels in your mouth. Density, surface tension, viscosity and other factors determine the perception of body, which is typically rated as heavy or full, medium, and light, depending on if it is thick and creamy or thinner and possibly watery.
* Bouquet: our sense of smell is very involved in the enjoyment and evaluation of coffee, before, during and after we actually taste it. Aromatic profile, or bouquet, is divided into four phases: fragrance, aroma, nose and aftertaste.

Fragrance is perceived in the gases arising from freshly ground coffee.
Aroma is in the gases from freshly brewed coffee.
Nose is perceived in the vapors arising as coffee is swallowed.
Aftertaste is in the vapors that remain after the coffee is swallowed.

* Flavor: flavor refers to the taster’s overall impression of body, acidity, and bouquet. In a general sense it refers to intensity and may also acknowledge particular characteristics such as spice, nut, fruit, or chocolate notes.

The physical tools of the taster are quite obvious: the nose and the mouth/tongue. Key flavors are perceived on different parts of the tongue. Acidity and sweetness are tasted primarily on the tip of the tongue, sourness and saltiness more on the sides, bitterness mostly in the back, and body registers over the whole surface. The nose is an equally important tool, capable of distinguishing between 2000-4000 different aromas. Much of coffee’s flavor is locked up in volatile, aromatic compounds, perceived both directly by sniffing in through the nose, and again during tasting as vapors rise up into the nasal cavity.

While some people are natural “palette people,” blessed with superb sensitivity, it is important to remember that with concentration and practice we all possess the skills to master coffee tasting.
