Tasting is comparing and contrasting, you can compare them in terms of your personal preference, but also in terms of aroma, acidity, body, and flavor.

Aroma is the first sign of how your coffee will taste. In fact, most of your sense of taste actually comes from your sense of smell - which is why coffee can taste so satisfying and sublime.

Acidity , in tasting terms, doesn't mean sour or bitter; it's a lively, tangy, palate-cleansing property, ranging from low to high.

Body is the weight or thickness of the beverage on your tongue. Body ranges from light to full.

Flavor is the all important melding of aroma, acidity, and body that creates an overall impression.
