A good beer is one that pleases all the five senses. It should be appreciated with the eyes, the nose, the mouth, the touch and even with the sound.

The eyes help see the colour, clarity and the foam of the beer. A dark looking beer will be perceived as a bit bitter and a cloudy light coloured one might be a wheat beer. When you nose a beer, you can pick up the aromas of the additives like fruits, flowers, hops, grass, malt, honey etc.
There is no such thing as a bad beer. It’s that some taste better than others.
Billy Carter
The mouth of-course presents to the palate the taste that is a combination of carbonation, acidity, sweetness and bitterness. Interestingly the serving temperature of the beer sensed through your skin also adds to the experience of beer appreciation. And finally they say that listening closely to the effervescence can help one appreciate the viscosity of different beers.
So don’t just gulp it down, take time to hold on to the good and be a beer sommelier.
