Tips and tricks
Savor the Superior flavor
Even though tasting is an individual art, there are a few steps, which if followed, will take your beer tasting to a blissful level.
Take pause and marvel at its greatness before you partake of it. Raise the beer in front of you, but don't hold your beer to direct light as this will dilute its true color.
Swirl your beer, gently in the glass. This will pull out aromas, slight nuances, loosen & stimulate carbonation and test head retention.
90-95% of what you experience is through you sense of smell. Breathe thru your nose with two quick sniffs, then with your mouth open, then thru your mouth only (nose and mouth are connected in the experience). Let olfaction guide you. Agitate again if need be, and ensure that you are in an area that has no overpowering aromas. Enjoy its bouquet.
Now sip the beer. Resist swallowing immediately. Let it wander and explore your entire palate. Let your taste buds speak. Note the mouthfeel, the consistency of the liquid's body, and breathe out during the process of tasting. This process of exhaling is called "retro-olfaction" and will release retained stimulations at the mucus and mouthfeel level, but at a higher temperature. At times this will be the same as the olfactory process if not different and complimentary. Try to detect any sweetness, salty flavors, acids and general bitterness.
Also, try tasting the beer after it warms a bit (just a bit mind you). Really cold beer tends to mask some of the flavors. As a beer warms, its true flavors will pull through, become more pronounced.
