It requires a discerning palate, a vocabulary of descriptive words and, presumably, for when drinking the modern craftier interpretations, a hipster beard (Michael does have a beard but swears he's not a hipster).
Although beers in the awards are judged on their adherence to style (lager/pilsner, pale ale/IPA, stout/porter, sour, hazy, hefeweizen or the aforementioned doppelbock or dunkelweizen, for example), the judges are looking for balance, drinkability and straight-up enjoyability.
The result is less a strict technical exercise in congratulating brewers for beer correctness and more a list of brews you would happily recommend to friends.
How to taste a beer like the professionals
So, how should you judge a beer?
1. Have a look
For starters, the beer should always be poured into a glass, which allows you to look at the liquid, take in the aroma and is better for tasting. Consider the colour and clarity. Does the beer retain a good head?
2. Have a sniff
Give the glass a swirl and stick your nose in to take in the aroma. It could be citrusy, give coffee notes or have a slight sulphur or medicinal quality - there will be many scents vying for your attention.
3. Have a taste
What flavours can you detect? It may be hoppy with notes of citrus or stone fruits, it may be malty or have tones of caramel. Consider the sweetness or lack thereof and think about the beer's finish and aftertaste as well as characteristics such as balance, bitterness and mouthfeel.
4. Simply enjoy it
Just taking time to consider what you are drinking is a great start and, until you've earned your stripes as a beer judge, try the top 30 and see if you agree with the results. My bet is you will.
