Beers are awarded a score out of 20 against specific criteria including appearance, aroma, flavour and body, technical quality and style.
Any beer can win a gold, silver or bronze medal based on its score. Any beer that scores 17 points or higher will be awarded a gold, 15.5-16.9 points is a silver and 14 - 15.4 is a bronze.
To determine trophy winners, all the highest-scoring gold medal winners in the category are then tastes against each other one more time so the judging panel can determine which is considered best.
Judging for the 2018 Australian International Beer Awards will take place from 9 May to 11 May.
