“Sour, like lemon juice, acidic”
Beer flavour standard used to train professional beer tasters to recognize and scale the intensity of sour character.
Acidity in beer is primarily derived from the activities of brewer’s yeast during fermentation. Sour tastes can also be caused by contaminant bacteria and wild yeasts.
