IT IS NOT! When the beer is cloudy, that is no reason to think it is also spoiled! Beers can be cloudy/hazy for a number of reasons. For example, wheat beers are always more cloudy due to the high presence of wheat malt in them. Wheat malt has a lot of protein and increases the cloudiness of the beer. Yeast can also be one of the reasons for a beer to be cloudy. Certain yeasts have a weaker sedimentation ability and remain in suspension, giving the beer a cloudy appearance and a specific taste. Oats in beer can also affect its cloudiness. All of these are normal factors that can affect the cloudy appearance of the beer, but one must know that sometimes cloudiness simply indicates that the beer is young. Young beer is a beer that hasn’t yet finished fermentation. In it, the yeast is still in high suspension and the beer then has a strong yeasty and bitter taste. Such a beer looks the same as some NEIPA or Hazy IPA, but in fact it is a young beer that has not fully fermented. In such cases, therefore, you will only be able to rely on your own tasting abilities when evaluating. Still, you will rarely get young beer in a café or shop.
