What To Know

  • Beer that is stored in a warm environment will often pour flat, as will beer that is past its expiration date.
  • For example, if it is brewed using a method that involves heating the wort (the liquid mixture of water and malt extract) to a high temperature, it can lose some of its fizz.
  • Additionally, a beer can also lose its fizz if it is exposed to heat or light after it has been brewed.

Has this ever happened to you? You’ve just opened a new beer and are looking forward to that first delicious sip, but when you pour it into your glass, it’s completely flat. Why is this happening? Why is my beer pouring flat?

It was shaken or agitated during transportation or storage.

The beer may have been shaken or agitated during transportation or storage. This can happen if the beer is not stored properly or if it is transported over rough roads.

The beer may also be pouring flat because it is old or has been stored improperly. Beer that is stored in a warm environment will often pour flat, as will beer that is past its expiration date.

Finally, the beer may be pouring flat because it is a low-quality beer. Some beers are simply not brewed to a high enough standard and will often pour flat, regardless of how they are stored or transported.

It wasn’t stored properly.

It wasn’t stored properly.

Instead of being stored upright, the beer was stored on its side. That means that the yeast and sediment settled in the bottom of the can or bottle, instead of staying in suspension. When you open the beer and pour it, that settled yeast and sediment will pour out first, resulting in a flatter beer.

It’s past its expiration date.

If your beer is pouring flat, it may be past its expiration date. The expiration date is the date after which the beer will no longer taste fresh and may begin to oxidize. Oxidization causes the beer to lose its color, flavor, and aroma, and can result in it tasting flat. Beers that have expired typically become clearer in appearance and may also develop a sour or bitter taste. It is therefore best to drink your beer before its expiration date.

It was exposed to heat or light.

A beer can lose its fizz for a number of reasons. One of the most common is exposure to heat or light. If a beer is exposed to too much heat or light, it can lose its carbonation and become flat. In some cases, a beer may be exposed to heat or light during the brewing process. For example, if it is brewed using a method that involves heating the wort (the liquid mixture of water and malt extract) to a high temperature, it can lose some of its fizz.

Additionally, a beer can also lose its fizz if it is exposed to heat or light after it has been brewed. For example, if it is stored in a warm environment or exposed to direct sunlight, it can lose its carbonation. It is important to keep beer stored in a cool, dark place to help maintain its fizz.

The container is dirty.

The beer is pouring flat because the container is dirty. The dirt is getting into the beer and making it flat. The dirt is also making the beer taste bad.

Final Thoughts

So, if you’re wondering why your beer is pouring flat, it’s because of how it was handled during transportation or storage.
