Exact Answer: 3 Days To 4 Days
When beer is stored in the growler, then it can last for anywhere from a minimum of 3 days to as long as 4 days. There is not a fixed time for how long the beer would last in the growler. The reason behind that is that the time for how long the beer would last in the growler depends upon several different factors.

Some of the major factors upon which the time for how long the beer would last in the growler could be the condition of the growler, external temperature of the growler, storage conditions of the growler, all the measures followed to make the growler last longer and other such factors.
How Long Does A Growler Last?
|Kept opened||1.5 days to 2 days|
|Kept sealed||3 days to 4 days|
But apart from all these factors, there is one major time-determining factor that must be considered while calculating the time for how long the beer would last in the growler. That major time determining factor is whether the beer in the growler is kept open or if the growler is kept closed.
The time it takes for beer to go bad when kept in the growler is shorter when it is kept open or uncapped as compared to when the beer in the growler is kept closed.
In most general cases, beer in the growler lasts for about a minimum of 1.5 days to a maximum of 2 days on average when the beer in the growler is kept opened or uncapped.
While on the other hand, beer in the growler lasts for about a minimum of 3 days to a maximum of 4 days on average when the beer in the growler is kept in sealed and airtight packaging.
Why Does A Growler Last That Long?
It is not much of a surprise that if the growler is kept open, that is to say, that the growler is kept uncapped, then the beer would be exposed to the outside. When beer comes in contact with the external atmosphere, then many atmospheric agents such as oxygen and moisture react with the bear.
As a result, the beer which is kept in the growler not just loses its spark, but also loses its authentic taste and rather tastes bland and not more like a beer. Thus it is always recommended to store the beer in the growler in a sealed tight package such that the beer is not exposed to the atmosphere.
Apart from the external atmosphere, if the growler is kept open or uncapped then it becomes more exposed to the external temperature. High temperature, as in the case of summer, can also result in making the beer lose its authentic taste and spark, resulting in making the beer blander.
While on the other hand, during winter, the atmosphere is a lot humid. In simple words, it can be said that there is a lot of moisture in the air which also results in making the beer lose its authentic taste and spark, resulting in making the beer more distasteful.
All these reasons add up to why the shelf life of beer, when stored in the growler, is shorter when it is kept opened or uncapped as compared to when beer is stored in the growler but is kept in sealed airtight packaging.
Temperature also plays a vital role in determining the time for how long a growler would last. Generally, low temperatures promote a longer life expectancy of the beer kept in the growler.
Thus it is always recommended to store the growler in the refrigerator when it is kept indoors, or in a tub of ice when it is taken anywhere outdoors. Keeping the growler at a low temperature can increase the shelf life of the beer kept in the growler from about a minimum of 1 day to a maximum of 2 days.
Lastly, if the beer is stored in the growler in a sealed and airtight packaging, and is kept in low temperature, that is around 3 degrees Celsius to 5 degrees Celsius, then the growler can last from about a minimum of 3 days to a maximum of 7 days.
