Buttermilk is a popular dairy product around the world. It is produced by introducing lactic acid to the whole milk, which in results in the production of bacteria. It has various benefits such as it contains calcium, potassium and phosphorous.
However, the shelf-life of the buttermilk is usually influenced by the ways it is stored. The processing method, its carton date and exposure to the daylight or heat defines its durability. Mostly, people are concerned that how long does buttermilk last?
So, it lasts when properly processed and stored below the temperature of 40°F. if in case, the carton is open and not consumed within the 3 days of the span, then it may release watery substance on top and rest high volume butter sediments’ on the bottom of the container leaving a fermented taste.
According to the Wikipedia, buttermilk is a very healthy drink which all age group should consume to have healthy digestive system.
What Are Buttermilk Anyway?
We had a misconception before reading the literature about buttermilk, that it is a buttery texture high-fat milk product. But, actually, it is a low-fat sour milk product which is extracted from the butter or whole milk i.e. the fermented part of the milk cream.
It is a residual liquid which is extracted after the whole milk cream is churned up to a certain level that cream becomes white butter and its milk is separated in the container.
Either you can collect full cream from the top of the milk bowl every day and refrigerate it, or else you keep the cream that is visibly thicker on the top of the milk bowl overnight.
Let it ferment for a night and in the morning you will see after churning that milk is separated from the buttery texture. This is the buttermilk which you can drink early morning including a pinch of white or black salt.

Does Buttermilk Go Bad? How Long Does Buttermilk Last?
Yes, buttermilk goes bad when it is not stored properly in the refrigerator or kept below 40 degrees Fahrenheit. We are more concerned about the buttermilk when we are using it in cooking.
Buttermilk can last up to 2 weeks after opening if it is kept in the freezer in an airtight container. You must leave a space in the container for air so that the buttermilk could stabilize the temperature easily.
Freezing is the only quick and most safe method to increase the durability of the buttermilk. Consequently, if you are willing to keep buttermilk at home to drink then again there are 2 conditions:
Condition 1- if the buttermilk is extracted at home through the natural churning process then the quality of buttermilk is pure enough and could not be stored openly for a long period. In this condition, you cannot store the residual liquid for more than 24 hours. This condition prevails because no preservatives of pasteurized compounds are added to maintain the quality of the buttermilk at home.
Condition 2- when we use commercially made buttermilk that is packed in tetra pack, then we have the option to store for several days in the refrigerator. A commercial buttermilk packing is also stored for 6 months if unopened. After opening for drinking or cooking use, then it should be refrigerated at a cool level for next 3 days.
There are some signs indicate whether the buttermilk has gone bad or not.
It is normal to see the water and some milk substance to sediment, but if the consistency of the buttermilk doesn’t come to its natural state after shaking properly, then it should be discarded.
Always check the lip of the carton which you opened recently for mold formation. By the way, buttermilk is a spoiled product already.
So, you may not be able to figure out by tasting its ferment taste. It is better to check the container inside and its opening for molds. If any suspicious mold formation found then discard immediately.

Buttermilk which is found watery and consistency of the butter is not smooth or thick as it was when opened for the first time, then it may be spoiled in the fridge and should be discarded immediately because a spoiled buttermilk may lead to a stomach infection.
A week after refrigeration, you should take a sip of the buttermilk. Before that, transfer the content into a transparent glass to see the color of the buttermilk. If it is still slightly creamy and off-white in color then take a sip. If the color of the buttermilk turns pale yellow and water that has come up is not mixing with the buttery content, then you must discard.
