Do You Have To Use The Milk Within 7 Days Of Opening
You have to use the dairy products including milk within seven days of opening. The milk will begin to spoil after this time and may not be safe to consume. Many people choose to store milk in the fridge for up to seven days without any negative effects.
The labels on most almond milks, as well as other alternative milks like soy, oats, and cashews, recommend that you consume products within seven to 10 days after you open them. Once opened, unopened, refrigerated store-bought almond milk only lasts about 7-10 days, so make sure you finish within 10 days, at the latest. For shelf-stable almond milk, once it is not opened and stored at room temperature, you can expect this beverage to last for 3 to 4 weeks, even past its expiration date.

For refrigerated, unopened almond milk, you always need to keep them in the fridge, otherwise, they may spoil in one day. The average shelf life for homemade almond milk is about 3-5 days, provided that you keep your drinks appropriately stored in a sealed container. If you are making homemade almond milk from scratch, it has a much shorter shelf life than the manufactured variety–only about three days in the fridge, says Sonya Ortiz. Unless you store it in a refrigerator, you will want to use your milk right away, since it will last just a couple hours at room temperature.
| Storage | Shelf life |
| In refrigerator | 12-14 days |
| At room temperature | 2 hours |
If you purchase refrigerated almond milk (milk sold in refrigerated sections), you need to keep your beverage inside your refrigerator once you get home. It is best to keep your milk toward the back of your fridge, where it is more likely to remain cold, even if the fridge door is left open. When milk is stored on a shelf by the door, it is exposed to hot air every time it is opened, encouraging the growth of bacteria.
Each time a fridge door is opened, it allows hot air in, which allows the bacteria in milk to grow at higher rates. The change of temperature caused by opening your fridge, and even taking your milk out to drink, increases the chances of the bacteria growing, too. Every time you open your milk container, the air allows for growth of Lactobacillus bacteria, which converts lactose in the milk into lactic acid, turning your milk rancid past its Use By date or Best By Date.
Once opened, according to Eat By Date, all milk will be safe for four to seven days beyond its printed date, provided it is refrigerated. Opened milk lasts a week after the date it was sold, and non-opened milk may last longer than one week, depending on the milk type. While there is no set recommendation, most studies indicate that, as long as properly stored, unopened milk typically stays good for 5-7 days past the listed date, whereas opened milk will last for at least 2-3 days beyond this date (3, 8, 9).
For example, if I bought milk today with an August 27th shelf life, it would last 15 days, which is just over two weeks. If you are able to keep the milk about five days past its sell-by date, subtract your current date from its sell-by date, add five, and you will get how many days this milk will last. The conclusion is, even with a better pasteurization process and storage conditions, a stored sell-by date should not exceed 21 days from when milk leaves the cow.
In fact, an expiration date on the carton of milk reflects the last day an unopened carton of milk can maintain its freshness and quality. The printed date does not mean your milk is going to expire or that it is unsafe to drink right after this date. It is important to note that the shelf life dates differ depending on the type of milk you buy, the way that the milk is stored, and the way it is packaged.
Just because plant-based milk does not contain dairy does not mean that it does not expire, or can sit in an open container for an extended time. Some sources say that your milk is fine beyond the shelf life, while others say throw it out within just a few days of opening. If you have done a good job of preserving the milk, it may still be usable after its supposed expiration date.
If you are not able to use the milk before it expires, you can freeze it safely for up to 6 months. As I mentioned, stable-shelf milk, when stored properly, can be kept up to 3 weeks past the expiration date. Unopened, UHT milk typically can last 2 – 4 weeks after its printed date, when stored in a cool, dry pantry, or as long as 1 – 2 months in a refrigerator. If unopened, full-fat milk lasts five to seven days, reduced-fat and skimmed milk lasts seven days, and fat-free and lactose-free milk lasts seven to 10 days after the printed date, when refrigerated.

Unopened whole milk typically will be good for five to seven days after its printed expiration on a carton or jug, according to dairy packager Stanpac, whereas reduced-fat and skim milk last for seven days. The major problem this raises is there may be situations in which you open your milk, seven days go by, and yet the expiration date printed on the carton has not passed. This is because sometimes the milk goes bad after just one to two days, because it is contaminated in some way since opening. You Can Thaw Almond Milk For Cooking If you still have not opened the carton of almond milk, then you need to place the entire carton in your refrigerator.
Sonia Ortiz says that many brands of alternative milks will say that its best consumed within 7-10 days after you open the package, as this is a standard warning on perishable products. This might be surprising for most – but according to guidelines* from the Singapores Food and Veterinary Authority (AVA), fresh milk is best consumed within three days after it is opened.
Since refrigerating milk typically makes it last faster, many people assume it stands to reason that freezing a beverage would guarantee it could remain fresh longer. One study found that your fridge temperature significantly impacts the amount of time that your milk stays good beyond its listed expiration date. Dr. Pasteur pointed out the paper by the Cornell Milk Quality Improvement Program (it is a thing) which says shelf-life is determined by refrigeration the milk to its minimum chilling temperature – around 45oF – and seeing how many bacteria are present in the milk after X number of days.

How long will Opened milk last in the fridge?
It is advisable to store fresh milk in the refrigerator at 4°C and consume it within three days of opening, despite the common misconception that milk will remain fresh as long as it is consumed before its “use by” date. Even two hours without the milk in the refrigerator could cause it to deteriorate.
What happens if you drink spoiled milk?
Beyond an unpleasant taste, a small sip of spoilt milk is unlikely to produce any symptoms. Larger quantities of spoilt milk might upset your stomach and result in nausea, vomiting, and diarrhea (like a food-borne illness). The majority of the time, ingesting spoilt milk-related symptoms go away within 12 to 24 hours.
Is it safe to cook with spoiled milk?
Yes, you may bake using sour milk. Baking is a terrific way to use spoilt milk, even though you might not want to drink it straight up. In fact, the increased acidity that milk develops with age can enhance the flavor of baked items like cakes and muffins. Dan Barber enjoys making food using sour milk.
