Yogurt has a number of varieties and flavors such as frozen yogurt, low-fat yogurt, drinkable yogurt, Greek yogurt and yogurt with fruits. This is why it is considered a very popular dairy product around the world.
It should be kept in mind that the “sell by” date indicated on the packaging of the yogurt usually means the last date in which the manufacturer will guarantee for the yogurt’s superb quality, not its safety. According to the manufacturers, the yogurt’s quality is guaranteed for up to 7 days beyond the “sell by” date.
To add, manufacturers agree that the yogurt can still be consumed even after 7 days from the “sell by” date and it will still be safe. Because of this difference, you may still compliment your meals with the said yogurt and you won’t have any health concerns after consumption.
Frozen yogurt can last up to three months if properly stored in the freezer. Drinkable yogurt can last up to two months inside the freezer and 10 days in the refrigerator. For Greek yogurt, storing inside the fridge can make the yogurt last for a week or two, inside the freezer, a couple of months.
Low-fat yogurt can last up to two weeks if stored in the fridge and two months if stored in the freezer. For yogurt with fruits, it can last up to 10 days inside the fridge and two months inside the freezer. For regular ones, it can last three weeks inside the fridge and two months inside the freezer.
In the case of yogurt that has been opened, you may limit it to a week inside the refrigerator and a month inside the freezer. This is of course, if you store them properly by tightly covering it.
