This fat is collected and undergoes further processing such as clarifying to make it suitable for cooking.

As such, the date listed on the bottle is simply an estimate of how long it can stay without raising any food safety concerns. Afterward, freshness is not guaranteed.

Additionally, with lard, it doesn't matter whether you open the package or not because it's not typically preserved with air suction or added preservatives. As long as it has been properly wrapped and stores in temperatures below room temperature, you should be fine.

The traditional way of dealing with lard was to leave it in the pantry and hope for the best, but that's before fridges became an absolute necessity in the kitchen. It's not recommended to leave lard out in the open, especially if it's uncovered.

Uncovered lard is an easy way to attract all manner of insects and rodents to your home. Not to mention that lard left on the shelf is going to go bad in a month or less time.

The best way to preserve lard is to store it in the fridge. This way, it should last for about a year or so. If you don't expect to use it any time soon, throw it in the freezer. Its shelf life should be extended by a year or two if it remains unused.

In this, the most important point to remember is that lard easily absorbs odors and flavors from the air. When storing lard, it's an absolute necessity that you close the container with lid. This should help to further push its best by date because it doesn't interact with the bacteria in the air.

When refrigerating or freezing lard, for example, the optimal way of keeping air out is to wrap it in wax paper and cover it with a piece of foil. Alternatively, the lard can also be cut up into small pieces and placed in a baking sheet with parchment paper. This should be placed in the freezer for about three hours then transferred to a freezer bag and left to sit in the freezer for two years or more.

An important point to remember is that once unfrozen, lard should not be put back in the freezer. It's going to lose its flavor this way. Instead, it should be used in the next few days or so.
