Store biltong somewhere cool, dry and airy, and it will keep well for a couple of weeks or more, longer if it is drier. Because biltong is air-dried rather than cooked, moisture is its enemy. Keep it in a breathable bag or paper rather than sealed plastic, out of direct heat, and it holds its texture and flavour nicely. Treat it as the fresh food it is and it will reward you.
How long it lasts depends on how dry it is and how you keep it. If you are still getting to know the food, our beginner's guide to biltong explains why the drying matters so much for storage.
How should you store biltong day to day?
Keep it cool, dry and out of the sun. A paper bag or a breathable container is better than an airtight one, because biltong needs a little air to stop moisture building up and turning to mould. If your kitchen is warm, a cool cupboard or the fridge is fine, just let it breathe rather than sealing it tight.
Avoid leaving it near the hob, a sunny windowsill or anywhere that gets warm and damp. Steady, cool conditions are what biltong likes, much like the air it was dried in. Get the environment right and the beef simply carries on slowly drying, which does it no harm at all.
Should you keep biltong in the fridge?
You can, and in warm or humid weather it helps. The trick is to avoid trapping condensation. Wrap it loosely in paper rather than cling film or a sealed tub, so moisture can escape. If it does pick up a little damp, a short spell somewhere airy will dry it back out.
If you do refrigerate it, let it come back to room temperature before eating for the best flavour and texture. Cold can make it feel harder than it really is. A few minutes out of the fridge and it softens back to how it should be.
How long does biltong last?
It depends on the moisture. Drier, harder biltong can keep for several weeks stored well, while softer, moister pieces are best eaten within a week or so. Ours is made without additives or preservatives, so treat it as fresh food rather than something that sits in a cupboard for months. When in doubt, keep it cool and eat it sooner.
This is a feature, not a flaw. The absence of preservatives is exactly why the ingredient list stays at six: Portuguese beef, Worcester sauce, vinegar, salt, coriander and black pepper. Real food with nothing added does not last forever, and that is a fair trade for knowing what you are eating.
Can you freeze biltong?
Yes, you can. Freezing pauses things and works well if you have more than you will get through soon. Wrap it in portions, freeze, and let it come back to room temperature before eating. The texture holds up well because there is so little moisture in it to begin with.
Portioning before you freeze saves you thawing the whole lot at once. Take out what you need and leave the rest. Because biltong is already low in moisture, it comes back close to how it went in, which is more than can be said for many foods.
Why does moisture matter so much?
The whole idea of biltong is removing water to concentrate the beef and keep it safely. Add moisture back, through humidity or a sealed bag full of condensation, and you undo some of that work. That is when mould gets a chance. Keeping it dry is really about protecting the drying you have already paid for.
This is also why the same pack behaves differently in different homes. A cool, airy kitchen is kind to biltong, while a warm, steamy one is not. Once you understand that moisture is the thing to manage, storing it well becomes obvious.
How do you know if biltong has gone off?
Trust your senses. A sour or off smell, any fuzzy mould, or a slimy feel means it is past its best and should go. Simple white dryness or a firmer texture is just the beef drying further, which is normal. Because it is real air-dried beef, it changes over time rather than staying identical, and that is fine.
If you are ever unsure, it is not worth the gamble. Proper biltong is not expensive to replace against your peace of mind. But most of the time what looks like a problem is just the beef getting drier, which many people actively prefer.
Does biltong need refrigeration?
Not always. Drier biltong keeps in a cool, airy spot, but the fridge helps in warm or humid weather. Either way, let it breathe.
Why has my biltong gone hard?
It has simply dried further, which is normal for air-dried beef. It is still good to eat, and many people prefer it that way.
Can I soften biltong that has dried out?
You cannot really reverse the drying, but letting a hard piece sit at room temperature before eating helps. Many people enjoy the firmer, chewier texture as it is.
How should I store an opened pack?
Reseal it loosely or move it to paper or a breathable container, and keep it somewhere cool and dry. Avoid sealing it airtight while it is still moist, as that traps condensation.
