We recently did a blog on the proper storage of herbs and spices and we thought it would be best to give some tips on the lifespan of spices. One of the most common questions or wonders by many cooks is, do spices go bad? It is easy to think or believe that spices have quite a long shelf life because of them being mostly dried. We tend to think they can last forever.
What you Need to Know
Much as they may not expire like other fresh foods and get mouldy or rotten, they lose their usual taste. It’s safe to say spices don’t really expire, you may notice the spice lose their potency, flavour and colour. It may also be the smell, the peculiar scents that each spice holds tends to get lost.
The shelf-life of herbs and spices depends on a lot of aspects, but majorly it depends on the type, processing, and storage. For instance, whole unground spices and herbs tend to last longer than ground spices, this is because their surface area is exposed to air, light and moisture. Whole spices retain aromatic oils and flavour compounds. Bottom line is that the less processed seasoning is, the longer its shelf life.
Spice Lifespan
Whole spices like nutmeg, peppercorn, cloves, cardamom, and cinnamon can last even up to four years if well stored. Ground spices like ginger, cumin, paprika, chilli powder, and turmeric have a shelf life of up to two to four years. Dried herbs, whether ground or whole, can last up to one to three years.
Unlike many other spices, vanilla extract and salt have an indefinite shelf life. Regardless of its size and shape, salt can be used indefinitely without spoiling or losing flavour. However, if seasoned it may lose its potency over time.
Good or Bad, how can you Tell?
When bought at the stores most spices and herbs have an expiration date indicated on them. This is the date or time that the spices or herbs can still have the most potent flavour and quality. Dried herbs and spices can still be consumed even past their prime, even though the flavour may not be as before.
The easiest way to tell whether it’s time to get rid of your spices is by inspecting the scent and flavour. You can crush or rub a bit of the herb or spice on your hands, if the scent is weak and the flavour is bland, it’s time to let it go. Spices may not be as potent as they were in the beginning but that doesn’t mean you dispose of them. Some spices can be revived back to life by heating them up on a pan on the stove. This could also work for some herbs. It may not be 100% but it could be somewhat successful.
The Secret is in Storage
The only sure way to maximise the shelf life of spices/herbs is by proper storage. Proper storage minimises the exposure to air, heat, light and moisture which reduce spice lifespan. Check our recent blog for more tips on storage. We mostly would love our spices next to our cookers for convenience, as aesthetically convenient as it is, it’s not the best for storage. Cool, dry, and dark environments like the pantry, drawer, or cupboard are the best storage spaces.
Ensure that the spices are stored in tightly-sealed, non-porous containers. Glass and ceramic containers are the best, easy to clean and keep air and moisture out. The most commonly used are plastic containers but they are not the best choice as they absorb the colours and odours. They also are the most difficult to clean for reuse. Unlike what we know, refrigeration does help some spices like paprika and cayenne to maintain their pigment. Refrigeration also helps oil containing spices such as sesame and poppy seeds from becoming gamy.
Make the Most of your Spices
The most efficient way to ensure your spices don’t ‘go bad’ is to maximise their usage. Use up your spices and if they seem to be losing their flavour, colour and taste, there are plenty of ideas to consider. You could create a natural air freshener by brewing spices in a pot with water on the stove, for homemade soap, to make natural easter egg dyes or paints, and to get rid of cockroaches naturally or repel other insects.
The Bottom Line
To maintain the flavours of your favourite dishes, it is important to understand the lifespan of spices. Though spices technically don’t “expire” like fresh foods, they can lose their potency, flavour, and aroma over time. The secret to keeping them staying longer lies in the proper storage. This helps to preserve their quality, as exposure to air, heat, light, and moisture can accelerate deterioration. By storing spices in cool, dry, and dark environments, using tightly-sealed containers, and being mindful of the type and processing of spices, you can extend their shelf life. Remember to trust your senses and inspect the scent and flavour of your spices to determine their freshness. And when spices do start to lose their punch, get creative by repurposing them for natural air fresheners, homemade soaps, or even natural pest repellents. Make the most of your spice collection and savour the vibrant flavours they offer throughout your culinary journey.
