How to Store Clove: Whole, Ground and Oil
A small brown bud, slightly oily, fragrant powder, or a bottle of essential oil: clove keeps according to simple rules, with a sharp gap between whole and processed forms. Here are the habits that preserve its aromatic power longest.
Whole clove buds keep in an airtight jar or pouch, away from light and heat: an intact skin protects the essential oil inside well, over 2 to 3 years. Ground powder, more exposed to air, fades within a few months. Essential oil keeps separately, in its original tinted bottle, tightly closed, away from direct light.
This is a practical companion to our page on clove in Ayurveda and our guide how to choose clove.
Why does the whole bud keep so well?
The closed structure of the dried flower bud naturally protects the essential oil it contains (rich in eugenol) from oxidation in open air, unlike already-ground powder whose exposed surface is far larger. Three simple precautions extend this good shelf life:
- Airtight container, glass or metal, closed after each use;
- Grind at the last moment if possible, rather than buying powder already ground;
- Temperate cupboard, away from a heat or humidity source (never near the sink or stove).
What research documents about storing herbal powders
A 2016 study by Sharma, Kabra, Kabra and Baghel, published in the Journal of Ayurveda and Integrative Medicine (see the study on Google Scholar), shows that dried medicinal-plant powders degrade progressively depending on storage conditions — light, humidity and temperature mattering more than the mere passage of time. For clove, this confirms the value of favoring the whole form and grinding only a small amount at a time.
How long does clove keep?
| Form | Storage | Indicative duration | Sign of quality loss |
|---|---|---|---|
| Whole buds | Airtight jar or pouch, away from light | 24 to 36 months | Dry, brittle bud, weaker smell |
| Powder | Airtight opaque jar | 4 to 6 months | Clumping, nearly neutral smell |
| Essential oil | Tinted, airtight bottle, away from light | 12 to 24 months after opening | Altered smell, changed texture |
These benchmarks remain indicative: an aged bud is not dangerous, but a brittle bud or scentless powder has lost most of its culinary value.
Should you refrigerate clove?
No, this is not necessary for the whole bud or the powder: as with most dried spices, moving from the refrigerator to room temperature creates condensation on opening, which encourages unwanted humidity. A temperate cupboard, away from light, remains the best option. The essential oil, meanwhile, keeps at a stable room temperature, never in the refrigerator.
Precautions
Poorly stored clove mainly loses aromatic power, which is not in itself the primary safety concern for this spice. The most important point remains choosing the right product at purchase, detailed in how to tell real clove, along with the precautions specific to this plant: the essential oil is irritating and potentially toxic in excess, off-limits for children without supervision, caution during pregnancy and with blood thinners. For all precautions, see our safety and precautions guide.
Your questions about how to store clove
How long does opened clove powder keep?
As a rough guide, 4 to 6 months in a well-closed opaque jar, kept dry and away from light. It is the form that loses its scent fastest, hence the benefit of grinding whole buds at the last moment.
Do whole cloves keep better than powder?
Yes, noticeably: 2 to 3 years in an airtight container, versus only 4 to 6 months for powder, far more exposed to air once the buds are ground.
How do I store clove essential oil?
In its original tinted bottle, tightly closed, away from light and heat, never in the refrigerator. It generally keeps 12 to 24 months after opening.
How do I know if my cloves have lost quality?
Two main signs: a texture that has become dry and brittle rather than supple and oily, and a noticeably weaker smell once pressed between your fingers.
