Quick Answer
Yes, creme de menthe should be refrigerated after opening to maintain optimal flavor and quality. Creme de menthe is an alcoholic liqueur with a dairy or cream base, so it can spoil if left unrefrigerated. Refrigeration helps prevent the liqueur from going bad and retains its original taste and aroma. An unopened bottle of creme de menthe can be stored in a cool, dry place for up to one year. Once opened, it’s best to refrigerate creme de menthe and use within 4 to 6 months.
What is Creme de Menthe?
Creme de menthe is a sweet, mint-flavored liqueur made from grain alcohol, sugar, coloring, and mint oils. It has a creamy, smooth texture due to the addition of dairy ingredients like cream or milk. There are two main types of creme de menthe:
- Green creme de menthe – This is the most common and recognizable variety. It gets its green color and distinctive minty flavor from natural extracts like peppermint or spearmint oil.
- White creme de menthe – As the name suggests, this version has a clear, colorless appearance. It has a lighter, more subtle mint flavor derived from extracts like pennyroyal or wintergreen.
Both green and white creme de menthe contain approximately 24% alcohol by volume. The liqueur has a syrupy consistency and thick, velvety mouthfeel.
Does Creme de Menthe Need to be Refrigerated?
Yes, creme de menthe should always be stored in the refrigerator after opening. There are a few reasons why proper refrigeration is important for an opened bottle:
1. Prevent Spoilage
The dairy products in creme de menthe can go bad if left unrefrigerated for too long. Exposure to heat and air causes the cream to oxidize and curdle over time. Refrigeration keeps creme de menthe fresh by slowing down this spoilage process. The cold temperature helps prevent bacteria growth and extends the liqueur’s shelf life.
2. Retain Flavor
The delicate mint oils that give creme de menthe its distinctive flavor can degrade rapidly at room temperature. Refrigeration helps lock in the robust mint essence and prevents evaporation of the volatile flavor compounds. Proper storage keeps creme de menthe tasting bright and refreshing for a longer period.
3. Avoid Separation
The dairy ingredients may start to separate from the alcohol if creme de menthe is left unrefrigerated. This can give the liqueur a curdled appearance and an unpleasant texture. Refrigeration at around 40°F (4°C) helps maintain the creamy emulsion and prevents the ingredients from separating.
4. Follow Manufacturer Guidelines
Most brands of creme de menthe have labeling that specifies “Refrigerate after opening.” This storage guidance ensures the product retains its quality and will meet customer expectations. Refrigerating opened creme de menthe aligns with the recommendations from manufacturers.
How to Properly Refrigerate Creme de Menthe
Follow these tips for refrigerating creme de menthe:
- Make sure bottles are tightly sealed to prevent evaporation and leakage.
- Store upright in the main body of the refrigerator, not on the door where the temperature fluctuates.
- Refrigerate at around 40°F (4°C) for optimal cold temperature without freezing.
- Consume refrigerated creme de menthe within 4 to 6 months for best quality.
- If liqueur becomes too thick after refrigeration, gently mix before using.
- Keep bottles away from strong smelling foods to prevent flavor absorption.

| Guideline | Reason |
|---|---|
| Keep bottle upright | Prevents leaking from cap |
| Store in refrigerator body | Most stable temperature |
| Refrigerate at 40°F (4°C) | Optimal coldness without freezing |

How Long Does Creme de Menthe Last in the Fridge?
Properly stored creme de menthe will retain its flavor and quality in the fridge for 4 to 6 months after opening. The exact shelf life depends on factors like:
- Type of creme de menthe – White creme de menthe may last slightly longer than green.
- Storage conditions – Constant 40°F (4°C) temperature extends shelf life.
- Bottling – Well-sealed bottles prevent air exposure.
- Cleanliness – A clean fridge slows spoilage.
Over time in the fridge, creme de menthe may start to lose its vibrant aroma, develop separation, or become more viscous. If a creme de menthe bottle shows significant changes in appearance, odor, or texture, it should be discarded.
An unopened bottle of creme de menthe has a longer shelf life of around 1 year stored in a cool, dark place. Once opened, creme de menthe enters the countdown toward spoilage, making refrigeration necessary.
How to Tell if Creme de Menthe has Gone Bad
Here are some signs that opened creme de menthe has spoiled and should be discarded:
- Appearance – Separated liquid, curdling, cloudiness, film on top
- Aroma – Sour, unpleasant, rotten, or loss of rich minty smell
- Flavor – Sharp, biting taste; very weak or no mint flavor
- Texture – Extremely thick and syrupy, crusted around bottle cap
- Bottle – Bloating, puffed up appearance
If your refrigerated creme de menthe displays these common signs of spoilage, it’s best to discard the liqueur. Consuming spoiled creme de menthe can potentially cause health issues.
FAQs
Should creme de menthe be stored in the fridge door?
No, creme de menthe should not be kept in the refrigerator door. The temperature there fluctuates too often as the door opens and closes. Store creme de menthe bottles in the main body of the fridge where the temperature remains stable.
Can you freeze creme de menthe?
Freezing is not recommended. The dairy content and high alcohol percentage of creme de menthe makes it prone to freezing solid and separating when thawed. Refrigeration at just above freezing (40°F / 4°C) is ideal.
How do you store an unopened bottle of creme de menthe?
An unopened, sealed bottle can be stored in a cool, dry place like a pantry for up to 1 year. Keep the liqueur away from heat and light until ready to use. Once opened, refrigerate immediately.
Does creme de menthe need to be refrigerated during shipping?
No, creme de menthe does not require refrigeration during transit. As long as the bottles remain properly sealed, a few days at room temperature won’t cause issues. Refrigerate as soon as possible after receiving shipment.
Conclusion
In summary, creme de menthe liqueur requires refrigeration after opening to prevent spoilage and retain its signature minty flavor. The dairy content in creme de menthe can curdle if left unrefrigerated for extended periods. An opened bottle should be stored in the refrigerator at around 40°F (4°C) and consumed within 4 to 6 months for optimal taste and quality. Signs of spoiled creme de menthe include separation, clumping, foul odor, and altered flavor. With proper refrigerated storage, creme de menthe stays creamy and delicious for months after opening.
