How long is prickly pear syrup good for?

Prickly pear syrup is a sweet, versatile syrup made from the juice of prickly pear cactus fruits, also known as cactus pears or tunas. It has a gorgeous pink or red color and a lightly floral, sweet taste. Prickly pear syrup is popular in Mexico and the American Southwest, where it’s used to flavor beverages, cocktails, sauces, desserts, and more. But how long does prickly pear syrup stay fresh and retain its delicious flavor? Here is a detailed look at the shelf life and storage recommendations for prickly pear syrup.

What is Prickly Pear Syrup?

Prickly pear syrup is made by extracting and reducing the juice from the pulp of prickly pear cactus fruits. To make prickly pear syrup:

  • Prickly pear cactus fruits are harvested when ripe.
  • The spines and skin are removed from the fruits.
  • The pulp and juice are extracted and strained.
  • The prickly pear juice is boiled down to reduce water content and concentrate the natural sugars.
  • The reduced juice is bottled as syrup.

This produces a tart yet sweet, vibrantly colored syrup with the unique flavor of prickly pears. Some prickly pear syrups have extra sugar added, while others just use the natural sugars in the fruit.

The prickly pear cactus (Opuntia species) is native to the Americas and has been used for food and medicine for thousands of years. The paddle-shaped pads are edible when young and the ripe fruits are enjoyed fresh or used to make juices, jams, candies, and more.

Prickly pear syrup emerged as a traditional product in Mexico, where it’s known as jarabe de tuna. It also became popular in the southwestern United States. Prickly pear syrup has a jam-like consistency and is used like fruit syrups and honey.

Shelf Life of Prickly Pear Syrup

An unopened bottle of prickly pear syrup has a relatively long shelf life of up to 2 years or 24 months when stored properly. Once opened, the syrup will stay fresh for 12-18 months.

The high natural sugar content and acidic nature of prickly pear syrup create conditions where microbes have difficulty growing. This gives the syrup some natural preservative properties. The boiling process during production also eliminates harmful microorganisms, creating a very shelf stable product.

As long as the syrup bottle remains sealed and stored appropriately, prickly pear syrup can be enjoyed for up to 2 years from the production date before quality starts to decline. However, it’s best consumed within 12-18 months of opening for maximum flavor and freshness.

Unopened Prickly Pear Syrup

  • Shelf Life: Up to 2 years (24 months)
  • Store in a cool, dark place
  • Keep the syrup bottle sealed

An unopened bottle of prickly pear syrup has an excellent shelf life. The sealed container protects the syrup from air, light, and germs that could cause it to deteriorate. Stored in a cool, dark pantry or cupboard, prickly pear syrup can maintain top quality for 2 years from the production date.

Refrigerating an unopened prickly pear syrup isn’t necessary. But it also won’t do any harm. Some separation may occur in the colder temperature, but will remix when stirred.

As long as the syrup bottle is kept sealed and not exposed to direct sunlight or high heat, prickly pear syrup stays fresh for up to 24 months before opening.

Opened Prickly Pear Syrup

  • Shelf Life: 12-18 months
  • Refrigerate after opening
  • Keep container sealed between uses

Once exposed to air, prickly pear syrup has a shorter shelf life. But it still keeps well refrigerated for 12-18 months.

Keeping prickly pear syrup chilled after opening helps prevent microbial growth and slows chemical reactions that lead to spoilage. Always seal the container tightly between uses.

Over time, opened prickly pear syrup may start to darken, lose its bright color, crystallize, or develop off flavors. Discard syrup that is older than 18 months or shows any signs of spoilage.

For maximum freshness, use opened prickly pear syrup within about a year. But it can often last up to 18 months refrigerated when stored properly.

How to Tell if Prickly Pear Syrup Has Gone Bad

Prickly pear syrup has a long shelf life, but it’s important to know how to identify signs of spoilage. Here’s what to look for to determine if prickly pear syrup has gone bad:

  • Off odor – Fresh prickly pear syrup smells sweet and slightly floral. Discard if the aroma is sour, fermented, or unpleasant.
  • Mold – Visible mold, even just a few spots, means the syrup should not be consumed.
  • Texture changes – Crystallization, separation, excessive thickening, or thinning are red flags for old syrup.
  • Color changes – Unnatural darkening, dulling, or uncharacteristic colors indicate spoilage.
  • Bubbles – Small bubbles throughout could signal fermentation; discard.
  • Sliminess – Increased viscosity or stickiness signals microbes; do not eat.

Taste can also identify a spoiled syrup. Rancid, bitter, or sharp flavors are signs prickly pear syrup has gone bad and should not be consumed.

As always, if there is any doubt about the safety of a syrup, it’s best to throw it out. But sealed, refrigerated prickly pear syrup often lasts up to 18 months with its fresh flavor and appearance intact.

Does Prickly Pear Syrup Go Bad Once Opened?

Prickly pear syrup does have a shorter shelf life once opened. But refrigerated, tightly sealed syrup can still stay fresh for 12-18 months after opening.

Exposure to oxygen and contamination introduced through opening both reduce the shelf life of prickly pear syrup. But the naturally high sugar content and acidity help preserve it for over a year.

To help maximize the shelf life of opened prickly pear syrup:

  • Refrigerate after opening
  • Store in a tightly sealed container
  • Keep air exposure to a minimum
  • Use clean utensils each time
  • Watch for any signs of spoilage

With proper refrigerated storage, prickly pear syrup can maintain quality and remain safe to eat for about a year after the seal is broken.

Does Prickly Pear Syrup Need to be Refrigerated?

Refrigeration is recommended for opened bottles of prickly pear syrup to extend the shelf life. However, unopened prickly pear syrup does not need to be refrigerated.

Unopened Prickly Pear Syrup

An unopened, sealed bottle of prickly pear syrup can be stored at room temperature in a cool, dry pantry. Refrigeration is not required. The syrup has a shelf life of up to 2 years without being refrigerated as long as the bottle remains sealed.

Opened Prickly Pear Syrup

Once opened, it’s best to store prickly pear syrup in the refrigerator. The cold temperature helps slow chemical changes and prevent microbial growth. Refrigeration extends the shelf life of opened prickly pear syrup to about 12-18 months.

Without refrigeration, opened prickly pear syrup may only last 6-8 months before quality declines. It’s not harmful, but becomes less fresh, flavorful, and aromatic over time. Refrigeration is the best way to preserve the taste and quality after opening.

Should Prickly Pear Syrup be Refrigerated After Opening?

Yes, prickly pear syrup should be refrigerated after opening to maximize its shelf life. Keep opened prickly pear syrup stored in the fridge in a tightly sealed container. Proper refrigeration allows the syrup to stay fresh for up to 18 months.

How to Store Prickly Pear Syrup

To get the most out of each bottle of prickly pear syrup, follow these tips for proper storage:

Unopened Prickly Pear Syrup

  • Store in a cool, dark pantry or cupboard
  • Avoid direct sunlight and heat over 75°F
  • Keep upright in a tightly sealed bottle
  • Can be refrigerated for extra freshness, if desired
  • Always wash hands before handling
  • Shelf life up to 2 years from production date

Opened Prickly Pear Syrup

  • Refrigerate after opening
  • Use clean utensils each time
  • Keep tightly sealed between uses
  • Wipe clean any drips from the bottle
  • Watch for signs of spoilage
  • Consume within 12-18 months

Proper storage keeps prickly pear syrup tasting great while eliminating food safety risks. Follow the above guidelines to enjoy prickly pear syrup at its best.

Can You Freeze Prickly Pear Syrup?

Yes, prickly pear syrup can be frozen to extend its shelf life even longer. Freezing stops chemical reactions that cause food spoilage.

To freeze prickly pear syrup:

  • Make sure syrup is fresh and unopened or recently opened
  • Pour syrup into freezer-safe containers, leaving 1⁄2 inch headspace
  • Seal containers tightly
  • Label with contents and freeze-by date
  • Freeze for up to 1 year

The freezer time stops the clock – syrup will stay fresh for up to 1 year frozen. Thaw refrigerated or in cold water. Use thawed syrup within 2-3 months.

Freezing prickly pear syrup allows it to keep even longer than refrigeration alone. It preserves both opened and unopened bottles. And freezing returns no quality loss once thawed.

Can You Refreeze Prickly Pear Syrup?

Previously frozen prickly pear syrup can be safely refrozen as long as it still contains ice crystals and has not been left at room temperature for extended periods. Take these precautions:

  • Refreeze syrup immediately after thawing, before any bacteria can grow
  • Do not thaw at room temperature or re-freeze syrup that’s sat thawed for over 2 hours
  • Inspect for signs of spoilage before refreezing
  • Refreeze in airtight containers
  • Use within 2-3 months for best quality

With proper handling, refreezing prickly pear syrup is safe and effective. Limit time thawed and refreeze immediately for best results.

Refrozen prickly pear syrup may lose some texture and flavor nuance over multiple freezes. But it will remain safe to consume within 2-3 months.

Only refreeze prickly pear syrup that has been kept chilled and handled properly after thawing. And of course, never refreeze syrup that has gone bad. With some care, prickly pear syrup can be frozen, thawed, and refrozen again while retaining its delicious sweetness.

What is the Best Way to Thaw Prickly Pear Syrup?

The best method for safely thawing frozen prickly pear syrup is in the refrigerator. Thawing in the fridge minimizes risk and maintains quality.

  • Refrigerator thawing: Place frozen syrup in refrigerator. Thaw overnight or for 24-48 hours. Once thawed, use within 2 weeks.
  • Cold water thawing: Seal syrup in bag, then submerge in cold water. Change water every 30 minutes until thawed. Use immediately.
  • Microwave thawing: Using microwave-safe container, microwave syrup on defrost setting or low power. Stir frequently and use right away.

Always thaw prickly pear syrup gently using cold temperatures. Do not leave at room temperature or thaw in hot water. This raises the risk of bacterial growth in the “danger zone” temperature range.

For food safety, thaw in the refrigerator whenever possible. This keeps the syrup chilled while thawing over 12-24 hours. Handle thawed syrup promptly and do not refreeze until ready to use. With proper thawing, frozen prickly pear syrup returns to an ideal, spoonable consistency.


Prickly pear syrup can have an impressively long shelf life. When sealed and stored properly, prickly pear syrup lasts up to:

  • Unopened: 2 years at room temperature
  • Opened: 1-1.5 years refrigerated
  • Frozen: 1 year frozen

Once opened, keep prickly pear syrup refrigerated and tightly sealed. Discard if it shows any odd textures, colors, smells, or flavors. Freezing extends the shelf life even further.

With its naturally high sugar content and acidity, prickly pear syrup resists spoilage very well. Follow the recommended storage guidelines and prickly pear syrup can retain its delicious sweet taste for up to 2 years, even once opened. Enjoy its unique flavor for months or years by understanding how to best store prickly pear syrup.
