Make the most of every bottle of slush syrup with proper storage tips and shelf life info.
If you’ve stocked up on your favourite Florida Slush Syrups, you might be wondering how long they last, how to store them correctly, and whether they need to go in the fridge. The good news? Our glycerol-free slush syrups are easy to store and designed to stay fresh for a long time when handled properly.
Here’s everything you need to know about slush syrup shelf life and storage, whether you’re using them at home with your Ninja Slushie Machine or keeping bottles on hand for parties and events.
🕒 How Long Does Slush Syrup Last?
Our concentrated slush syrups typically have a shelf life of 12 months when unopened and stored in a cool, dry place.
Once opened, we recommend using the syrup within 30 days for best flavour and consistency — though many customers find they last even longer with good storage practices.
✅ Always check the “Best Before” date printed on the bottle for specific guidance.
🧊 Do I Need to Refrigerate Slush Syrup After Opening?
No refrigeration is required. Our slush syrups are shelf-stable, even after opening. Just be sure to:
- Reseal the cap tightly after each use
- Store in a cool, dry place away from direct sunlight
- Avoid temperature extremes (don’t store next to cookers or in very hot conservatories)
That said, chilling the syrup before use can help speed up freezing in machines like the Ninja Slushie Maker — so feel free to pop it in the fridge before mixing, if you’d like.
🧃 How to Store Slush Syrup Properly (Opened or Unopened)
Follow these tips to keep your slush syrups in top condition:
- Keep bottles upright to avoid leaks or sticky caps
- Wipe the bottle neck after pouring to prevent crusty residue
- Label the opening date if you want to track freshness
- Store in a cupboard or pantry, ideally between 10–20°C
- Use clean measuring tools when scooping to avoid cross-contamination
📦 Bulk Buyers: How to Store Multiple Bottles
If you’re stocking up for school events, summer holidays, or parties, here are a few extra tips:
- Store unopened bottles in their original packaging or boxes
- Avoid stacking bottles too tightly – air circulation helps prevent condensation
- Rotate flavours – use older stock first (first in, first out)
- Keep a spare funnel and measuring jug nearby to avoid contamination across bottles
Remember: all our bottles are fully recyclable, so once you’re done, pop them in the appropriate recycling bin.
💡 How to Tell If Slush Syrup Has Gone Off
It’s rare, but here’s what to look for:
- A noticeable change in smell
- Separation or cloudiness (some mild settling is normal – shake well before use)
- Mould or unusual residue near the cap
- A sour or off taste when diluted (test a small batch if unsure)
If in doubt, it’s best to discard and replace. But with proper storage, your syrup should last easily through its shelf life.
🧪 Bonus Tip: Pre-Chill for Better Slush
For the best results with your Ninja Slushie Machine, try pre-chilling your syrup (and water) in the fridge before mixing. This reduces freezing time and results in a smoother texture.
Just follow the standard instructions:
- 150ml base mix
- 100ml syrup
- Water to max fill level
- Blend and enjoy!
