We love cracking open a fresh bottle of Slydog — but what happens if it takes you a little while to finish? Here’s the lowdown on how long spiced rum lasts after opening.

The Quick Answer

Opened spiced rum can easily stay drinkable for 1 to 2 years, sometimes longer — if you store it well.

The alcohol acts as a preservative, so it won’t spoil in the way some other drinks do. But the flavour can change over time, especially if the bottle is often opened and exposed to air.

What Affects How Long Rum Lasts?

• Oxygen: The more air inside the bottle (half-empty bottles, for example), the quicker the flavours fade.

• Light & Heat: Sunlight and high temperatures speed up deterioration.

• Seal: Always tighten the cap after pouring.

Our Top Tips for Longer-Lasting Flavour

• Keep your Slydog in a cool, dark cupboard or drinks cabinet

• Always close the cap tightly

• If the bottle’s less than half full and you’re saving it for months, consider transferring to a smaller bottle to reduce oxygen exposure

Signs It’s Time to Restock

If your Slydog Spiced Rum starts tasting flat or you’ve had it open for over 2 years — it’s probably time to enjoy a new bottle.
