Creme de Cassis

[Lancs Jag Boy]

I've got a bottle that I opened at Christmas for Kir Royales, but how long should I keep it for?

It's in the fridge, but should I have used it sometime ago, or does the alcohol and sugar preserve?

[Tanguero]

Should happily keep for a decade or two... If it goes furry then sling it.

I've had bottles open for 10 years or more and drunk them. The colour mellows a little over time, but it still tasted fine.

[TwigtheWonderkid]

Agreed, if you haven't finished it by 2025, chuck it out.

Just FYI the bottles usually say something about keep in Fridge and consume in three months.

But I've had my bottle for a year or two.
