Fee Bros cocktails syrups: must I refrigerate after opening?

[MC Slim JB]

I've got a few cocktail syrups taking up space in my fridge. I don't use them all that much; it will take me a while to go through a 750ml bottle of orgeat syrup. I wonder: are syrups like Fee Bros. orgeat and falernum shelf-stable after opening, or do they need to be refrigerated? There's no indication on the bottle.

I have a bottle of Monin Almond syrup that I bought specifically to make Mai Tai's and have not refrigerated it. I have not seen any mold or sediment in the bottle and it tasted fine a few weeks ago (probably been open several months). Monin says it does not require refrigeration after opening. The ingredients on the bottle are cane sugar, water, and natural almond flavor.

I would imagine Fee Brothers contains some preservatives and would be fine in your liquor cabinet.

I've had Monin syrups grow mold before, but only after a farily long time on the shelf. Most bitters contain between 35 and 40% alcohol which makes mold a non-issue, though Fee Brothers doesn't disclose its alcohol content, so there's no way to know for sure if there is enough alcohol to inhibit mold.

Fee syrups contain a preservative, so you should have no issue there. I have a few bottles of French orgeat--all without preservatives--that have been sitting open at room temperature for six or eight months now with no indication of any kind of degradation of quality, mold, etc. So especially with the preservative factor, I think it should be no problem.
