We have a bottle of elderflower liqueur, similar to St. Germain’s, and the outside is incredibly sticky. It wasn’t sticky when I bought it, and I’ve actually washed the outside once and it’s still sticky.
We haven’t spilled any on the outside of the bottle - I mean, maybe a drop or two, but the bottle is sticky ALL OVER.
We’ve kept it corked / closed when not in use.
Is the liqueur somehow climbing out of the bottle and evaporating, leaving sugar behind?
Is it a bottle that’s colored glass? Is it possible there’s a color applied to the outside that has gotten sticky? Has the bottle been stored in other than cool and dry conditions?
The bottle is clear, and has only been stored in reasonably cool and dry conditions. Worth noting that this isn’t happening with any of the other liquor bottles in the same cabinet - it’s this bottle and this bottle only. I suspect it has something to do with it being a sugary liqueur, as opposed to the rums, vodkas, and gins that otherwise occupy the cabinet, but I’m convinced we haven’t spilled to the extent that the bottle is sticky.
Has the bottle always been stored in a normal, upright position? Unless you’ve got liquid helium in there, I don’t see how it’s possible for the liquid to migrate up the bottle to the opening, regardless of how well it’s corked.
This is like a lateral thinking puzzle! My guess is that an octopus from a nearby aquarium squeezes out of his cage every night and goes in search of shrimps, and on his route passes through your kitchen and brushes against the elderflower liqueur bottle. But he returns to his cage by morning so no one’s any the wiser.
The bottle has always been stored upright (well, at least since it entered my possession after buying it at the liquor store). I know nothing spilled on it because, well, it’s in the liquor cabinet and nothing has been spilled in the liquor cabinet.
It does sound like a lateral thinking puzzle.
I will go wash the bottle again with water so it isn’t sticky and report back if I notice it being sticky again.
As a serious suggestion, is it possible the soap eliminates the stickiness only temporarily (by coating it with soap film) but then that soap film evaporates, leaving the sticky surface exposed again?
Wait, never mind, you said you’ll wash it with water.
My guess would be that the cork/seal isn’t 100% and that a tiny bit of liqueur evaporated and then condensed into a few drops that ran down the outside of the bottle.
I’ve had a possibly related experience with a plastic bottle of “natural” plant-oil based insecticide that developed mysterious stickiness/drops on the outside of the bottle.
Cheap vodka has the benefit of being easily available (many people are still having problems finding rubbing alcohol) and non-toxic, so better for being near something which will be imbibed.
Another possibility would be to just put the liqueur in another bottle.
I’m going to wager that this is it - there’s some evaporation from a not-tight seal that then condenses. Looking closer, I can see droplets on the “label” nearest the neck. Also, the bottle does not have a screw-top, but rather a cork attached to a plastic top - more of a “stopper” than anything, and I bet it’s not a tight seal.
And to another comment, I am slowly moving the liqueur from its current container into a new container, but I get a headache if I try to move too much of it at a time.
Something like that makes sense. So does some kind of coating which has turned sticky over time. Or someone else has been in the liquor cabinet that the OP does not know about.
I’d put my money on some getting on the label and not being completely rinsed out, and then migrating from the wet/damp label onto the rest of the bottle.
