Greets All/Luis Luis, you mention a honey which foamed on conatact with whatever it was being poured into/onto. If the honey fermented in a closed bottle it would have become saturated with carbon dioxide gas - similar to carbonated coke or juices. When you remove the cap and pour it the carbon dioxide comes out of solution in the water which is now under lower pressure and forms little bubbles. This is just the same as when one pours coke, champaigne etc into a glass and it foams over. The cause of the fermentation is probably a bacteria with a high sugar tolerance - if you ate the honey you may be able to geuss what it is by the symptoms of the resulting food poisoning - but that's the difficult route. I would throw it away - down the toilet.
