I poured my pindo palm fruit vinegar experiment into a glass today. It has spent 4 months gently bubbling away and finally all the stuff on top sank to the bottom so it was time to see what it tasted like.

If the smell was anything to go by, it probably tasted like about a THOUSAND PROOF liquor! Shocked

Being afraid of getting my pigs drunk it all went down the sink, way too many alcaholics in my gene pool to even taste the stuff.

And the smell coming out of the cooler with the washed honeycomb would make a monk VERY happy.

Seems like I missed out on the jelly setting gift but got double helpings of ferment the danged stuff instead. laughy

not even a tiny sip?

Only half way there, GB

If you are trying to make vinegar, first step the yeasts (which are anaerobes) convert the sugars to alcohol. Second step, the vinegar molds (aerobes) convert the alcohol to vinegar. You said "when bubbling stopped" but bubbles you get when organisms living below the surface are releasing gasses (in this case the yeasts releasing carbon dioxide as they oxidize sugar to alcohol). No bubbling as the vinegar molds oxidize the alcohol to acetic acid since being aerobes they have to live on the surface.

Not even a tiny sip! It smelt so good, you see Shocked

scared me it did! The smell of rum and brandy and bourbon make me sick to my stomach but this stuff smelled fruity and rich and yummy.

After I poured it down the drain I suddenly realized that my pigs might move easier if I got them drunk Laughing

Mike, it made a thick mat of greyish mouldy stuff that finally sank to the bottom and only a thin skim of something and a tiny patch of mold were still on the top. But as I only had a two liter bottle with a paper towel wrapped around the mouth it had been steadily evaporating so was only about half the starting volume.

A good try and I WILL do it again, if the vinegar is half as good as the other stuff smelled it will be a great addition to salads!

Evaporation not a direct problem in the sense that while the water will evaporate the acetic acid won't. Vinegar is usually a 5% solution.

But excessive evaporation might be a problem with the acid concentration becoming too high for the mold while there is still alcohol left behind. It is, after all, their waste product. Except I'd expect the alcohol to be evaporating faster than the water. Not only does it have a higher "partial pressure" than water but there would be little alcohol vapor compared to water vapor in the air above the container.

Try again. You might want to bone up on how to test for the acid (what percent do you have). High school chemistry, not "rocket science".
