lactofermented sweet potato smells like wine

I mashed some cooked sweet potato with yogurt whey and salt. I covered it with a towel and let it ferment for nearly three days. I was expecting a sour smell but it smells like alcohol...Do you think its safe to eat?

I love my kefir grains; they're my 100 billion children. :) :) I'm glad you're having fun with it, Nance!

I just ordered water kefir grains and I'm having great fun watching the process on my counter! Getting bubbles now and lemon's floating on the surface.

That is unless you want alcohol potatoes :)

If you have an alcoholic smell then you may have yeast fermenting it rather than the normal lactic acid bacteria that produce the sourness. It may need more salt next time to prevent the growth of the yeast.

No reason you can't get some alcohol when you are fermenting food that contains sugars.

Did you follow a recipe or just throw it together? It smells like alcohol because the sugars fermented, but I lacto-fermented some apple chutney a few weeks ago and that went to the normal sour smell. I'd say taste it, wait a while, see how you feel. The worst that'll happen is that you'd throw up, right?

It's normal for fermentation to create some alcohol. Kefir, a lacto-fermented product, naturally has a tiny bit of alcohol in it (like less than 1%, though up to 2%).

If you can smell it that strongly, though, you've got something closer to salty sweet potato wine there. How's it taste?

I make fermented sweet potatoes, too, with yams though. Instead of whey, I added some coconut kefir and Himalayan salt. Also poured some kombucha. Left it out for 2 days. Tastes spicy, tart. It's in the fridge now, being chilled. More tasting is needed to see if this one is up my alley. But so far, no complaints.
