Homebrewing - Beer, Mead, Wine, Cider

It's fine. It might be gross or sickly sweet, depending on how long it's been fermenting.

Auto-brewery syndrome is super rare. It's caused by conditions that allow brewing yeast (and other fermenting microbes) to live/thrive in your gut when they shouldn't. Nutritional yeast is also living brewing yeast, though it's dormant and not actively fermenting when eaten. You will get a bunch of B complex vitamins from the yeast!

But beware, my friends used to call green beer 'fartzens,' after the original Hefefartzen that we drank way too early.

Autobrewery syndrome is rare and probably has more to do with your diet and antibiotic use than consuming a few actively fermenting drinks.

Some drinks like pulque are traditionally drunk that way and that's why they can't be shipped long distances. So if its been done by other cultures for thousands if years, I'm not a doctor, but I'm gonna wager its fairly safe.

Lots of drinks can be consumed this way, it is common here to drink wine (sold as "burčák"). So it is mostly ok, but some have diarrhea from it. I would say to don't drink too much of it, it can make some digestive problems but nothing serious.

As the saying here:

• booze dilate veins
• wine spreads legs
• "burčák" spreads your butt

I drink kombucha several times a week and it's still fermenting and haven't had an issue
