Name says it best. I brewed up my first AG batch and I believe I got the Aceto bacteria. THe beer smells and taste like pure vinegar. What can cause this?

I made double and triple sure that my equipment was clean and sanitized properly. I am not so sure now what I could have possibly done any different.

I split a 5 gal kit in to two parts. Part A was brewed and put in a LBK. Batch B was brewed 4 days later and put in a LBK. 3 weeks in the fermenter for batch B and about 3.5 for batch A.

Batch A had a white film floating on top of it and it smelled like lighter fluid. Batch B looked and smelled great. I tasted that one and it tasted great. Bottled it all up as one solid batch (mistake), and now I have pure vinegar in bottles.

Questions? Comments? Suggestions? Any and all are well appreciated good or bad. I'm a big boy. I can take it. I just need to learn so I don't make this happen ever again. I am SERIOUSLY bummed since this was my first AG batch. It is by far, not drinkable.

By that description it sounds like "Batch A" may have had a pelicle infection, not totally uncommon. There is actually a style of beer (that gets aged for many years) that wants that to happen. Mixing them was a mistake (as you said), the second batch would probably have been okay by itself. I've had pelicle a few times and one batch did remind me of the malt vinegar that can be put on batter fried fish.

Clean your fermenter really good.

It looked something like this?

I read about an infection called the "vinegar fly". From what I've seen, it looks more like streaks from a central point; few to no bubbles. Although every infection can look different. But I have read of people siphoning the beer out from under the infection and the beer being ok; though they suggested drinking it fast.

This really sucks to hear...especially for your first All Grain. Best advice, I would toss that LBK...I guess a cleaning and sanitizing would do it well, I would feel better getting a new one.

Sorry Ray, just brew something else up ASAP to replace it. I've had a few not so great batches and a few that might have even been slight infection...it happends.

Hi guys. Thanks for the replies. Yes professor, it looked identical to that pic you posted. And when I say raw vinegar, it literally smells and tastes like raw vinegar.

I actually have pondered tossing the fermenter and getting a new one, but, I will most likely clean the hell out of it and hope for the best. Well, I do that every time I brew! laugh

Yeah Kenny it does suck. I knew when I was mixing the two together how bad I messed up. I was just crossing fingers and hoping for the best. I do plan on brewing again as soon as I possibly can.

Not sure how this could happen to be honest. When I brew, I normally soak my LBKs in oxyclean free for at least 2-3 hours in advance with a real good scrubbing with a soft cloth. Then I sanitize for around 30 minutes normally instead of the normal suggested 10 minutes. Then after all is said and done and I bottle, I clean the kegs real good and soak them with oxyclean free again. So they get washed two times and sanitized once real good per brew.

Oh well, better luck next time eh? Thanks for the input fellas. I appreciate it.

Ray

It does sound like some acetobacter got into your beer somehow. Sorry for your loss, but maybe start eating lots of fish and chips, and taking advantage of your ready supply of malt vinegar! wink

did you open the top at all during those 3 weeks of fermentation?

could be the slightly faulty design of the MrBeer Lid...which works great when fermentation is humming along but after the first or second week a light breeze can easily allow some outside air to enter your LBK.

Sorry for your loss..

Definitely mark that fermenter & spigot. Make notes so you can tell if you have trouble with it in the future.

Nope. Didnt open it at all. I only ever have once opened a lid and that was to dry hop a basic Mr B batch long ago.

I do have the LBK and spigot marked. The LBK I am sure will get used again in the future, but now it just seems it is a good time to get rid of the crappy default spigots. I hate those things.
