DavidP17 Posted August 8, 2011 Share Posted August 8, 2011 Iv got a fruit salad ale in the fermenter at the moment and i just had a taste while taking an SG reading It tasted and smelled great when i tried it abuot 4 days into fermentation but now it has a kind of a sharp, vinegar like aftertaste and smell. (8 days in fermenter) has been fermenting at 20 degrees pitched at 24. Will this come and go or is this batch ruined? Link to comment Share on other sites More sharing options...
PB2 Posted August 8, 2011 Share Posted August 8, 2011 If it is vinegar, it will only get worse. [pinched] Link to comment Share on other sites More sharing options...
DavidP17 Posted August 8, 2011 Author Share Posted August 8, 2011 Noooo... Is it an infection/Do you know what could have caused it? Link to comment Share on other sites More sharing options...
Matty A Posted August 8, 2011 Share Posted August 8, 2011 If it does taste like vinegar it does sound like an infection. Does it also smell bad. Link to comment Share on other sites More sharing options...

PB2 Posted August 8, 2011 Share Posted August 8, 2011 Acetobacter converts the ethanol to acetic acid. Cut-and-paste from our FAQs: Comment - from time to time a Brewer may experience an infected brew. Fact - all non-commercial beer carries some level of infection. Fortunately, infection is only apparent once the off flavours and aromas reach a certain threshold (perceivable level). Some of us are more sensitive to this than others. An infected brew may produce the following symptoms: 1.Appearance; a scum ring inside the bottle and haziness (not due to yeast) 2.Aroma; vinegar, medicinal or solvent smell. 3.Taste; sour, sharp or harsh flavour. Remedy - clean and sanitise all equipment that will come in contact with the brew to minimise the symptoms of infection. The persitent krausen may have been a clue to the brew becoming spoiled.

DavidP17 Posted August 8, 2011 Author Share Posted August 8, 2011 Dang.. Cheers Paul ill give it a few more days in the fermenter i know its most likely ruined im just curious to see if it gets worse Is this most likely from something not being clean in my fermenter? the weird thing is it smelled and tasted great when it was about 5 days into fermentation Link to comment Share on other sites More sharing options...
PB2 Posted August 8, 2011 Share Posted August 8, 2011 Acetobacter works on the ethanol so it tends to take hold toward the end of fermentation. Yes, it could be cleaning/sanitation and/or airborne. Link to comment Share on other sites More sharing options...
weggl Posted August 8, 2011 Share Posted August 8, 2011 The tree lopper bloke I made a batch or Wipper Snipper for had a bottle that had gone to almost pure vinegar, I found the problem it was a bottle cap wich had no seal. The beer had oxidised. Warren Link to comment Share on other sites More sharing options...
Matty A Posted August 8, 2011 Share Posted August 8, 2011 I thought it would taste more like wet cardboard rather ther vinegar. Maybe the lack of a seal allowed the airborne bug to get in which infected the brew. Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2011 Share Posted August 8, 2011 I thought it would taste more like wet cardboard rather ther vinegar. Maybe the lack of a seal allowed the airborne bug to get in which infected the brew. I doubt an airborn bug Matty as I believe they tend to float around with the breeze (or no breeze) they can not float down under the lid then up to the top of the screw and around to work their way into the bottle. An oxidized beer can taste like sherry, wet cardboard, lipstick, butter, popcorn, metalic, honey etc. No need to worry when you drink it as nothing that can grow in your beer can hurt a human. However, you may end up crapping through the eye of a needle [crying] Link to comment Share on other sites More sharing options...

The lipstick taste comes from the glasses the girls drink that Mexican stuff from[pinched] Link to comment Share on other sites More sharing options...
