    Hallo, I have a beer which has been sitting in second fermentation vessel for about two weeks. It has a bad taste noticeable as well as all the good taste coming from hops and malt. Theoretically I suppose the alcohol might kill the germs but perhaps this is impossible since ABV is only about 4%.
    I was thinking of taking the beer out of the container and boiling it before returning to it. I am aware this may kill live yeast ( whose presence is the very definition of real ale) but might kill germs too. I suppose I might end up with a bottled-if-not –conditioned ale. Might at least become uncontaminated and hence drinkable. Has anyone else found a way to deal with contaminated ale?

    So frustrating after sterilising everything and boiling wort.

    Boiling may kill the bacteria but may not remove the bad taste. Also you will probably boil off all the alcohol.

    Then what is the solution? More sterilising and boiling of wort?

    Can you describe the "bad" taste in a bit more detail? Eg-apples,corn,cardboard,TCP,astringent.

    By boiling the whole lot you will sterilise your bad tasting beer, but my guess it will still taste bad. By boiling you will kill the yeast. If you then prime and bottle it it won't secondary ferment and so won't carbonate.

    Are you sure the bad flavour is a true sign of it being infected? As big Jim said if you can identify the taste it might give a clue as to what has gone on/wrong.

    If it tastes bad now, one of two things will happen if you bottle it:

    1) It really is an infection and it'll likely get worse
    2) It's not an infection, just some off flavour and it *may* get better with time

    Either way, making it better is the last thing that boiling fermented beer is going to do.

    I agree with C I would get it bottled and leave it. If it is infected you will know about it. SOme of my best beers were terrible to begin with but 3-4 months in the bottle see's improvemnet and 6 months they were sublime. :thumb: :thumb:

    You will usually know it is infected by some form of growth on the surface. :thumb:

    Well I'm not much into bottling. I suppose I could leave it in the keg for a couple of months and see if it improves.

    Now that the cooler weather is approaching I intend to start brewing again.

    Hello,
    Hope you folks remember me. I haven’t done any home brewing in a long time but hope to get some done before Christmas.

    I believe my last posting dealt with off-flavours. I believed my sterilisation had not worked properly so I was left with a bad taste.

    I recently spoke to a Brewster in a brewery. She told me that temperature may be responsible for off taste. I placed wort in primary fermentation vessel in kitchen whose temp was about 20 C. She said this would mean temp in pfv would have been about 30 C which would definitely create bad flavours.
    The only alternative place I have to brew is my garage which is about 10 C. My Brewster said fermentation here would take much longer.
    So is this the solution or not?
    How much longer would it take? What temp should wort be? Should I do like Craig Faraway and buy a heat belt?

    Thanks in advance

    temperature to ferment at depends on beer type. lagers - lower temps - ales 19-21 and some others higher again.
