I wouldn’t even give it a single star, it was absolutely rubbish. It took about two weeks for it to drop a mild at 3.1% ABV to 2.0% ABV and even then it produced a horrible chlorophenol (TCP) smell and taste. In the end I poured in boiling water to try and get rid of it and added Mangrove Jacks and the brew finished fermenting in about two days. Couldn’t be more disappointed I though, until I tried their Bohemian Melody lager yeast!! Will never buy their products again!

Hi Richard,
I think it may well be possible that this is not a yeast problem but possibly something in your process. TCP type flavours are caused either by infection or by some form of chlorine in either the water used or cleaning products. This type of infection can also cause fermentation issues. Pouring boiling water in unfortunately will not help at that stage. At The Malt Miller we are always open to a phone conversation if you are not 100% sure of how to use a product or process. If you would like to discuss further please contact and speak with Rob, Martin or Nic.
