I am having constant problems with Carling, mainly Carling where the taste is horrible and it has a bad smell. Happens about two or three pints in ever dozen pints. I know its nothing to do with the glasses. Have and still having tec services out they say its one thing then another and can’t resolve the problem last one was the the pipe going to the remote cooler was too long so they shortened it by 7in before that the coil was supposed to be blocked and they changed it but they didn’t there are to many reasons to mention here what tec services say. Tec services said they have inspected the pythons coolers coils and everything else and says there’s nothing wrong so was wondering if any one else had any experience with this. The cellar remote cooler and all pipe work is around 17 years old. I do apologise for the long post.
