I've been brewing over 30 years and can only remember dumping 3 batches.
The first was when I went to add Polyclar and grabbed the wrong container and added a cleaner. I realized right away what I had done and no one drank any.
The second was a club barrel project. It soured in the barrel. It was interesting, but not really that good.
The third was a batch a neighbor asked me to brew and then, for medical reasons, she couldn't drink it. It was fine, but not what I like. So, after a while I got tired of having it my kegerator so I dumped it.
