Luckily, or perhaps sadly, there was not much to doubt here - I simply cannot imagine that Keller, or anyone, really, could make a wine taste so dreadful. In that sense it was an easy case. As you say, it is much harder if you are just not sure, when you want to be fair to a wine you have never tasted before. Sadly, I do not have a simple answer. Even screw caps do not help if the wine has been stored badly. So the only way forward seems to drink more and get better at it (spotting faulty wine, not the drinking I mean, or do I?).
