Even the Romans knew that there is no disputing tastes.......... they are subjective. Howsomever, that is not the end of that story, tastes do change and in my opinion can be trained (i.e. improved) to some degree. We dispute about tastes here all the time. Somewhere in the background is the notion, however farfetched, however selfish, that if you but knew what I do, you would like what I like. And, of course, that is tautologically true because if you knew what I know, you might as well be me, or at least a reasonable facsimile of me.
But you ain't.
Still, a fascinating aspect of the 'taste is subjective' question is that just as much as we are trying to justify our own taste, we are trying to find the commonality with each other's taste. Seems to be in our being to do that. We try to use a shared bourbon language, (sweet, rich, spicy, hot, dry, vanilla, syrup, leather, etc. etc.) to overcome our subjectivity.
All of which brings me to my point. Don't allow subjectivity to mean very much........... look to credit the palates of others, look to learn.
