Yeah, you never know what aging can do, I do have one that was so tannic and bitter I'd reflexively spit it out every time I'd try a sip, but it's getting better with age. Going on six years in the carboy, but though it's not yet pleasant, it's drinkable. So maybe six more years and it will taste as good as it smells!
