Alternatively, if anyone can definitively prove that wines age well under screw cap, that would be even more ideal.
All reports I have seen about aging under synthetic or screw cap closure is that the aging occurs a little more slowly. There is debate as to whether or not a wine benefits from microoxidation during the aging process. Another question to answer is what happens to these types of closures over 20, 30, 50+ years plus. Will they hold up? If not, you may have to recap them, not dissimilar from corks which slowly decompose over the years as well. Haut-Brion experimented with screw tops. The put some of their 1969s under screw cap, the plastic film in the cap cracked, and the wine oxidized, so they abandoned the experiment. Nonetheless, I still cringe when I see those hard rubber stoppers in my bottle, for the many reasons listed above.
