US is very snobbish about wine, making marketing of screwcaps difficult; there are several Cabs > USD 100 bottled in California with screwcaps, however. The expensive wines with screwcaps are all from Australia and NZ from what I've seen, in fact everything except Grange is available in screwcap. My expensive bottle was Penfolds Bin 707 1990 (the first year that screwcap was done). Current release cost is about USD 150 and worth it. For current release wines the most expensive screwcap that I've seen is USD 200 and that is in the US (also sold out at the winery, there is no retail distribution). You guys in the wine business should be well versed about this, maybe I should be charging for consultation? In any case I have yet to encounter a screwcap wine that has suffered for it (and that includes no TCA, though of course it can happen).
