It seems like it would be hard to find a bottle of whisky that was 'corked' because the liquid and the cork don't touch, unlike with wine where they recommend maintaining contact at all times.
But, even with wine, there is a growing amount of research into the value of cork. I recently read an article about Penfolds, one of Australia's biggest wine makers, having been testing screwtops on even very high-end, meant to be aged, wines for the past decade or so. They've bottled some of their Grange ($200 +) line with screwtops (for internal research purposes only) and have been tasting them side-by-side with cork-sealed versions. They found 1) that the wine was aging well with both closures, but 2) more importantly, the wine with screwcaps was more consistent over time. That is, after say 10 years, the cork-sealed bottles, when opened, had a wide variety of quality/taste/readiness, while the ones with screwtops were pretty much the same.
Wine afficionados can argue over whether consistency is a good or bad thing, but what the winery said is that it would allow them to better predict when the wines should be at their peak.
