Whiskey brands and their stoppers...

Okay - i do not, myself, drink whiskey, and the only real knowledge i have of the drink comes from the bottles of Jack Daniels my SO occasionally buys. So - my question is, is there a brand of whiskey - or several brands? - that have/use a cork stopper rather than a twist cap? And if so, is it/are they available in the US?

Thanks!

ETA: I think i've got enough examples now, thanks everybody!
