I've noticed that cask strength whisky is getting sort of popular these days. I can't say that I love either of them although I'm a huge fan of both products in their tamer forms. I really appreciate the pungent flavor up front of a cask strength although I find the finish, due to the heat, border-line painful. Moreover, I've been told that adding water to cask strength is to essentially defeat the purpose. So I'm looking for opinions.
