It tastes pretty interesting, not really better than regular cider (though Magner's not really my favorite cider to begin with) but certainly a bit different. I'll have to try it again with Hornsby's sweeter cider makes any difference.
I still want to try one of the "hardcore" ciders that's fermented to 40 proof or something insane line that though.
Edit: Okay, a little searching has revealed two things. One, that i could just freeze distill a bottle of cider myself, and two, that such a beverage is often referred to as "applejack" and BevMo theoretically has some! I may have to investigate one or both possibilities :)
