Bb89,stone fruit flavors compliment apples very well.My personal favorite is apricot-apple or apple-apricot cider. I know there are lots of natural flavorings available to be used when brewing or cidering, but Brew Craft is my hands down favorite for apricot flavoring. To me, many of the others flavoring brands may smell like apricots, but they don't taste like apricots in solution. After bottling (if much time passes) the strength of both the apple and the apricot flavors will increase; maybe not much difference between one day and one month, but between one month and six months the flavors definitely improve.
Wyeast Sweet Mead Yeast (4184) makes fantastic hard cider, apple wine, ice cider and applejack too. When fermented at less than 60*F, 4184 throws off apricot, peach, and other stone fruit flavors when using pure apple must. 4184 is now the only yeast I use for apple-based beverages.
