There are several ciders on the menu at Rose and Crown, but no pear. (I love pear cider too.) The Woodpecker cider at R&C is delicous though, try that as an alternative.
Since your ticker says you'll be there for Food & Wine Festival, keep an eye out for the Apple Ice Wine at one of the kiosks (might be Scandanavia, but I can't find my preview event menu to be sure). It's a very sweet apple cider that we were served with the dessert course, but I think it would be wonderful paired with cheese, too.
