WTF Fun Fact – Cosmic Crisp

The best Apple ever in my opinion.
Tastes, sweet and tart at the same time. Fresh crisp, dose not brown when cut. Nice looking. Only thing I can’t attest to is how long it last in refrigerator, the 4 I got my hands on didn’t last long. Will definitely purchase again. Am telling everyone I know about it. Maybe in future will be able to get more as trees come in to better production.
