RubyFrost apples are deep and rich with a hearty crunch and ideal, crisp texture. Developed at Cornell University in New York, RubyFrost® is one of the few variety apples available fresh in the winter months, as well as a superb baking apple thanks to its plump, luscious size. Being an outcome of a natural cross pollination of Braeburn and Autumn Crisp varieties, these apples are an excellent source of Vitamin C.
