Frostbite is an unusual apple, smaller than most modern varieties, and with a very different intense sweet flavor.
It is also one of the most cold-hardy of all apple varieties, and can be grown throughout zone 4 and with care in zone 3 (using cold-hardy rootstocks).

Frostbite was developed by the University of Minnesota in 1921, but not trademarked and released until 2008. For most of the intervening period it was relatively unknown outside of the university, where it was referred to simply as MN 447. However it has played a key role in the University of Minnesota's long-term apple breeding program, and contributed its excellent cold-hardiness to several other important varieties - it is a parent of Keepsake and Sweet Sixteen, and grandparent of Honeycrisp.
