That’s why I asked if it was handy. I have never heard of the two you mentioned but I googled them.

The Mutsu (陸奥, ムツ) apple (also known as Crispin) was introduced in 1949 and is a cross between the 'Golden Delicious' and the 'Indo' apple cultivars first grown in Aomori Prefecture, Japan.

Winesap is a well-known American heirloom apple, and was a major commercial variety in Virginia during the 19th century. Its origins are unknown but it probably dates back to the 18th century. It has all the qualities needed for commercial production - it is a regular heavy cropping tree with very little biennial tendency, and the apples can be kept in natural cold storage for a good 3 months or more. It can be eaten fresh but is primarily a culinary apple, also popular for juice/cider production.

I think we had a winesap tree in the yard of the parsonage where I lived when I was 6-8 years old. It matches the description. We used to make pies, Brown Betty and apple sauce from it until it was damaged in a rainstorm. The congregation came out to help cut it down and convert it to cider, apple butter and firewood.

I was thinking the same thing!!
