Any variety of Potato can be a New or Old Potato. There is no variety called New or Old. New Potatoes are harvested earlier, so they are smaller than Old Potatoes that are more mature. New Potatoes have less starch than Old Potatoes. An added bit of trivia. If you can't find Idaho Potatoes anymore, it's because they go by their true name, Russet, which were originally grown in Idaho.
