I have a collection of red apples, not really crimson, more deep scarlet in my new orchard. The majority are 'Red' versions of classic varieties, so Red Alkemene, Red Beauty of Bath, Red Ellison, Red Fortune, Red Melba, Red Miller, Red Norfolk Royal, Red Peasgood Nonsuch, Red Windsor. Also Red Delicious and Redsleeves, plus a couple of more ornamental, red flowered and leaved trees, Pixirosso and Redlove Circe. A few more were beautifully bright red coloured this year - Opalescent, Queen Alex and Queening, Pearl and Queen Cox. And for cider, Kingston Black is deep crimson.
