A local farmer here told me they were the worst fireblight magnet. Threatened to ruin his entire business. He scrambled for days to cut them out.
I ate an apple from him years ago that was either Egremont Russet or Pomme Gris. It was amazing. Nutty flavor. Russeted green brown appearance. Dense/ crisp. Hints of pear, coconut, and a balanced sweet-tart flavor with strong but pleasant savory component.
I want to try planting Egremont to solve this mystery, but am frightened to cuz of the blight risk.
I already have Pomme Gris grafted in. Supposed to be similar eating experience, but grower friendly taboot.
