@Ruben: No problem! Here’s a link to what seems to be the most recent update:
@HerbTarlek: In Apples of North America, Tom Burford notes that Jefferson “repeatedly planted Esopus Spitzenburg at his Monticello fruity but never succeeded with making it a productive variety.” Burford reports that in warmer regions it is highly susceptible to fireblight and moderately susceptible to scab, canker, and collar rot, and also prone to Jonathan spot. Cummins Nursery in New York simply says that it is “susceptible to just about all the common diseases.”
However, Fedco says that it “vastly prefers New York and New England to Virginia,” and @alan grows it successfully in his part of New York, and speaks very highly of it. I don’t know whether anyone here can speak to their experience growing it in the Upper Midwest, but it seems like it would be likely to do better there than it would in the South.
Here’s a link to Burford’s description:
