In my experience so far my trees fruited consistently over the entire tree but we still dont have years of information documented about the pear yet. What you noticed as far as the flavor of the skin is similar to the flavor of ayers skin from the same Tennessee breeding program. My understanding is the same pears were crossed to make ayers that was used with Tenn. The results are consistent. Additional information is documented here Question the History of a pear or know some history? Post it here! - #79 by clarkinks
See PearSpecies
“Originated from a ‘Garber’ X ‘Anjou’ cross made in 1937. Because ‘Garber’ is thought to be a P. pyrifolia X P. communis hybrid, ‘Ayres’ is one quarter Asian pear and three-quarters European.”
It was named in honor of Dr. Brown Ayres
