I was intrigued originally by descriptions of Autumn Sweet as a new extra sweet E. plum variety, although this species tends to get exceptionally high brix from older varieties such as Castleton, Empress and Valor- up to 24% brix. It is not proving to be an easy variety and may be particularly vulnerable to cracking on wet seasons and is an upright grower- slow to bare.
In flavor and texture it is exceptional, though, because it shares some of the pluot ability to get high sugar while still quite firm. I’m not sure it’s sweetness is exceptional as a soft ripe plum but it is a treat to eat it crisp. Enough tartness to add zip and the texture is unique in an edible (or should I say sweet?) E. plum.
