They may very well be from last season !!!
They could be up to 3 years old as proper storage and gas can keep them that long. I suppose they could have been picked green and gassed to change color but they were not ripe like they do to tomatoes.
I thought of that too...but this is the first time I’ve ever had this experience. All these different varieties- you’d think one of them would have a little flavor.
Next year I’ll have my friend in Vermont mail me some fresh ones!
