Mike,
I had a big question mark on mine and rightfully so because of the way it looked.
I was told by a few theirs did the same as mine did at one time or another. I even asked another friends who I sent a large air layer of and he said the figs were large and dark.
Yours however, I am 99.9% certain you have the real deal. Has the looks and size of a Genovese.
The leaves I've seen were very close to one.
As for the taste, I think it may have to do with its' age.
BTW,
Is this the breba? looks like the breba to me. The main crop is smaller.
