Hello
A while ago as I was driving through Italy from Germany on the way to Venice. I was getting tired so I decided to stop in Bolzano Italy, close to Austria. Next morning after a nice German breakfast I went for a walk. There I saw this huge 25-30' fig tree over 50 years old and loaded with these delicious looking large black figs. I was surprised being so high up the mountain.
Bolzano is located in the dolomite mountains. The dolomite mountains are very close to the Italian Alps (home of the 5300 year old iceman oldest human remains ever found).
The Alps are snow covered all year. January average temps for Bolzano are -5.1C(23F) to 5C(41F) in Niagara area I think Jan average minimum is -7C (19F) so similar to Bolzano but I doubt that the dolomites get the occasional bouts of -20'sC (-2F) that we get. My guess is the alps protect the area for anything colder than 0F (-18C).
The fig is medium to large has no stem and when ripe is shiny speckled black, thin skin, amber interior and very sweet. A light jammy taste. The eye is closed but if heavy rain during ripening the eye will open a bit and some splitting. It must be cold hardy but I find it produces more fruit if given a hot location.
Did a little research and since there are many German people in Bolzano. I compared it to a number of german figs that look similar; Bauer, Bursa Siyahi or black bursa, grosse Schwartz. But none of these are identical.
