Due to the large variations of Celeste and BT trees, it can be very difficult to tell them apart based on only a few characteristics, which by themselves are not definitive. If you look up the F4F site on Celeste and BT, you will find a lot of "accessions" under their names. Maybe some of them are mislabeled and got mixed in. It can be confusing. One of the characteristics of BT is that its fruits has that pinkish/reddish eye when unripe but not in Celeste fruits. However, I do not know if this covers all the "accessions" for these two varieties. The Celeste figs I tasted (my neighbor's and mine) tasted similar but I'd not think they taste like sugar or honey. They do not have cavity in the center (some BT accessions do not have it either)....Most Celeste figs are not large, but that can be debatable as well.
