I believe it refers to a higher measured brix.
I have grown both ambrosia gold and ambrosia red. Both early, sweet and productive in my garden. I enjoyed them.
In the case of Ambrosia gold, I believe the seed I had through a trade was not quite stable.
I used it as the mother to breed the KARMA cherries and the result was 2 colours in the F1.
This turned out to be a huge bonus although unplanned.
