Hi Gene, I have to clarify that it is my first crop of Longue d'Aout, so I am not an expert with it, and taste is a personal thing. Taking into account the previous, so far, the Longue 'Aout I have eaten have been very sweet (not a "honey" fig but very sweet) and good taste, above average.
According to P. Baud, Longue 'Aout is a good tasting fig but it suffers specially a quality decreasing when it is planted in soils with deficient drainage or waterlogged. it seems to be a variety specially prone to this. Ironically, the fruit bears well the rain.
In conclusion, Longue 'Aout is for me an advisable variety, good tasting and productive. It is not an outstanding variety, in my opinion "outstanding" are only a few varieties.
I am referring to main crop fig, I haven't tasted the breva crop yet. I have heard that the Longue 'Aout breva is not so good.
I have to add one thing, my Longue 'Aout is grafted on an adult tree of a local variety. Maybe in this case the problems with wet soils disappear, who knows! Contrary to apples and grapes, the influence of rootstocks on figs has not been investigated so far.
