Do these have a similar taste profile like the Col de Dam varieties? I'm trying to figure out if it's worth growing both. I know the fruit themselves are different colors as you can see in the two threads below (One being gray & the other black). Does anyone have any experience with these?

I am growing Noire.  It is the biggest tree I have.  Two year old tree with one season in ground and has a trunk almost 3 inches in diameter.  

I left 6-7 figs on, 3 haven't ripened, 3 ripened in late October during our flood 12+ inches in a couple days after no rain all summer, all 3 split badly.

Of those figs, one was less split, I could definitely taste its potential, even though they weren't completely ripe, beautiful fig to look at in my opinion  
     

Looks awsome don. Almost looks like a 258 in the inside. You know what they say.. its whats in the inside that counts !!!! I have a bourjasotte cutting that has grown nicly. No fruit. Still young. I dont know if its a gris or noir.

Noire is delicious when really ripe. Mine grows vigerous in Fresno. No fmv either.

Yeah, many people have said they are both exceptional varieties. Any info on Gris & if Noire is similar?

I haven't seen any direct comparisons between BG and BN and haven't thought much on it. Based purely on my memory of fruit photos, I doubt their relationship is the same as CdD Gris, Noir and Blanc. I have both, though BN is only two years old and produced one fig for me while BG is four and has produced the past two seasons, prolifically this year. My sample size is small and I wasn't directly comparing, but what I have seen confirms my feelings about them not being sports of each other. Take this with a grain of salt, of course.

I notice that none of the well know French fig websites sell BG. I do see it is well known in England, but then, the fruit looks a bit different than the California version.

CdDN began to show wrinkling signs around the stem and was soft. Bourjassotte Grise was soft. So I finally picked them.
Both had a sweet berry taste but the BG's flavor was more watered down and juicy. BG is a first year tree so it's probably not really fair to compare it to the three year old CdDN. The CdDN was more concentrated, dryer and significantly sweeter than the BG. I had been eating some Adriatic JH figs right before them and could taste the slight “Bordeaux berry” under taste to the CdDN that hinted of a Bordeaux wine. It was different from the “Adriatic berry” taste of the Adriatic JH and BG which were berry tasting but didn’t have that added flavor. I usually don’t taste a lot of difference in figs but CdDN and Adriatic JH (half the size of BG) were outstanding in their flavor class. All were delicious!
