With all due respect to Jack, I have both 'Fairchild' and 'Young.' Overall, 'Young' is way superior to 'Fairchild.'
No offense, and for you all that matters is what you like so I am not attacking you but in general, you are in the extreme minority here.
Also, as Graham was mentioned...I would pass on this one too. It is Julie-like, a seedling from Julie, and the fruit does not live up to the Fairchild/Richard Campbell hype.
The only problem with 'Young' to some, may be its subtle sugar content. So, if the required mango has to have the standard, 'Haden' like, classical sugar content, then I'd recommend to find a variety with all of the perfect quality attributes of the 'Young,' but with the desired sugar content.
Case in Point: 'Young' vs 'Fairchild'
Taste: 'Fairchild' has just a notch higher sugar content (then it's down hill from here)
Seed: 'Fairchild' has a noticeable thicker seed. The 'Young' has a thin seed, and when I say thin, I mean 'thin.'
Size: 'Fairchild' is a smallish sized mango. 'Young' is a solid medium sized mango.
Flesh: Since 'Fairchild' is a smallish mango with a somewhat thick seed, the flesh content in the 'Fairchild' is much less than 'Young.'Fiber-content: 'Fairchild' & 'Young' are both fiberless.
Anthracnose-disease-resistance: Very Good for both,
Tree: My 'Fairchild' tree is growing at quite a fast clip. The 'Young' is growing noticeably slower., it reminds me of the 'Carrie' tree.
Summary:
The first time I tasted 'Young,' the first thing I noticed was the subtle sugar content. Having grown up with average sugar content mango varieties like 'Haden,' 'Keitt,' ... I noticed the drastic contrast of the 'Young' being a mango with perfect characteristics, as mentioned above, but with a subtle sugar content. Then, I decided to do try something out, in the course of 2-3 years, I've notices that members of my family just love this mango. As I mentioned in the Mango Reviews Thread, we've been giving away large quantities of different variety mangos this year, and the overall noticeable favorite is the 'Young.' Finally, I gave it the King Solomon test. I told members of my family that I wanted to cut down the 'Young' and replace it with the recently purchased, heavenly food of the gods, the 'Lemon-Zest' mango, and well, the response I got back made me feel like some kind of really unpopular heretic.
Hope this helps.
