[Where did you get the "NDM#4" that you tasted and where did you get the Sia Thong? There are many variables that can effect the taste.]
I bought 4 NDM#4 trees from Zill, 2 NDM#4 trees from Pine Island, 4 NDM#4 and 2 Sia Thong trees from Excalibur. I stop by last year to purchase more trees and saw the Sia Thong mango on the counter for sale. For a second I taught it was a large NDM then I ask Linda. The NDM trees from Excalibur in my back yard fruited very heavy last year. That's when I did the side-by-side comparison and taste test. My first taste for the Sia Thong mango. Believe me it is good with all the characteristic and taste of a NDM. The Sia Thong is much bigger with dark yellow to light orange in skin color. The NDM#4 is smaller yellow with slight hint of green skin color. The flesh on the NDM#4 is more orange then the Sia Thong close in color to the flesh of my Maha Chanok.
