One of them was ripe so I cut it. It was super sweet.
My taste buds are very sensitive to sweet since I am more into non sweet chocolate and got used to it.
I am surprised that Keit mango is not only gigantic but also taste so good. Why don't people rave about it?
I'm a fan, but there are other varieties that many prefer.
The lemony musk that Keitt is not something you find in the newer, more widely hyped mangoes, and the shelf life of Keitt is also not common.
If you try some of the newer, less nuanced, more candy sweet intense ones, you'll see why. A candy-like fruit really draws people in, but I'm right there with you, some subtlety and nuance goes a lot further with me.
You may enjoy Maha Chanok. It's not as sweet as the newer types, but it has more subtlety, and when grown in SoCal, some of the fruit are excellent and have parsnip and durio flavors. It can also produce multiple crops like Keitt.
That said, it's a mono type, so you will want to graft it to established rootstock, which is a game for the most patient, 4-7 year wait time.
