Interesting, I've just had a massive Mango year (one of the silver linings of COVID I guess), and these are varietals I haven't seen before. I'll keep a look out for a chance to snag them.

It sounds like a rare variety to find though. Is this the case?

I don't get the sense that those varietals will only grow in Guimaras, but the locals will tell you that it's not just the varietal but also the specific soil, micro-climate, and cultivation methods of the island that makes them special. I have no idea to what extent that's true, but while I've had lots of good mangoes all over the Philippines, the ones from Guimaras were definitely the best.
