Can Brown Malt Convert Itself?

[mrphillips]

I'm building a partial mash porter recipe, and I'm not sure if modern day Brown Malt has enough diastic power to convert itself.

As always, thank you.

I don't think modern brown malt has the power.
here's some reading for you...

I've only used Crisp's brown malt, and that one is considered a 'roasted malt' by that company and their malt analysis sheet shows 0 for diastatic power.
