Mash or Grain "Tea"?

Ingredients
1

I’m making an Alt for my German buddy and want it to be as authentic as possible.  It is supposed to get some dark grain for color.  Would you mash it or steep it and add post mash/pre-sparge?  Or something else?  Who’s the Alt expert out there!

For my last alt I cold steeped my Carafa overnight then added it to the end of the boil. It worked quite well.

I’ve done it both ways for an alt and settled on mashing (although I often use Sinamar).  You use so little dark grain that it has virtually no impact on the mash.

I’m thinking:

7# Pilsen Malt
3# Munich
3oz Chocolate or Roasted Barley (1.875% of grain bill)

I don’t have any Black but I could pick up some next week if it makes a difference.

Thoughts?

Mash it all together.
