RIS Recipe Critique

[jnacey]

Hey guys,

I'm throwing together a recipe for an RIS that has a ton of coffee flavor and more of an oatmeal stout type base. It has a ton of different ingredients right now based on different flavors that I'm looking for and I'd like some feedback from you guys to see if all of these are needed. Let me know what you think.

I've been thinking about dropping the Patent to .5#, and bringing the roasted barley to 1.5# and chocolate malt to 1# and maybe adding a touch of Special B.

Any thoughts?

 

[progmac]

it has an awful lot of non-fermentables. what is your target FG?

 

[jnacey]

It's at 1.026 per beersmith.

It's at 1.026 per beersmith.

That number is going to be the same regardless of what you use in your grainbill or how you mash. Feel free to ignore it.

You do have 79%, by weight, of highly fermentable stuff going in your wort, so I wouldn't be worried about that. That's roughly 10% roast and 10% crystal - pretty standard for an RIS.
