Its been a LONG time since i've done a porter, and i can't find my original recipe. So, doing some research looking at difference recipes, i developed my own. I tend to like porters are the darker side, with some good hop notes to them. How does this look for a 5 gallon recipe?

*NOTE* I was planning on doing 4 versions of this

1) Basic
2) Substitude 2 lbs base malt, for 2 lbs smoked malt (not peat malt)
3) Basic + Vanilla (I have home made vanilla extract being made)
4) Basic + Vanilla, oak and bourbon


What do you think? Would this recipe do ok with all the versions I'm thinking of doing?

Cheers!
