Nothing personal, but this does not look like a Porter recipe to me at all. Porters are actually a very simple blend of a base malt (I like Maris otter) and some Brown Malt some Caramel Malt (I like caramel 60L) and some Chocolate Malt. Further, my opinion is you’re using way too many added flavorings. There’s nothing wrong with adding flavorings to a Porter. But the vanilla, chocolate and raspberry is over the top.
I like to add vanilla to my Porters. However, I add 5 beans to the secondary. That said, if you use too much Brown malt the roasted flavor of the Brown Malt will hide the flavor of the vanilla. I also recommend using a very high quality vanilla bean; don’t go cheep with this ingredient. It won’t pay.
Porters happen to be one of my favorite brews. If you enjoy a good Porter, I highly recommend reading the book titled: Porters and Stouts, by Terry Foster. Great book, lots of valuable information related to your recipe.
Good luck!
