My son wanted a vanilla porter. Not one with a hint of vanilla but a hit you in the face vanilla ( I think it is gonna be over whelming) Anyway we made a robust porter that I had made a few times prior and added 1.75 oz pure vanilla extract at 10 mins of the boil. Then we soaked 2 scraped and chopped vanilla beans to a small amount of spiced rum and let that soak for a couple weeks. Racked the porter to a secondary and strained the vanilla rum into it. let that set a week and cold crashed and bottled it tonight. The 2 year old grandson had to set with me and " help papaw bottle beer" ... The sample was not as bad as I expected but I have a feeling it is gonna be rough.
