If you want to add them to primary, that's fine but be sure the beer is already at FG and has cleared. Vanilla can over power a beer in a pretty short time so if you are one of those folks that always leaves beer in primary for 3 weeks or so, be sure to add them towards the end. 3 weeks of vanilla beans can easily become a vanilla bomb!
I prepare them the same way Hello does but with cheap vodka that I don't drink![]()
My aunt makes homemade bottled vanilla to use in baking. And she uses rum as the base. She has used rum and vodka before and the rum makes a better version in my opinion. If I was to add vanilla to a beer I would soak it in rum first rather than vodka because of this.
and FWIW, if you have a Costco/Sams club buy your beans there.
I think you get 10 beans from Madagascar for like $20. Where as if you go to a grocery store your paying like $10 for one or two.
Does she use dark or light rum? Most light spirits are little more than neutral spirits directly from the distllation process with little to no age.
I'm still pretty new to homebrewing, but am considering a vanilla porter for the winter. Are you guys pitching the vodka as well as the beans into the fermenter or just the beans in the fermenter and the vodka in you?
