I've brewed my first batch (I posted several threads here these past weeks), it now sits in the primary for the 9th days and... well, so far so good (knock on wood). The recipe I'm following, http://www.homebrewtalk.com/f68/none...a-stout-96969/ is calling for 14 days in primary before racking in secondary on top of 2.5 tbsp (which will be, for me, 1.25 because I did a 2.5 gallons batch) of vanilla extract.
However, I'm wondering. Do I have to sanitize this vanilla extract? I mean, do I have to boil it in water before usage, or is it safe to just throw it in secondary on top of which I'll rack the beer?
