I'm fermenting a 5.5% Porter, it's on its 10th day and no longer has any activity. I want to add vanilla and coffee to it. I'm using 60g of coffee to brew about 1L of coldbrew minutes the few ml absorbed by the coffee. I will also be adding two (2) vanilla beans split and chopped. My questions are the following: 1. How do I sanitize coldbrew? - Should I boil water and wait for it to come to room temp then use it for the cold brew? Make sure that any object that then comes in contact with the cold brew is sanitized? is 60g of coffee good enough or should I add more? 2. What is the most efficient way of getting the most out of your vanilla? - Is soaking in vodka the best method? I was considering boiling 6 oz of water and steeping split vanilla bean for 15 minutes before adding it to the fermentor. 3. Should I add these things into the primary fermentor or would you [highly] suggest to move to secondary fermentation and them there? - I currently dont do secondary fermentation since most videos I've seen don't suggest it. I'll greatly appreciate any tips or tricks you might have.
