This is my base stout. I always do something a little creative with it for flavouring. So far, there have been 3 variations. 3 split vanilla beans and 4oz cacao nibs in a bourbon tincture have made it into every variation. For my Oreo one, I did the tincture above and I added a bag of family-size Oreos to the mash. I also used Amoretti Artisan Flavouring, cookies, and cream 3-5 days prior to packaging For my S'more's one, I did the tincture above and used S'mores Amoretti Artisan Flavouring 3-5 days prior to packaging For my French Toast one, I did the tincture EXCEPT I added cinnamon sticks to the tincture. I also used Amorettie Artisan French Toast artisan flavouring.
