M making a blueberry cream beer. Been fermenting in primary for 2 weeks time to add fruit or extract that's the question. If I add blueberry extract will that give me strong flavor. I was originally going to add yeast killer and add frozen purée but would like to Bottle this one instead of kegging. Also frozen blueberries are. Expensive. Other question is how much extract for 5 gal batch if I go that way. Thanks for help in advance.
