So i have a Weisenbier going and i was planning on putting half a bottle of blueberry extract in before bottling but the more i read about fruit flavored i decided frozen fruits the way to go. So i boiled around 2 pounds of frozen blueberries and raspberry; not looking for too much flavor, and just threw them into the primary after 3 days. And im thinking about adding another pound in the secondary. What do you guys think about that. Did i screw anything up by adding them in half way though fermentation or what maby just added more time? And how does everyone else out there do it when they make fruit flavored beers?
