I made a blueberry wheat back in January. I used fresh blueberries and I think it turned out really well. Most people suggest 2 lbs. per gallon of beer and I used 1 lb. because I didn't want the blueberries to be over powering. I think next time I'll use 1 1/2 lbs. I just washed the blueberries then put them in a pot and ruptured them with a potato masher. Then I brought them almost to a boil for 10 mins to sanitize them. After that I tossed them in a fine mesh bag and racked on top of them in the secondary. I left the beer on the blue berries for 1 week. Hope this helps.
