However... (you knew it was coming right) SWMBO wanted something different on tap, so I did a Hefe, fermented with 20 mandarine oranges. It's actually a fantastic beer. Edwort, I actually used your base recipe for this. You get the slight banana and clove flavors, but the oranges kick back with some acidity and tartness in the finish. However its really smooth, I know because I did 5 gallons this way, and 5 gallons left alone (mine).
OP... depends on what flavor profile your looking for, if you want more aromatic, add during secondary. If you want flavor, add during fermentation, and add A LOT! The yeast will scrub a bunch of the flavor/aroma away during primary.
