here is a sort of unhelpful post. I have in secondary a Christmas Kolsch (Cranberry, spruce tip, and rosemary) I originally brewed five gallons of Kolsch, when transferring into secondary I split it into two 2.5 gallon batches. one to keep as a Kolsch, the other to make the Christmas experiment. I used frozen cranberry sauce that I made the year previously and froze. I added 3 cups of the homemade sauce plus the spruce tips and rosemary. I boiled the hell out of it for two reasons, kill all the germs and to extract the flavor of the spruce tips/rosemary. I just racked that into thirdary? (i.e separate fruit pulp, tips, and rosemary). the color looks great, smells great, and taste is good for a mostly fermented un-carbonated beer. I haven't noticed any issues with pectin or color....yet
