We're brewing a batch of C. Papazian's Holiday Cheer which calls for a stick of cinnamon & orange peels among other things. Anyone have experience with this recipe or a general recomendation when it comes to spices, fruit etc. in primary? They're added in the last 10 minutes of the boil, but I'm wondering if that's enough to impart flavors, and if it would be too much to leave in the primary. Thanks.
