A friend wants to brew a Winter Lager this weekend. I pretty much know which way I'm going with it. But I need some suggestions for the spices and amounts/how to use them. I want to take a nice balanced Bock style recipe with some Wheat and add Orange Peel, Ginger and Cinnamon...only ingredient I have worked with has been orange peel. I'm looking to add them near the end of the boil. I don't want to mess with them post fermentation or do any tinctures. I want them to be a subtle addition to the complexity of the beer, I'm not looking to make a full on spiced beer.
But with ginger and cinnamon, what might be some starting amounts to go with? Also what might be a good % of Wheat to go with? I'm not looking to go full on Weizenbock, but the wheat sounds like it could be nice in what I have in mind.
