I am thinking about brewing the Northern Brewerkit. From the reviews, it looks like a lot of people add orange peel, cardamom, etc., and that caused me to have some general questions since I've never attempted to alter a kit.
Are there general rules of thumb for the amounts of fruit that should be added? Should all fruit be added in secondary? Do herbs, spices, and fruits have to be pasteurized or made sanitary some other way? Or does the alcohol present during secondary take care of everything nasty?
Other than fruit, I assume that some herbs and spices can be added during the boil, whereas others should be added later... kind of like how you do when cooking (flavorers first, aromatics last)?
I know that is a lot of info to ask, but most of the comments I can find searching around are mostly of the "just throw it in there" type. Being a chemical engineer, I can't quite make myself do that :. If you have an opinion about what fruit/spice additions to this saison kit would be good I'd very much like to hear about it. Leaning towards raspberries or blackberries, or maybe orange peel. Anyways, any help you guys can shoot my way is appreciated!
