I am just getting started with brewing and I'm curious as to when I would add ingredients to Coopers extract brews. For example, I would like to make a pumpkin spice beer using the Coopers Wheat Beer as a base. Could I just brew the beer following the instructions and add the spices to taste when I transfer to the keg?
How about for adding hops? Since I normally wouldn't do a boil with these kits (besides boiling a gallon of water to mix with the extract in the bucket), and don't have a large brew pot, would it be ok to just throw the hops in for the desired amount of time with the gallon of water I boil and add to the fermentation bucket? Or is some interaction necessary between the malt and the hops?
How about adding fruit to these kits? For example, adding orange zest to a belgian wit.
Basically, I enjoy the simplicity of the Coopers kits and not having to do large boils, but I would still like to play with the kits and make some changes/enhancements.
