Hi, I'm about to make the Mangrove Jacks New Zealand Pale Ale beer kit. It is a cold filled malt extract beer kits that comes in a pouch. I wanted to add additional hops to increase bitterness. I know dry hopping won't achieve this, so I know i need to figure out a way to do this through boiling. However, you are apparently not suppose to boil these kits? So I was wondering if anyone had any advice on how to achieve this? Go ahead and boil it anyway? Or perhaps boil just the water with the hops and mix it with the extract after cooling? All advice/ideas welcome. Thanks.
