Hey there I've put down a nz pilsner from a recipe kit and it says to add hop pellets after 4 days of fermenting in my plastic fermenter. My question is do I just pop them in straight out the packet or do i put them in some kind of cheese cloth and make a teabag ? Also I don't have a secondary I use the primary as both fermenter and bottling. I'm worried I'm going to get bits of hops in my brew when I go to bottle. Cheers !
