Is it even necessary to do the smack routine and wait for the contents to react? I had a situation on a current brew where the inner pack popped, but not enough contents mixed up and there was no reaction. I cut open the larger pack, also cut open the inner pack, mixed them in my starter jug and away I went. I guess I'm wondering why the manufacturer just wouldn't give us two separate packs that we open and mix. I presume it has to do with reducing the risk of infection, but we're all clean freaks here...at least when it comes to the brew.
