So ever since I started brewing, I've been using pellet hopes. Normally after the boil, I run the wort through a strainer into my carboy. Even with the strainer I am still left with a fair amount of hop matter in the wort, which hangs around until I transfer into a secondary carboy. I'm thinking it might be the cause of some slightly bad after tastes that arise in my beers. I've made the decision to try using more plug and whole hops so as to eliminate this left over hop matter so in the very least I will be eliminating one variable in my problem. But I was wondering what effects this left over hop matter can do to beer.
