I have been home brewing for three years and feel I am doing it all wrong. I have been trying to brew extract IPA's with whole leaf hops using SS mesh cylinders to contain the hops. I can stuff 4 oz of hops into each canister and typically on a 5 gallon batch, I will add at 60/30/0 minutes with 4 more ounces used to dry hop, 48 hours prior to bottling. I have been leaving the hop canisters in the single fermenter until bottling. Despite all of this, I do not get the hop zing one expects from an IPA. I suspect I should be using the whole leaf hops free floating in the boil and then allow the false bottom and tube strainer on the ball valve in my 10 gallon brew pot to filter out the hops from my wort. What do other home brewers do?
