Check your Alpha rating. If your bittering hop is rated more than 6 percent you may have a problem here. To start with. If your hop alpha is 14 percent, try just simply using half the amount. Some recipes are way over on the hoping. For some reason, Americans love to over hop their brews. To me, it taste like a bowl full of hops with water poured on it. The original IPA was propably made in a helmet in a trench on the battle field. ( Just joking.) The Brittish made beer for their conscripted soldiers. They did not spend a whole lot on the ingredients, including hops.
