This seems a bit strange. Even the higher ciders I've brewed, with 3-5 lbs of honey added an a vigorous yeast have still tasted great after a year. Something tells me you are using a bad yeast and fermenting way to high to produce that amount of fusels. It's almost impossible to guess wihtout the specifics of your recipe and general fermentation temperatures. If it is in fact gasoline, I'll pay around $4/gallon for it. Oh wait, maybe $3/gal since the election is coming.
