Just finished brewing my favourite ale, (Fatyak clone). Almost always turns out very well. After I finished cleaning up, I had this niggling feeling that I had forgotten something. There was supposed to be a 0 minute addition of 12g of Nelson Sauvigon, and 12g of Cascade. What does a "0 minute" hop addition contribute, aroma or flavour? Do you think that dry hopping in the fermenter for a week or so with the same hopps would to some extent make up for my forgetfulness?
