Forgot to add hops during my boil


Dan Belmore asks,

I brewed on a Saturday. It was a perfect brew day and everything was going great! Or so I thought. Three hours later it occurred to me that I didn’t add the hops to the wort. I rushed to my fermenter and threw in one ounce of Cascade. Was this all right or is my perfect brew a wash? It was a Sam Adams duplicate.


There is not much great news to report on this unfortunate oversight. Hops need to be boiled to convert the insoluble alpha-acids into the soluble iso-alpha-acids. Unless the alpha-acids are “isomerized” during
