I was thinking that the total IBUs from an oz each at 15,10 and 5 would give me around 65-70IBUs.
I have also been trying like mad to find out what the composition of the blend is,but alas without result.
My first choice was Summit,but as my neighbour was only going to be in the area of SFcraftbrew,he got what he could.
So,I am now in a conundrum. To stick with the original 15,10,5 OR bitter with something else at 60 and dry-hop.
