Old Geezer's - Grand Duchess - RIS - BJCP Style 13 F - help

Grand Duchess - RIS - BJCP Style 13 F

This recipe originated from BCS by Jamil, Page 176-178 Tricentennial Stout. The original recipe has been changed by yours truly over the past 5 years. With the original recipe, BCJP Judges comments were not good. (My equipment was part of the problem and the fact I was a newby back then) After tr eking the recipe to match my brewing skills and equipment I started to get a few Medals/ribbons from various competitions.

The recipe posted with this is also tr-eked a little from the last recipe from which I have entered in 3 competitions during the month of March. The changes I have now made concern OG 1.106 to 1.095 and IBU's 100.0 to 90.0 (Jamils' recipes are based on Rager calculations for IBU's. Do I need to do anything other than give the Tinseth calculated IBU's desired other than input the desired IBU's?

Don't laugh to hard at this Old Geezer's 1st attempt at working with TheBiaBacus spreadsheet.

Appreciate any input from the experts. Hope to be brewing on the new system in 2-3 weeks.

Joe

Hi Joe

Short of time but I've attached a copy of your file. I've changed the amounts in section C to reflect the amounts in the book, plus I've changed the default efficiency to 70% as per the recipe. The Biabacus auto efficiency calculations are less accurate at higher gravities so 70 as per the recipe is a good starting point.

You also need to add you hop AA% when you get them in section D under substitutions. I can't answer the IBU question as it confuses me but I'd be happy with the 90 IBU setting.

Have a look and see what you think. As this brew is a couple of weeks away there is time for further tweaks.
