I have only recently acquired Ron Pattinson's vintage book and have begun to read through his monumental blog. I'll be getting many more of his books.
One issue I'm having is that if simply transcribing his recipes into my brewhouse, as written, I'm getting much, much higher strengths and IBUs than he lists for his expected values. For instance, I'd love to do the 1915 Courage Porter. But on my system, according to his recipe (OG 1.050, IBU 36), I'm getting expected OG 1.061 and expected IBU of 54. Of course I don't expect an exact correspondence, or perhaps even a close correspondence, but the discrepancy here seems striking.
Am I missing something? Does anyone else have this issue using his recipes?
