I have been looking and looking and can't find an actual write up or much more than a few bland HBD discussions on Teri Fahrendorf's 1992 special Zymurgy article about closed system pressurized fermentation. I read other peoples articles including some on the initial credited creator Morton Coutts. If someone reads Zymurgy and has that issue, could they break it down for me. I assume she is reiterating what Coutts has done, but since I don't know for sure I will always wonder. I have been using this/similar technique a couple of beers now and love it, but would like to know if there is some more to this technique I might be missing. Many thanks if you can help me out. My last resort is spending $20+ on an old copy somewhere to read what I probably already know .
