Doing The Pliney Clone..

Finally! I have been wanting to do this clone for a long long time. In the recent issue of BYO Vinnie Cilurzo did an article on creating Double IPA's and shared a recent version of his famous Pliny The Elder recipe. His recipe had a simple malt bill and much different hop bill than other clone recipes. Notably omitting Chinook addition, Mash Hops and First Wort Hops. He had his mash efficiency at 80%, I average about 75% on my system. Still with the decrease in efficiency I was coming a little under both the SG of 1.070 and FG of 1.011. Increased the grain portions and really stepped up the sugar to keep this bad boy dry. Kettle hops act as a great filter for trub and break from the boil. I increased the amount of water to account for hop absorption so I am not left squeezing wort out. Also doing a Gypsum and Calcium Chloride mash salt addition to make the hops pop and get suitable brewing water for a lower SRM pale ale. Here is my modified recipe.
