There are corrections to the Pliny The Elder recipe as it is printed in Zymurgy. The corrections are for the fermentables needed to achieve the 1.070 gravity.
You’ll need to change the recipe as follows. The recipe that was provided to us listed all the fermentable ingredients in percentages. The recipe is for a net of 5 gallons after the hops loss, but fermentables should be calculated for 6 gallons before hops loss.
This works out for 6 gallons at 1.070 with 75% efficiency and the proper % of each ingredient:
13.25 lb Pale Malt
0.6 lb Crystal
0.6 lb cara-Pils
0.75 lb corn sugar
From Vinnie:
I actually don’t have those numbers, I probably did at some point but it has been some time since I brewed the PTE as a homebrew recipe. Really that recipe is supposed to be a starting point for brewers to plug into their recipe formula and go from there.
