Alright yeah I just saw that when I opened Beersmith I must have just overlooked it in Misc. I am attempting to design a 5 Gallon extract version of a 14th century gruit ale from gruitale.com and was hoping to be able to predict the relative bitterness of the final product. This i what I have for a recipe so far:
8g Sweet Gale
8g Wild Rosemary/ Labrador Tea
8g Yarrow
8# Pilsen Light LME
7.5# Carapils (this one I'm unsure of)
Wyeast 1028 - London Ale
From the All-grain recipe on the website the carapils and pale malt are 1:1 which is why I'm unsure of the amounts when it comes to an extract version.
