Hey just took a Fg reading on https://www.homebrewtalk.com/f68/dark-chocolate-stout-136707/ and i did the recipe but did 5 gallon with the same grain bill. went from 6 gallons preboil to 5 gallon my og was .0172 i used safbrew s-33 yeast. i add 8 oz of cocoa powder and 1lb of lactose to it 10mins before flame out. My fg is 1.036 which mean about 50% Attenuation i believe. should i pitch more yeast or bottle it i don't know if the lactose and cocoa add to the fg but i feel it is still to high.
