Awhile back I had posted about my RIS here https://www.homebrewtalk.com/f39/final-gravity-1-050-a-184087/ I ended up using the lalvin yeast suggested and the gravity went down about .006 points. Now I'm ready to bottle and I have another packet of the lalvin yeast. Can I add 6oz corn sugar and a fresh packet of yeast and get some carbonation. And another question: the recipe had 12.5 lbs. dark LME, 2 lbs. dark DME and 1 lb. dark brown sugar could the final gravity be so high (1.044, O.G. 1.130) due to the unfermenatables in the dark extracts?
