So i'm about to brew this IPA recipe using 10 lbs Briess Golden light DME. Beer smith has an ABV of 8.4% and I'm using 2 packets of SafeAle 05 because LBHS was out of Notty. Question: Will 2 packets of yeast have the same drying out effect as adding sugar would do? If I add sugar Beersmith says the ABV will go up to about 9%?
