Hi i just recently made an aggressive Imperial Stout with an OG of 1.120!! Well being afraid that the yeast i was going to pitch (WY 1028) would 'poop out' before finish fermenting, i added a package of (Red Star Champagne) yeast with the (WY 1028). Does anyone with experience know if this was a mistake or if i can brew this with desirable results? Thank you.
