I am a week into fermenting an RIS with OG = 1.136. Pitched four packs of Wyeast Scottish Ale (1728) and blew the lid off my fermenter. That prompted me to do some more research and I found that 1728's tolerance is only 12%, attenuation 69-73%. Seems unlikely that I will get down to my target gravity of 1.034 because this would be about 13.5% ABV. Even if I do get the gravity down that low, I doubt I have a shot at carbonating this beer with 1728, even if I pitch fresh.
On the other hand, if I were to pitch a fresh vial of yeast with higher tolerance/attenuation such as White Labs WLP001, don't I risk bottle bombing due to remaining fermentables? Prime/Don't prime? Different yeast? What do I do?
