Like an idiot I tried a Russian imperial stout as my first extract brew. Since then I have learned quite a bit from reading on this forum. The OG was 1.083 and we pitched one wyeast Scottish ale. 3 weeks later the FG was 1.027. Not knowing any better I bottled with 5 oz priming sugar and 5 weeks later there is zero carbonation. How do I handle this? Drink it flat and sweet? Wait it out at a higher temp(has been at 70), or sprinkle more yeast in each bottle and recap? Thanks in advance for your advice.
