It's a bit after the event, but..... I had a batch of Belgian Strong Dark Ale that hasn't carbed up properly. I think that the primary yeast has just pooped out (it's around 11% ABV). There's plenty of priming sugar used. This morning I opened each bottle and added a few grains of champagne yeast to each before recapping. What are my chances of success?
