I've got a batch of oatmeal stout (Midwest kit partial extract with the liquid yeast upgrade) in primary. The instructions recommend a secondary fermentation. I have just been much busier than normal in the last couple of weeks, and just haven't had a chance to rack it over. What's the worst that can happen? It's going on week 3 in primary, and still occasional action in the airlock. I've read about autolysis in mead and winemaking, where the yeast start to eat each other when they run out of fermentables, creating off flavors. Will this happen in a short time frame like beer brewing over 4 weeks? In general, what exactly does happen when you don't rack to secondary right away?
Thanks!
Thanks!
