My Batch of Raspeberry Cream stout has been in the carboy in secondary fermentation for three (3) weeks. I was going to bottle tonight. Up untill two (2) days ago all was quite in the carboy, but two days ago very small bubbles started to rise to the top of the carboy. In the few other batches I have done, there was no bubbling what-so-ever when I went to bottle. Should I go ahead and bottle tonight or wait untill all the small bubble action stops completely?
