My Irish Red Ale. Picture of carboy neck is covered in krausen because of an early on active fermentation... Everything smells good. Verrrrryyyy, verrrryyy slight sour smell, but more like a yeast Co2 sour. Also may be more of a sulfur smell. I also smell some nice beer smell (my WH Honey Ale smelled like sweet apple when fermenting to me and turned out awesome when conditioned). The bubbles in the picture may look large but they are pretty small. This has been fermenting for two weeks.
