This white substance appeared on the side of my carboy but doesn't look like it is actually on the beer (only a few small bubble groupings on top of the beer). The substance appeared after I racked into a secondary after 12 days in the primary. It did have the strongest fermentation cycle I've ever had (actually blowing off the airlock in the first few days). Also after I racked the beer into the secondary it looked like it went through a second fermentation cycle. Any guidence would be appreciated.
