I have some uninvited guests in my latest batch of beer. Not experienced enough to know if they are good wild yeasts, bad wild yeasts, or something worse; but I'm looking for some advice as to what might be going on.
I have more photos and can take more if you all need more to work with.
The recipe was a What-If Summer Ale from Randy Mosher's Radical Brewing (that appears to have gotten a little too radical.)
Included grains of paradise and candied ginger at end of boil, used wort chiller, primary for two weeks in plastic food pail, and then two weeks in carboy secondary. Noticed this growth yesterday, but not a few days before (about 3) when I had last checked it.
What should I do? Thanks for the help.
