Anyone ever mail-order some malt extract and have it arrive actively fermenting? I didn't even know that malt extract on its own could ferment, but I got sixteen pounds of rice LME recently from an online supplier (that shall remain nameless), and one bucket of it had popped open in the box. I thought it was just a leak or maybe a temperature/pressure problem at first, but when I opened it up it was actively bubbling and smelled quite yeasty. I resealed it, but sure enough the next day it had popped open again and spilled more extract onto the floor. The other bucket was also bubbling and yeasty-smelling, but it hasn't spontaneously popped its own lid off as of yet. Weird! That's gotta be some serious yeast that can ferment undiluted extract!
