About two months ago I spontaneously decided to use the second runnings of a dark bock to make a gruit. Not having a second carboy, I figured I'd let it ferment in my auxiliary boil kettle. While the bock fermented without issue, it seems as though a fruit fly or two found their way into my makeshift fermenter. I'm reasonably certain that the bug they carried in was lacto. So, while not actually having intended to brew a sour but being an avid reader of HBT's lambic section, I figured I'd let it ride and see what I get. So far, I've racked it once (into a glass carby I bought in the meantime), and it tasted fruity and sour, actually pretty good.
The question I have now is: howlong will it take to finish?
