Most brewers spend a lot of time and effort keeping lactobacillus out of their breweries; it was the first thing we brought in (it still has to stay in the corner though). We blend together two different beers to make Troublesome. The first is a somewhat uninteresting wheat beer and the second is an overly acidic & funky beer fermented solely with lactobacillus. We blend the two beers together with coriander and salt at the tail end of fermentation to create a mild, lemony tartness and a fuller sensation of mouthfeel. And yes, it's hard to make.
