Double batch of Flanders Red 2011:
What's the difference between the two beers? What strains did you use?
The left was only my house culture of bottle dregs (from the pic above). The right was only Roselare.
The house culture was by FAR my favorite, a lot more depth and acidity than the Roselare. I think it was because the house culture was very active when I pitched. Either way, house culture is how I'm doing it from now on. It produces more unique sours AND gives me a reason to buy good commercial examples.
