I had great luck with the farmhouse sour. I put a heat wrap on it, and I haven't finished the temp regulator I'm building for it, so it fermented in the 80s I'm guessing. Targeted 1.056 og and 10 ibus. I also pulled .5 gallon off the mash immediately and chilled it before it converted. I the. Added that to the boil. The plan was to give the bugs extra food. I also pitched dregs from a barrel works saison and an anchorage/hill farmstead Brett saison.
I sampled 2 months in and it had a bright lemony acidity, and had a great juicy mouthfeel. The gravity was stable 2 months after that and I bottled. The Brett has added a gentle funk, but the original flavor profile dominates, and is lovely.
Oh, one other thing I have stopped doing is aerating my sours. I think that, the low ibus, and the heat wrap all factored in the success of this beer.
I also have a turbid mashed sour going that I pitched melange into. I didn't catch how low the cell count was on the vial until I pitched, so it took forever to get going. We'll see where it is in another 8 months or so.
I want to try the funktown next.
