So, t’is the season of brewing experiments, and today, I mashed in on a brew I’ll actually be boiling up tomorrow… that’s right, I’m trying a sour mash on a double-batch of beer for the first time. I’m only planning to leave the mash souring for 24 hours, mind you, but then again,  that’s not nothing. I figured, since I have a Farmhouse Ale Blend and a smack pack of Brett L., now would be a good time to try brewing with both… especially since I’ll have a nice population of Brett L. to spike a sour beer with later on. …
