Barry’s in the middle of building his kegerator. He, oddly, has a few pieces set aside that he has no idea what to do with. Homebrew is that kind of operation, though, which is why we love it. In the meantime, I’m not doing squat.

I had planned to start Gowanus Brewery’s first all-grain batch today but ran into a major obstacle. I don’t have a way to lauter. Caught up in the details of the mash, I didn’t consider the relatively important steps of lautering and sparging.

Lautering follows the mash, which involves heating grains to make sweet wort. Lautering is draining off the sweet wort from the grains. It’s a simple step to define, but is complicated by the step that follows it: sparging. Sparging is rinsing the grains with water to maximize the total amount of fermentable sugars drawn from the grain. Lautering and sparging, as a practical mater, are interconnected, because the method you choose to lauter, i.e. the way you drain your sweet wort, effects your sparging, i.e. how much more fermentable sugars you can draw off your grain. There are a few different ways to lauter and each one requires special equipment.

I contacted customer service at Northern Brewer and was told that they don’t carry false bottoms for any of their MegaPots, which is what I’m working with. False bottoms, as I understand it, are ideal for the home operation. That leaves bazooka tubes. They aren’t perfect, but they get the job done. So, problem solved, I guess. I just have to wait until I get my hands on one, before I get to do any more brewing.

By the way, how great would it have been to be Tynes last night?!
