The Monster Mash was a Brewyard Smash!

And by “brewyard” I mean the parking lot at Princeton Homebrew where 7 of us did a single mash to produce some 42 gallons of wort.

If you have been by Princeton Homebrew lately, you’ve probably laid eyes on the Monster Mash Tun. Its a 60-gallon, stainless steel homebrewers dream. The only problem is that we needed to create a false bottom to filter the grain from our beer. An effective false bottom is like a fine balancing act. If the filter is too course, grain husk will get through into your beer. If its too fine, all the grain will compact on the false bottom and prevent any water from making its way through the grain bed, resulting in worst of all brewing blunders, a STUCK MASH. So, you’d probably be thinking that we would pick a recipe to test our false bottom design that almost ensured success. Something like the brew we did last year at the Group Brew — a light saison with 9 lbs of grain per 5-gallons. Nahh, over several glasses of Hobo Juice at Princeton Homebrew, we decided the best idea was to Go Big or Go Home! We attempted to mash what will easily turn out to be the most difficult grain bill that this mash tun will ever see.

There were 17.5 lbs of grain for every 5 gallons of beer we were creating. And worse, 15 of them were brown malt — which basically pulverizes into a fine dust when milled. Setting the stage for a stuck mash.

Our false bottom combined high-end metal fabrication and items from the dollar store. Trenton Sheet Metal plasma cut a piece of 1/16 stainless steel and mounted hinges and stainless screen along with some 2-inch feet to keep it up off the bottom of the mash tun. And over drain we put a sink strainer over the top of an egg beater — no lie. Turns out our this last line of defense actually kept a decent amount of grain our of our wort!

A special thanks to Sir Al Buck and his magical box of stainless steel sanitary fittings, tri clamps and gaskets! And of course, this day couldn’t have been possible without the vision, cheerleading and Hobo Juice provided by Joe Bair of Princeton Homebrew.
