Beer brewing and wine making supplies

Build a Mash Lauter Ton

Moving to all grain brewing isn’t as hard as people think.  Anyone who searches the web for info on the subject will probably have their head spinning  from all the different variations on how to do it.  Teirs, circulators, pumps, wow!  This is all good stuff, but for the beginner, a little intimidating.   For myself, I like to use the KISS method (keep it simple stupid!)    There are really only two additional pieces of equipment that you will need to begin your journey into all grain brewing: a bigger brew pot and a mash tun.   The following are step by step instructions to converting a beverage cooler to a mash/lauter tun ( there are many ways to build one, so this one option).    It is extremely easy to do. It only cost $18.00 in fittings purchased at Carters,  $13.50 for a kettle screen (purchased here at the store),  plus the cost of the cooler purchased at Kmart.  A 5 or 10 gallon cooler can be used depending on how large a batch of beer you want to make.

The following are pictures and part names you will need to get:

hold reducer coupling with pliers and thread nipple in by turning the valve from outside (tighten snuggly).  Notice we had to bend the kettle screen to fit inside cooler.  For Larger coolers, this won't be a problem.
