How to Make Your Own Home Brewing Mash Tun
July 26, 2014 by
A mash tun is a vessel, such as an
ordinary drink cooler converted for mashing, that is used
for heating grains in water to create a "liquor" rich with
sugars. It is these sugars that are converted to
alcohol during the brewing process. The grains a home
brewer typically uses are malted barley, but others can be
used - such as wheat, corn, oats, and rye.
New home brewers usually start brewing
beer by using kits. These kits come with malt extract
(dry or liquid). As such, there is no need for a
mash tun; the sugars have already been converted from
Experienced home brewers almost always use
the "all-grain" method, whereby a mash tun is
required. Instead of paying thousands of dollars for a
shiny, stainless steel mash tun used by craft
brewers, the home brewer requires something much smaller,
and much less expensive. That's why you always see
those orange coolers in the brew supplies store... you know,
those round "drink coolers" used by construction workers.
These drink coolers are modified to accept
a straining system, allowing the heated "tea" to be released
while the grains remain in the container. It is this
sugary tea that is boiled during the brewing process.
Voila! An inexpensive mash tun!
Although you can purchase one of these
ready-made mash tuns for a $150 or more, you can also
make one yourself - usually for about $75. And, that's
what this video is going to present. Learn how to make
your own mash tun for brewing beer at home.
