Hey all,
I have a cylindrical 10 gallon Gott cooler as my mash tun. For those
that also have the same setup, what is the maximum amount (pounds) of
grain you've been able to shove in this thing for a mash?
Thanks,
John

I just did 30 gallons, but it was a turbid mash. As it was explained to
me, that mashing process came about when Belgians were taxed on mash tun
capacity, so they'd cram their tuns to the top with mash. This forced
them to slowly cycle the liquid through in steps. That whole story
might be wrong, but I sure didn't have much room for water when it was over.

If I really push it and do a thick mash, I can get around 30lbs in
my 10 gallon cooler. It's pretty tight though.

In April I managed to squeeze in 23 pounds of grain at a water ratio of
1.25 qt/lb. in my Rubbermaid 10 gallon cylindrical cooler with a
perforated false bottom. Split batch: 3 gallon no-sparge barleywine/5
gallon batch-sparge braggot using two water infusions. Braggot is
being bottled this weekend.
One problem I ran into was stirring such a massive, dense mash. My
paddle broke in half after just a few passes through. I ended up using
a 6' long carpenter's level. With that I pushed in too deep and
disconnected the hose running from the false bottom to the spigot barb.
It was not fun reaching in to reconnect.

Use stainless steel braid or a Bazooka T-Screen with brass connections and
your problem will be solved. Having said that, I have no idea how these will
perform as far as efficiency goes under 23 pounds of grain. I have had good
results with this setup using about 18 pounds of grain and fly sparging.

In May I did a 15 gallon batch of Scottish Ale and just barely managed
to fit 28.5 pounds of grain and 7 gallons of water. That's roughly a
1:1 ratio of quarts to pounds. It was an insanely thick mash that was
so full that it almost formed a miniscus across the top of the tun.
The real bummer was simply how difficult it was to stir the grains into
the water... by the time I got to the last couple pounds, the whole
thing threatened to overflow the top every time I stuck the paddle into
the grist.
So, you can reach high 20s maybe even 30 pounds, but it is very
difficult to manage when the mash tun is so full. An alternate
approach to over stuffing the mash tun is to brew a concentrated batch
and dilute after boiling.

I might be wrong here too, but as I understand it Belgian breweries get
taxed on the gravity and qty of wort out of the mash tun, whereas most
other countries are taxed based on the final beer produced and the
'ABV' of the brew.
This can lead to breweries centrifuging and sparging hops to get every
last drop out.

Mark
