Mash King Tun With Bazooka Screen - 11.7 Gallon
11.7 Gallon Mash King Cooler Mash Tun
Alternative Views:

Mashing is the steeping process which hydrates the malted barley using hot water. This process is critical because it activates the malt enzyme, thereby converting the starches into fermentable sugar. The conversion of starch to sugar is carried out by the beta-glucanase and proteolytic enzymes.

During the mashing process, the starches become 90% soluble. This is done by heating up the grains in the liquid up to 130 degrees Fahrenheit. The grains should be milled to ensure that the starches are easily released into the liquid. The mashing process is carried out in a specialized brewing vessel called a mash tun. The Mash King Tun is a heavy-duty mash tun that can hold 11.7 gallons or 43 liters of liquid in one batch. Moreover, it still has more room to hold up to a 17% volume increase once the grain bill is mixed with the liquor or water.

This particular mash tun comes with the necessary accessories such as the stainless steel ball valve and a heat-resistant silicone gasket to prevent leaks. It also features the collapsible handles for easy storage even in tight places. The package comes with a bazooka kit which is necessary to separate the grain from the wort. The bazooka screen prevents the grain from mixing with the wort during the boiling process. The bazooka screen is made from stainless steel mesh and can be easily installed at the bottom of the mash tun to automatically separate the grains when the wort is being drained through the spigot or ball valve. It comes with a convenient 1/2" barb to attach your hose for transfer.

The Mash King's inside dimensions are 19" x 13 1/4". With its outside dimensions(with lid) being 21 3/8" x 15 1/2".

Teflon tape not included. This product requires assembly.

Before installing the Bazooka Kit remove the Cooler Spigot on the Mash King to free up the installation hole.

4 of 5 Works Great, Assembly Difficult November 22, 2018
Reviewer: Evan from North Bay, ON Canada  
I had the same problem as Brian until I realized there is a gasket on the spigot you are not supposed to remove. Leave that clear silicon gasket in place and the nipple won't be too long. That said it's really tough got get the nipple to thread through the gasket. Another tip, wear gloves, that nipple will shred your hands. It maintains temperature much better than a mesh bag in the kettle, especially when brewing outside in a foot of snow. Some husks make their way through the bazooka screen, but it's not enough to worry about.

5 of 5 Quick and easy to assemble March 8, 2016
Reviewer: Alex C from Barrie, ON  
Got mine in today, can't wait to use it. Fit for the spigot is a bit tight as mentioned by another poster, but a little bit of slow wiggling and positioning and everything went through fine without any damage or extra components. Followed the instructions and everything came out nice looking and leak proof the first time.

5 of 5 Works perfect March 3, 2016
Reviewer: Anonymous Person from Calgary, AB  
This was super easy to assemble, and works exactly as expected. Hold the temperature the whole mash. Arrived in perfect condition. Only been doing 5Gallon batches, but it has more than enough room for 10gal batches!

4 of 5 Great once you get it together. January 15, 2016
Reviewer: Brian from Ottawa  
Customer service is amazing.  I had this tun delivered to Ottawa 20 hours after putting in my order.  

Regarding the Tun, I had to make a trip to the hardware store to buy an additional washer to get it to go together.  With the provided components, the nipple extends a tiny bit too far into the tun for the o-ring to seal.  Also, the nipple was a little too big for the hole, and I delaminated the lining of the tun around the hole when I forced it through.  Everything pulled together once I had the parts I needed to put it together, and there were no issues when I used it.        

In use, the tun is excellent.  The lid screws on securely.  The handles felt solid when lifting or moving it around when full.  No leaks.  It held my mash at 154 for 90 minutes with three lid removals for stirring and temperature checks.  The bazooka screen did exactly what it was supposed to.  Everything was easy to clean when finished.  

Really happy with my purchase.
