Minibrew® MiniMash Lauter Tun 15

The MiniMash Lauter Tun is designed from the ground up as a Mash Lauter Tun for brewers. It is not a converted water jug or picnic cooler. It will last longer than GOTT or any converted cooler on the market.

The MiniMash is a round 15 gallon tank that will hold up to 35 pounds of grain. The tank outside measurements are 22 1/4 inches tall by 17 inches in diameter. The 3/32 inch screen holes are an ideal size for the establishment of a good filter bed. The MiniMash's 5/16 inch thick walls provide the mass for strength and good heat insulation. Based on BTU transfer rates high density polyethylene (HDPE) transfers BTUs slower than stainless steel. Sometimes in colder areas a blanket or neoprene cover for insulation is needed.

False Bottom. The true bottom is 12 1/4 inch diameter and 1 3/4 inches deep. The indentation near the bottom as seen to the right forms a ledge inside. A stainless steel bolt is threaded through a center leg with a wing nut and washer to seal the screen in place, tight against this ledge and the leg. A flat false bottom is ideal as a Lauter Filter. The wort (sugars) drain evenly across the screen making for a more complete mash. It will not sag or allow grain to pass into the true bottom. The top of the bolt is an ideal depth measurement for stirring. Now you can stir the grain without disturbing the filter bed.

Thermometer threads are strategically located for easy and accurate monitoring just above the false bottom. The hold down bolt end is above the stem of the thermometer so you know when you are near the bottom if you are stirring. Thermometer is included.

Sight Glass. This design is to assist in maintaining a balance between in, and out Hot Liquor flow.  When you know the liquid level, you will know how recirculating (RIMs) is progressing and when to add Hot Liquor. With the MiniMash, the variables of mashing are under your control.  The new sight glass is Teflon.  It is flexible for easy removal and cleaning.  Also included for the lid is the MiniMister, which when water is added through the lid will mist the Mash.  

Extra threads. Two extra 1/2 inch threads have been added to the back of the MiniMash. One is near the top right and one below the false bottom ledge. Use these threads for RIMs or any other creative ideas you may have. The top thread allows you to bypass the Sparge Head directly into the top of the grain bed. The extra lower thread can be used for specific gravity and pH testing.

Partial Grain Brewers. Extract brewers can add specialty grain to increase flavor.

Recipe Size. The MiniMash Lauter Tun 15 is designed for five and ten gallon recipes.

Making Extract. Take the big step and make your own wort. It will taste better. The choice represents more opportunities for great taste and fun. Our MiniMash was designed and developed by brewers concerned about efficiency, taste and repeatability.

  • Fully equipped with our durable Sight Glass.
  • Extra Threads. Two extra 1/2" threads located on the back of the MiniMash. One at the top and one at the bottom below.
  • Designed for use with both 5 and 10 gallon size recipes.

    Using this tun for almost ten years now.

    Like other review, great for mashing and even fermenting, which I’ve done a time or too. It’s sturdy a pretty light weight for the most part, holds plenty of grains. Since I can brew only outside, wish there were an insulated jacket for one of these. The price difference now compared to when I bought it I think around 2016, maybe $ 50.00. Not bad at all.

    Absolutely Perfect

    There is quite literally no comparison between this and my old igloo cooler. This thing holds temp as well or better, is bigger so I have all the room I need for mashout and the sparge mist attachment is a godsend. Well worth the money. Could not be happier.
