Revival mash tuns are built to order and are based on the customers specific design specifications. If you are new to distilling, don't worry, we have you covered! Our engineers can direct you to a design most suited to the spirits you will be creating.
The type of mash tun you choose will depend on the type of spirit you intend to produce. A bourbon or rye whiskey will require a mash tun that can mix thick mash as well as heat the mash. A mash tun designed for single malt (Scotch) style whisky will have a flat bottom with screens and rakes for lautering.

A false bottom is used to filter the liquid out of a bed of mash. This process is called lautering. The resulting liquid (wort) is free of solids.
Rakes and Plows
Rakes are used to gently brake up and agitate the bed of mash and to prevent channeling during sparging. Plows are used to push the grain out of the tun during grain out.
A grist hydrator sits atop the tank and is used to rapidly hydrate the milled grain, as it is fed into the tun. This prevents "dough balls" from forming in your mash.
A grain hopper is used to temporarily store grain prior to the grain being fed in through a grist hydrator.
Heating and Cooling Jackets
Heating and cooling jackets are added depending on your mashing routine. Heating jackets are typical for grain-in mash cookers. Cooling jackets can be used to cool mash to fermentation temperature eliminating the need for expensive mash heat exchangers.
If you are step mashing then you may consider automating the mashing sequence. Automation will improve consistency and repeatability in your mashing process.
Revival mashing systems are designed specifically for creating grain-in mash for distillation. With larger mixers and external heating jackets these mash tuns are designed to effectively heat thick bourbon and rye mashes. Automation options are also available for stepped mashing cycles. External cooling jackets can be applied to cool the mash in the mash tun before transfer to the fermenter. This eliminates the need for large hard to clean external shell and tube mash coolers.
For single malt (Scotch) style whiskeys, the mash tun is equipped with screens and a specialized mixer. The sugar-rich liquid that drains from the ports under the screens (wort) is then run through a heat exchanger before reaching the fermenter.
