Direct Fire Mash Kettle Set - 85L

An 85L bottom drain mash kettle with accessories designed for three kettle, direct-fired brewing systems. The mash must be recirculated with a pump during heating - manual stirring and mechanical agitators are not sufficient to avoid heat stratification or overheating. To avoid overheating and ensure accurate mash temperature, the pump must always be running when the heating element is on. By recirculating and with proper control, you can maintain the temperature of the mash and program your mash schedule.

Upon request we can supply the kit with our butterfly valve with ball handle instead of lever handle, and with EPDM instead of silicone gaskets.

Due to the variety of mounting and connection options, the set is sold without some necessary components. The choice of the brewing stand will affect how you mount the pump and connect it to the system. In the store you will find everything you need to completely assemble your dream brewing system. 

Here are some tips to keep in mind when setting up your new brewery:

• You'll need a pump to recirculate the mash, and a valve between the pump outlet and the sparge arm inlet to control the flow rate. The Blichmann Riptide pump has an integrated outlet valve for this. For the MP-15 or other pumps, you will need to add a valve on the output side of the pump.
• It is always easiest to make external connections with silicone tubing and hose barbs. For 85L and 115L sizes, I recommend using 1" hose barbs and fittings with 19x30 mm silicone hose. Don't forget hose clamps!
• For recirculation you need access to the bottom port. Kettle leg extensions are required for standard table tops. You can also build an open brew stand or buy one from us.
• Temperature control is necessary. Don't try to manually switch the heating element, it will cause temperature overshooting.
• The kit includes a single heating element. If you plan to maximize your brew size on a regular basis, you may consider adding a second heating element to shorten the wait time between mash stages. If you are using the 3v3p, you will need to add an additional external relay. The second heating element can also be manually switched. Contact us for more information.
• The heating element in this set include a 3m long connection cable with SCHUKO plug, but it is not pre-wired to the heating element. Please consult a professional electrician. You must make absolutely sure that you use a suitable RCD and a circuit breaker designed for the load!
• With an optional EINBREW controller you can set up to 9 mash stages and have your recipe automated by the controller. By circulating the wort during mashing, you can achieve stable mash temperatures. An 85L 3 kettle direct fire system requires the EINBREW 3V3P.

See the "frequently bought together" products below for some recommended additions to the set. 

System Design

For recirculation, you need access to the lower Tri-Clamp port. If you are using a regular table as a brew stand, you can easily do this with the 14 cm leg extensions (sold separately). Please note that 80-90 cm high tables may be too high to comfortably operate the kettle. Alternatively, you can bolt the kettle directly to the floor with our 45 or 65 cm leg extensions and footplates. You can attach the pump to the legs of the kettle with a pump bracket. You can also build your own brew stand or choose a high-quality brew stand from Craft Hardware in the store.

The direct-fired mash kettle uses the tall false bottom stand so that the false bottom is above the heating element and lower kettle ports. This reduces the grain bill you can use in the kettle. When calculating the mash volume, you should include the volume of water under the false bottom. You may need to mash a little thicker or add water to the mash to achieve the desired mash thickness.

Volume level at the top of the false bottom stand = 22.0 L
