K40 Mash Tun - Complete Set (incl. valves & clamps)

The heart of a real mash workflow — not a kettle you mash in.

The BrewTaurus K40 Mash Tun is a 48.1 L modular stainless mash vessel built for brewers who want real process control, predictable lautering and a system that scales without redesign. No integrated electronics, no proprietary internals — just brewhouse logic: mash, recirculate, sparge, lauter. Run it as infusion, HERMS or RIMS and build your system your way.

Made to order (pre-order). We build in monthly production batches — contact us for the current lead time before ordering.

Grain door — built for real brewing

This is the difference between a kettle you mash in and a mash tun you can actually work with.

Port architecture

• Recirculation return: 1× 1.5" TC (upper front)
• Lid port: central 1.5" TC
