One stainless vessel. Mash and boil. Full process control.
The BrewTaurus K40 1V is a 48.1 L single-vessel electric brewing system in 304 stainless: K40 kettle with malt pipe, 3.5 kW of Tri-Clamp heating, one 15R pump. 20–35 L into the fermenter, up to ~10.5 kg of grain. Full sanitary Tri-Clamp architecture, no proprietary parts.
| Vessels | K40 kettle with malt pipe |
|---|---|
| Batch into fermenter | 20–35 L |
| Max grain bill | ~10.5 kg |
| Heating | 3.5 kW — 1× 3.5 kW |
| Electrical | 230 V · one dedicated, RCD-protected circuit |
| Pumps | 1× 15R — 16 L/min, 2.3 m head at 50 Hz, up to 120 °C |
| Wort chilling | not included — 1.5" TC outlet ready for an external chiller |
| Brim-full volume | 48.1 L |
| Guarantee | 2-year legal guarantee (EU consumer law) |
What's in the system
- K40 kettle: dished bottom, centred 1.5" drain, 1× 2" element port, 45° whirlpool port
- Stainless malt pipe / grain basket (31 L) — mash, lift, hang on the rim to drain, boil
- Heating elements: 1× 3.5 kW
- Pump: 1× 15R
- Sanitary 1.5" Tri-Clamp routing · stainless elbow + butterfly valves · thermowell in the bottom tee reads the recirculating wort
Not included: heating controllers (see Control below), wort chiller.
Heating & boil
- 1× 3.5 kW · one dedicated, RCD-protected circuit · heating controllers not included
- Heating pace: ~1.4 °C/min at 30 L — mash-to-boil (72→100 °C) in ≈20 min
- Boil: stable rolling boil, ~2–3 L/h boil-off
Grain & gravity
| Grain for 12 °P (OG 1.048) at 35 L | ~7.9 kg |
| Maximum grain bill | ~10.5 kg |
| Gravity at maximum grain, 35 L | ~15 °P (OG ~1.061) |
Mash thickness 2.6–3.2 L/kg; don't go below 2.3 L/kg. 7.6 L sits below the malt pipe and counts towards your strike water.
Hydraulics, cooling & cleaning
- 1× 15R for recirculation, whirlpool and transfer (16 L/min, 2.3 m head at 50 Hz, up to 120 °C)
- Pumps are not self-priming: mount them below the liquid level and flood the head before starting.
- No chiller by default — add a counterflow chiller on the 1.5" Tri-Clamp outlet.
- CIP: a 1.5" CIP spray head on a 1.5" lid port needs more flow than the 15R gives — use an MP-40RM pump for cleaning in place.
Installation: One dedicated, RCD-protected circuit — have a qualified electrician size and connect the circuits, water supply if you add a chiller, flat, load-bearing surface. Plan the electrical and structural preparation before delivery.
Control: K-Series systems ship without heating controllers. A dedicated BrewTaurus control unit for the K40/K80/K220 is in development and planned for release in spring 2027 — it will connect to the existing elements and pumps without replacing any vessel. Until then, use a third-party controller rated for the full current of each element.

1V vs 2V vs 3V — which K40 configuration
Same vessel size, same batch (20–35 L into the fermenter), three brew days. More vessels mean more grain, parallel steps and no lifting. Your configuration is highlighted.
| Config | Vessels | Max grain | Heating · pumps · chiller |
|---|---|---|---|
| K40 1V | kettle + malt pipe | ~10.5 kg | 3.5 kW · 1× 15R · no chiller |
| K40 2V | mash tun + boil kettle | ~13 kg | 3.5 kW · 2× 15R · counterflow chiller |
| K40 3V | HLT (HERMS coil) + mash tun + boil kettle | ~13 kg | 7 kW · 2× 15R · counterflow chiller |

FAQ
How big a batch can I brew?
20–35 L into the fermenter.
How much grain fits?
About 10.5 kg. A 12 °P beer at 35 L needs ~7.9 kg; at maximum grain you reach ~15 °P (OG ~1.061).
Do I need to sparge?
The batch figures assume full-volume (no-sparge) brewing. Sparging works too and lets you run bigger grain bills at the top of the range — heat the sparge water separately in a second kettle or an HLT. Tip: use your fermenter. If it has a 2" Tri-Clamp port, fit a 2.2 kW or 3.5 kW element (keep it fully submerged) and heat the sparge water in it — no extra vessel to store, and the hot water sanitises the fermenter before the wort goes in.
Do I need a hoist for the malt pipe?
At full grain the malt pipe weighs more than 25 kg even after draining. Hung on the rim to drain, its top sits 1086.9 mm above the floor; to lift it fully out, the pipe bottom has to clear the rim, so plan at least 1.17 m to the top of the pipe (rim + pipe height) plus room for your hands or hoist. Use heat-resistant gloves; a pulley makes it easier.
What power do I need?
1× 3.5 kW at 230 V, with one dedicated, RCD-protected circuit. Have a qualified electrician size and connect the circuits. Power control is external.
Does it come with a controller?
No. A dedicated BrewTaurus control unit is planned for release in spring 2027; until then, use a third-party controller rated for the full current of each element.
Can I upgrade to 2V or 3V later?
Yes. The kettle becomes the boil kettle; add the K40 Mash Tun (and the K40 HLT) — nothing gets replaced.
Product photos may show a prototype or a different size; production units follow the manufacturing drawing.
Gravity figures assume 70 % brewhouse efficiency (65 % at maximum grain); your mill, malt and process will move them.
