Base or Complete?
Base ships with everything you need to brew — kettle, grain basket, fittings, brew pump, controller, and ULWD element. Complete adds the two accessories most Unibräu DrainPro owners buy in the first six months.
How will you cool wort to pitch temp?
A counterflow chiller knocks boiled wort to pitching temperature on the way to your fermenter. Pick one up here or bring your own.
Add a brew table?
Welded stainless table sized to your kettle, with the pump and plumbing mounted underneath. Matched automatically to the size you picked above.
The DrainPro difference.
One meaningful upgrade over the original Unibräu. Everything else stays the same — same architecture, same parts, same process.
Flat-bottom kettle
Trub and sediment settle across the entire flat base. Draining requires careful pouring or siphoning to avoid pulling solids into the transfer.
Sloped bottom drain
Sloped geometry directs trub and sediment to the drain point. Cleaner wort, easier separation, and simpler cleanup — every batch.
Five or six steps. One vessel.
Sparging is optional — Unibräu was designed to brew with or without it. Either way, it's one kettle from strike water to chilled wort.
Heat
Element heats strike water to your target mash temperature precisely and quickly.
Mash
Grain basket holds the grain bed. Pump recirculates wort continuously for even, repeatable conversion.
Sparge
Lift the grain basket and rinse if you want extra extraction — or skip it entirely. Unibräu was designed to brew with or without a sparge step.
Boil
Bring wort to a rolling boil in the same vessel. Add hops and finish your brew day.
Chill
Knock wort down to pitch temperature using your preferred method — or add the counterflow chiller for fast, efficient cooling.
Transfer
The sloped drain directs trub to the drain point, so clean wort transfers to your fermenter. To ferment in the kettle itself, choose the Unibräu All-In.

About the Unibräu DrainPro.
How is this different from the original Unibräu?+
One meaningful change: the sloped bottom drain. The original Unibräu had a flat base, which meant trub and sediment settled across the entire bottom and made cleaner transfers harder. The DrainPro's sloped geometry directs sediment to the drain point — cleaner wort, easier separation, simpler cleanup. Everything else (controller, element, pump, basket, TC architecture) is identical.
How long does a brew day take?+
A typical 10G batch is about 4–5 hours from cold water to chilled wort in the fermenter. The 240V system gets you to strike temperature roughly twice as fast as 120V — the difference is most noticeable on 20G+ batches. Cleanup is another 20–30 minutes; tri-clamp connections come apart in seconds for a full strip-down.
Will this fit in my space?+
The 10G is 18" diameter, 28" tall with element-out clearance — fits a standard countertop or rolling cart. The 20G is 22" × 34", the 30G is 24" × 38". Add 12" overhead clearance if you're using the steam condenser. All three roll easily on the optional cart, and the whole system can live in a garage, basement, shed, or apartment with a 240V or 120V outlet.
What's the difference between Basic and Complete?+
Basic includes everything you need for a complete brew day — kettle, element, controller, grain basket, pump, and all tri-clamp fittings. Complete adds the accessories most brewers buy within their first year: a sparge arm for even sparging, a CIP rotating spray head for clean-in-place sanitation, and a steam condenser to eliminate boil-off venting in tight spaces.
Can I ferment in the same vessel?+
Not in the DrainPro on its own. The Unibräu All-In is the DrainPro kettle plus a domed fermentation lid with a 15 psi PRV, cooling coil, solenoid, temperature controller and connection kit, so you pitch yeast and pressure-ferment in the same vessel. No second tank, no transfers.
120V or 240V — which should I order?+
120V (1,650W, SV1 controller) plugs into a standard North-American outlet — best for 10G batches and brewers who can't run a dedicated circuit. 240V (5,500W, SV2 electric brewery controller) needs a dryer-style outlet but heats much faster — strongly recommended for 20G and 30G batches.
What does shipping look like?+
Systems ship from our Vancouver, BC workshop and most orders go out in under a week.
What's covered under warranty?+
2-year warranty on the vessel, every weld and TC port, and on the controller and pump where they're included.
Heating element: 2 years against defects. Not covered: dry-firing (running the element without liquid covering it), and heat or melt damage at the twist-lock plug from a loose or improper connection — a proper, fully seated connection has to be maintained.
Temperature probe: 6 months — it's a consumable. Gaskets, clamps and O-rings are consumables too; replacements for all of these are in stock and cheap.
Lifetime parts support on everything we build — serviced, not replaced.
How does the Unibräu compare with Grainfather, Spike, Clawhammer and others?+
We put six all-in-one systems side by side, with prices and sources: all-in-one electric brewing systems compared. Head to head: Spike Solo vs Unibräu, Clawhammer vs Unibräu, Unibräu vs Grainfather, the Blichmann alternative page and our Ss Brewtech alternatives.
