Ss Brewtech Brew Bucket Review
The vessel that made stainless conicals affordable. One capability it lacks decides whether it is right for you.
The short answer
The Ss Brewtech Brew Bucket is the best entry point into stainless conical fermenting: a 40-degree trub cone and a rotating racking arm in polished 304 stainless at a price well below welded vessels. It is not pressure rated, so it cannot do closed transfer -- which is the single biggest reason a kegging brewer might want a different vessel.

The pitch
What makes this the default entry stainless conical
Before the Brew Bucket, moving from a bucket to stainless meant a welded conical at several times the price. This vessel compressed that gap: polished 304 stainless, a real 40-degree trub cone, and a racking arm, at a number that a committed hobbyist can justify.
Two features do most of the work. The 40-degree cone is steep enough that trub actually slides to the bottom rather than sitting on the slope -- a distinction that separates genuine conicals from vessels with a decorative taper. And the rotating racking arm is smarter than it first appears: instead of siphoning from above and hoping you stay clear of the sediment, you rotate the arm to just above the trub line and draw clear beer out through the wall. Less sediment in the keg, no siphon, less disturbance.
The limitation
No pressure rating, and that is decisive for some
The Brew Bucket’s lid is a silicone-gasketed atmospheric design. It is not engineered to contain pressure and it must never be pressurized. That rules out two things:
- Pressure fermentation. No fermenting under 10 to 15 psi to suppress esters and ferment clean at warmer temperatures.
- Closed transfer. No pushing beer to a purged keg under CO2. You siphon, which means the beer meets air, which means hop aroma degrades.
Whether that matters depends entirely on what you brew and how you package. If you bottle, or you brew malt-forward styles where hop aroma is not the point, it does not matter at all. If you keg hazy IPAs, it matters more than every other feature on this page combined -- see best pressure fermenters.
Living with it
Three practical notes from owner reports
Chamber fit is usually fine
Unusually among conicals, the Brew Bucket generally does fit a 5 cubic foot chest freezer. Its cone is integrated rather than sitting on a tall stand, which keeps overall height down. Still measure -- the airlock needs clearance -- but this is one of the few conicals where the answer is usually yes.
The racking arm needs cleaning attention
It is a tube that passes through the vessel wall with a seal, and it is the part that soil accumulates in. Dismantle and clean it rather than flushing it, and inspect the seal periodically. The rest of the vessel is a smooth polished wall and is trivially easy.
It is heavy when full
Stainless plus 5 gallons of beer is not a one-person lift in any graceful sense. Decide where it lives and fill it there. A valve means you never need to lift it to empty it, which is part of the point.
Verdict
Who should buy it
Buy the Brew Bucket if you want stainless durability, trub separation and clean racking, and you either bottle or do not care deeply about hop aroma retention. It is our best-value stainless pick in best stainless conical fermenters and our best overall pick in best conical fermenters.
Buy something else if closed transfer is the point. A FermZilla with its pressure kit costs less and does it; a Spike CF5 costs more and does it in welded stainless. And if you have not yet sorted fermentation temperature, buy that first -- conical vs bucket explains why.

Mid tier
Ss Brewtech Brew Bucket
Ss Brewtech
A 7 gallon polished 304 stainless vessel with a 40-degree cone and a rotating racking arm that draws clear beer from above the sediment rather than siphoning around it.
Spec sheet
- Capacity
- 7 gal / 26 L (5 gal batch)
- Cone angle
- 40 degrees
- Valve
- Rotating racking arm, stainless ball valve
- Lid
- Silicone-gasketed, non-pressure
- Material

What it is not good at
Not pressure rated. The lid is a silicone-gasketed atmospheric design and must never be pressurized, which rules out closed transfer and pressure fermentation entirely.

What it is not good at
Much more expensive, and too tall with a stand for most chest freezers.
Who it is for
Brewers who want pressure capability and welded construction

Cheaper alternative
Mid tier
FermZilla All Rounder 30 L
KegLand
Pressure-capable with its kit for less than the Brew Bucket, which is the better trade if closed transfer is what you are actually after.
Spec sheet
- Capacity
- 30 L / 7.9 gal
- Shape
- Cylindrical (no cone)
- Pressure rating
- Rated for pressure fermentation with the pressure kit
- Material
- Clear PET
- Ports
- Ball lock posts, 4 in tri-clover lid option
- Weight
- Light enough to lift full-handed
What it is not good at
PET rather than stainless, so it scratches and has a finite life.
Who it is for
Brewers who want pressure more than they want stainless
FAQ
Questions brewers actually ask
Can you pressure ferment in an Ss Brewtech Brew Bucket?
No. The lid is a silicone-gasketed atmospheric design that is not engineered to hold pressure, and pressurizing it is genuinely dangerous rather than merely inadvisable. If pressure fermentation or closed transfer is what you want, you need an explicitly rated vessel such as a FermZilla with its pressure kit, a KegMenter or a Spike CF conical.
Will an Ss Brewtech Brew Bucket fit in a chest freezer?
Usually yes, which is unusual for a conical. Its cone is integrated into the vessel rather than sitting on a tall stand, so overall height stays manageable and a 5 cubic foot chest freezer typically takes one. Measure your chamber's internal height and allow an inch for the airlock before ordering.
What does the rotating racking arm on a Brew Bucket do?
It lets you draw beer out through the vessel wall from just above the trub line, instead of siphoning down from the top and hoping to avoid the sediment. You rotate the arm to the height you want and open the valve. The result is less sediment in the keg, no siphon to sanitize, and less disturbance of the yeast cake.
Is the Ss Brewtech Brew Bucket worth it over a plastic conical?
If you want a vessel that lasts decades and can be cleaned without worrying about scratches, yes. If what you actually want is closed transfer, no: a FermZilla with its pressure kit costs less and delivers that, which the Brew Bucket cannot do at all. Decide which capability you are buying before choosing the material.
