IMPORTANT NOTICE: When using this vessel under pressure. You must perform a water pressure check to ensure your connections are leak proof. To do this. Fill your FermZilla up with water, then apply a minimum of 15psi pressure to the vessel.  Occasionally these units may come with some small indentations/dimples/dents from shipping, this is just a reality of shipping large blow-moulded thin-walled vessels. But dont panic, these fermenters are designed to endure minor deformations such as this.  All small dents will push out and settle with use and positive pressure and are only an issue and warrant replacement in the rare event they start to show white stress patterns.

Maximum temperature is 130 degrees F., if you pour boiling or near boiling wort into this unit, you will ruin it, and heat damage is not covered by warranty.

Good - needs More Fittings
Bottom line: I am sipping the first batch I made in the 'Zilla and it is flawless.  

The 27L 'Zilla works uncannily well.  After primary settled down, all the trub was down inside the well; I closed off the stopcock, unscrewed the well, dumped the trub, sanitized the well, reinstalled it, opened the stopcock, and in a day, a thick layer of yeast mud was on the bottom, ready to be used, stored, or discarded as you see fit.

It seems a clunky to use, but I think that just shows a need to get my new processes optimized.

It would benefit from a fitting on the well that allows draining from the bottom.  That could be a Corny Keg fitting with a nipple for tubing or maybe just a simple screw-on valve.

I do have the pressure kit, but I do not see a practical way to keep the 'Zilla cold, as in, serving directly from the 'Zilla.  Aging under pressure?  I will experiment with that next batch.

brew with greatness
this was a birthday gift to my son who lives in Iowa who has been brewing for sometime-however he has kids who suck up all his income-so i thought this to be a great birthday gift at a great price-plus you folks include the transfering kit (carb/caps). I also have this unit-and enjoy using it in brewing.  thanks again for the great deal.

Looks good but not better
I had fermentasaurus and i was looking for a second fermenter. All the upgrades that fermzilla had looked good. All the down side that you see in the videos are true. If you make sure that all the parts are airtight will be hard to disassemble. You have to use a lot of lube. If i have to do it again i will go for fermentasaurus.

Just used once and could not do the dry hop because I couldn't get the bowl off. The good is contingent on next brew that allows me to get the bowl off. I also feel that I couldn't completely shut the valve. I was reluctant to use to much pressure.

William's Responds: The valve closes all the way but you have to use pressure. It is very sturdy so don't worry about over pressing the handle.

Works as advertised but has quirks
Quite happy after one batch:

Get the pressure kit. Move beer from Fermzilla to keg using a hose with beer connectors on both ends, pressurizing Fermzilla a bit. (You have to vent the keg.) I got all the beer with almost no sediment. 

Unstrained pellet hops settled out in the collection jar, which was easy to clean and replace. To harvest yeast you might want to remove hops, which requires a small strainer or a funnel. The Williams funnel E37 could work but its strainer clogs too quickly.

My pressure kit came with metal fittings that accept beer- and gas-side connectors, though Williams tells me the manufacturer is switching to plastic fittings. I had to use a wrench to tighten these enough, even though the instructions say to finger-tighten. 

Instructions are not well organized or written. Example: the fermenter includes a handy sticker with volumetric marks (3, 4, 5 gals, etc.), but it's not clear whether these volumes are with or without the collection jar. (They are without.)

The PDF for the dimensions doesn’t reference how wide it is. What is the width in inches? Want to make sure it fits in my chamber.
The stand is 15.25" wide at its base, and 13.5" wide at its top. So you will need 15.25" of width to fit the unit.

A question from the less experienced, why pressurize the fermenter?
Many reasons, ferments under pressure can produce a smoother flavor and reduce esters. When done fermenting, the beer is carbonated.  Probably best to use a search engine and see a more thorough explanation.

One of the videos indicates the handles are a part sold separately. Is this the case?
Yes, we will have the handles in by November 25th. The part number is C69

Could you guys make something like this out of glass instead of plastic?
We do not think it is possible, unless it did not hold pressure.
