I think it's my fault guys. Just opened it to clean it and the krausen line is black and smells of metal. I'll be dumping this beer for sure. Is that mould too? 🙈

To save anyone else having this problem make sure you clean it half a dozen times!

This won't be happening to me again!!! Never had this problem with the other stainless steel fermenter I have.

I wouldn't blame yourself too much, the manufacturers should be held into account as well. The process of finished products made of stainless steel is degreasing before any pickling or in this case passivating the unit. So they didn't passivate it either.
The best thing to come out of this is to let others know not to be complacent and take things for granted when buying stainless SVBs and fermenters.
If you passivate it yourself let it air dry first. Don't rinse off with tap water use rainwater.

Told you it was the yeast.
 
Hi Tess,
Sorry to hear that your first batch fermented in the GF 30 is spoilt.
I have a GF30 and really like it and have used it for over 50 brews without any problems.
I can't remember how I first cleaned it; I have been a long time VWP user for glass and plastic but bought Kegland Stellarclean PBW when I changed to stainless steel. I probably filled the GF30 with water >50 deg C and dissolved the appropriate amount Stellarclean in it, momentarily opened the bottom tap and dump valve to fill them with cleaner and left to stand for a while.

Thoroughly rinsing with water after draining, I also gently use kitchen scouring pad green or white to remove any stubborn deposits.

My current cleaning regime after use is to thoroughly rinse with cold water, scrubbing off stubborn yeast deposits from the surface line.
I then pump from my brewzilla approx 30 litres of water 50 - 60 deg C and dissolve in 150g of Sodium Percarbonate, fit the lid and airlock and just leave it until the next brew.
Brew day I drain the GF30, while the boil is in progress, thoroughly rinse with cold water, add the cooled wort and pitch the yeast.

Stick with it it is a great piece of kit.

You would have thought that with amount that GF charge for them, that they would put them through an industrial cleaning process ! They should be fit for purpose straight out the box.
 
Thanks Jocky. I've always been curious about why everyone advised passivating stainless steel given the whole point of stainless is that the chromium forms a protective oxide layer in the first place. But I'm not a metallurgist. I had wondered whether it was just the echo chamber of internet forums repeating themselves.

I've never seen instructions on stainless steel cookware to passivate it before use, so don't know why brewery kit would be any different! (I didn't passivate my stainless kit and didn't have any issues (though did clean it with fairy before the first use).
The biggest problem is that stainless steel is a very generic term that covers many metal alloys. I have see stainless rust. Some stain some not. Price makes a difference. With knifes in its a big subject some alloys will sharpen well, others not so.
 
I was planning on getting another one in due course, but it certainly is making me think twice now.
I wouldn't let that put you off. The crud cleans off. Use it a few times first and then see how you feel about it.

As I've said elsewhere, the tap annoys me, but I will give it a few more goes because the integral heating/cooling is unparalleled (I have the little GC2 glycol chiller). Anything else would cost me at least £500 to get to the same functionality and I'd have a fermenter with a messy cooling coil in it.
 
I feel for you Tess, it must be annoying and frustrating wondering what had gone wrong, making you doubt yourself, as well as a waste of time and materials.

IMHO, its shoddy manufacturing. It is, after all, a product sold to the general public and unless described as needing specific preparation before use, you're entitled to believe that after a quick wash to remove dust etc, it's ready for use.

It's not as if it was being sold direct to a business that might reasonably be expected to have knowledge of potential problems and their own hygiene procedures.

If you buy a saucepan, (or a kitchen knife) , would you expect to have to degrease it and passivate? No. You'd unwrap it, give it a quick wash, put it on the cooker and chuck your spuds in. Anything less and it's not fit for purpose. Same with your GF. It wasn't described as needing special cleaning or preparation so you should simply be able to give it a quick wash and put it to use.

I'd complain to the maker or importer because something has obviously gone wrong in the factory.

Sadly, so much stuff is being subcontracted to China where the manufacturing standards can be very variable and the adherence to contractal requirements is sometimes 'discretionary' that these things happen, especially when the brand owner chooses to have things shipped to distributors rather back to their own offices for sampling inspection.

As I said, just shoddy. I suspect virtually every buyer would give it a simple wash and start brewing.
 
I agree they should make it known that more than a quick wash is needed.

The PBW clean that I did is not a quick wash I wouldn't say, when you count the soaking time and scrubbing. I have enough brewing experience to know when things are clean and sanitary enough. This product is a different ball game though. The oily stuff must've been super thick.

None of my kegs or the G40 had these issues so for that particular product it might be an idea for them to make the extent of the cleaning that's needed plainer.

Nevertheless I will keep going with it and I haven't fallen out with the product, just learned that things like this need more time and specialist products. It's all a learning curve and you never stop learning.
