Funny taste

[Oscar Mild]

Hi all, I've recently started to use a corny keg, my first batch is disappointing, there seems to be a metallic taste to the brew. I'm using a beer engine, and 19 litres went Into the corny keg and the remainder went into a small barrel. The small barrel was fine...any ideas where I went wrong.

A beer engine is a beer pump, I steralised using VWP.I transferred the brew by turning on the tap at the bottom of my fermenting vessel, I carbed after purging the keg and put it up to about 25 psi for a week and the brew was a Geordie bitter the yeast came with it....be gentle I'm new to corny kegging. Thanks for your reply.

For starters on sorry to say vwp is a cleaner I think not 100 percent
The go to sanitizer for home e brewing is starsan check it out

This has got nothing to do with the flavour.
BUT
In my understanding, a beer engine draws beer up from a non-pressurised cask and dispenses it into the glass, while a corny keg is pressurised and quite unsuited to a beer engine.
SO
DId you dispense the beer from the cornie or the small barrel with your beer engine?

I thought that would be the reason somehow, damn I've just put another brew on using the same stuff. Thanks again for your reply, do you think the brew is safe to drink. ?

I used the beer engine with the corny and just used the tap on the plastic barrel. I've used the beer engine on a king keg before that was fine I used to gas that up too,that was fine. I transferred a stout from a king keg to the other corny keg and drew that via the beer engine and that was fine too....strange.

VWP is a Cleaner Steraliser, I use it regularly on cornies but its not great on stainless so you need to rinse it off thoroughly. After rinsing I then rinse with starsan, purge it out, pressurise and leave until filling with beer.

 

[labrewski]

Agh it's a sterliser but needs rinsing maybe that's the off flavour if not rinsed fully
I never have problems with starsan that's all I know lol

 

[trummy]

I have used VWP for years without a problem - I just rinse well with cold water.

Could be from your keg, is this the first time you have used it? There are a lot of cheap kegs on the market, a lot haven't gone through the passivation process leaving bare mild steel spots around the weld area.

Hi, yes this is the first time I've used the keg, it must be a few years old it's got west Germany on it. Will this taste go away the more it is used. ?

hello there - I had the same problem when I used VWP in a stainless steel keg, even though I did (I thought) rinse it carefully. I switched to using sodium percarbonate (this stuff) and never had the problem again… maybe a coincidence, but once bitten twice shy :-)

Thanks, I'll get some of that and star San and try them.

You will have to passivate the keg, that is what your problem is. The kegs have to be passivated periodically. You will need to give it an acid wash and the air will passivate it.

I've ordered star san, and by the looks I can passivate with a higher concentration of this, so I'll give it a go when it turns up. Cheers.

Gosh, where did you manage to find Star San - I didn‘t think it was still available in the UK

Remember DON'T RINSE,the air will passivate the keg as it drys out from the StarSan

I`ve ordered it from the malt miller. 8 0z for £17 ish.
