Been grain brewing for decades and mainly use safale yeast .started using cornys two years ago . Had a couple of brews recently that looked ok going in the corny but then dispensed very cloudy and wouldn't even clear when racked into a bottle and left to stand for weeks ...got a feeling it's starsan?? Any clues ?

Re: Permanently hazy?
Never seen cloudiness caused by starsan.
Haze is caused by:
- Unconverted starch.
- Combination of malt protein and hop tannins/polyphenols - this gets worse when cold. Beer that has been fined in the boil can end up hazy when cold. Kept cold long enough this haze will become permanent. Dry hopping adds lots more tannins. Gelatin/isinglass when cold pulls out the haze.
- Bacterial infection. This is permanent and near impossible to fine out. But you should know this is the problem by taste.
- Other contaminants such as lubricant left on metal parts.

Re: Permanently hazy?
Make sure mash pH is between 5.2 to 5.6. Sufficient Calcium levels circa 150-200 minimum. Hard boil, kettle finings (Protafloc), fast chill, plenty of fresh yeast, crash chill 3-5 days and optional finings, gelatine is easy and works brilliantly. Finally time.

Re: Permanently hazy?
That's covered it all already. Hop haze will not clear no matter what you do. Very much sounds like an infection.
How do you clean your cornies?
Whats your method for transferring to cornies?

Re: Permanently hazy?
If the beer tastes fine, see if it clears at room temp: then it's chill haze. Simple solution is to make a gelatin solution, put it into an empty, purged leg and transfer your beer into it. That will fix your chill haze problem, and yeast turbidity problems, possibly some hop haze issues too.

Re: Permanently hazy?
Mmm! Thanks everyone . Always had crystal clear beer before ... but what have I changed recently .. experimenting with over night mash ... stopped crash chilling .. using much more late addition hop pellets. Clean cornys with starsan and rinse well . Going back to my old tried and trusted methods. Thanks again .

Re: Permanently hazy?
There's an issue, starsan doesn't clean, it is a sanitiser. It is also a no-rinse product, so you are basically putting sanitiser into a potentially unclean vessel, and then rinsing out any protection, and potential adding new bacteria.

Re: Permanently hazy?
Yes, that sounds very much like your problem.
Clean, rinse, then sanitise.
Clean with PBW or Oxi or anything else that will break down organic residue (except washing up liquid).
Rinse that off well with tap water and let it drip dry.
Then as a final step sanitise - starsan shouldn't be rinsed off, and needs 30 seconds to a minute of contact to be effective.

Re: Permanently hazy?
Do you clean with pbw every time? I normally just clean with warm water and a new sponge, then starsan. Pbw is pretty much by exception - when I feel the other method hasn't cleaned it or when there are stubborn stains that i don't want to scratch off.
Never enough time...

Re: Permanently hazy?
Yes, although I only use about half the recommended 7g per litre mix, and only need 5-10 litres or so or water to clean everything.Bad 'Ed wrote:Do you clean with pbw every time?
