Infection after 2weeks in bottles?

[IslandLizard]

now i get something totally new and distinct. It feels "wild" or "strange". It slightly overcarbs the beers that have this off flavour. And its so easy to detect. No matter the beer you feel it is there and its annoyng flavour. Over the course of week or so it gets stronger and stronger until it overpowers all other flavours in beer.

The over-carbonation and annoying flavors becoming increasingly stronger point to an infection due to bacteria or wild yeasts, from either new or lingering ones. Many/most will add sourness and unwanted flavors, very rarely anything positive.

Again, I have an inkling there could be something lurking inside your hoses. They can be among the most difficult to clean. They make long brushes, especially for that. Or put a short brush on a string or an electrician's fishing wire.

The big problem is, once beer gets infected it will infect everything it touches.

Bleach, yup!

Yes. This has to be the case. Infection. There is no other explenation.

Its either a bucket or siphon(especially the damn hose).
Glass bottles should be sanitary after hot pbw cleaning with brush, rinsing and soaking in starsan.
Buckets are easy to clean but bacteria may have some hiding places in plastic. But i belive it would have had noticeable off flavours before bottling if that was the case.. but 2 weeks after bottling.. it must be the damn siphon wich is the hardest one to clean.
Its probably strong bacteria that can stay alive with standard cleaners.

No one else to blame but me.

How one uses the bleach to clean equipment?

Dissolve enough bleach in water, throw in a bit of vinegar, stir, in the equipment goes!

At this point, I think you need to go with a high concentration. Dilute 1:10 in water. Soak for ten minutes. Rinse thoroughly. The working dilution has to be made fresh daily.

But it will come back unless you treat or discard get everything that might be contaminated, including previous batches of beer.

throw in a bit of vinegar

Yes. Acidifying the working dilution stabilizes the hypochlorite so it remains effective longer.

For now i must drink as much as possible as quickly as possible. Before they start to get off flavours. I have around 160 bottles to go...

Yes..for now i will take break from brewing for few weeks. Drink what i can and what stays fine i can drink slower.
Clean with bleach... start storing separetly from other things that is yet not cleaned.

And start from something basic. No dryhopping no whirpool hops or anything that adds more risk of infections. And when i get clean beautiful product then i can start adding back more variables into the game.

I will report back! And if you have more tips let me know.

(At least im happy i had made some damn good recepies and some of my friends had change to taste them before the off flavoures developed. Juat have to sort this damn resilient "bug" out)

it must be the damn siphon wich is the hardest one to clean.

Can you post a picture of your siphon and tubing? BTW, "tubing" = "hoses."
Ordinary vinyl tubing should be fairly cheap, perhaps replace?

IIRC, someone mentioned to use a piece of cloth on a string and draw that through your siphon instead of using a draw brush. Of course, to prevent scratching, always use a brush/cloth on wet surfaces, such as soaked in a PBW solution.

Buckets and such generally have smooth surfaces, they should clean, rinse and sanitize easily. I use a small washcloth and mop the Starsan onto larger surfaces (such as bucket sides) that can't be soaked or dunked.
