Hi all, I have been breweing for about 4- 5 years, i currently sanatise with phosporic acid and central Australian sunlight - something there is a lot of out here, this combination hasnt let me down until now.
I suspect that i know the orign of the infection is - most likely the cube or plate chiller - but i was wondering if any one had any idea on what type - variety - strain of infection my equipment may have accquired and how difficult it may be to kill.
After a 90 min boil i chilled as per normal - a 2 stage process via an imerrsion chiller (placed in boiling wort for 15 min) then through a plate chiller (i had that sucker in boiling water for 30 mins, drained and left in direct sunlight for 45- 60 mins before use) - wort into cube, no dramas, done this before. I checked the cube on Thursday arvo, which was being stored at 18d, and noticed that the cube had expanded somewhat - i released some pressure and noticed the foam that came out was very snot like - none to happy i tighted the lid, shut the door on the fridge to deal with it on the weekend.
So.....much to my dismay i poured out my previous Sunday afternoons work this morning. There was a bit of pressure behind the lid as the cube had distorted significantly, ( i did take photos but i forgot to replace the SD card in the camera - so no photos) - the substance that came out was a viscous slime with a head that reminded me of camel snot - not only in texture but volume, i could grab that slimey foam head a stretch that slime a good 20cm before it would break. The wort was thick,slimey, brown, with the occasional yellow spec/streak in it - the smell was one of cold baked beans, malt and cabbage - nothing very offensive.
All the hoses used in the transfer process, are all food grade, were in boiling water for 15 mins and rinsed in my phosporic acid mix and dried in direct sunlight for 45 - 60 before use. The tap on my brew kettle is flushed with boiling wort during the boil for 5 x 30 - 40 sec runs, the cube i transferred to had my usual phocporic acid treatment - about a litre in the bottom shake for about 40 seconds left to stand for a couple minutes - repeat 3 - 5 times, drain, stand upside down and leave in sun until inside is dry - add beer.
If anyone has any idea what the species/variety of infection is and a method to kill it - i am all ears.
Cheers,
DB
